One Way Bearing is a type of rolling element bearing, inside the metal shell that contains lots of roller, needle or ball, and the rolling seat (hole) shape. So that one way bearing rotates freely in one direction and locks in place when turned in the opposite direction. The sprag rollers located between the two elements tilt slightly to lock into position and instantly stop the second element from spinning. ( Called "one-way" or one way cluch ).
Structure of CSK One Way Bearing Below:
CSK series one way bearing is a sprag type freewheel integrated into a 62 series Ball Bearing (except sizes 8 and 40). It is bearing supported, shipped grease lubricated and protected against dust larger than .012" (.3mm) diameter. recommended especially when the working temperature exceeds 122°F (50°C). The CSK type one way bearings are grease lubricated and sealed against coarse dirt. The 2RS types come with an integrated rubber lip seal for better dirt and moisture protection, they are a bit wider to accommodate for the seals.
APPLICATIONS:
One way bearing uses spring loaded sprag rollers that allow one element to freewheel around the other until the direction is reversed. it is often used in the automatic shift transmission of a motor car. also in various types of motorcycle, and hoist applications, and one way bearing is sometimes used as a backstopping device in certain kinds of conveyor systems.
One way bearing also comes into play as a backstopping mechanism in inclined conveyors. Loaded conveyors operating in an inclined position frequently attempt to run backward when the driving mechanism is stopped. In this application, the outer element attaches to the conveyor by means of a torque arm. The inner element of the clutch then turns freely with the forward motion of the conveyor. If the conveyor attempts to run backward, the sprag rollers are engaged and the motion is halted.
TYPES:
In addition to the basic CSK model. type CSK..P features a keyway on the inner race.
CSK..PP features a keyway on both the inner and outer race.
CSK..2RS
CSK . .2RS one way bearings clutches are .197" (5mm) wider than a standard 62 Series bearing, as they are equipped with lip seals for wash down applications .
CSK..P
CSK . .P has the same construction and outside dimensions as type CSK, but has a keyway on the inner race .
CSK..PP
CSK . .PP features a keyway on both the inner and outer race .
Installation of one way bearing
To prevent the inner ring and outer ring from slipping during the backstop operation, they have to be mounted with a firm press fit.
Please use an arbor press or hydraulic ram press which will exert steady pressure. Never use a hammer or other tool requiring pounding to drive the clutch into its housing. housing is rotated relative to the shaft in the direction of the arrow and LOCK marking stamped on the cup.

Mr. Wang, a responsible person of a mid-range vehicle fixed-point repair company in Chengdu Shamaojie Auto Parts City, recently told the author: “The prices of the auto parts are generally half or even less than the authentic ones, and the price is highly tempting, and they own the auto parts business. The same complete production and distribution channels... The water inside this area is very deep."
Fake raging
Auto market hides
There is a saying in the industry that when customers come to purchase accessories, the shopkeeper will directly ask “whether it is the original factory or the auxiliary factory?†This “original factory part†refers to the matching loading parts produced by the main engine plant. “Deputy factory parts†is Refers to the supporting parts produced by non-supporting manufacturers. The prices of most of the original parts are higher than those of the vice parts. Since the owners generally prefer the “original partsâ€, because the buyer will think that the original parts purchased in the auto parts market or the original parts that are replaced at the special maintenance stations should be the same as the original ones. In fact, the quality of the “original parts†sold in the auto parts market is uneven. Some auto repair stations also make use of the characteristics of auto spare parts specifications, varieties, and more manufacturers, the huge price gap, these charges. Taking a domestic brand oil filter as an example, a special repair shop is the original accessory, the price is more than 50 yuan, the comprehensive repair factory is a matching piece, the price is about 40 yuan, some roadside shop price is only 20 yuan, and some The quotation from the Auto Parts Market is as low as 8 yuan. The service of such accessories is of course difficult to guarantee.
Market confusion
Price packaging problems
At an auto shop in the auto parts city of Chengdu, a red cardinal shop in Chengdu, the owner of the shop heard that the author wanted to purchase the Jetta headlamps. He immediately asked whether it was the original factory or the deputy factory. The shop owner further stated that the original factory price was a uniform price of 295 yuan each; vice factory parts ranged from 50 yuan to 90 yuan each.
In Chengdu Xiaojiahe Auto Parts Auto Parts Auto Parts Store, the author noticed that there are a variety of lubricant brands and their price ranges from tens of dollars to several hundred dollars. The owner said that the cost of replacing the lubricant with the cost of replacing the oil filter will vary depending on the type of lubricant, ranging from RMB 30 to RMB 40, with more than RMB 100. Another store recommended to the author an imported lubricant, the cost is said to be nearly 200 yuan.
At an auto parts store in the “Maid Hat Auto Parts City†at Chengren intersection in Chengdu, the author stated that he would like to purchase the “Alto 368Q petrol pumpâ€. The owner enthusiastically recommended a gasoline pump produced by the Wuxi Huishan Auto Parts Group. The author noticed that the “manufacturer, batch number, production date†and other contents of the petrol pump are all readily available, but there is no shelf life. The owner said that the auto parts have no shelf life, only a three-month replacement period. Subsequently, on the car steering base manufactured by Shanghai Dizhixin Auto Accessories Manufacturing Co., Ltd., the author did not find any warranty period.
According to the author's survey, almost half of the products are not marked with manufacturers, origins, production dates, shelf life, product specifications, and methods of use, and some do not even have packaging.
Poor quality
What happens when someone loses his life?
Luomou, a professional agent of a veteran auto repair company in Chengdu, told the author that among all the bad parts, the real worrying factor was the “deputy factory partsâ€. Many bad parts wear quickly and have a short life; seals are not sealed and oil leaks; poor piston assembly quality results in pulling cylinders, blow-by gas, and burning oil; especially braking systems, steering systems, lighting systems, engine systems, and other critical components. It is very easy to cause a vicious accident that the car will destroy. For example, a bad fuse, after plugged in, said that it can accommodate 20A, but it will not blow when the current reaches 40A. Once the fuse can not limit the current, it will easily cause the automotive wiring harness to heat up, heat to a certain extent, the wiring harness will catch fire, and even cause the entire car to self-ignite.
Wang Lei, a staff member of Chengdu Association for Consumers' Association, introduced that in recent years, quality complaints caused by the use of counterfeit auto parts have increased significantly, and vicious accidents involving car crashes have occurred from time to time. After-sales service can not be synchronized with the development speed of the car, and manufacturers and service agencies are seriously out of touch, thus providing opportunities for these inferior quality auto parts products.
Original source
Fighting fakes from the source
Why is the inferior auto parts banned? Provincial People's Quality Supervision Bureau analysts said that mainly because it has a hotbed of survival and reproduction. In order to obtain maximum profits, merchants produce counterfeits and sell fakes. The owner of the company purchases and uses fake products to reduce the operating costs. The situation that the parallel imports and sales of parallel imports of goods in the market has thus occurred. In recent years, various law enforcement agencies in Sichuan Province have conducted joint operations and conducted centralized investigations and rectifications on the illegal and criminal activities of manufacturing and selling counterfeit auto parts, automobiles and motorcycle accessories, and assembling counterfeit automobiles and motorcycles. Achievements. However, in fact, unscrupulous merchants are still producing fake and inferior auto parts products, and quietly flow into the market. Anti-counterfeiting in auto parts work is faced with many difficulties: many auto parts sales points, long lines, wide areas, and everywhere, as well as serious local protection, make auto parts counterfeiting difficult; identify fake and shoddy products are too strong technical, too many specifications, complaints are difficult, evidence Difficulty, difficult to solve; a considerable part of the car is the consumption of public funds, the problem of exposure lags behind, masking the issue of counterfeiting.
A person in charge of the Chengdu Automobile Products Quality Supervision and Inspection Office stated that “to completely solve this problem, the focus of the crackdown should only be on the source of production, and the crackdown should be strengthened to ensure that the source is cleared.†
