The use of additional “nylos” type seals is recommended especially when the working temperature exceeds 50°C. Picture going to an event such as a concert, fair, basketball or football game, where you pass through a turngate,. They will drive in one direction, and when rotation is reversed, or if the output rotated faster than the input, they. Precision ground v grooved ways and rollers provide high accuracy and load capacity. This imbalance can occur due to uneven distribution of weight on the tire or a misalignment of the tire and wheel assembly. The other type is "dimpled" to use a different type "roller clutch design" part that does the same job as the sprag, but is weaker- as is the lower count sprag that is used in some TH400's. , Ltd, is a manufacturer specialized in Producing Various One Way Bearings, One Way Clutch, Overrunning Clutch, Needle Roller Bearings.
