Figure 4: 4R100 Coast Clutch Drum. I normally offer the customer either option, of course the roller is a cheaper option but if it craps, the sprag is the upgrade and the initial savings were not worth it. 130. The needles in these bearings roll freely in one direction, but lock to transmit torque when the rotation of the shaft is reversed. 50 to 60. Angular contact ball bearing(70 series. Allomatic sprags are full-hardened, individually loaded, and made with high-quality maraging steel that provide higher fatigue limits than stainless steel. )The sprag clutch is a rolling-type bearing that uses drag rollers, which are activated by a spring that allows the element to rotate freely around another, until the moment the direction is reversed, since at that point it locks and it stop spinning. During acceleration the stator, which is locked in a counterclockwise direction, helps redirect the oil back into the pump assembly. For sprag clutches to function properly, the sprags must maintain contact with the mating surfaces while in the freewheeling state. Diameter: 25 mm - 110 mm. Estimated Ship Date: Dec 27, 2023 if.
