Single-Direction Thrust Load Path
The RCT337SA3-3-AM accommodates axial load in one direction only and must not be subjected to radial load. This matches the clutch release duty cycle: the bearing is thrust-loaded against the diaphragm spring when the pedal is depressed and unloaded (or lightly loaded) when the clutch is engaged. The thrust-ball configuration supports the rotational speeds and low friction torque required for smooth clutch actuation
