K Type Radial Needle Roller And Cae Assemblies
INCH SERIES
Radial needle roller and cage assemblies for connecting rod applications have two bearing positions: the crank pin or big end, and the wrist pin or small end.
In the crank pin position there may be severe operating conditions due to centrifugal forces, internal forces, accelerations and high rotational speeds, requiring the use of special radial needle roller and cage assemblies.
Similarly, in the wrist pin position the reciprocating inertia loads and high oscillating speeds dictate the use of special cage designs.
