KBK connecting rod needle roller assembly

KBK is a specialized needle roller and retainer assembly for connecting rod small end piston pins (without inner/outer rings, only needle rollers and solid retainers), guided by inner diameter, with the piston pin as the inner raceway and the connecting rod small end hole as the outer raceway. It is suitable for connecting the piston pin and connecting rod small end of internal combustion engines, compressors and other crank connecting rod mechanisms, bearing reciprocating swing and impact loads, separating rollers and guiding motion with retainers. It is the core component of lightweight and high load bearing connecting rod systems.
