WJ 121616

The WJ 121616 clutch gear bearing from JERICO is a precision needle bearing engineered for high-performance dirt transmission applications. This compact steel component is essential for mechanics and off-road enthusiasts who demand reliability in extreme racing conditions. Whether you're building a competition transmission or restoring a performance dirt bike drivetrain, this needle bearing handles the radial and axial loads that come with aggressive gear engagement and rapid acceleration cycles.

Constructed from hardened steel with a natural finish, the WJ 121616 utilizes needle roller geometry to maximize load capacity within a minimal footprint—critical when space is constrained in high-RPM transmission assemblies. Needle bearings excel at supporting heavy radial loads while maintaining low friction and heat generation, making them the preferred choice for clutch gear applications where repeated engagement cycles demand durability. The bearing's compact dimensions (2.8 x 1.7 x 4.9 inches) and lightweight design (0.07 lbs) ensure it integrates seamlessly into JERICO transmission housings without adding parasitic weight that would compromise acceleration or top-end performance.

This bearing is ideal for restoration, repair, and custom build applications on JERICO dirt transmissions used in competitive off-road racing, desert buggies, and high-performance motorsports platforms. Proper installation requires careful alignment and appropriate bearing preload to prevent premature wear or noise. Technicians should always pair this component with complementary transmission seals, fluids, and gaskets to ensure longevity and optimal gear mesh characteristics in demanding operating conditions.
