Wössner Pistons Needle Bearing Bearings

Wössner Pistons needle bearings are replacement top end bearings, also called wrist pin bearings, piston pin bearings or small end bearings. They are made for two-stroke powersports engines. Each bearing supports the piston pin where the piston meets the connecting rod, so it can turn smoothly under high load and high RPM.

Key Features:

• Precision-manufactured needle bearing design for the piston pin and small end of the connecting rod
• Made as replacement top end bearings for Wössner forged performance piston kits
• Supports smooth, low-friction piston pin movement
• Sold as an individual bearing under its own part number
• Made by Wössner Pistons, a name known in motorcycle and powersports piston and engine components

Fitting a new needle bearing during a top end rebuild helps restore proper piston pin operation and reduces wear on the piston and connecting rod. Pick the variant with the part number and bearing dimensions that match your engine's piston pin and rod.
