Keystone License Plate Bracket

The Keystone Piston Wrist Pin Needle Bearing (also called a piston pin bearing or small-end needle bearing) is an engine bearing for the piston end of the connecting rod. It supports the wrist pin, also known as the piston pin or gudgeon pin. It lets the pin pivot smoothly as the piston travels up and down in the cylinder.

Key Features:

• Needle roller design uses thin, long rollers to carry high loads in a compact space
• Low-friction rotation helps the wrist pin move freely between the piston and connecting rod
• Replacement-style engine bearing for engine rebuilds and piston service
• Offered under individual part numbers, so you can choose the bearing for your application

Needle bearings at the wrist pin are usually replaced whenever a piston is replaced during an engine rebuild. A fresh bearing helps keep the pin and rod small end running smoothly. Choose the part number that matches your engine's application.
