Pin Bushing | KBRPB1020SB

A King Engine Bearings pin bushing (also known as a piston pin or wrist pin bushing) is a precision-engineered component installed in the small end of the connecting rod to support the piston pin. Designed to operate under extreme load and continuous motion, these bushings provide a low-friction bearing surface that ensures smooth articulation between the piston and connecting rod. Manufactured using advanced bearing alloys, King pin bushings deliver excellent wear resistance, load capacity, and durability for both OE replacement and high-performance engine applications.

• Extreme Load Capacity – Designed to handle very high pressures (up to ~140 MPa) in piston pin applications.
• Low Friction Operation – Lead-enhanced alloy reduces friction between piston pin and bushing surface.
• High Wear Resistance – Engineered materials withstand continuous metal-to-metal contact and repetitive motion.
• Superior Heat Resistance – Maintains performance under high engine temperatures and combustion stress.
• Precision Press-Fit Design – Ensures secure installation and proper alignment in the connecting rod.
• Enhanced Durability – Tin and lead alloy composition improves fatigue strength and service life.
• Corrosion Resistance – Materials resist degradation from oil, heat, and combustion byproducts.
• Application-Specific Engineering – Designed for exact engine fitment across automotive, diesel, and performance engines.
• Supports Smooth Engine Operation – Maintains proper piston movement and reduces noise and vibration.
