Description
Overview:
This 13 mm small end bearing is a genuine Husqvarna needle roller bearing for 2‐stroke chainsaw engines. It sits in the con-rod little end to support the piston (gudgeon) pin, delivering smooth, low‐friction movement at high RPM. Built with hardened steel needle rollers in a precision cage, it is made to factory tolerances for reliable fit and long service life. Ideal for routine top‐end servicing or when replacing a piston, it restores correct clearances and helps prevent scoring of the pin and con‐rod eye. Designed for Husqvarna professional and homeowner saws, including the 357XP and 455 Rancher, it is a direct replacement for the original part and suitable for use with modern unleaded/2‐stroke oil fuel mixes.
Key Features:
- Genuine Husqvarna part for fit, material quality, and correct clearances
- 13 mm internal diameter small‐end needle roller bearing for listed Husqvarna models
- Hardened steel rollers and robust cage for durability under heat and high engine speeds
- Low‐friction rotation to reduce wear on the gudgeon pin and con‐rod eye
- Direct replacement for OEM numbers for straightforward identification and ordering
- Compact design for easy fitting during piston or top‐end rebuilds (pre‐oil on assembly)
- Resistant to fuel/oil exposure in 2‐stroke applications for dependable performance
Typical Applications:
Used during piston changes, ring replacements, or full top‐end rebuilds on Husqvarna chainsaws. Suitable for preventative maintenance to address play or roughness at the little end. Helps maintain smooth running, stable idle, and consistent cutting performance in both professional forestry work and domestic firewood cutting.
