Track pins and bushes are the bearing interface of the chain assembly — every chain link rotation happens at these surfaces, and their wear rate defines how quickly chain pitch elongates. This aftermarket track bush 445-0551 315/ex100 for the 315/ex100 is machined to OEM pin diameter, bush bore, and length specifications for a direct press-in replacement.

Why Choose This Track Bush 445-0551 315/ex100
– Pin outer diameter: OEM specification for correct link bore press-fit
– Bush inner and outer diameter: OEM for correct pin-to-bush running clearance
– Length: OEM dimension for correct chain width and link side-face clearance

Heavy-Duty Construction
This track bush 445-0551 315/ex100 is manufactured using alloy steel pins: case-hardened surface for wear resistance; tough core for bending load. Through-hardened bushes: consistent hardness distribution for wear life across the full bore length. Dimensional inspection of diameter and hardness before packaging. Designed to withstand vibration, impact loads, and harsh operating environments commonly found in construction, quarry, mining, and earthmoving applications. Precision manufacturing helps ensure correct fitment and long service life.

Applications
Suitable for a wide range of heavy equipment and undercarriage systems including:
– Excavators
– Dozers
– Loaders
– Track roller assemblies
– Earthmoving machinery undercarriage components

Maintenance Recommendations
– Use a hydraulic or mechanical press — never hammer press pins and bushes
– Replace pins and bushes as a set — mixing new with worn causes uneven wear
– Inspect link bores for cracking or deformation before pressing new components
