Carrier roller failure causes chain sag, increased vibration, and progressive chain link and bush wear — a small part that creates outsized downstream repair costs when neglected. This earthmoving machine replacement part, the aftermarket carrier roller sk330, restores correct upper-chain support on the SK330 using OEM-matched dimensions throughout.

Compatible Machines
– SK330

Why Choose This Carrier Roller SK330
– Running diameter and flange width to OEM specification
– Bore and shaft dimensions confirmed to OEM: drop-in fitment, no machining required
– Bearing assembly pre-lubricated and sealed for service life comparable to OEM

Heavy-Duty Construction
This carrier roller sk330 is manufactured using high-strength steel shell with machined running surface and case hardening. Labyrinth-type external seals standard where fitted on OEM to exclude contamination. Mounting bracket and fastener geometry confirmed to OEM. 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
– Flat spots: cause chain hammering and vibration — replace immediately
– Bearing end-play: measurable axial movement means seal and bearing failure is imminent
– Oil leak from oil-bath rollers: seal failure causes rapid bearing deterioration
