Product Specifications
CAT-E350/SF Track Roller Assembly: Technical Description
The CAT-E350/SF Track Roller Assembly is a critical undercarriage component designed for Caterpillar E350-series excavators. It serves to support the machine’s weight, guide the track chain, and maintain alignment during operation under high-load conditions.
Key Technical Features:
Forged Alloy Steel Core – Manufactured from heat-treated alloy steel for exceptional tensile strength and impact resistance.
Precision-Tapered Roller Bearings – Engineered to distribute radial and axial loads evenly, reducing wear and extending service life.
Multi-Lip Seal System – Integrates triple-layer lip seals with high-temperature-resistant grease to prevent contamination (e.g., dirt, slurry) and retain lubrication.
Hardened Outer Rim – Surface-hardened to 55-60 HRC to resist abrasion from track chain contact.
Threaded Bolted Flange – Allows for secure mounting to the excavator’s undercarriage frame using Grade 8.8 fasteners.
