Product Description

The E312 sprocket is a critical wear part designed for excavator undercarriage systems, primarily used to drive the track chain and ensure smooth movement of the tracks. It is commonly paired with track chains (e.g., E312/E315 series) and works in conjunction with idlers, rollers, and sprockets to maintain proper track tension and reduce slippage.

Inner Roller/Spindle: Alloy steel (SCM440) engineered to withstand significant radial and axial loads
Seals & Lubrication: Nitrile rubber (NBR) seals for oil resistance with lithium-based grease for long-term lubrication
Quality Assurance: All materials undergo thorough inspection for chemical composition and mechanical properties using spectrometers and hardness testers
