• Construction and mining equipment wheel-end assemblies

Installation & Maintenance Tips:

1. Inspect the shaft and housing seats before installation. Check for scoring, wear, out-of-round conditions, or burrs; poor fits cause vibration, heat, and premature wear.
2. Always set correct endplay/preload during installation; it directly affects heat, noise, and bearing life.
3. Use proper lubrication (grease or oil) and keep contamination out—clean assembly matters. Avoid over-greasing in high-speed applications. Excess grease can churn, raise operating temperature, and shorten grease life; follow the equipment’s recommended fill amount.
4. Replace cone and cup together to maintain proper contact geometry and performance.
5. After initial run-in, recheck adjustment if the application calls for it (common in wheel ends).
