Frequently Asked Questions
Q: What is bearing cup 6B5004 designed for?
A: Bearing cup 6B5004 is a tapered roller bearing cup that serves as the stationary outer race in manual pallet jack wheel assemblies. It works with a matching cone (roller race) to support the load wheel under load conditions.
Q: Which manual pallet jack models use bearing cup 6B5004?
A: Bearing cup 6B5004 fits various manual pallet jacks from Crown, Raymond, Yale, Toyota, and other OEM brands. Verify bore diameter and width dimensions match your load wheel assembly before ordering, as bearing cups vary by jack capacity and model year.
Q: What material is bearing cup 6B5004 made from?
A: Bearing cup 6B5004 is manufactured from alloy steel and hardened to withstand high radial and axial loads. The steel is precision-ground to tight tolerances to ensure smooth rotation and minimal bearing play in load wheel service.
Q: Does bearing cup 6B5004 require lubrication?
A: Yes. Bearing cup 6B5004 must be lubricated with NLGI Grade 2 grease suitable for wheel bearing service. Some load wheel assemblies use sealed cartridge grease while others require periodic manual greasing through accessible fittings.
Q: What is the typical lifespan of bearing cup 6B5004?
A: Under normal operating conditions with proper lubrication and alignment, bearing cup 6B5004 typically lasts 3 to 5 years. Lifespan decreases with overloading, inadequate lubrication, or rough floor surfaces. Replace cups showing visible spalling or bearing noise.
