Frequently Asked Questions
Q: What is a bearing cup, and how does SKU 150894 function?
A: SKU 150894 is a bearing cup that serves as the outer race of a rolling bearing assembly. It supports and guides rolling elements (balls or rollers) while distributing load across a wide area, reducing friction in wheel assemblies and drive components of electric lift trucks.
Q: Which electric lift truck brands use SKU 150894?
A: SKU 150894 is compatible with bearing assemblies on electric pallet jacks, walk-behind electric lifts, and sit-down electric forklifts from OEM brands including Crown, Toyota, Raymond, Yale, Hyster, BT, Jungheinrich, and Linde. Verify bearing size and shaft diameter match your equipment before ordering.
Q: What material is SKU 150894 made from?
A: SKU 150894 bearing cups are typically forged from alloy steel or chrome steel, hardened and ground to precise tolerances. Material selection ensures adequate hardness to support rolling element contact stress and resist surface fatigue under continuous load cycling.
Q: What are signs that SKU 150894 needs replacement?
A: Worn bearing cups produce grinding noise, rough rotation, or play in wheel movement. Visible surface scoring, spalling, or corrosion on the cup inner race indicates material degradation. Loose bearing cups cause wheel wobble and uneven wear on rolling elements.
Q: How long does a bearing cup like SKU 150894 typically last?
A: Bearing cup lifespan depends on load conditions, alignment, lubrication quality, and operating hours. Under normal electric lift truck service with proper greasing, expect 2,000 to 4,000 operating hours. Poor lubrication or contamination significantly shortens life. Bearing cups should be inspected annually.
