Bearing Assembly - Single Shield

Frequently Asked Questions

Q: What is SKU F021156?
A: SKU F021156 is a single-shield bearing assembly designed for manual pallet jack applications. The single-shield design protects the bearing interior from one side while allowing maintenance access and periodic lubrication from the open side.

Q: Which pallet jack models use SKU F021156?
A: SKU F021156 is compatible with manual pallet jacks from Crown, Toyota, Raymond, Yale, and Hyster. It may be used in load wheel, pivot, or steering applications depending on your equipment model. Verify bore diameter, outer diameter, and width specifications against your original bearing before ordering.

Q: What causes a bearing assembly like SKU F021156 to fail prematurely?
A: Premature failure results from inadequate lubrication, contamination by water or dirt entering the open side of the shield, overloading beyond the bearing rating, or repeated shock impacts from rough flooring. Improper storage in wet conditions accelerates corrosion of the internal races.

Q: What is the material composition of SKU F021156?
A: SKU F021156 uses hardened steel for the inner and outer races and ball elements to withstand pallet jack dynamic loads. The cage is steel or brass alloy. Bearing grease is lithium-based or synthetic, selected for compatibility with the temperature range and duty cycle of your equipment.

Q: What is the expected lifespan of SKU F021156 in typical use?
A: Under normal manual pallet jack operation with scheduled maintenance, SKU F021156 typically lasts 2 to 5 years. Lifespan varies based on load frequency, surface quality, humidity, and lubrication intervals. In high-cycle or wet environments, replace sooner if rotation becomes rough or noisy.

Q: Can SKU F021156 be cross-referenced to other bearing part numbers?
A: SKU F021156 may have OEM equivalents from Crown, Toyota, Raymond, Yale, or Hyster. Cross-reference by bore diameter, outer diameter, width, and load rating rather than part number alone. Verify all dimensions match before substituting to ensure proper fit and performance.
