Frequently Asked Questions
Q: What are the exact dimensions and specifications of this bearing assembly?
A: SKU 189245001 is a single shield bearing assembly with a 20 mm bore, 47 mm outer diameter, and 14 mm width. The bearing uses chrome steel SAE 52100 balls with a steel cage and single steel shield. These metric dimensions fit standard manual pallet jack load wheel and steering wheel hubs.
Q: Which manual pallet jacks does this bearing fit?
A: This bearing assembly is compatible with manual pallet jacks from Crown, Toyota, Raymond, Yale, Hyster, Clark, Mitsubishi, CAT, and BT that require metric 20x47x14 mm bearings in their load wheels and steering assemblies. Verify your pallet jack wheel hub bore and outer dimensions match before ordering.
Q: What material properties make this bearing durable?
A: Chrome steel SAE 52100 balls provide hardness and wear resistance under heavy load. The steel cage maintains ball spacing during operation. The single steel shield protects internal balls from debris and moisture. These materials allow the bearing to handle sustained pallet loads without early failure.
Q: How long does this bearing last in manual pallet jack applications?
A: In typical warehouse service with proper load capacity and maintenance, this bearing lasts 2 to 4 years before wear becomes noticeable. High-frequency use, overloading beyond rated capacity, or contamination with dirt and moisture accelerates wear and requires earlier replacement.
Q: Does this bearing require lubrication or maintenance?
A: This bearing comes pre-lubricated for initial operation. Monitor pallet jack wheel rotation for grinding sounds or increased resistance, which signal bearing wear. Replace the bearing if wheels spin roughly or become difficult to turn, as internal ball or race damage cannot be repaired.
Q: Are there equivalent bearing part numbers from other suppliers?
A: SKU 189245001 is our house reference for this 20x47x14 metric bearing assembly. To find equivalent OEM part numbers, reference your pallet jack manual or measure your existing bearing bore, outer diameter, and width to confirm compatibility before ordering.
