Frequently Asked Questions
Q: What are the exact dimensions of SKU 3736692 bearing assembly?
A: This precision sealed bearing assembly has a 20 mm bore diameter, 47 mm outside diameter, and 14 mm width. These dimensions are critical for fitment on manual pallet jack load wheels. Verify these measurements match your equipment before ordering.
Q: What material is this bearing assembly made from?
A: This bearing is manufactured from bearing-grade chrome steel, SAE 52100 or equivalent. The material is surface hardened and precision ground to ensure smooth rolling surfaces. Chrome steel provides superior wear resistance and durability under sustained load.
Q: What equipment does this bearing fit?
A: This sealed bearing assembly fits manual pallet jacks with rated load capacities up to 5,500 lbs from major OEM brands including Crown, Toyota, Raymond, Yale, and Hyster. Cross-reference your equipment load rating before ordering.
Q: What is the benefit of the double-lip sealing design?
A: Double-lip sealing provides superior dust exclusion and moisture protection compared to single shield designs. This dual-seal configuration is essential for pallet jacks used in wet environments, cold storage, or outdoor areas where water and contamination exposure is high.
Q: What load and torque can this bearing handle?
A: This bearing is designed for high-torque rotating loads under combined axial and radial forces with a 1.0 service factor. It supports full 5,500 lb load capacity with smooth, consistent operation. Exceeding load specifications reduces bearing life significantly.
Q: How long does this sealed bearing assembly last?
A: Expected service life is 3 to 5 years in typical warehouse conditions, longer in clean dry environments, shorter in wet or high-contamination areas. Increased noise, grinding sounds, or resistance when pushing the pallet jack indicates bearing wear and need for replacement.
