Precision Sealed Ball Bearing for Pallet Jacks

Frequently Asked Questions

Q: What are the specifications of the BMP4-117 sealed ball bearing?
A: The BMP4-117 is a precision sealed ball bearing with 20 mm bore, 47 mm outer diameter, and 14 mm width. It features deep groove construction, double-sided synthetic rubber nitrile seals, and is manufactured from case-hardened bearing steel conforming to SAE 52100 specifications.

Q: What seal configuration does the BMP4-117 have?
A: The BMP4-117 features double-sided synthetic rubber nitrile seals (2RS configuration) for protection against moisture, dirt, and contaminants. This seal design is effective in wet environments and cold storage applications common in warehouse and material handling operations.

Q: What is the precision tolerance class of the BMP4-117?
A: The BMP4-117 is precision-ground to ISO tolerance class P0, which ensures consistent bore diameter, outer diameter runout, and bearing radial clearance. This precision specification supports reliable rotation and press-fit installation in pallet jack hubs or axles.

Q: What material is used in the BMP4-117 bearing?
A: The BMP4-117 is manufactured from case-hardened bearing steel conforming to SAE 52100 specifications. The case-hardened construction provides a hard, wear-resistant outer surface while maintaining toughness in the bearing core for durability under high radial and axial loads.

Q: How is the BMP4-117 installed and what pallet jacks does it fit?
A: The BMP4-117 is designed for press-fit installation in manual pallet jack wheel hubs or axles with a 20 mm bore diameter. The double-sealed design eliminates the need for external bearing covers. No cross-reference part numbers are published by approved manufacturers. Verify your hub bore matches 20 mm before ordering.
