Q: What are the dimensions and material specifications of 63052RS?
A: The bearing has a 25 mm bore diameter, 62 mm outer diameter, and 17 mm width. It is constructed from hardened chromium steel (SAE 52100) with a pressed-steel cage and nitrile rubber (NBR) seals rated for a dynamic load of 27 kN.
Q: Which pallet jack equipment is compatible with 63052RS?
A: The 63052RS fits manual pallet jack wheel assemblies from Crown, Toyota, Raymond, and similar major OEM manufacturers. Verify bore and outer diameter dimensions match your existing equipment before ordering.
Q: What is the load rating and durability of 63052RS?
A: The bearing has a dynamic load rating of 27 kN and is engineered for durability in industrial material handling environments. The double rubber seals protect against water, dust, and contamination, extending bearing life compared to open or single-seal designs.
Q: What cross-references are available for 63052RS?
A: The 63052RS is equivalent to 6305RS, 6305Z, and 6305-ZZ. It supersedes 6305RS2 and replaces earlier single-shield versions. Verify compatibility with your equipment documentation to ensure correct fitment.
