Frequently Asked Questions
Q: What are the exact dimensions and specifications for bearing assembly 1045662077?
A: Bearing assembly 1045662077 features a 20 mm bore diameter, 47 mm outside diameter, and 14 mm width. It is manufactured from SAE 52100 case-hardened steel with dual contact (2RS) seals, hardness rated at Rockwell C60 to C64 on the raceways.
Q: Why is SAE 52100 case-hardened steel used in bearing assembly 1045662077?
A: SAE 52100 case-hardened steel provides superior wear resistance and load-carrying capacity required in industrial warehouse applications. The high hardness rating ensures the bearing raceway resists deformation under heavy pallet loads, extending bearing life significantly.
Q: What manual pallet jack brands is bearing assembly 1045662077 compatible with?
A: This bearing assembly is designed for standard manual pallet jacks across Crown, Toyota, Raymond, Yale, and other major hand truck manufacturers. The 20 mm bore and 47 mm outside diameter fit common load wheel hub configurations in industrial hand trucks.
Q: What does the 2RS seal configuration mean on bearing assembly 1045662077?
A: The 2RS designation indicates dual contact seals on both sides of the bearing. These seals protect the bearing raceway and rolling elements from moisture, dust, and contamination encountered in warehouse, dock, and outdoor loading dock environments.
