Frequently Asked Questions
Q: What are the dimensions of the BG22053 ball bearing?
A: The BG22053 has a 20 mm bore diameter, 47 mm outer diameter, and 14 mm width. These dimensions are standard for manual pallet jack wheel assemblies and compatible with most traditional pallet truck designs.
Q: What material is the BG22053 constructed from?
A: The BG22053 is made from heat-treated SAE 52100 chromium steel with polished raceways. This premium material provides hardness and wear resistance necessary for the radial loads encountered in pallet jack wheel applications.
Q: What is the hardness specification for the BG22053?
A: The BG22053 meets a Rockwell C hardness minimum of 60. This hardness level ensures the bearing raceways and rolling elements resist deformation under the sustained loads of pallet handling operations.
Q: What contamination protection does the BG22053 offer?
A: The BG22053 features double-sided 2RS type rubber seals that prevent moisture, dirt, and debris from entering the bearing. This protection is critical for extending bearing life in wet warehouse and loading dock environments.
Q: What applications is the BG22053 suitable for?
A: The BG22053 is designed for shaft mounting in standard manual pallet truck wheel assemblies. The combination of SAE 52100 steel construction, double seals, and precision machining makes it suitable for general warehouse and material handling applications.
Q: How does the polished raceway finish benefit the BG22053 performance?
A: The polished raceways on the BG22053 minimize friction and reduce operating noise. This smooth surface finish, combined with the double rubber seals, provides quiet, reliable operation with minimal maintenance in standard pallet jack service.
