Frequently Asked Questions
Q: What are the specifications of the 451022 bearing assembly?
A: The 451022 is a sealed ball bearing with a 20 mm inner diameter, 47 mm outer diameter, and 14 mm width. It features double rubber seals (2RS), bearing steel construction with case hardening to Rockwell C58 minimum, and ABEC 1 precision grade. This bearing is designed for manual pallet jack wheel applications.
Q: Which manual pallet jack wheel kits is the 451022 bearing compatible with?
A: The 451022 bearing is compatible with standard pallet jack wheel kits requiring a 20 mm ID bearing. It fits load wheels and steer wheels on equipment from Crown, Toyota, Raymond, Yale, Hyster, and similar manual pallet jack manufacturers. Verify your wheel bore diameter and outer race housing dimensions match the 20 mm x 47 mm specification.
Q: What makes the 451022 different from other 20 mm ID bearings?
A: The 451022 features double rubber seals (2RS) that provide enhanced protection against moisture, dirt, and contamination compared to open-seal designs. The case-hardened bearing steel at Rockwell C58 minimum provides superior hardness. The ABEC 1 precision grade ensures consistent bore and raceway tolerances for reliable performance in material handling equipment.
Q: How long does the 451022 bearing last before replacement is necessary?
A: With proper maintenance and regular lubrication, the sealed 451022 bearing provides extended service life in manual pallet jack applications. Typical bearing life depends on load frequency, environmental moisture, and operating conditions. Replace the bearing if you detect squeaking, grinding, resistance to rotation, or visible seal damage.
Q: Are there cross-reference part numbers for the 451022 bearing?
A: The 451022 is the standard part number with no known cross-reference equivalents currently available. If your pallet jack calls for a different bearing part number, verify the bore, outer diameter, width, seal type, and precision grade specifications.
