451013

Frequently Asked Questions

Q: What are the specifications of the 451013 bearing assembly?
A: The 451013 is a precision sealed ball bearing with a 20 mm bore, 47 mm outer diameter, and 14 mm width. It features hardened SAE 52100 steel construction with a press-fit mount. The bearing is rated for industrial material handling equipment including manual pallet jacks, load wheels, and steer wheels.

Q: Which pallet jack wheel kits use the 451013 bearing assembly?
A: The 451013 is compatible with manual pallet jack load wheel and steer wheel assemblies requiring a 20 mm bore bearing. This bearing fits standard pallet jack wheel kits from Crown, Toyota, Raymond, Yale, Hyster, and other major manufacturers. Verify your wheel bore diameter is 20 mm and outer race housing accepts a 47 mm bearing before ordering.

Q: What material is the 451013 bearing made from?
A: The 451013 bearing is constructed from hardened SAE 52100 steel with a machined raceway finish. SAE 52100 is a high-carbon chromium bearing steel that provides superior hardness and durability for high-load industrial applications. The precision finish ensures smooth rotation and long service life.

Q: How long does the 451013 bearing last in a pallet jack application?
A: With regular lubrication and proper load handling, the sealed 451013 bearing provides years of reliable service. However, bearing lifespan depends on load frequency, ambient moisture, and maintenance. Replace the bearing if you notice squeaking, grinding sounds, wheel drag, or visible corrosion on the outer race.

Q: Is the 451013 bearing interchangeable with other 20 mm ID bearings?
A: The 451013 is a specific bearing with defined dimensions and SAE 52100 steel construction. While other sealed ball bearings with 20 mm bore and 47 mm outer diameter may fit, material composition and precision grade affect performance. Cross-reference your OEM bearing specification against the 451013 before using as a replacement.
