Frequently Asked Questions
Q: What types of manual pallet jacks is bearing assembly 851-200-805 compatible with?
A: Bearing assembly 851-200-805 is a standard OEM replacement bearing designed to fit multiple manual pallet jack models across common manufacturers including Crown, Toyota, and Raymond. Verify that the bore diameter, outer diameter, and mounting configuration match your specific equipment before ordering.
Q: What are the typical dimensions and material specifications for this bearing assembly?
A: OEM bearing assemblies for manual pallet jacks typically feature chrome steel races and balls per SAE 52100, with standard dimensions around 20mm bore, 47mm outer diameter, and 14mm width. Confirm exact dimensions for model 851-200-805 by cross-referencing your equipment documentation or the original part number specification sheet.
Q: How long does a bearing assembly typically last in manual pallet jack service?
A: Bearing assembly lifespan depends on load, frequency of use, and maintenance. In normal warehouse conditions, properly sealed bearings can provide 3-5 years of service. Failure symptoms include grinding noise, rough rotation, or lateral play in the wheel or fork assembly. If you observe these symptoms, bearing replacement is recommended.
Q: What seal type does bearing assembly 851-200-805 feature?
A: Most standard manual pallet jack bearing assemblies feature double-sealed (2RS) or contact seals to protect the bearing races from contamination. This seal configuration is suitable for typical indoor warehouse environments. For wet or cold storage applications, verify that your bearing assembly includes seals rated for those conditions.
Q: Can I use bearing assembly 851-200-805 as a replacement for other bearing part numbers?
A: Bearing assemblies are application-specific. Use part 851-200-805 only as specified for your equipment model. Cross-referencing equivalent part numbers requires matching bore diameter, outer diameter, width, seal type, and mounting style. If you need a cross-reference, verify dimensions and load ratings match your original equipment specification.
