Bearing Assembly Single Shield

Frequently Asked Questions

Q: What are the bore diameter and width specifications of the 900890808 bearing assembly?
A: Bearing assembly dimensions vary by manual pallet jack model. Measure the existing bearing bore, outer diameter, and width to confirm SKU 900890808 will fit your load wheel spindle and mounting frame.

Q: Which manual pallet jack brands use the 900890808 bearing assembly?
A: This single-shield bearing assembly fits multiple manual pallet jack models from Crown, Toyota, Raymond, Yale, Hyster, and other common brands. Verify your pallet jack make and serial range against cross-reference documentation.

Q: What does single-shield bearing design mean and how does it affect durability?
A: Single-shield bearings have a metal or rubber seal on one side only, reducing contamination protection compared to double-shield designs. Single-shield bearings are suitable for indoor material handling but offer less protection in wet or dusty environments. Replace more frequently if equipment operates in harsh conditions.

Q: What is the expected service life of the 900890808 bearing assembly?
A: Bearing life depends on load, speed, and maintenance. Under normal manual pallet jack operation, expect 2-3 years of service. Failure symptoms include load wheel wobble, noise during operation, or load wheel seizure.

Q: What lubrication is required for this bearing assembly?
A: Most load wheel bearings come pre-greased and sealed. Check product specifications for relubrication recommendations. Over-greasing can cause seal failure and bearing contamination; under-greasing accelerates wear.

Q: Are cross-reference part numbers available for the 900890808 bearing?
A: Consult OEM parts manuals from Crown, Toyota, Raymond, Yale, Hyster, Jungheinrich, Linde, Clark, Mitsubishi, CAT, and BT for equivalent bearing part numbers. Ensure bore size, width, and load rating match before substituting.
