Precision Sealed Bearing Assembly for Manual Pallet Jack

Frequently Asked Questions

Q: What are the dimensional specifications of the 48830-41H00 bearing assembly?
A: The 48830-41H00 is a precision sealed bearing assembly with a 20 mm bore, 47 mm outer diameter, and 14 mm width. These dimensions are engineered to fit standard load and caster wheel hubs on manual pallet jacks. Verify bore and outer diameter of your wheels before ordering to ensure proper fitment.

Q: What material is the 48830-41H00 bearing assembly manufactured from?
A: The 48830-41H00 is manufactured from high-carbon steel with hardened raceways rated to Rockwell C58 minimum hardness. Dual-lip seals protect the bearing from contaminant entry. This material specification provides durability for repeated load cycling in manual pallet jack applications.

Q: Which manual pallet jack models use the 48830-41H00 bearing?
A: The 48830-41H00 bearing is compatible with common manual pallet jack models from manufacturers including Crown, Toyota, Proplift, and Yale. This bearing fits both load wheels and caster wheels requiring a 20 mm bore. Confirm your equipment brand and model to ensure compatibility.

Q: What do the dual-lip seals on the 48830-41H00 do?
A: The dual-lip seals provide protection against water, dirt, and moisture ingress. This is critical in warehouse environments where floors may be wet or contaminated. Sealed bearings extend service life and reduce bearing replacement frequency compared to unsealed alternatives.

Q: How should I inspect and maintain the 48830-41H00 bearing?
A: Inspect bearings regularly for play, grinding noise, or resistance when spinning. Check seals for leakage or damage. Clean wheels and bearing areas periodically to remove debris. Replace the bearing assembly if seals fail, internal noise develops, or excessive play is detected. Properly maintained bearings provide reliable service for 2-4 years in typical warehouse use.
