6307LLU

Frequently Asked Questions

Q: What are the dimensions and specifications of the 6307LLU bearing?
A: The 6307LLU is a double-sealed deep groove radial ball bearing with a 35 mm bore diameter, 80 mm outside diameter, and 21 mm width. These dimensions make it compatible with manual pallet jack load wheel and caster assemblies from major OEM brands.

Q: What materials are inside the 6307LLU bearing?
A: The 6307LLU features chrome steel rings and balls (SAE 52100 grade) for hardness and load capacity, a through-hardened chrome steel outer ring for durability, and a pressed steel cage for ball guidance. These materials provide long service life in manual pallet jack applications.

Q: What protection do the LL seals on the 6307LLU provide?
A: The 6307LLU uses double-lip rubber contact seals (LL designation) that prevent dust, moisture, and contaminants from entering the bearing while retaining factory lubricant. This is critical for warehouse, food storage, and outdoor environments where moisture and debris exposure is common.

Q: Which equipment types and brands use the 6307LLU bearing?
A: The 6307LLU bearing fits manual pallet jack load wheel and caster applications across equipment from Crown, Toyota, Raymond, Yale, and other major material handling manufacturers. Verify your equipment model and load wheel specifications before ordering.

Q: How does the pressed steel cage in the 6307LLU improve performance?
A: The pressed steel cage maintains precise ball spacing and distributes loads evenly across the bearing balls. This design reduces friction, minimizes noise and vibration, and extends bearing life compared to designs with less precise cage geometry.
