CR 065081-31

Frequently Asked Questions

Q: What are the dimensions and seal specifications of the CR 065081-31 bearing?
A: The CR 065081-31 has an inner diameter of 1.181 inch, outer diameter of 2.165 inch, and width of 0.507 inch. It is equipped with dual seals featuring lip seals on both sides for contamination protection. The OEM part number is 065081-031.

Q: What equipment does the CR 065081-31 fit?
A: The CR 065081-31 is an OEM replacement bearing for Crown manual pallet jacks. Alternate model designations include CR06508131 and CR 065081 31. It is designed to fit wheel and axle assemblies on Crown pallet jack models.

Q: Why does the CR 065081-31 have dual lip seals?
A: Dual lip seals provide protection against dirt, moisture, and debris entering the bearing from both sides. This design extends bearing life in warehouse and outdoor environments where manual pallet jacks operate. Lip seals retain grease and exclude contaminants effectively.

Q: How does the CR 065081-31 compare to unsealed bearings for pallet jack applications?
A: Sealed bearings like the CR 065081-31 require less frequent lubrication and offer extended service life in dusty or wet environments compared to open bearings. The tradeoff is that sealed bearings may have slightly higher friction and cost more upfront. For manual pallet jacks used in varied conditions, sealed bearings typically provide better total cost of ownership.

Q: What is the expected lifespan of the CR 065081-31?
A: Under normal manual pallet jack duty, sealed bearings like the CR 065081-31 typically last 2 to 5 years depending on usage frequency, load weights, and environmental conditions. Heavy daily use or contaminated environments may reduce lifespan. Regular inspection helps identify wear before bearing failure occurs.
