Bearing Assembly

Frequently Asked Questions

Q: What is the difference between the 2RS seal and metal shields?
A: The 2RS designation means this bearing has rubber contact seals on both sides instead of metal shields. Contact seals provide superior protection against moisture, dirt, and contamination compared to shields, making them better for wet environments and outdoor storage. However, 2RS seals may slightly increase friction.

Q: Which manual pallet jack models use the AK6307-2RS bearing assembly?
A: The AK6307-2RS fits multiple manual pallet jack models from Crown, Toyota, Raymond, and Yale. The 6307 size is a common configuration in mid-range load wheels and pivot points. Confirm your equipment model and bearing bore diameter to ensure correct fitment before ordering.

Q: Can I use the AK6307-2RS bearing in cold storage or wet dock applications?
A: Yes. The 2RS contact seals make this bearing more suitable for cold storage and wet environments than open or shielded bearings. The seals reduce water and ice contamination ingress. Ensure proper greasing intervals are maintained in freezing conditions, as lubricant viscosity changes in low temperatures.

Q: What is the difference between AK6307-2RS and AK6307ZZ?
A: Both use the 6307 bearing size but have different sealing methods. The AK6307-2RS has rubber contact seals for better contamination protection, ideal for wet or outdoor use. The AK6307ZZ has metal shields for general warehouse use. Choose based on your equipment environment and protection requirements.
