Frequently Asked Questions
Q: What are the specifications of SKU 88505?
A: SKU 88505 is a radial ball bearing assembly with 25 mm bore, 52 mm outside diameter, and 15.88 mm width. It features high-carbon chromium steel rings and balls with double rubber seals for contaminant protection in industrial environments.
Q: Which pallet jack models is SKU 88505 compatible with?
A: SKU 88505 is designed for manual pallet jack wheel and load roller assemblies in 8000, 87000, and 88000 series equipment. Cross-reference equivalents include NTN 88505, Peer 88505, National 88505, and JAF 88505. Confirm your OEM series before ordering to ensure proper fitment.
Q: What are the material properties of SKU 88505?
A: This bearing uses high-carbon chromium steel for both rings and balls, providing superior hardness and load-carrying capacity. Double rubber seals protect against dirt, moisture, and debris ingress. The sealed, single-row radial construction is standard for manual pallet jack load-bearing applications.
Q: When should SKU 88505 be replaced?
A: Replace SKU 88505 if you observe noise, play in wheel rotation, difficulty moving the pallet jack smoothly, or visible seal damage. The double rubber seals protect the bearing from contamination, but heavy-use environments may reduce bearing life. Preventive replacement during scheduled maintenance extends equipment reliability.
Q: Does SKU 88505 require maintenance?
A: SKU 88505 is factory-sealed and pre-lubricated, requiring no routine maintenance. Inspect seals periodically for damage. If seals are compromised, the bearing should be replaced rather than relubricated to ensure proper protection against contamination.
