220003093

Frequently Asked Questions

Q: What are the specifications of SKU 220003093 bearing assembly?
A: SKU 220003093 is an OEM sealed precision ball bearing assembly with 20 mm bore, 47 mm outer diameter, and 14 mm width. The bearing features dual-lip rubber seals and high-carbon steel raceways with hardened steel balls. It is designed for manual pallet jack load wheels and steering wheels in industrial duty cycles.

Q: Which manual pallet jack models use this bearing assembly?
A: SKU 220003093 is compatible with manual pallet jacks from Crown, Yale, Toyota, Raymond, and similar OEM manufacturers that use 20 mm bore bearings. Verify the bore and outer diameter specifications match your pallet jack wheel assembly before ordering.

Q: What does the dual-lip rubber seal do?
A: The dual-lip rubber seals provide protection against moisture, dirt, and contamination entering the bearing raceway. These seals extend bearing life by reducing oxidation and corrosion of the steel balls and races. Sealed bearings require minimal maintenance compared to open-design bearings.

Q: How long does a sealed precision ball bearing last?
A: High-carbon steel construction provides long service life, typically 3-7 years in typical warehouse pallet jack use. Sealed design minimizes friction and wear, extending bearing life. Actual lifespan depends on load, wheel usage frequency, and floor conditions. Bearings with internal corrosion or visible seal failure should be replaced.

Q: What is the difference between load wheel and steering wheel bearing requirements?
A: Load wheel bearings handle greater radial load than steering wheels. SKU 220003093 is rated for both applications with its high-carbon steel construction and sealed precision design. The 20 mm bore supports the 47 mm outer diameter raceway, providing adequate load capacity for standard pallet jack operations.
