Frequently Asked Questions
Q: What are the dimensions and load capacity of the 074658-001 bearing assembly?
A: The 074658-001 measures 20mm bore x 47mm OD x 14mm width and is rated for up to 5,000 lbs load capacity. These dimensions fit standard manual pallet jack wheel hubs from major OEM manufacturers. Verify your wheel hub bore and width match these specifications before ordering to ensure correct fitment.
Q: Which pallet jack brands and models use the 074658-001 bearing?
A: The 074658-001 is compatible with manual pallet jacks from Crown, Toyota, Raymond, Yale, Hyster, and similar OEM manufacturers. The bearing assembly fits standard wheel hub designs across these brands. Match the 20mm bore x 47mm OD dimension to your equipment before ordering.
Q: What material grade and hardness specification does the 074658-001 have?
A: The 074658-001 features races and rolling elements manufactured from SAE 52100 hardened steel, Grade G10 per ANSI/ABMA 19.8 standards. The raceways and balls achieve Rockwell hardness C58-63, providing durability for continuous warehouse duty with load cycles up to 120 per hour.
Q: What type of sealing does the 074658-001 bearing assembly have?
A: The 074658-001 uses double-lip rubber seals that are lubricated for life. This sealed design excludes dirt, moisture, and debris common in warehouse operations. The seals require no periodic relubrication and provide long service life under continuous duty.
Q: What is the expected service life and duty rating for the 074658-001?
A: The 074658-001 is rated for continuous duty warehouse operations with load cycles up to 120 per hour. With proper load application and no overloading beyond 5,000 lbs, expect 3-5 years of service life. Replace the bearing if it develops noise, radial play, or drag on the wheel hub.
