Frequently Asked Questions
Q: What equipment does bearing assembly 570-379-418 fit?
A: This bearing assembly is designed for electric lift truck load wheels and steering wheels. It is compatible with electric walkie pallet jacks and stand-up forklifts from Jungheinrich, Linde, BT, Mitsubishi, and CAT. Confirm your truck model and wheel bore before ordering.
Q: What are the specifications for SKU 570-379-418?
A: Bore diameter is 1.375 inches. Bearing width is 1.125 inches. Load rating is 3500 pounds static. Dynamic load is 4200 pounds. This bearing assembly is sealed on both sides and filled with NLGI Grade 2 mineral grease. Races are AISI 52100 chrome steel.
Q: How long will bearing assembly 570-379-418 last in typical electric truck operation?
A: Expected service life is 3 to 4 years under normal warehouse use. High-cycle operations with continuous movement may reduce lifespan to 2 to 3 years. Sealed bearing design minimizes contamination and maintains performance. Inspect for grinding noise or rough rotation every 6 months.
Q: What materials and grease are used in bearing assembly 570-379-418?
A: Inner and outer races are hardened AISI 52100 chrome steel. Ball elements are precision-grade hardened steel. Double-shield seals are synthetic nitrile rubber. Grease is ISO VG 220 mineral-based NLGI Grade 2 formulated for ambient warehouse temperatures.
Q: Is bearing assembly 570-379-418 suitable for cold storage or wet floor operation?
A: This bearing assembly is rated for dry environments only and is not approved for cold storage below 40 degrees Fahrenheit or wet floor operation. Mineral grease becomes stiff in cold temperatures and reduces bearing life. For these applications, contact us for sealed bearing alternatives with synthetic low-temperature or water-resistant grease.
