Frequently Asked Questions
Q: What bearing material is used in SKU 2640015 and what makes it suitable for manual pallet jacks?
A: SKU 2640015 is manufactured from hardened high-carbon chrome steel (AISI 52100 or equivalent) with a stamped steel cage. This material composition provides the hardness and wear resistance needed for manual pallet jack wheel assemblies in warehouse environments with repetitive loading and frequent directional changes.
Q: Which manual pallet jack brands and models does SKU 2640015 fit?
A: SKU 2640015 is a direct replacement for most standard manual pallet jack models from Crown, Toyota, Raymond, Yale, and Hyster. Verify the OEM part number 2640015 matches your equipment specification before ordering. Confirm wheel axle diameter and housing bore diameter match your existing bearing assembly.
Q: What is the expected service life of this bearing assembly in typical warehouse operations?
A: With proper maintenance and normal manual pallet jack operation (approximately 40-60 hours per week), this bearing assembly typically provides 18-24 months of service life. Lifespan depends on load consistency, floor surface conditions, maintenance intervals, and operational environment. Wet or corrosive environments may reduce service life significantly.
Q: What do the dual contact seals on SKU 2640015 protect against?
A: The dual contact seals provide protection against moisture, dust, and dirt ingress from warehouse floors. This is critical in environments with wet conditions, concrete dust, or chemical spills. The seals help extend bearing life and maintain smooth wheel rotation even in harsh warehouse conditions.
Q: How does bearing preload affect the performance of SKU 2640015?
A: This bearing assembly is designed for standard preload conditions common in manual pallet jack wheel assemblies. Proper preload maintains contact between rolling elements and raceways, reducing radial play and ensuring smooth, quiet rotation. Excessive preload increases friction and reduces lifespan; insufficient preload increases runout and wear.
Q: Are there any cross-reference part numbers for SKU 2640015?
A: Cross-reference numbers are not available for SKU 2640015. Use the OEM part number 2640015 to verify fitment with your equipment documentation. If you need to confirm compatibility with a specific manual pallet jack model, contact our technical team with your equipment serial number or OEM part documentation.
