6401190

Frequently Asked Questions

Q: What are the exact dimensions of bearing assembly SKU 6401190?
A: SKU 6401190 has a 20 mm bore diameter, 47 mm outside diameter, and 14 mm width. These dimensions make it compatible with standard load wheel and steering axle applications in manual pallet jacks from major OEM manufacturers.

Q: What materials is SKU 6401190 made from?
A: This bearing assembly is manufactured from high-carbon bearing steel with chromium steel precision-ground balls. This material combination provides durability and long service life in material handling applications, even under sustained load.

Q: How does the chromium steel ball construction benefit performance?
A: Chromium steel balls are hardened, corrosion-resistant, and precision-ground for consistent rolling characteristics. This design reduces wear on the bearing races and maintains smooth rotation under heavy loads typical in warehouse and pallet jack operations.

Q: Is SKU 6401190 sealed against moisture and contaminants?
A: Yes, SKU 6401190 is a precision sealed ball bearing. The seals keep moisture, dirt, and external contaminants away from the rolling elements, making it suitable for use in cold storage, outdoor, and wet floor environments.

Q: What pallet jack equipment does this bearing fit?
A: SKU 6401190 fits load wheel and steering axle positions in manual pallet jacks from Crown, Toyota, Raymond, Yale, Hyster, Jungheinrich, Linde, Clark, Mitsubishi, CAT, and BT. Verify the original part number on your jack before ordering.

Q: How does bearing size affect pallet jack performance?
A: The 20 mm bore and 47 mm outer diameter of SKU 6401190 are engineered for smooth rolling and load distribution in standard-capacity manual pallet jacks. Incorrect bearing size can cause binding, premature wear, or steering problems.
