Frequently Asked Questions
Q: What are the exact dimensions and specifications of bearing assembly SKU 55002-6?
A: SKU 55002-6 is a double-sealed precision ball bearing with the following specifications: bore diameter 20mm, outside diameter 47mm, width 14mm, ISO Class P0 tolerance (normal), and high-carbon chrome steel construction. The double-sealed design provides contamination protection for manual pallet jack wheel applications.
Q: Which manual pallet jack models and manufacturers does the 55002-6 bearing fit?
A: The 55002-6 bearing with 20mm bore and 47mm outside diameter is compatible with standard manual pallet jack models from Crown, Toyota, Raymond, Yale, Hyster, Clark, and other major OEM manufacturers. Confirm that your equipment wheel assembly matches the 20/47/14 dimension specification before ordering.
Q: Why does the 55002-6 use a double-sealed design instead of single shield?
A: The double-sealed design of 55002-6 provides superior protection against water, oil, dust, and other contaminants that accumulate in warehouse, dock, and outdoor environments. Double seals extend bearing life and reduce maintenance frequency compared to single shield bearings, making 55002-6 suitable for harsh operating conditions.
Q: What is the typical service life of bearing 55002-6 under standard warehouse use?
A: Under normal warehouse conditions with regular use, SKU 55002-6 typically lasts 18 to 24 months before replacement is necessary. Lifespan depends on load, frequency of operation, and cleanliness of the environment. The double seal design extends life in wet or dusty conditions. Replace immediately if you observe grinding noise or wheel resistance.
Q: What material grade and quality standard does the 55002-6 bearing meet?
A: The 55002-6 bearing is manufactured from high-carbon chrome steel to bearing grade standards. It meets ISO Class P0 tolerance specifications, which is the normal precision class for material handling equipment. The steel composition and heat treatment provide durability and wear resistance for repetitive wheel rotation applications.
