Frequently Asked Questions
Q: What are the exact dimensions of bearing assembly 3308052?
A: This radial ball bearing assembly features a 20 mm bore diameter, 47 mm outside diameter, and 14 mm width. These precision dimensions are engineered for direct fitment in manual pallet jack load wheels and steering wheels requiring this specific size envelope.
Q: What equipment is bearing assembly 3308052 compatible with?
A: Assembly 3308052 fits multiple manual pallet jack models from Toyota, Crown, Raymond, Hyster, and other OEM brands. The 20 mm bore and 47 mm diameter are standard sizes used across many jack types, but always verify wheel bore diameter and mounting configuration before ordering.
Q: What material is this bearing made from?
A: The bearing races and balls are manufactured from hardened bearing-quality steel meeting precision specifications for load rating and fatigue resistance. This material withstands the radial and shock loads common in heavy-duty material handling equipment used in warehouse and dock environments.
Q: Why does 3308052 have double seals?
A: The double-sealed single-row construction protects internal bearing elements from moisture, dust, and chemical contamination encountered in warehouse, cold storage, and outdoor dock operations. Seals extend bearing life by preventing water ingress and maintaining internal lubrication integrity.
Q: How long will bearing assembly 3308052 last in normal operation?
A: With proper maintenance and typical warehouse duty cycles, this bearing assembly provides 5 to 10 years of service life. Heavy use, wet environments, or contamination can reduce service life. Sealed construction minimizes maintenance requirements and extends operational reliability.
Q: What cross-reference part numbers are equivalent to 3308052?
A: Cross-reference your equipment documentation for OEM equivalent numbers. The 20 mm bore, 47 mm diameter configuration is used by multiple manufacturers. Verify the exact part specification and load rating with your equipment manual to ensure correct replacement.
