Frequently Asked Questions
Q: What are the key specifications of the AT JA 173 bearing?
A: The AT JA 173 is a 25mm radial ball bearing manufactured from hardened steel and pre-lubricated for extended service life. It is engineered for manual pallet jack load wheel and steer wheel applications on Atlas pallet jack models.
Q: Which pallet jack models does the AT JA 173 fit?
A: The AT JA 173 fits Atlas manual pallet jacks designated for this bearing model. The alternate designation is ATJA173. Verify your equipment model matches Atlas specifications before ordering to ensure proper fitment.
Q: What does pre-lubrication mean for bearing longevity?
A: Pre-lubrication means the bearing is factory-packed with grease before shipment, eliminating the need for initial lubrication. This extended lubrication formula reduces friction, dissipates heat, and protects bearing raceways and balls from wear. Pre-lubricated bearings are ready to perform reliably across extended service intervals in pallet jack applications.
Q: How is hardened steel material beneficial in the AT JA 173?
A: Hardened steel construction provides superior fatigue resistance and load capacity for the 25mm bore size. The hardening process increases material strength, allowing the bearing to withstand repeated loading cycles in load wheel and steer wheel positions without permanent deformation or fracture.
Q: What is the difference between load wheel and steer wheel bearing applications?
A: Load wheel bearings carry the full weight of the load and require maximum radial load capacity. Steer wheel bearings support directional control with moderate vertical load. The AT JA 173 radial ball bearing design accommodates both applications in Atlas pallet jacks, though load wheels typically experience greater stress and wear rates.
Q: How long does the pre-lubrication last?
A: Factory pre-lubrication typically provides extended service life under normal warehouse operating conditions. The exact duration depends on frequency of use, load magnitude, floor surface conditions, and environmental factors such as moisture exposure. Regular inspection for bearing noise or rough operation indicates when maintenance or replacement is needed.
