Frequently Asked Questions
Q: What is the load rating for the PW-684 idler caster?
A: The PW-684 is rated for 900 lbs load capacity per wheel. This rating applies to single-wheel applications on standard electric pallet jacks and walkie trucks. Total equipment load capacity depends on the number of idler wheels and equipment configuration. Confirm your truck load rating to ensure proper caster selection.
Q: What is the difference between the PW-684 idler caster and load wheels?
A: The PW-684 is an idler caster for steering and guidance, not primary load support. It features a 95A durometer polyurethane tread for traction and swivel capability on walkie and rider pallet trucks. Load wheels carry the primary equipment and load weight; idler casters guide and stabilize the truck during operation.
Q: What bearing type does the PW-684 use?
A: The PW-684 features precision sealed ball bearings that prevent dirt and moisture ingress. These sealed bearings are maintenance-free and suitable for general warehouse, light wet-floor, and standard operating environments. No re-greasing is required during normal service life.
Q: What electric pallet truck models use the PW-684?
A: The PW-684 is compatible with walkie and rider electric pallet jacks from Crown, Toyota, Raymond, Yale, and Hyster. The 5-inch wheel diameter and press-fit bore design fit standard idler-wheel assemblies. Verify your equipment model and caster bore specifications before ordering.
Q: What is the steel-core construction benefit of the PW-684?
A: The PW-684 uses a carbon steel core (ASTM A29 Grade) bonded to 95A polyurethane tread. The steel core provides rigidity and impact resistance for directional control, while the polyurethane offers grip and floor protection. This construction resists deformation under truck weight and extends caster life compared to soft-core alternatives.
