Frequently Asked Questions
Q: What are the specifications of the BO 25057-A steer wheel?
A: The BO 25057-A is a 7 inch diameter steer wheel assembly featuring ultra-polyurethane tread, cast aluminum hub, and 25 mm bearing bore. This larger diameter wheel is designed for Boman SL series manual pallet jacks and provides improved maneuverability and floor contact compared to load rollers.
Q: Why is the steer wheel larger than load rollers?
A: The 7 inch diameter steer wheel is intentionally larger than 2.75 inch load rollers to enable directional control and turning of the pallet jack. The larger diameter reduces steering effort required from the operator and improves the turning radius during material handling operations.
Q: What material is the BO 25057-A hub?
A: The BO 25057-A uses a cast aluminum hub, which provides weight reduction compared to steel while maintaining structural rigidity. Aluminum hubs reduce overall pallet jack weight for easier maneuverability. The 25 mm bearing bore is precision-machined to ensure smooth rotation.
Q: Which Boman pallet jack models accept the BO 25057-A?
A: The BO 25057-A is compatible with Boman SL series manual pallet jacks. The alternate model designation is 25057AHD. Verify your equipment uses the BO 25057-A or equivalent SL series steer wheel specification before ordering.
Q: What is the difference between BO 25057-A and BO 25057-A-HD?
A: The BO 25057-A and BO 25057-A-HD are related assemblies with the same 7 inch diameter and aluminum hub, but the BO 25057-A-HD is designated as high-duty and includes enhanced specifications for demanding industrial applications. Do not assume they are interchangeable without confirming bearing bore and hub attachment method.
