Frequently Asked Questions
Q: What does HD mean on the BO 25057-A-HD steer wheel?
A: HD designates high-duty grade engineering for demanding industrial material handling. The BO 25057-A-HD features precision aluminum alloy die-cast hub construction, chilled alloy steel bearings, and ultra-polyurethane tread at 95 Shore A hardness. This specification is optimized for high-volume operations and extended equipment life.
Q: What are the key specifications of the BO 25057-A-HD?
A: The BO 25057-A-HD features a 7 inch diameter, 25 mm bearing inner diameter, precision aluminum alloy die-cast hub with clear anodized coating, and ultra-polyurethane tread with 95 Shore A hardness. Bearings are chilled alloy steel for superior durability. This assembly is designed as a direct replacement for original Boman steer wheels in high-duty applications.
Q: What is the 95 Shore A tread hardness on the BO 25057-A-HD?
A: 95 Shore A indicates a firm polyurethane compound with excellent resistance to abrasion and cutting. This hardness is suitable for rough floors, debris, and high-speed directional changes. The 95 Shore A compound is harder than typical load roller compounds, extending service life in demanding warehouse and dock environments.
Q: What is the clear anodized aluminum hub finish?
A: Clear anodized is an aluminum surface treatment that provides corrosion resistance and aesthetic appeal without color. The anodized layer protects the die-cast hub from oxidation and wear. This finish is durable in both indoor and outdoor material handling environments.
Q: Which Boman pallet jack models use the BO 25057-A-HD?
A: The BO 25057-A-HD is designed for Boman SL series manual pallet jacks in high-duty applications. This wheel assembly functions as a direct replacement for original Boman steer wheels requiring enhanced durability and performance. Verify your equipment is SL series with 25 mm bearing bore before ordering.
Q: How do chilled alloy steel bearings enhance performance?
A: Chilled alloy steel bearings are heat-treated for superior hardness and load-carrying capacity. This bearing material resists deformation under heavy steering loads and provides extended service intervals. Chilled alloy bearings are the specification choice for high-duty industrial applications requiring maximum reliability.
