Frequently Asked Questions
Q: What are the dimensions and specifications of the BT 55001-A load roller?
A: The BT 55001-A features a 2.9 inch outer diameter, 3.25 inch width, and a 20 mm sealed ball bearing bore. It is manufactured from SAE 1045 high-carbon steel with Rockwell C40-C50 minimum hardness and a zinc-plated finish for corrosion resistance.
Q: Which BT pallet jack models does the BT 55001-A load roller fit?
A: The BT 55001-A is designed for BT L-series manual pallet jacks, including BT L2000 and BT L2300 models. It serves as a replacement load wheel in the roller assembly.
Q: What is the load capacity of the BT 55001-A roller?
A: The BT 55001-A is rated to support working loads up to 5,500 lbs under standard BT pallet jack configurations. Actual capacity depends on your equipment setup and maintenance condition.
Q: Why is the BT 55001-A made from SAE 1045 steel?
A: SAE 1045 is a medium-carbon steel that provides an optimal balance of strength and wear resistance for load wheel applications. The Rockwell C40-C50 hardness specification ensures durability under repeated load cycles while resisting deformation and surface damage.
Q: How does the zinc-plated finish protect the BT 55001-A?
A: The zinc-plated finish provides corrosion resistance, protecting the steel core from rust and oxidation in wet storage environments and outdoor use. This extends roller lifespan and maintains smooth operation.
Q: When should the BT 55001-A roller be replaced?
A: Replace the BT 55001-A when the roller develops flat spots, cracks, seized bearings, excessive runout, or visible corrosion beneath the zinc plating. These conditions degrade load capacity and jack maneuverability.
