Frequently Asked Questions
Q: What equipment does the PR 411B2-A load wheel assembly fit?
A: The PR 411B2-A is designed for BT Prime Mover electric lift trucks. Cross-reference part numbers PR411B2, PM411B2, and 411B2 are equivalent and identify the same assembly for compatibility verification.
Q: What is the durometer rating and material of this load wheel?
A: This load wheel assembly features polyurethane material with a 95A durometer rating. The 95A durometer provides hardness suited for standard indoor material handling operations on dry and level flooring.
Q: What bearing type is used in the PR 411B2-A assembly?
A: The PR 411B2-A includes precision sealed bearings that resist contamination and reduce maintenance intervals compared to open bearing designs. Sealed bearings extend wheel life in typical warehouse and manufacturing environments.
Q: How do I verify this is the correct cross-reference part for my BT Prime Mover equipment?
A: Check your equipment documentation or existing wheel for the part number. The PR 411B2-A is equivalent to PR411B2, PM411B2, and 411B2. All four numbers reference the same assembly for BT Prime Mover compatibility.
Q: What maintenance is needed for the sealed bearing design?
A: Precision sealed bearings require minimal maintenance. Inspect wheels periodically for wear, debris, or damage. Do not attempt to relubricate sealed bearings, as they are factory sealed for the service life of the wheel.
Q: When should this load wheel be replaced?
A: Replace the PR 411B2-A when polyurethane shows flat spots, chunks missing, significant cracking, or uneven wear. Worn wheels reduce load stability and increase stress on equipment. Bearing failure or noise indicates replacement is needed.
