Frequently Asked Questions
Q: What is the BA AW-4-1 idler caster compatible with?
A: The BA AW-4-1 is designed for Baker electric lift trucks. It replaces BABKAW-4-1, supersedes BKBKAW-4-1, and is equivalent to BABKAW41, BKBKAW41, and BKAW41. Cross-reference all numbers to verify compatibility with your specific truck model.
Q: What wheel material does the BA AW-4-1 use?
A: The BA AW-4-1 features a Durarun 95A polyurethane wheel. This polyurethane compound offers good grip, floor protection, and wear resistance for general electric lift truck applications including wet and dry floors.
Q: Is the BA AW-4-1 suitable for cold storage or outdoor use?
A: Standard Durarun 95A polyurethane performs adequately in moderate cold storage (above 32 degrees Fahrenheit). For extended freezer environments, specialized cold-compound wheels provide better traction and durability. Outdoor use exposes polyurethane to UV degradation; cover when stored outside.
Q: How do I know if the BA AW-4-1 wheel needs replacement?
A: Replace the wheel when you observe flat-spotting, deep cracks, chunks missing, reduced diameter causing ride height loss, or visible wear to 50 percent original thickness. Worn wheels reduce control and can damage truck steering geometry.
Q: What supersedes the BA AW-4-1?
A: The BA AW-4-1 supersedes BKBKAW-4-1. If you have stock of older BKBKAW-4-1 casters, the BA AW-4-1 serves as a direct functional replacement. Verify mounting and wheel diameter match before substituting.
