Frequently Asked Questions
Q: What are the dimensions and specifications of the 4-inch wheel?
A: This wheel is. It is rated to support up to lbs at this size and features integrated sealed ball bearings for durability in electric lift truck applications.
Q: What materials are used in this wheel's construction?
A: The wheel uses a polyurethane tread with 75 Shore A hardness (±5 tolerance) mounted on an injection-molded polypropylene core. The integrated bearings are constructed from hardened steel and sealed to prevent contamination. This combination provides wear resistance and quiet operation across a wide temperature range.
Q: Which electric lift truck brands are compatible with this wheel?
A: This wheel is precision-manufactured for electric lift truck applications and is compatible with Crown, Toyota, Raymond, and Yale electric lift trucks. Verify the wheel mounting specifications match your equipment before ordering.
Q: What is the expected lifespan of the polyurethane tread?
A: The 75 Shore A polyurethane tread is designed for wear resistance and extended durability in electric lift truck service. Actual lifespan depends on operating hours, floor conditions, load patterns, and maintenance practices. The sealed ball bearings require no lubrication maintenance and are designed to perform reliably throughout the wheel's service life.
Q: Can this wheel be used in cold storage or wet floor applications?
A: The polyurethane tread maintains performance across a wide temperature range and is suitable for general warehouse applications. For specialized high-traction requirements in cold storage or wet floor conditions, verify material compatibility with your operational environment or consult our parts specialists for alternative tread compounds designed for those conditions.
