Frequently Asked Questions
Q: What is the Durarun polyurethane compound used in the RA 631-051-004?
A: The RA 631-051-004 features industrial-grade cast polyurethane rated at Shore A 95 hardness. Durarun is a smooth-tread formulation designed for reliable performance under continuous service in electric lift truck applications.
Q: What are the exact dimensions of the RA 631-051-004?
A: The RA 631-051-004 has a nominal outer diameter of 5.00 inches, tread width of 2.880 inches, and bore diameter of 2.047 inches. These dimensions are critical for fitment verification on electric lift truck applications.
Q: Is the RA 631-051-004 a cast or molded polyurethane wheel?
A: The RA 631-051-004 is manufactured using cast polyurethane construction with a molded natural finish. Cast polyurethane provides superior resilience and load-bearing capacity compared to compression-molded wheels.
Q: Which Raymond models are compatible with the RA 631-051-004?
A: The RA 631-051-004 is manufactured for compatibility with Raymond electric lift trucks. No published cross-reference part numbers are available. Verify the 5.00-inch diameter and 2.047-inch bore specification against your equipment documentation for fitment confirmation.
Q: Does the RA 631-051-004 come with bearings installed?
A: The RA 631-051-004 specifications indicate a 2.047-inch bore. Confirm your bearing type and size with Raymond technical documentation or parts support before ordering, as bearing fitment is critical for proper wheel performance.
Q: What is the expected lifespan of the Durarun polyurethane tread?
A: Polyurethane tread lifespan depends on load cycle frequency, warehouse floor conditions, and maintenance practices. The 95A Shore hardness of the RA 631-051-004 provides durability for continuous-duty service. Monitor tread wear regularly and replace when tread depth falls below safe operating levels.
