Frequently Asked Questions
Q: What are the specifications for the RA 631-051-001-A load wheel assembly?
A: The RA 631-051-001-A is a complete load wheel assembly with a 5.000 inch outer diameter, 2.875 inch tread width, 25mm bore, and 6205-2RS greaseless sealed bearings. The assembly features 95A durometer polyurethane tread on a cast iron core with hardened bearing seat material.
Q: Which Raymond models use the RA 631-051-001-A wheel?
A: This wheel assembly is engineered for Raymond 7200-7600 Series Reach-Fork Trucks and RRS/RSS Walkie Reach equipment. Check your equipment model and serial range on the nameplate to confirm compatibility before purchase.
Q: What polyurethane grade is used on the RA 631-051-001-A?
A: The RA 631-051-001-A features Durarun polyurethane with Shore D 95A hardness. This premium domestic polyurethane compound is designed for extended service life in demanding material handling applications on concrete and asphalt floors.
Q: Is the RA 631-051-001-A directly interchangeable with other RA 631-051-001 variants?
A: The -A variant has specific dimensional and bearing specifications. While it is cross-referenced with related RA 631-051 variants, verify your equipment bore size and diameter requirements match before substituting parts.
Q: What factors affect the service life of the polyurethane tread?
A: Tread life depends on load capacity utilization, floor surface type, temperature, and duty cycle frequency. The 95A compound provides good wear resistance on both dry and slightly damp concrete floors. Replace wheels when tread wear becomes uneven or approaches the bearing seat.
Q: Are the 6205-2RS bearings rebuildable or must the entire assembly be replaced?
A: The 6205-2RS bearings are sealed units and cannot be serviced. If bearings fail, replace the entire wheel assembly. Sealed bearings cannot be repacked or rebuilt as this compromises their protection and performance.
