Frequently Asked Questions
Q: What are the dimensions and bearing specifications for the RA 631-051-001?
A: The RA 631-051-001 features a 5-inch diameter, 2.875-inch tread width, and 25 mm bore. It is equipped with 6205-2RS precision sealed bearings. These greaseless sealed bearings require no maintenance and provide extended service life in high-capacity material handling applications.
Q: Which Raymond equipment models are compatible with the RA 631-051-001?
A: The RA 631-051-001 is engineered for Raymond electric lift trucks, including 7200, 7300, 7400, 7500, 7600 Series Reach-Fork models and RRS/RSS Walkie Reach equipment. Verify your serial range against the equipment nameplate before ordering to confirm fitment.
Q: What polyurethane compound and hardness rating does this load wheel use?
A: The RA 631-051-001 uses a premium Durarun polyurethane tread with Shore A 95 hardness mounted on a cast iron hub. This compound formulation provides durability and traction in general material handling applications.
Q: What cross-reference and equivalent part numbers exist for the RA 631-051-001?
A: Direct equivalents include RA 631-051-001-A and RA 631-051-001-XL. Additional cross-references are 631-051-001 and 631051001. When ordering replacements, confirm the exact variant matches your equipment specifications.
Q: How long does the polyurethane tread last under normal operation?
A: Tread life varies with load, floor conditions, and duty cycle. The premium Durarun 95A compound is formulated for extended service life in demanding warehouse and production environments. Monitor tread wear visually and replace when wear approaches the bearing seat to prevent bearing damage.
Q: What maintenance is required for the sealed bearings?
A: The 6205-2RS sealed bearings are greaseless and require no lubrication. Inspect for smooth rotation during equipment operation. If bearings develop noise or roughness, replace the wheel assembly.
