Frequently Asked Questions
Q: What are the key dimensions and specifications for RA 631-031-004?
A: RA 631-031-004 features a 4 inch diameter, 2.88 inch tread width, and 3 inch hub length. It uses a 25 mm precision bearing bore with 95A polyurethane tread on cast iron core. The wheel assembly includes sealed bearings compatible with standard Raymond reach truck axle configurations.
Q: Which Raymond electric lift truck models is RA 631-031-004 designed for?
A: RA 631-031-004 is compatible with Raymond 7200, 7300, 7400, 7500, and 7600 Reach-Fork trucks as well as RRS and RSS Walkie Reach models. Confirm your equipment model designation and serial range align with supported versions before ordering to ensure fitment.
Q: What extensive cross-reference part numbers are available for RA 631-031-004?
A: RA 631-031-004 replaces 631-031, 631-030, 631-131, 631-131-03, 632-030, 632-030-003, 632-031, 632-031-01, 630-050, 630-051, 031-042-310, 030-032-310, 723-009, RY-641, and S641. It is equivalent to RA631-031-107 and 632-031-0 (and related variants). Verify exact fitment against your wheel core before cross-referencing.
Q: Why is the 25 mm precision bearing critical for RA 631-031-004 performance?
A: The 25 mm precision bearing bore provides accurate load distribution, reduces radial play and wobbling, and maintains wheel concentricity during high-speed reach truck operations. Precision fit bearings extend both bearing and tread life by minimizing lateral stress on the polyurethane compound and core assembly.
Q: How does the 95A polyurethane compound on RA 631-031-004 compare to softer or harder alternatives?
A: 95A polyurethane offers a balanced profile for general warehouse use: harder than 85A (less floor grip, longer tread life) and softer than 100A+ (better grip, lower lifespan). For standard indoor electric reach truck operations on concrete and sealed floors, 95A delivers optimal service life and load capacity without excessive tread wear.
