Frequently Asked Questions
Q: What are the complete specifications for the RA 640-070-003-A load wheel assembly?
A: The RA 640-070-003-A features a 5.000 inch outer diameter with 2.875 inch width, 95A durometer polyurethane tread bonded to cast iron core, factory-installed 6205-2RS precision ball bearings, and a 25mm inner diameter bore. This assembly is designed for vibration-minimized operation on Raymond 020 and 031 Series Reach Trucks.
Q: Which Raymond reach truck models are compatible with the RA 640-070-003-A?
A: The RA 640-070-003-A is engineered for Raymond 020 and 031 Series Reach Truck applications with 2.047 inch bore specification. Verify your equipment model and bore diameter match before ordering to ensure proper fit and performance.
Q: What bearing type is factory-installed in the RA 640-070-003-A?
A: The RA 640-070-003-A comes with 6205-2RS precision ball bearings pre-installed. The 2RS designation indicates sealed bearings with rubber protection on both sides. These bearings are designed for 25mm bore diameter and provide maintenance-free operation under normal conditions.
Q: What alternate or cross-reference part numbers apply to the RA 640-070-003-A?
A: The RA 640-070-003-A has an alternate part number RA 640-070-003 and supersedes RA 640-070-002-A. Related Raymond part numbers include 630-050, 630-051, 632-031, and 633-031. Verify the exact part number on your equipment before placing an order.
Q: How does the smooth tread profile improve reach truck performance?
A: The smooth tread profile reduces vibration and provides consistent rolling resistance across concrete and asphalt warehouse floors. This design enhances steering precision and reduces operator fatigue on Raymond 020 and 031 Series reach trucks during extended picking operations.
Q: What is the expected maintenance schedule for the RA 640-070-003-A?
A: Monitor tread wear during monthly equipment inspections. The sealed 6205-2RS bearings require no lubrication or maintenance. Replace the assembly when polyurethane tread shows visible flatting, reduced traction, or the bearing develops noise during rotation. Expected service life depends on truck usage intensity and floor conditions.
