Frequently Asked Questions
Q: What are the specifications of the CR 83970 polyurethane load wheel?
A: The CR 83970 features a 3.25 inch diameter polyurethane tread with 95 Shore A hardness, 4.50 inch width, and a 0.75 inch bore diameter. It is rated for 3000 lbs load capacity and uses ball bearing press-fit mounting for Crown GPW Series electric pallet trucks.
Q: Which Crown pallet jack models does the CR 83970 fit?
A: The CR 83970 is designed for Crown GPW Series electric pallet trucks. Cross-reference part numbers include CR 83970-A, CR 83970-010-A, CR83970-050, and equivalent number GPW83970. Always verify your equipment model before ordering.
Q: What advantages does polyurethane tread offer over steel?
A: Polyurethane tread provides superior traction on wet floors and cold storage environments. The 95 Shore A hardness rating offers good wear resistance while maintaining grip. Polyurethane wheels reduce noise and vibration compared to steel wheels.
Q: How does the CR 83970 differ from the CR 83970-010?
A: The CR 83970 has a 0.75 inch bore diameter and 4.50 inch width, while the CR 83970-010 uses a 30mm bore and 4.25 inch width. Bore diameter and width are critical for fitment. Verify your equipment specifications before substituting.
Q: What maintenance does the CR 83970 require?
A: Inspect bearing seals regularly for contamination. Clean polyurethane tread periodically to maintain traction. Check wheel mounting and ball bearings for excessive play or noise. Replace when tread wear exceeds 25 percent or bearing noise develops.
Q: What is the expected lifespan of the CR 83970?
A: With standard warehouse use on typical floors, expect 3-5 years of service life. Lifespan varies based on load intensity, floor surface, and environmental conditions. Heavy use or rough floors will reduce service life.
