Frequently Asked Questions
Q: What is the shaft diameter specification for the VJ 55F7 retaining ring?
A: The VJ 55F7 retaining ring is engineered for a 0.875 inch shaft diameter. Verify your pallet jack shaft dimension matches this specification before ordering to ensure proper fit and retention.
Q: What material and finish does the VJ 55F7 use?
A: The VJ 55F7 is manufactured from SAE J403 spring steel with a phosphate finish. The steel grade is SAE 1060-1095 spring steel with a minimum Rockwell C45 hardness. The phosphate coating provides corrosion resistance and a secure grip on the shaft.
Q: Which Valu-Jack pallet jack models use the VJ 55F7?
A: The VJ 55F7 retaining ring is compatible with Valu-Jack model 5500-2 manual pallet jacks and alternate model designations 55002 Hydraulic Unit and 5500 2 Hydraulic Unit. Confirm your pallet jack model before ordering.
Q: What is the retention function of the VJ 55F7 in the hydraulic assembly?
A: The VJ 55F7 retaining ring secures components onto the shaft and prevents axial movement during lift and lower cycles. The spring steel design maintains tension under load while the phosphate finish resists wear and corrosion.
Q: Are there OEM alternatives to the VJ 55F7?
A: The VJ 55F7 is the OEM retaining ring for Valu-Jack 5500-2 hydraulic assemblies. No cross-reference equivalents from competing manufacturers have been documented. For alternative options or special applications, contact our parts specialists.
Q: How does the phosphate finish on the VJ 55F7 affect durability?
A: The phosphate finish increases the service life of the VJ 55F7 by protecting against corrosion, especially in humid or outdoor storage environments. The coating also improves grip security on the shaft, reducing slip and maintaining retention integrity across repeated duty cycles.
