Frequently Asked Questions
Q: What is the difference between GWK-LCM-LW and GWK-LCMP-LW, and which should I choose?
A: The GWK-LCM-LW uses uncoated steel rollers suitable for factory and outdoor concrete. The GWK-LCMP-LW uses black ultra-polyurethane 70D rollers that resist corrosion, do not rust, and perform better on polished or sealed warehouse floors. Both are compatible with LCM50 and LCM4W models. Choose steel (GWK-LCM-LW) for rough factory use; choose ultra-poly (GWK-LCMP-LW) for food plants, pharmaceutical warehouses, cold storage, and showroom environments where rust staining is unacceptable.
Q: Are the 70D ultra-polyurethane rollers on the GWK-LCMP-LW suitable for all floor types?
A: The 70D durometer is optimized for smooth indoor warehouse floors, sealed concrete, and epoxy surfaces. It provides good grip on most materials but may slip on oil-covered or heavily waxed floors. On rough outdoor concrete or uneven factory floors, the softer poly material can wear faster than 92A harder compounds. For rough outdoor use, choose the GWK-LCM-LW steel kit instead. Always verify your floor type before ordering.
Q: Is the GWK-LCMP-LW a direct replacement on my Lift-Rite LCM4W jack, or does it require adaptation?
A: The GWK-LCMP-LW is a plug-and-play replacement for both LCM50 and LCM4W models; no adaptation is required. The axle diameter and bearing cavity dimensions are identical across both models. Fasteners are included. The LCM4W uses a four-wheel design (two load wheels and two steer wheels), but the kit replaces only the load wheel pair. Confirm your jack model by checking the nameplate on the pump assembly before ordering.
Q: How much longer does the ultra-polyurethane material last compared to steel in a cold storage environment?
A: In freezing or near-freezing cold storage, the GWK-LCMP-LW ultra-poly rollers typically last 20-30 months versus 12-18 months for uncoated steel. Steel becomes brittle in extreme cold and can crack if struck; polyurethane remains flexible. Additionally, ice does not adhere to polyurethane as readily as to steel. However, frequent temperature cycling (ambient to freezer and back) can degrade polyurethane faster than constant cold. Inspect rollers every three months in cyclic environments.
Q: What bearing material is used in the GWK-LCMP-LW, and are they sealed against food plant washdown procedures?
A: The GWK-LCMP-LW uses chrome steel sealed ball bearings with rubber or plastic seals rated for washdown resistance. They are NOT immersion-rated or food-grade certified. In food plants, keep the jack away from direct spray; wipe down after washdown and allow to air dry before next use. Do not submerge the wheel assemblies. If your facility requires full IP67 or food-service certification, consult your parts supplier for specialized sealed bearing options.
