GW L19

Frequently Asked Questions

Q: What is the GW L19 and which manual pallet jacks does it fit?
A: The GW L19 is a replacement load roller assembly constructed from black UL compound material, designed for manual pallet jack applications. It is used as both an OEM and aftermarket replacement part where GW L19 specifications are required. No cross-reference part numbers have been documented. Verify your jack manufacturer and model before ordering to confirm GW L19 compatibility.

Q: What surface finish does the GW L19 have and why does it matter?
A: The GW L19 features a precision-machined surface finish. This machining reduces friction during load transfer and provides consistent contact with the load platform. A precision finish extends roller life under repeated use and prevents uneven wear that can cause tracking misalignment.

Q: Can I substitute the GW L19 with a polyurethane roller like the GW L20?
A: No. The GW L19 uses black UL compound material while the GW L20 uses polyurethane. These have different load ratings, rolling resistance, and floor-marking characteristics. UL compound provides higher durability in heavy-duty applications. Do not mix roller types on the same jack. Always replace with the exact part number specified in your equipment documentation.

Q: How do I know when the GW L19 needs replacement?
A: Replace the GW L19 if you observe flat spots or visible wear on the machined surface, increased resistance when pushing the jack, or uneven wear patterns. If the load does not sit level on the platform or the jack pulls to one side, one or more rollers may be worn. Inspect all load rollers together; if one is worn, replace all rollers as a set to maintain balanced load distribution.

Q: What tools and steps are needed to replace the GW L19?
A: Replacement requires removing the load platform or frame fasteners to access the roller assembly mounting points. You will need standard wrenches or sockets matching your jack hardware. Remove the old roller and inspect the mounting bracket for damage or corrosion. Install the new GW L19 using the same fastening pattern, ensuring the roller rotates freely and is centered in the bracket. Do not over-tighten fasteners, which can bind the roller. Test operation under light load before full use.

Q: How often should the GW L19 be maintained?
A: Inspect load rollers monthly during regular equipment maintenance. Clean the machined surface to remove dirt and debris that increases rolling resistance. If your jack operates in wet environments, dry the roller after exposure to prevent corrosion. UL compound rollers typically last 18-36 months under normal warehouse use. Lifespan decreases with heavier loads, rough flooring, or frequent use. Replace if wear becomes visible or performance degrades.
