Frequently Asked Questions
Q: What is the difference between GW L16 and GW L15, and can I mix them on the same jack?
A: Both GW L16 and GW L15 are black ultra-poly load wheels with identical dimensions (2.75 inches diameter, 3.75 inches width) and the same 6204-2RS-3/4 bearing. The product data suggests they are functionally equivalent or the same part under different SKUs. Mixing them on one jack is safe and will not cause problems, but for consistency and warranty tracking, install the same SKU on all four positions if possible.
Q: How often should I inspect or maintain GW L16 wheels?
A: Inspect GW L16 wheels monthly if the jack is in daily use: (1) Check for visible tread wear, cracks, or chunks missing from the polyurethane. (2) Spin each wheel and listen for grinding or squeaking noises indicating bearing issues. (3) Look for debris wrapped around the axle or caught in the wheel rim. (4) Verify the jack moves smoothly when loaded. If tread wear exceeds 20 percent of original thickness or bearings sound rough, replace the wheel assembly.
Q: GW L16 is black ultra-poly. Does the black color indicate different material properties than natural or gray poly?
A: Black color typically comes from carbon additives or pigments in the polyurethane formulation. These can provide UV resistance and sometimes slightly improved wear properties, but the black color alone does not guarantee harder material. GW L16 specs do not list Shore A hardness, so you cannot directly compare it to products that do state hardness. Contact the supplier for Shore A data if durability comparison is critical to your application.
Q: Can GW L16 be used as a replacement if my jack manual specifies a different part number?
A: Do not assume GW L16 is equivalent without verification. If your jack manual specifies a different part number, contact your supplier or the jack OEM to confirm GW L16 compatibility. Installing wrong wheel sizes or bore diameters can cause binding, tracking problems, or unsafe jack operation. Cross-reference must be confirmed before purchase and installation.
Q: What is the cost difference between GW L16 and competing equivalent wheels, and is it worth upgrading?
A: Pricing and cross-reference data are not provided in the product specifications. Contact your supplier for cost comparison with alternative brands like Yale, Hyster, or Generic equivalents. Upgrade decisions should be based on current wheel condition, floor type, and expected usage frequency, not price alone. A worn wheel set can be replaced for the cost of a single wheel assembly.
