Frequently Asked Questions
Q: What is the difference between GW 9143-SG and GW 9143-SG-A?
A: GW 9143-SG is the wheel only. GW 9143-SG-A is the complete caster assembly with the bearing already installed and sealed. GW 9143-SG-A is ready for direct mounting. If your jack uses quick-change wheel kits, order GW 9143-SG-A for faster replacement.
Q: Is GW 9143-SG-A compatible with my electric pallet jack?
A: GW 9143-SG-A fits electric pallet jacks and lift trucks using 4.000 inch diameter x 2.880 inch width caster wheels with a 95A Shore A durometer rating. Confirm your equipment uses this wheel size before ordering. Check the bearing ID on your jack housing to ensure compatibility with standard bore specifications.
Q: Can I swap GW 9143-SG-A onto another brand of electric jack?
A: GW 9143-SG-A may work on competitor equipment if the mounting interfaces match. Many jacks use standard 4-inch wheel sizes. Cross-reference the wheel size and bearing bore on your equipment before purchasing. Failure to verify compatibility results in wasted parts and downtime.
Q: How do I install GW 9143-SG-A on my electric jack?
A: GW 9143-SG-A includes pre-installed bearings and is ready to mount. Remove the old wheel assembly by unbolting or using your jacks quick-release mechanism. Slide the new assembly onto the axle or mounting post and secure with bolts or clips. Do not force the wheel onto the axle; it should slide smoothly. Tighten fasteners firmly to prevent rotation.
Q: What maintenance does GW 9143-SG-A require?
A: Inspect bearings monthly for smooth rotation. The assembly is sealed, so no lubrication is required. If the wheel becomes hard to rotate or makes grinding sounds, the bearing needs replacement. Do not attempt to lubricate sealed bearings. Replace the entire assembly if bearing failure occurs.
Q: Can the bearing in GW 9143-SG-A be replaced separately?
A: The bearing is press-fitted into the GW 9143-SG-A assembly. Bearing replacement requires a bearing press and specialized tools. In most cases, it is more cost-effective to replace the entire GW 9143-SG-A assembly. Attempting to remove the bearing without proper equipment damages the wheel.
