GW 133

Frequently Asked Questions

Q: What are the cross-reference and equivalent part numbers for the GW 133?
A: The GW 133 is cross-referenced as GP 133 and GP133 from certain aftermarket manufacturers. These part numbers are equivalent and provide the same specifications: 3.000 inch diameter, 3.700 inch width, 0.75 inch bearing ID, and polyurethane tread. When ordering, confirm the supplier stocks the exact cross-reference you need. Do not assume GP 133 from all suppliers is identical, verify dimensions and bearing ID before purchase.

Q: Is the GW 133 suitable for replacement at the fork tip of a manual pallet jack?
A: Yes. The GW 133 is specifically designed as a fork tip load wheel replacement for standard manual pallet trucks. The 3.000 inch diameter and 3.700 inch width are common fork tip wheel specifications. The pre-installed bearings allow quick and easy replacement without additional bearing installation steps. Confirm your jack has a 0.75 inch ID axle bore before installing. If your jack axle bore is 20mm ID, the GW 133 will not fit.

Q: Can I replace just the fork tip wheels and keep the other wheels unchanged?
A: Yes, you can replace fork tip wheels separately if they are the same model number as the other wheels. However, it is best practice to replace all four wheels as a set to ensure even load distribution and consistent wear. If fork tip wheels (GW 133) wear faster than other wheels, it may indicate improper load centering or fork alignment issues. Investigate the cause before replacing wheels. Mixing wheel models with different bearing IDs is not recommended.

Q: What does pre-installed bearings mean and does it affect installation?
A: Pre-installed bearings means the sealed ball bearings are already pressed into the wheel hub. You do not need to disassemble or install bearings separately. Simply slide the complete wheel assembly onto the axle shaft and secure with the axle bolt and cotter pin. This reduces installation time and eliminates the need for bearing pressing tools. Verify the bearing bore (0.75 inch ID) aligns with your axle shaft before sliding the wheel onto the axle.

Q: What is the load capacity and typical service life of the GW 133?
A: The GW 133 polyurethane tread is rated for manual pallet jacks with capacities up to 5000 lbs. Actual wheel load depends on jack rated capacity and load placement. Sealed bearings extend service life to 3-7 years with proper use and regular inspection. Fork tip wheels may wear faster due to higher stress during lifting and tilting. Replace immediately if tread shows separation, cracking, or flat spotting. Inspect wheels every month to monitor tread condition.

Q: What maintenance is required for the GW 133 wheel assembly?
A: Inspect wheels monthly for debris lodged in the tread and remove by hand or with a brush. Wipe clean with a damp cloth. The sealed bearings require no greasing or lubrication. If wheels develop a squeak or resistance during rotation, the bearings may be losing their seal. At this point, you can replace individual wheels or the entire set. Do not attempt to re-seal or re-grease sealed bearings. Operate within jack load rating and avoid dropping loads, which can damage wheels and bearings.
