GW 9135-AL-A

Frequently Asked Questions

Q: What parts does GW 9135-AL-A cross-reference with?
A: The GW 9135-AL-A is equivalent to GW9135, 9135, GW 9135-AL, and GW 9135-A (according to the spec sheet). The -A suffix indicates this is the primary part number. When searching inventory systems, use all variants as suppliers may list stock under any of these numbers. The part is the same regardless of which number is printed on the box. Order confirmation should match your truck specifications, not just the part number format.

Q: Is the GW 9135-AL-A suitable for heavy-duty or light-duty applications?
A: The GW 9135-AL-A with 95A Shore hardness is rated for general-duty electric lift truck applications, typically 2500-4000 lb capacity jacks. For heavy-duty environments (5000+ lb trucks, constant use, rough floor surfaces), the harder 97A variant (GW 9135-XL) is more appropriate. In light-duty warehouses with smooth floors and intermittent use, the 95A assembly will last 3-4 years. In heavy industrial settings, expect 18-24 months before tread degradation. Choose based on your actual load and duty cycle, not truck nameplate alone.

Q: What should I check before installing the GW 9135-AL-A to ensure compatibility?
A: Before installation verify: (1) Axle diameter matches bearing ID (usually 17mm or 20mm for this assembly - check your truck specs). (2) Mounting space accommodates the wheel width (typically 4.5-5 inches depending on variant). (3) Wheel diameter 3.25 inches fits between frame rails or guards. (4) Existing wheel is mounted with a snap ring (vs. bolt-on style). (5) Truck is on level ground and can be safely lifted. If any dimension does not match, do not force installation. Contact the supplier or OEM for the correct assembly model.

Q: How long does the GW 9135-AL-A typically last in a pallet jack?
A: In typical warehouse conditions (8 hour shifts, 50-70 percent average load, indoor smooth concrete), the GW 9135-AL-A lasts 24-36 months before performance degrades. Lifespan varies with: (1) Load consistency (steady heavy loads shorten life). (2) Floor type (smooth concrete extends life; rough, oily, or salted floors reduce life). (3) Storage (outdoor or hot storage reduces lifespan). (4) Bearing maintenance (sealed bearings require no service, but corrosion from moisture can cause premature failure). Inspect every 6 months and replace if tread shows cracking, flat-spotting, or if bearing resistance increases.

Q: What does it mean that the GW 9135-AL-A includes installed bearings?
A: The assembly comes fully assembled with the bearing cartridge already pressed into the hub. You do not need to source, press, or install bearings separately. This simplifies ordering and installation. However, it also means you cannot upgrade to a different bearing type (e.g., if you wanted a grease-able bearing instead of sealed). The factory bearing is sealed for low maintenance but is not user-serviceable. Order the -A assembly when you want a ready-to-install solution.

Q: If the GW 9135-AL-A bearing starts to squeak, can it be repaired or must I replace the whole wheel?
A: Squeaking in a sealed bearing cartridge indicates internal corrosion or seal failure. The bearing is not serviceable and cannot be disassembled for cleaning or re-lubrication. You must replace the entire wheel assembly. Attempting to drill a grease fitting or open the seal will destroy the bearing. The cost of a new assembly (typically 40-80 dollars) is far less than labor to disassemble and re-seal a bearing. Replace immediately to prevent wheel lockup, which can damage your lift truck.
