Frequently Asked Questions
Q: What are the CT 1201770 wheel dimensions?
A: The CT 1201770 has a 200 mm diameter, 50 mm width, and 20 mm bore. These dimensions are critical for fitment on Caterpillar electric lift trucks and pallet jacks. Verify your axle diameter and hub spacing before ordering.
Q: Are there cross-reference part numbers for the CT 1201770?
A: Yes. The CT 1201770 has the following cross-references: CT 1201770-A and CT 1201770-XL. These variants have different specifications and are not interchangeable. Confirm your equipment serial number and model to order the correct variant.
Q: What is the bore size and axle compatibility?
A: The 20 mm bore matches standard 20 mm axle shafts on Caterpillar electric lift trucks. The 20 mm bore is also compatible with 20 mm bearing systems used on most electric warehouse equipment. Do not force a wheel onto an axle of different diameter.
Q: What polyurethane hardness rating does the CT 1201770 have?
A: The CT 1201770 has a 95A hardness polyurethane tread. This moderate hardness provides good wear resistance for electric lift trucks on indoor warehouse floors. The tread compound is optimized for dry concrete and smooth epoxy surfaces.
Q: What is the hub material for the CT 1201770?
A: The hub is constructed from machined steel core with integral bearing surfaces. The polyurethane tread is bonded to this machined steel core. Machining ensures precise bore dimensions for consistent axle fitment.
