Frequently Asked Questions
Q: What is the difference between CT 1201770 and CT 1201770-XL?
A: The CT 1201770-XL is an oversized variant with a larger diameter (3.5 inches versus 200 mm on the standard CT 1201770). The XL also uses a higher hardness polyurethane (97A versus 95A). These wheels are not interchangeable; confirm your equipment model before ordering.
Q: What diameter does the CT 1201770-XL have?
A: The CT 1201770-XL has a 3.5 inch diameter. The larger diameter provides reduced rolling resistance and is suited for specific Caterpillar electric lift truck models. Do not install on equipment designed for 200 mm wheels; fitment will fail.
Q: What is the polyurethane hardness for the XL version?
A: The CT 1201770-XL uses 97A hardness polyurethane. This higher hardness provides increased wear resistance and is optimized for heavier duty or more aggressive warehouse environments. The increased hardness may result in slightly reduced traction on slippery floors.
Q: What is the bore size for the CT 1201770-XL?
A: The CT 1201770-XL has a 20 mm bore. This matches standard 20 mm axle shafts on compatible Caterpillar electric lift truck models. The 20 mm bore is not adjustable; do not attempt to modify for different axle sizes.
Q: What is the core material of the CT 1201770-XL?
A: The CT 1201770-XL has a steel core with machined polyurethane tread finish. The steel core provides structural support for the larger diameter and higher hardness requirements. The machined outer surface ensures consistent wheel geometry and axle fitment.
