Frequently Asked Questions
Q: What are the exact dimensions of the CT 1201778 load wheel?
A: The CT 1201778 has a 3.25-inch outer diameter, 4.88-inch width, and 20 mm bore. These dimensions are critical for axle fitment and wheel track alignment on Caterpillar electric pallet trucks. Always verify your equipment bore size and wheel pocket width before ordering.
Q: What is the core material and why does it matter?
A: The CT 1201778 features a glass-reinforced nylon core bonded with polyurethane tread. Glass-reinforced nylon is lighter than solid steel, provides sufficient rigidity for pallet jack applications, and resists corrosion. This combination reduces weight while maintaining load-bearing strength.
Q: Is the CT 1201778 compatible with Caterpillar electric pallet trucks only?
A: The CT 1201778 is designed for Caterpillar electric pallet jacks and lift trucks equipped with 20 mm axle bores and 4.88-inch wheel pockets. Cross-reference your equipment documentation to confirm compatibility with your specific Caterpillar model and serial range.
Q: What bearing configuration does this wheel use?
A: The CT 1201778 is equipped with a sealed ball bearing that is press-fit mounted onto the axle. The sealed design excludes dirt, moisture, and debris, minimizing maintenance requirements and extending bearing life under typical warehouse conditions.
Q: How does polyurethane tread compare to rubber for load wheel applications?
A: Polyurethane provides superior abrasion resistance, longer wear life, and better performance across temperature variations compared to rubber. For electric pallet trucks, polyurethane tread resists tears from rough floors and maintains grip consistency as the wheel wears.
Q: What floor conditions is the CT 1201778 rated for?
A: The CT 1201778 is rated for standard indoor concrete and polished floors typical of warehouses and distribution centers. Performance on wet or heavily contaminated floors should be evaluated based on your specific facility conditions.
