Frequently Asked Questions
Q: What is the difference between the CT 971757-XL-A and CT 971757-XL?
A: The CT 971757-XL-A is a complete assembly that includes sealed ball bearings pre-installed on the axle, whereas the CT 971757-XL is the wheel only. If your equipment needs the wheel and bearing together as a unit, the -A assembly is ready to integrate. Both use identical polyurethane wheels with 97A Shore durometer hardness and specifications.
Q: What equipment models are compatible with this load wheel assembly?
A: This load wheel is designed for electric material handling equipment requiring sealed bearing wheel assemblies. Compatibility depends on matching your equipment's axle bore diameter, wheel carriage width, and load capacity rating. Before ordering, verify the current wheel diameter, bore size, and carriage specifications on your equipment to ensure proper fit.
Q: What bearing type is included with this assembly?
A: The assembly includes sealed ball bearings rated for material handling equipment loads. Sealed bearings keep dirt and moisture out, extending bearing life in warehouse and dock environments. The ball bearing design reduces friction and supports smooth wheel rotation even under continuous duty electric lift truck operation.
Q: What core material is used and how durable is it?
A: The wheel features a high-strength steel core that is precision-machined to ensure bore accuracy and runout tolerances. High-strength steel resists permanent deformation under the continuous load cycles of electric material handling equipment and provides a stable bearing mount surface. The core prevents flex or play that would accelerate bearing wear.
Q: How long do sealed bearings typically last?
A: Sealed bearing lifespan is typically 3-5 years in continuous warehouse duty, though heavy loads or contaminated floors may shorten this. The sealed design slows bearing degradation compared to open bearings. When bearings wear, you will notice increased wheel drag, noise, or wobble. At that point, the entire assembly should be replaced.
Q: Why is 97A Shore durometer polyurethane important?
A: The 97A Shore durometer polyurethane tread provides excellent wear resistance and load capacity for electric material handling applications. This hardness resists tread degradation from abrasion and maintains grip on clean, dry concrete floors. The harder compound also reduces rolling resistance compared to softer wheels, beneficial for battery-powered equipment efficiency.
Q: How do I verify compatibility before ordering?
A: Measure your current wheel's outer diameter, axle bore diameter, and the distance between mounting flanges on your equipment carriage. Compare these dimensions to the specification data for the CT 971757-XL-A. If dimensions match, the assembly should be compatible. When in doubt, contact your equipment manufacturer or a parts specialist.
