Frequently Asked Questions
Q: What is the rated load capacity of the CA 09-PU-507-S-ST1?
A: The CA 09-PU-507-S-ST1 has a 300 lb rated load capacity with a 1.0 service factor. This is the safe working load per caster. Multiply by the number of casters on your cart to determine total cart capacity. Do not exceed rated limits.
Q: Why does the CA 09-PU-507-S-ST1 use stainless steel bearings?
A: Stainless steel ball bearings resist corrosion and moisture degradation better than standard steel. The CA 09-PU-507-S-ST1 is suitable for cooler environments, damp storage areas, or facilities where stainless steel bearing durability is required. This design extends bearing life in challenging conditions.
Q: Is the CA 09-PU-507-S-ST1 safe for wet floors or cold storage?
A: The thermoplastic rubber tread on the CA 09-PU-507-S-ST1 provides fair grip on wet floors. The stainless steel bearings resist moisture. However, the non-marking tread is designed for hard, dry floors. For heavy-duty wet storage or consistently cold environments, verify floor traction with a test unit first.
Q: What does non-marking tread mean on the CA 09-PU-507-S-ST1?
A: Non-marking tread does not leave dark scuff marks or residue on floors, making it suitable for clean rooms, showrooms, or facilities where floor appearance matters. The thermoplastic rubber composition is engineered to minimize staining while maintaining rolling capability.
Q: How does the double ball raceway swivel differ from standard swivel designs?
A: The double ball raceway swivel on the CA 09-PU-507-S-ST1 distributes radial and thrust loads across two separate bearing rows, reducing friction and extending service life. This design allows smooth 360 degree rotation and supports heavier cart maneuvering compared to single-bearing swivels.
