Frequently Asked Questions
Q: What is the CA 11-MP-423-S caster assembly?
A: The CA 11-MP-423-S is a swivel caster assembly with a 4 inch diameter mold-on polyurethane wheel for 11 Series stocking carts. Polyurethane wheels offer good traction, quieter operation, and shock absorption.
Q: What are the key specifications of the CA 11-MP-423-S?
A: The CA 11-MP-423-S features a 4 inch polyurethane wheel with a pressed steel frame. The mold-on design means the polyurethane is bonded directly to the steel core. It is designed as a swivel caster for 360-degree rotation and maneuverability.
Q: What is the difference between 4 inch and 6 inch wheels on polyurethane casters?
A: The 4 inch wheel on the CA 11-MP-423-S is smaller and lighter-duty than 6 inch alternatives. Use 4 inch wheels for lighter loads and lower-profile carts. Larger wheels roll easier over obstacles and uneven floors. Confirm your cart frame specification before ordering.
Q: Why choose mold-on polyurethane over cast iron or separate wheel designs?
A: Mold-on polyurethane provides quieter operation, better floor grip, and shock absorption compared to cast iron. The bonded design eliminates the need for separate wheel replacement and reduces assembly complexity. It is ideal for clean environments and smooth indoor floors.
Q: How should the CA 11-MP-423-S be maintained?
A: Clean the polyurethane wheel regularly to remove dust and residue that reduces traction. Inspect for cuts, gouges, or delamination of the polyurethane from the core. Lubricate the swivel bearing according to manufacturer guidelines. Do not use harsh solvents that degrade polyurethane.
Q: What is the expected lifespan of the CA 11-MP-423-S?
A: Mold-on polyurethane casters typically last 2 to 4 years depending on load, frequency of use, and floor surface. Continuous use in heavy-duty environments or exposure to oils and solvents shortens lifespan. Replace if polyurethane tears, peels, or the wheel develops a flat spot.
