Gray Industrial Cart Casters 4 Inch Swivel Casters With Brake
Features and Functional Purpose
| Feature | Functional Purpose |
|---|---|
| 4" Gray Polyurethane (PU) Wheel | The gray color typically indicates a Polyurethane (PU)wheel. Its primary purpose is to provide a tough, wear-resistant, and shock-absorbing rolling surface. PU wheels offer high load capacity, are non-marking, protect floors, and operate more quietly than hard plastic or steel wheels . |
| Double Ball Bearings | The caster features double ball bearings in the wheel hub. This ensures the wheel rolls smoothly and effortlessly even under load, reducing the pushing force required and providing superior maneuverability compared to plain bore or single bearing casters . |
| 360-Degree Swivel Design | The mounting plate and swivel raceway allow the caster to rotate a full 360 degrees. This provides maximum flexibility and directional control, enabling equipment to be easily steered and repositioned in tight spaces . |
| Heavy-Duty Steel Bracket | The frame is constructed from high-quality steel with a protective finish (often zinc-plated or galvanized). This provides exceptional durability and corrosion resistance, ensuring long-lasting performance in demanding environments . |
| Gray Color | The neutral gray color offers a professional and versatile appearance that blends well with most industrial and commercial equipment without showing dirt as easily as white wheels . |
Summary of Functional Benefits
-
High Load Capacity: 4-inch PU wheels typically support 200-400 lbs per caster, making them suitable for medium to heavy-duty equipment and machinery .
-
Smooth & Effortless Maneuverability: The double ball bearing design allows for easy rolling and instant directional changes, even with heavy loads. This reduces operator fatigue and improves efficiency when moving equipment .
-
Floor Protection & Quiet Operation: PU is non-marking and absorbs shock, ensuring the casters will not damage or leave scuff marks on floors while moving quietly . This makes them ideal for use on hardwood, tile, epoxy, and vinyl surfaces .
-
Durable & Long-Lasting: PU wheels resist abrasion, cutting, and tearing, offering longer service life than rubber or plastic wheels in demanding applications . They also resist many chemicals, oils, and cleaning agents .
-
Corrosion-Resistant Construction: The steel bracket with protective coating resists rust and deterioration, ensuring reliable performance even in workshops, factories, or environments with moisture exposure .
-
Versatile Appearance: The neutral gray color complements a wide range of equipment styles and hides dirt better than lighter colors, maintaining a professional appearance longer .
