A 4-inch red single ball bearing caster with a double brake is a heavy-duty wheel designed to make equipment both highly mobile and securely stationary when needed . Its features work together to provide smooth movement, precise control, and safe locking for various applications.
4-Inch Diameter Wheel: This size offers a versatile balance between maneuverability and load capacity. It's large enough to roll smoothly over slight unevenness in floors (like thresholds or small debris) while keeping the equipment's deck height low.
Red Color (Polyurethane Material): The red color typically indicates the wheel is made of polyurethane. This material is chosen for its functional benefits: it is non-marking (won't leave scuff marks on floors), protects floor surfaces, operates quietly, and absorbs vibration for a smoother ride.
Single Ball Bearing: This refers to the bearing in the swivel head (the raceway that allows the wheel to rotate 360°). A single ball bearing raceway allows for smooth swiveling and steering, making it easy to change directions, even under load. For heavier applications, a double ball bearing raceway is also common.
Double Brake (Total Lock): This is the most significant safety and control feature. A "double brake" means a single pedal simultaneously locks two things:
The Wheel: Prevents the wheel from rolling.
The Swivel: Prevents the caster from pivoting or turning, locking it in a fixed forward position.
Functional Purpose and Applications
The combination of these features makes this caster ideal for tasks requiring precise positioning and stability.
Application Scenarios:
Medical and Hospital Equipment: For heavy machines like hospital beds, stretchers, or surgical lights that must remain perfectly still during a procedure .
Industrial Carts and Dollies: For carts carrying delicate components or tools that need to stay put on a slightly sloped factory floor .
Commercial Platforms: For scissor lifts, scaffolding, or staging platforms where worker safety depends on the equipment not moving unexpectedly .
A/V and Studio Equipment: For heavy speaker cabinets or lighting racks that need to be precisely positioned and then locked down to prevent unwanted movement.
Common Specifications:
Mounting: Typically features a top plate with pre-drilled holes for easy bolting onto equipment .
Load Capacity: Varies by specific model and construction, but can range from 300 lbs to over 1,200 lbs per caster
