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.
Key Features and Their Functions
-
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.
