Product Description

3 Inch Thermoplastic Rubber (TPR) Bolt Hole Caster Wheel With Double Brake

Feature Analysis and Functional Benefits

The core advantage of this caster lies in its dual-locking mechanism, floor protection, and ease of installation. Here is a breakdown of its key components:

Feature Category	Specifics	Function & Benefits
Wheel Material (TPR)	The tread is made of Thermoplastic Rubber (TPR), typically bonded to a Polypropylene (PP) core.	① Floor Protection: TPR is non-marking and gentle on floors, making it ideal for delicate surfaces like tiles, hardwood, and polished concrete. ② Quiet Operation: It effectively absorbs vibration and reduces noise, ensuring quiet movement of equipment—perfect for noise-sensitive environments. ③ Shock Absorption & Grip:Provides excellent traction and a smooth ride while cushioning the equipment from shocks and impacts during movement.
Brake System (Double Brake)	Refers to a "total lock" mechanism where a single pedal simultaneously locks the wheel rotation and the swivel movement of the rig.	① Absolute Stability: Unlike a single brake that only stops the wheel from turning, a double brake locks the swivel as well, preventing the equipment from moving, swiveling, or drifting. ② Enhanced Safety: This is critical for applications requiring precision or safety, such as medical procedures or stationary workstations, preventing any accidental movement.
Mounting Type (Bolt Hole)	The caster is mounted using a top plate with pre-drilled holes, secured with bolts.	① Secure Connection: Provides a more rigid and robust attachment compared to threaded stems, capable of handling higher loads and side thrusts. ② High Versatility: This is a standard mounting method compatible with the vast majority of equipment and carts that have flat mounting surfaces.
3-Inch Size & Build	The wheel diameter is 3 inches (approx. 75-76mm). Typical load capacity for this size ranges from 40kg to 80kg (90-175 lbs) per caster.	① Good Obstacle Clearance: The 3-inch size offers a balance between maneuverability and the ability to roll over small debris, door thresholds, or elevator gaps. ② Medium-Duty Load Capacity:Ideal for supporting medium-weight equipment without being too bulky or raising the equipment's center of gravity too high.

Ideal Applications

Given these features, this caster performs best in environments where quietness, floor care, and locking stability are top priorities:

Medical Industry: Hospital beds, medical carts, instrument stands. The double brake is essential for patient safety during transfers, and TPR ensures quiet movement in hallways and rooms.
Hospitality & Food Service: Service carts, room service tables, buffet stations. They allow staff to move equipment silently and smoothly in guest areas without damaging expensive flooring.
Office Environments: Mobile filing cabinets, AV carts, whiteboard stands, heavy office chairs. Enables quiet reconfiguration of spaces and protects office carpets or hard floors.
Light Industrial & Commercial: Tool carts, maintenance trolleys, retail display racks, platform trucks. Provides reliable mobility and the ability to lock the cart securely in one spot on the work floor.
Heavy-Duty Home Use: Plant pot holders (for large plants), BBQ grills, workbenches, homemade furniture. Makes it easy to move heavy items for cleaning or rearranging your space.
