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.
