75mm Thermoplastic Rubber (TPR) Gray Double Ball Bearings Swivel Caster For Equipment
| Category | Specification / Feature |
|---|---|
| Wheel Diameter | 75 mm (approx. 3 inches) |
| Wheel Material | Thermoplastic Rubber (TPR), Gray |
| Wheel Hardness | 65–85 Shore A (soft, resilient) |
| Caster Type | Swivel (360° rotation) |
| Bearings | Double ball bearings (wheel hub + swivel raceway) |
| Mounting | Various options: threaded stem, top plate, or hollow center (depending on model) |
| Load Capacity | Approx. 70–100 kg per caster (medium duty) |
| Floor Protection | Non-marking gray tread |
| Chemical Resistance | Good (resists water, mild acids, alkalis, alcohols) |
| Temperature Range | -50°C to +115°C |
| Environmental | Non-toxic, RoHS/PAHs compliant, recyclable |
| Brake Option | Double brake available (locks both wheel rolling and swivel mechanism) |
| Anti-static Option | Conductive TPR version available (ESD safe) |
Ultra-Silent Operation – TPR material reduces rolling noise by up to 40% compared to traditional rubber wheels. Ideal for noise-sensitive environments like hospitals, libraries, and offices.
Superior Floor Protection – TPR is non-marking and leaves no traces or scratches, protecting delicate surfaces such as epoxy flooring, tiles, and wood.
Excellent Shock Absorption – The soft, resilient nature of TPR (65–85 Shore A) provides cushioning and vibration damping, protecting sensitive equipment during movement.
Hydrolysis-Resistant – Unlike polyurethane (PU), TPR never hydrolyzes or delaminates, ensuring a long service life even in humid or wet conditions.
Effortless Maneuverability – Double ball bearings reduce rolling friction and swivel resistance, making heavy loads easy to move and turn in tight spaces.
High Load Capacity – Double ball bearings in the swivel raceway distribute loads evenly, providing superior weight-bearing performance compared to single-bearing designs. A single caster supports approximately 70–100 kg dynamically, with four casters supporting 280–400 kg.
Chemical & Environmental Resistance – TPR resists water, steam, mild chemicals, UV radiation, and ozone, making it suitable for indoor and outdoor use.
Low Maintenance – Sealed double ball bearings reduce dirt ingress, minimizing lubrication needs. TPR is easy to clean and does not absorb stains.
Safe & Eco-Friendly – TPR is non-toxic, odorless, and free of halogens and phthalates. It complies with RoHS and PAHs environmental standards and is recyclable.
| Application Area | Specific Use Examples |
|---|---|
| Medical & Healthcare | Hospital beds, medical instrument carts, infusion stands, dialysis carts, ultrasound equipment, ventilators, nursing carts, pharmaceutical carts |
| Laboratory & Cleanroom | Lab equipment stands, chemical trolleys, sterile workstations, cleanroom carts, electronics assembly stations |
| Food Service & Catering | Stainless steel prep tables, serving carts, ingredient bins, dish tables, buffet stations, mobile kitchen islands |
| Commercial & Office | Office chairs, mobile filing cabinets, AV carts, display racks, point-of-sale (POS) stands, exhibition displays |
| Industrial & Workshop | Light-duty workbenches, tool carts, assembly line equipment, mobile shelving, dust collectors |
| Electronics & ESD-sensitive Areas | Conductive TPR versions are available for electronics manufacturing and assembly to prevent electrostatic discharge |
| Hospitality & Institutional | Hotel luggage carts, housekeeping trolleys, library book carts, janitorial equipment |
Configuration Tip: For maximum maneuverability, use four swivel casters (allows movement in any direction). For straight-line stability with steering, combine two swivel (front) and two fixed (rear) casters. Where stationary parking is required, select models with double brakes that lock both wheel rolling and swivel mechanism for total stability.
