4 Inch Black Color PP M12*30 Double Ball Bearings With Double Brake Caster - Easy Assembling For Equipment
This caster is a high-performance, medium-duty swivel caster designed for equipment that requires both mobility and secure parking. The "double brake" locks both the wheel rotation and the swivel mechanism, providing total stability when engaged. Its "easy assembling" feature refers to the pre-assembled M12 threaded stem, which allows quick attachment to equipment with a matching nut or threaded insert. The primary purpose is to offer a durable, chemically resistant, and fully lockable mobility solution for industrial, laboratory, and food service equipment.
| Category | Specification / Feature | Functional Purpose |
|---|---|---|
| General Specs | Wheel Diameter: 4 inches (approx. 100mm) | Larger than 3" casters, this size rolls more easily over floor irregularities, thresholds, and debris, reducing push/pull effort. |
| Wheel Material: Polypropylene (PP), Black | High-strength, impact-resistant thermoplastic. Black color hides dirt and scuffs in heavy-use environments. | |
| Load Capacity: Approx. 100–150 kg per caster (depending on model) | Suitable for medium-duty equipment, carts, and machinery. Four casters can support 400–600 kg total load. | |
| Caster Type: Swivel with Double Brake | Allows 360° rotation for high maneuverability. The double brake engages both the wheel rolling and the swivel joint, preventing any movement. | |
| Mounting | Stem Type: M12 × 30 mm (Threaded) | Metric threaded stem (12mm diameter, 30mm length). Enables easy installation into pre-threaded equipment legs, nuts, or inserts. No tools required beyond hand-tightening or a basic wrench. |
| Easy Assembling: Pre-assembled stem with lock nut | The caster comes ready to install. The included lock nut allows secure fastening without complex hardware. | |
| Bearings | Bearing Type: Double Ball Bearings | Two sets of precision ball bearings (likely one in the wheel hub and one in the swivel raceway, or two in the wheel for extra smoothness). Provides ultra-smooth rolling, reduces friction, and supports heavier loads with less effort. |
| Braking | Brake Type: Double Brake (Total Lock) | A single pedal/lever engages two actions: (1) locks the wheel from rolling, (2) locks the swivel mechanism from rotating. This holds the equipment completely stationary and directionally fixed. |
| Material & Finish | Wheel Color: Black | Professional appearance; resistant to visible wear, stains, and discoloration. |
| Bracket Material: Steel with Zinc or Powder Coating | Heavy-gauge steel bracket provides structural strength. Coating offers corrosion resistance for indoor use. | |
| Environmental | Chemical Resistance: Excellent (PP) | Resists moisture, acids, alkalis, oils, and many solvents – ideal for food prep, labs, and factories. |
| Floor Protection: Non-marking | Black PP tread is non-marking, safe for most floors including sealed concrete, epoxy, and tile. |
Effortless Maneuverability: The 4" diameter combined with double ball bearings dramatically reduces rolling resistance. Equipment moves smoothly even under heavy loads, reducing operator fatigue.
Total Locking Security: The double brake is a critical safety feature. Unlike a single wheel brake, it locks both wheel rotation and swivel action, preventing any unintended movement – including drifting, pivoting, or rolling on an incline.
Quick & Tool-Free Installation: The M12×30 threaded stem and included lock nut allow for fast, easy assembly. Simply screw the stem into a pre-threaded hole or through a mounting plate and secure with the nut. No special tools or caster plates required.
Superior Load Support & Durability: The combination of a high-impact PP wheel, steel bracket, and double ball bearings provides a robust medium-duty caster capable of handling frequent use in demanding environments.
Low Maintenance & Clean Operation: Double ball bearings are sealed or shielded to keep out dirt and debris, reducing the need for lubrication. The PP wheel is easy to clean and resists chemical attack.
Versatile Aesthetic & Function: Black color blends well with industrial equipment, lab carts, and black-framed furniture. The double brake offers a professional, secure parking solution.
This caster is best suited for mobile equipment that needs to be moved regularly but also parked securely in a fixed position – especially in environments where chemicals, moisture, or hygiene are concerns.
| Application Area | Specific Use Examples |
|---|---|
| Industrial & Manufacturing | – Mobile workbenches and tool carts – Assembly line equipment (with parking brake) – Machine stands and portable conveyors |
| Food Service & Catering | – Stainless steel prep tables and kitchen islands – Ingredient bins and bulk food storage racks – Mobile dish tables and tray carts (brakes lock unit during use) |
| Laboratory & Medical | – Lab equipment stands (e.g., microscopes, centrifuges) – Medical instrument carts and crash carts – Chemical storage trolleys (PP resists spills) |
| Commercial & Retail | – Point-of-sale (POS) stands and kiosks – Mobile shelving units and display racks – Vending machines and service carts |
| Workshop & Garage | – Tool chests and rolling cabinets – Dust collectors and small machinery – Tire changing stands and jacks |
Configuration Tip: For a four-caster equipment, use four double-brake swivel casters to allow easy steering and the ability to lock all casters for complete stability. Alternatively, combine two double-brake swivel casters (front) with two fixed casters (rear) for straight-line tracking plus secure parking.
