M12*30 4 Threaded Stem Swivel Caster 100mm 4 Inch Threaded Stem Casters

4 Inch White Color PP Material Double Ball Bearing M12*30 Caster with Double Brake System - Easy Assembling For Equipment

Feature Analysis

This caster is designed for applications requiring a balance of chemical resistance, cleanliness, and reliable locking, all in an easy-to-install package.

1. Polypropylene (PP) Wheel: The wheel is made of white polypropylene, a lightweight thermoplastic known for its high strength-to-weight ratio and excellent resistance to chemicals and moisture.
2. Double Ball Bearings: The wheel hub is equipped with double ball bearings to ensure smooth rolling, and the swivel head also features a double ball bearing raceway for effortless steering .
3. M12*30 Threaded Stem: This mounting type features an M12 threaded stem with a length of 30mm, designed to screw directly into a threaded hole or through a mounting plate with a matching nut on equipment.
4. Double Brake System: The caster features a dual-function brake pedal that simultaneously locks both the wheel's rotation and the swivel mechanism .
5. Easy Assembling: As a stem-mounted caster, installation is straightforward. It simply screws into a pre-threaded hole (or uses a nut) on the equipment, requiring no additional mounting plates or complex tools.

Functional Benefits

The combination of materials and design offers specific advantages for various settings.

• Excellent Chemical & Moisture Resistance: Polypropylene is inherently resistant to a wide range of chemicals, oils, solvents, and moisture. This makes the wheel easy to clean, sterilize, and ideal for environments where spills are common or hygiene is critical.
• Smooth and Hygienic Movement: The white PP surface is non-porous and easy to wipe down. The double ball bearings ensure the equipment rolls and turns with minimal effort, which is crucial in busy environments where noise and efficiency matter .
• Secure and Stable Positioning: The double brake system provides total immobility when engaged. By locking the wheel and the swivel, it prevents the equipment from rolling or drifting, ensuring safety during use or when parked on an incline .
• Clean and Aesthetic Appearance: The white color of the wheel gives it a clean, professional look that is often preferred in medical, food service, or retail settings to match light-colored equipment and maintain a sterile appearance.
• Simple, Secure Installation: The M12 threaded stem provides a very strong and secure direct connection to the equipment frame. Installation is as simple as screwing it into a pre-tapped hole, making it a fast and sturdy mounting solution.

Ideal Applications

Given its chemical resistance, clean appearance, and secure locking, this caster is perfectly suited for the following applications:

1. Medical & Healthcare Environments: Ideal for hospital beds, medical carts, equipment stands, and dental chairs where hygiene, chemical resistance to cleaning agents, and quiet, smooth maneuverability are essential .
2. Food Service & Catering: Perfect for food preparation tables, service carts, and kitchen equipment that require frequent washing and resistance to food acids, oils, and greasy substances.
3. Laboratory & Pharmaceutical: Suitable for lab equipment stands, instrument carts, and mobile workstations where resistance to chemical spills and the ability to maintain a clean, sterile surface are critical.
4. Institutional & Hospitality: Great for housekeeping carts, laundry trolleys, and light-duty service carts in hotels, schools, and hospitals where a clean look and reliable brake are needed.
5. Light Industrial & Clean Rooms: Can be used for light-duty assembly line trolleys, parts bins, and equipment in clean room environments or areas where chemical resistance is more important than heavy load capacity.
