White Ball Bearings PP Caster 75mm Polypropylene 3 Inch Castor Wheels

3 Inch White Color Double Ball Bearings Caster Wheel, with Double Brake, And Blue-white Zinc Resistant Coating For Machine And Equipment

Features

1. Wheel Size and Color: The caster features a 3-inch wheel in a white color. The wheel material is not specified in the search results but is likely a durable, non-marking polymer like polypropylene or polyurethane, which are common for industrial casters .
2. Smooth Movement: It is equipped with double ball bearings. This feature ensures a smooth and reliable swiveling action, making the equipment easy to maneuver .
3. Advanced Corrosion Protection: The caster features a blue-white zinc coating on its metal parts (like the fork and mounting plate). This is a type of zinc plating, often including a clear or blue-tinted chromate post-treatment, that provides excellent corrosion resistance . This protective layer prevents rust from moisture, humidity, and spills, significantly extending the life of the caster .
4. Dual Braking System: The inclusion of a double brake system is designed for maximum security. While the specific type isn't detailed in the search results, a "double brake" on a swivel caster usually means one brake locks the wheel's rotation while another locks the swivel mechanism itself, preventing any movement or swiveling.
5. Easy to Clean: The non-porous surface of the zinc coating and the wheel material makes this caster easy to sanitize, as it resists the buildup of dirt, bacteria, and other contaminants .

Function

1. Provides Secure Mobility and Control: The 3" wheel and swivel mechanism allow for precise positioning of machinery and equipment. When movement is not desired, the double brake system can be engaged to lock both the wheel and the swivel, keeping the equipment firmly and safely in place.
2. Ensures Long-Lasting Durability: The blue-white zinc coating serves the critical function of protecting the caster's metal framework from rust and corrosion. This is essential for maintaining the structural integrity and load-bearing capacity of the caster in challenging environments .
3. Facilitates Quiet and Smooth Operation: The double ball bearings ensure the caster rolls and swivels smoothly and quietly, which reduces noise in the workplace and makes moving heavy equipment less strenuous .
4. Maintains Hygiene and Cleanliness: The corrosion-resistant and non-porous surfaces prevent the caster from becoming a breeding ground for germs and make it simple to wipe down and keep clean, which is vital in regulated industries .

Ideal Applications

Given its combination of corrosion resistance, hygienic design, and secure locking, this caster is perfectly suited for environments where cleanliness and stability are paramount:

1. Medical and Healthcare: Ideal for hospital beds, medical carts, instrument stands, and other equipment that requires frequent cleaning with harsh disinfectants. The locking brakes ensure patient safety when equipment must remain stationary.
2. Food Service and Processing: Perfect for food preparation tables, shelving units, and utility carts in commercial kitchens. The corrosion-resistant coating can withstand regular washdowns, and the non-marking wheel helps maintain floor hygiene.
3. Laboratory and Pharmaceutical: Suitable for sensitive equipment and chemical carts in labs where resistance to mild chemicals and the need for a sterile environment are critical .
4. Industrial Machinery: For machinery and equipment on factory floors that are exposed to coolants, oils, or occasional wet conditions, this caster provides reliable, rust-proof mobility with the ability to lock the equipment firmly in place during operation.
5. Cleanroom Environments: The easy-to-clean, non-shedding surfaces of the wheel and zinc coating make these casters a strong candidate for use in cleanrooms and other controlled environments.
