Yellow PP Caster Wheels 100mm Polypropylene Caster Wheels OEM

100mm Yellow Color Double Ball Bearings Caster Wheel with Double Brake system with Blue-white Zinc Resistant Coating For Machine And Equipment

Features & Functional Purpose

This caster is a high-performance component designed to make industrial equipment both highly maneuverable and completely secure when stationary.

• Wheel: 100mm diameter wheel with a yellow polyurethane (PU/TPU) tread . This material is often vulcanized onto a strong, lightweight die-cast aluminum core . The color is typically a "honey yellow" (RAL 1005) or light brown .
• Bearings: The wheel itself rotates on precision ball bearings for smooth rolling . Furthermore, the swivel head features a double ball bearing raceway, which allows the caster to change direction smoothly and effortlessly even under heavy loads .
• Brake System: Equipped with a double brake system (sometimes called a total lock or central brake). This single mechanism simultaneously locks the wheel's rotation and the swivel function of the fork . One model specifies this as a "double brake with overrun," suggesting it securely prevents any movement .
• Coating: The pressed steel fork and housing are finished with a zinc-plated, blue-passivated coating that is Cr6-free (hexavalent chromium-free), making it more environmentally friendly .
• Mounting: Features a standard plate mounting design for easy attachment to equipment .

The primary functional purpose of this design is twofold: to allow for the precise and effortless maneuvering of heavy machinery and to provide a reliable locking mechanism that holds the equipment firmly in place during use, preventing any unintended movement or swivel.

Functional Benefits

1. Maximum Safety and Stability: The double brake system provides the highest level of security. By locking both the wheel and the swivel, it prevents equipment from rolling away or the caster from swiveling out of alignment, which is crucial on slopes, vibrating machinery, or during precision tasks .
2. Superior Corrosion Resistance: The blue-white zinc coating offers excellent protection against rust and oxidation, ensuring the caster's longevity in demanding environments like factories, commercial kitchens, or outdoors .
3. Exceptional Load Capacity & Durability: With a robust steel fork, aluminum wheel center, and high-quality bearing system, this caster is built for heavy-duty use. For example, a similar model has a maximum load capacity of 180kg . It is suitable for towing applications and withstands significant shock and impact .
4. Smooth Manoeuvrability and Low Effort: The combination of a double ball bearing swivel head and precision ball bearings in the wheel means that even very heavy loads can be steered and moved with minimal physical effort from the operator .
5. Floor Protection and Quiet Operation: The polyurethane tread is non-marking, soft on all floor types, and operates quietly, unlike hard plastic or metal wheels. It also offers good resistance to abrasion, oils, and many chemicals .

Ideal Applications

Given its robust safety features and high performance, this caster is perfectly suited for applications where both mobility and absolute stationary security are required.
