The Waterproof Thread Stem with Brake Medium Duty Industrial Caster Wheels is a versatile and rugged mobility solution designed for industrial applications. Available in 3", 4", and 5" sizes, these caster wheels are crafted with PP/PU/TPR/Nylon materials to deliver exceptional performance across diverse work environments. The waterproof design and integrated brake system set it apart, ensuring reliability in damp or wet industrial settings while providing secure locking for safety. With PVC bearings, these medium-duty caster wheels offer smooth rotation and durable operation, making them ideal for enhancing efficiency in warehouses, factories, and workshops. Whether moving heavy equipment, storage carts, or machinery parts, this caster wheel combines strength, versatility, and safety to meet the demands of industrial workflows. Its thread stem mounting ensures easy installation, making it a practical choice for businesses seeking reliable mobility solutions.
The waterproof design protects internal components from moisture, making the caster wheel suitable for use in damp industrial environments, outdoor storage areas, or facilities with frequent cleaning protocols. It resists rust and corrosion, ensuring long-term durability.
Equipped with a reliable brake mechanism, the caster wheel allows for secure locking in place, preventing unintended movement of equipment. The brake is easy to engage and disengage, providing convenience and safety for workers.
Constructed with PP (Polypropylene), PU (Polyurethane), TPR (Thermoplastic Rubber), and Nylon options, the caster wheel offers flexibility to suit different surface types and load requirements. Each material provides unique benefits, from shock absorption (PU) to chemical resistance (Nylon).
Featuring PVC bearings, the caster wheel ensures smooth rotation and minimal friction, even under medium-duty loads. The bearings reduce noise and wear, extending the service life of the wheel.
The thread stem design enables easy and secure installation on a wide range of industrial equipment, including carts, racks, and machinery. It provides a stable connection that withstands frequent movement and vibration.
Ideal for storage carts, pallet jacks, and material handling equipment in warehouses. The caster wheel’s durability and smooth rolling make it suitable for moving heavy loads across concrete or asphalt floors.
Suitable for use on production line equipment, tool carts, and assembly tables. The waterproof design and brake system make it safe for use in factories with wet processes or cleaning routines.
Perfect for outdoor storage areas, construction sites, and facilities with exposure to moisture. The waterproof construction resists rust and damage, ensuring reliable performance in harsh conditions.
Can be used for display racks, delivery carts, and stock transport equipment in retail stores, supermarkets, and distribution centers. The multi-material options adapt to different floor surfaces, from tile to concrete.
