5 Inch Brown TPR Medium Duty Double Ball Bearing Caster With Double Brake System For Equipment
Feature and Functional Purpose
The primary purpose of this caster is to provide a robust, smooth-rolling, and highly stable mobility solution for medium-duty equipment, where both ease of movement and secure locking are critical.
5-Inch Diameter & Brown TPR Wheel: The 5-inch wheel with a brown Thermoplastic Rubber (TPR) tread is designed for a balance of load capacity and maneuverability. The brown color is often chosen for industrial settings where it hides dirt well, while the TPR material provides a soft, quiet ride and high traction . The wheel typically features a "donut tread" design on a durable polyolefin core, which offers easier mobility over standard flat tread wheels .
Double Ball Bearings: This refers to the precision bearings within the wheel hub. "Double ball bearings" provide smoother rolling with less effort compared to single bearings or plain bearings, especially under heavy loads. They are designed for maintenance-free operation and long life in demanding applications .
Double Brake System: A comprehensive braking mechanism that typically locks both the wheel rotation and the swivel action simultaneously. This ensures the equipment remains completely immobile—preventing both rolling and swiveling—for maximum safety during use or when parked.
Medium Duty Construction: The caster is engineered for medium-duty applications, with common load ratings around 350 lbs per caster, supporting a total equipment weight of up to 1,400 lbs for a set of four . The frame often features double ball bearing heat-treated raceways for smooth swiveling under load .
Functional Purpose: To safely and easily move medium-weight equipment into precise positions, and then engage the double brake to create a completely stable, immobile platform during operation, ensuring user safety and equipment stability.
Functional Benefits
The combination of the 5-inch TPR wheel, double ball bearings, and double brake system offers significant operational advantages:
Feature
Functional Benefits
5" Brown TPR Wheel
Provides a quiet, smooth ride with high traction. The soft tread absorbs shock and vibration, protecting both the equipment and floors. The brown color is practical for hiding dirt in industrial environments, while the TPR material is non-marking and resists many chemicals .
Double Ball Bearings
Ensures effortless rolling and superior load distribution. The precision bearings significantly reduce rolling resistance, making it easier to maneuver heavy equipment. They are designed for long life and maintenance-free operation, even under continuous use .
Double Brake System
Delivers maximum stability and safety by locking both the wheel and swivel. This prevents any unwanted movement, "creep," or swiveling, which is essential for equipment that must remain perfectly still during operation or on inclines.
Medium Duty Construction
Provides a high load capacity (up to ~350 lbs per caster) in a durable package. The heat-treated raceways and robust design ensure reliability and a long service life in demanding commercial and industrial settings .
Ideal Applications
Given its size, load capacity, smooth-rolling bearings, and comprehensive locking system, this caster is perfectly suited for medium-duty equipment in various industrial, commercial, and institutional environments.
Industrial Carts and Dollies:
Platform Trucks and Warehouse Carts: For transporting parts, boxes, or materials in warehouses and factories. The double ball bearings ensure easy rolling even when fully loaded .
Drywall Carts, Welding Carts, and Wall Panel Carts: Ideal for job sites where equipment needs to be moved over rough or uneven surfaces, and then locked securely in place for work .
Commercial and Food Service Equipment:
Food Service Carts and Hotel Housekeeping Carts: The quiet, non-marking TPR wheels are perfect for noise-sensitive environments like hotels and restaurants. The double brake keeps carts stationary during loading or cleaning .
Heavy-Duty Kitchen Equipment: For larger mixers, preparation tables, or holding cabinets that require both easy mobility and rock-solid stability during use.
Institutional and Freight Applications:
Hospital Equipment and Medical Carts: Suitable for heavier medical equipment that needs quiet, smooth movement and secure locking in patient areas.
Freight Terminals and Mail Carts: For moving heavy bins and packages in shipping/receiving areas, where durability and easy rolling under load are essential .
