Product Description

5 InchThermoplastic Rubber (TPR) Medium Duty 125mm Double Brake Casters For Equipment

 

125mm Thermoplastic Rubber (TPR) Medium Duty Casters with Double Brake For Equipment

 

Features

 

The 5-inch TPR medium duty caster is designed with a combination of materials and structural elements to provide reliable mobility for various equipment. Its core features include:

  1. Wheel Material (TPR): The wheel is made of Thermoplastic Rubber (TPR), an elastomeric material known for its high elasticity and floor-friendly properties . TPR is a common material for casters requiring quiet operation and shock absorption, as it does not leave marks on flooring .
  2. Dimensions and Load: It has a standard wheel diameter of 125mm (5 inches) with a typical tread width of around 32mm . As a medium-duty component, its load capacity generally ranges from 60kg to 200kg per caster, depending on the specific model and construction .
  3. Dual Brake Mechanism: This caster features a "double brake" (also known as "total lock" or "前雙剎車輪"). This mechanism is designed to lock both the wheel's rotation and the swiveling movement of the caster simultaneously, providing comprehensive stability .
  4. Construction and Bearings: The支架 (frame) is typically made from formed steel with a protective zinc or chrome plating for durability and corrosion resistance . Many models incorporate high-quality ball bearings (e.g., double ball bearings or #6002 bearings) to ensure smooth and efficient rolling . Some designs also include dust-proof rings or covers to prevent debris from entering the bearing mechanism, extending the caster's service life .

 

Function

 

The combination of features allows this caster to fulfill several key functional roles:

  1. Quiet and Smooth Operation: The soft TPR material significantly dampens vibration and reduces noise generated during movement, making it ideal for indoor environments where quietness is a priority . The precision ball bearings contribute to a smooth, low-effort glide.
  2. Floor Protection: Unlike harder materials such as nylon or steel, TPR wheels are non-marking and gentle on various floor surfaces. They perform well on hard floors like tiles, resin, and wood, providing good traction without causing damage .
  3. Enhanced Stability and Safety: The primary function of the double brake is to ensure equipment stays precisely in place when parked. By securing both the wheel and the swivel, it prevents any unwanted movement, rolling, or castor "flutter," which is critical for safety on inclined surfaces or during stationary operations .
  4. Shock Absorption: The inherent elasticity of TPR allows the wheel to absorb shocks and vibrations from uneven surfaces, protecting sensitive equipment or fragile payloads being transported .

 

Application Analysis

 

Due to its functional characteristics, this caster is well-suited for a wide variety of applications across different sectors. Its quiet, clean, and stable performance makes it a preferred choice for indoor environments .

  1. Medical and Healthcare: Frequently used on hospital beds, medical equipment stands, diagnostic devices, and service carts where hygiene, quietness, and secure locking are essential .
  2. Industrial and Commercial: Ideal for tool carts, workbenches, assembly line trolleys, and material handling equipment in workshops and factories where medium loads are moved manually .
  3. Laboratory and Research: Commonly found under laboratory instruments, sample storage racks, and cleanroom equipment due to their chemical resistance, quiet rolling, and ability to protect sensitive floorings .
  4. Hospitality and Food Service: Suitable for food trolleys, room service carts, and other service equipment in hotels and restaurants where maneuverability and noise reduction are valued .
  5. Data and Technology: Applied to server racks, data cabinets, and other IT equipment to facilitate maintenance and reconfiguration in data centers .
  6. Retail and Display: Used for shopping carts, display stands, and shelving units in retail environments, allowing for easy rearrangement and quiet movement .
