Product Description

Thermoplastic Rubber (TPR) Medium Duty 75mm Swivel Casters For Equipment

Features

This caster is designed with specific components that dictate its performance. The features can be broken down by its material, structural design, and physical specifications.

Feature	Analysis
TPR (Thermoplastic Rubber) Wheel	The wheel tread is made from TPR, a material that combines the elasticity of rubber with the recyclability of plastic. It is known for being non-marking (won't leave scuffs on floors) and having high slip resistance. It also offers excellent shock absorption, which protects both the equipment and the floor surface.
Double Ball Bearings (Swivel)	The caster features a double ball raceway in the swivel head. This design allows the caster to rotate 360 degrees smoothly and handle changes in direction with ease, even under load. It ensures greater maneuverability and durability compared to single-row bearings.
Medium Duty & 75mm Size	The "medium duty" rating suggests it is built for regular use with a moderate load capacity, suitable for equipment that is moved frequently but does not carry extremely heavy industrial loads. The 75mm (approx. 3-inch) wheel diameter is a common size that balances rolling ease with a low mounting height.
Color: Blue	While primarily aesthetic for branding or color-coding, the blue color typically indicates the specific material formulation (TPR) and is often used to distinguish it from other wheel types (like gray or black rubber) in a product line.

Function

The function describes how the caster performs its job of moving equipment.

Smooth and Quiet Operation: The primary function of the TPR wheel is to provide a quiet and smooth ride. The material's inherent flexibility dampens vibration and reduces noise, which is a critical function in noise-sensitive environments like hospitals or offices.
Floor Protection: The TPR tread functions as a protective layer between the equipment and the floor. It ensures that the caster will not mark or damage delicate surfaces such as hardwood, tile, marble, or epoxy-coated floors.
Effortless Maneuverability: The double ball bearing swivel mechanism allows the caster to instantly change direction in response to movement. This makes the equipment highly agile, allowing it to navigate around corners and obstacles with minimal effort.
Shock Absorption: It functions as a cushion, absorbing shocks and impacts from uneven surfaces. This protects the payload (e.g., medical equipment, fragile goods) from vibration and jarring during transport.

Application Analysis

Given the combination of quiet operation, floor protection, and smooth swiveling, this caster is ideal for controlled indoor environments where noise and floor damage are primary concerns.

Medical and Healthcare Settings: These casters are a standard choice for hospital beds, medical carts, IV stands, and gurneys. The quiet operation helps maintain a peaceful environment for patients, while the non-marking tread protects sensitive hospital flooring.
Office and Commercial Furniture: Perfect for office chairs, filing cabinets, mobile pedestals, and display stands. They allow for easy reconfiguration of spaces without causing noise disruptions or scratching floor surfaces.
Retail and Hospitality: Used on shopping carts, retail display racks, service carts, and hotel luggage carts. The smooth rolling enhances the customer experience, and the non-marking wheels keep retail floors looking pristine.
Institutional and Light Industrial: Suitable for library book carts, school equipment, food service trolleys, and laundry carts. The chemical and moisture resistance of TPR makes it viable in settings where occasional exposure to water or mild chemicals occurs.
