Product Description

3 Inch Thermoplastic Rubber (TPR) M12*30 Stem Screw Caster Wheel Double Brake

Here is a breakdown of the features, functions, and applications for a 3-inch Thermoplastic Rubber (TPR) caster wheel with an M12*30 threaded stem and double brake.

(1) Features

This caster combines material properties and design elements for specific performance benefits.

Feature Category	Specific Feature	Description / Benefit
Wheel Material	Thermoplastic Rubber (TPR)	An elastomer that blends the elasticity of rubber with the durability and processability of plastic . It is known for being quiet, flexible, and versatile .
	Floor Protection	TPR is a non-marking material that will not scuff or leave marks on delicate floors like hardwood, tile, or epoxy .
	Shock Absorption	Provides excellent shock absorption, reducing vibrations and ensuring smooth rolling over uneven surfaces .
	Durability	Offers high wear resistance and can withstand exposure to water, chemicals, and a wide range of temperatures (typically -40°F up to 257°F / 125°C) .
Mounting Type	M12*30 Threaded Stem	An M12 threaded stem (12mm diameter) that is 30mm long. This design allows for secure mounting into a pre-threaded hole or with a locknut .
	Easy Installation	Threaded stems are generally easier to install and replace than plate casters, often requiring no tools for removal .
	Space-Efficient	Ideal for applications with limited space on the equipment leg or frame .
Braking System	Double Brake	This mechanism typically locks both the wheel's rotation and the swivel action of the caster, holding the equipment securely in place.

(2) Functions

The features above translate into the following core functions for the equipment it's attached to:

Smooth and Quiet Mobility: The TPR wheel material ensures the equipment rolls quietly with minimal vibration, which is critical in noise-sensitive indoor environments .
Reliable Locking: The "double brake" mechanism allows the user to lock the equipment in placeby engaging both the wheel and the swivel, providing stability and safety when stationary.
Secure Attachment: The M12*30 threaded stem provides a strong, direct, and secure connection to the equipment, ensuring the caster won't detach during use . It can also be used for minor height adjustments .
Protection for Flooring: The TPR material safeguards high-quality or sensitive flooring surfaces from damage, marks, and scratches.
Maneuverability: The wheel's flexibility and shock absorption allow for easy movement and navigation around obstacles .

(3) Applications

Given its features, this specific caster is well-suited for a variety of indoor applications where floor protection, quiet operation, and secure locking are important.

Medical and Healthcare Settings: Ideal for hospital beds, medical carts, and equipment stands where quiet operation, hygiene, and the ability to lock in place are essential .
Office Furniture: Commonly used on office chairs, filing cabinets, and desk pedestals to allow for smooth movement while protecting office flooring .
Commercial and Retail Displays: Suitable for retail carts, shelving units, and display racks that need to be moved quietly and then locked for stability during customer use .
Institutional Environments: A good choice for equipment in schools, libraries, and hotels where noise reduction and floor care are priorities .
Light Industrial and Warehouse Use: Can be used on tool carts, assembly line trolleys, and other light-duty material handling equipment in factories or warehouses .
