M20*30 Casters With Screw Stem Orange 3 Inch Stem Casters For Furniture

Product Overview

This caster is a heavy-duty mobility solution designed to provide smooth movement and secure stationary locking for a variety of equipment. Featuring a durable Orange PVC wheel, a precise M20*30 threaded stem, and a comprehensive double brake system, it combines load-bearing strength with operational safety.

Features

• Threaded Stem: Equipped with an M20*30 screw stem (M20 thread diameter, 30mm length). This allows for secure fastening with nuts and washers, providing a rigid and permanent mount to machinery or furniture frames.

• Wheel Material & Size: Features a 3-inch (75mm) wheel made of Orange PVC (Polyvinyl Chloride) . PVC is a non-marking, hard-wearing thermoplastic.

• Bearing System: Incorporates Double Ball Bearings within the wheel hub. This precision bearing setup reduces friction between the axle and the wheel.

• Brake Type: Includes a Double Brake (Total Lock) mechanism. This system acts on both the swivel raceway (to prevent turning) and the wheel tread (to prevent rolling).

• Frame Construction: The housing and fork are typically constructed from heavy-gauge carbon steel with a protective zinc or chrome plating to resist rust.

Functional Benefits

• Superior Stationary Safety (The "Double Brake" Advantage): The primary benefit is the Total Lock functionality. By immobilizing both the wheel rotation and the swivel action, it prevents the equipment from drifting, rolling, or casters from swiveling out of alignment. This is critical when machinery is in operation or furniture must remain perfectly still.

• Effortless Maneuverability: The Double Ball Bearings significantly reduce the effort required to push or pull the equipment. They ensure the wheel rolls smoothly even under load and swivels easily to change direction.

• Durability & Floor Protection: The PVC wheel offers high abrasion resistance, meaning it won't wear down quickly on rough concrete. It is also non-marking, so it won't leave scuff marks on polished floors, tiles, or wood.

• Secure Mounting: The M20*30 screw stem provides a bolt-like fastening. Unlike friction-fit stems, this threading ensures the caster will not pull out of the socket, even under vibration or high lateral stress common in machinery.

• Chemical & Moisture Resistance: PVC is resistant to oil, grease, water, and many chemicals, making cleanup easy and prolonging the life of the wheel in messy environments.

Ideal Applications

• Industrial Machinery: Ideal for workshop machines, generator sets, compressors, and conveyor equipment that need to be positioned precisely and then locked down to prevent vibration-induced movement.

• Medical & Laboratory Equipment: Suitable for heavy medical carts, dialysis machines, and laboratory furniture where hygiene (easy-clean PVC) and patient safety (secure brakes) are non-negotiable.

• Commercial Furniture: Perfect for heavy-duty office credenzas, industrial shelving units, and workbenches that require occasional reconfiguration but must stay put during use.

• Service & Hospitality Carts: Used on janitorial carts, laundry carts, and food service trolleysthat need to navigate smoothly through corridors and stay stationary during loading/unloading.

• Audiovisual & IT Racks: Applied to server racks and AV equipment cases, where the double brake prevents expensive equipment from rolling during setup or connection.
