75mm Heavy Duty Stem Caster Wheels M20*30 Stem Casters With Brakes

Product Overview

This caster is a heavy-duty swivel caster designed to provide maximum maneuverability for furniture and industrial machinery. Featuring a robust M20*30 threaded stem for secure mounting, an orange PVC wheel for durability, and double ball bearings for smooth rolling, this caster offers a reliable solution for equipment that requires frequent directional changes and effortless movement.

Features and Functional Purpose

• M20*30 Threaded Stem:

  • Feature: Equipped with a precision-engineered M20 thread diameter and 30mm stem length.

  • Functional Purpose: Designed for secure bolt-on mounting using nuts and washers. It provides a rigid, vibration-resistant attachment to machinery frames, furniture legs, or equipment sockets, ensuring the caster remains firmly in place under load.

• Orange PVC Wheel (3-Inch / 75mm Diameter):

  • Feature: Constructed from high-quality orange Polyvinyl Chloride (PVC), a hard-wearing thermoplastic.

  • Functional Purpose: Chosen for its excellent abrasion resistance and non-marking properties. It provides a durable rolling surface that protects indoor floors from scuffs while resisting wear from regular use.

• Double Ball Bearings:

  • Feature: Incorporates two precision-ground ball bearings within the wheel hub.

  • Functional Purpose: Engineered to significantly reduce rolling resistance and friction between the axle and the wheel. This allows for smooth, effortless rolling even under heavy loads.

• Full Swivel Mechanism:

  • Feature: Features a 360-degree rotating raceway with hardened steel balls.

  • Functional Purpose: Designed to allow the caster to pivot instantly in the direction of pull or push, providing superior maneuverability and ease of steering.

• Heavy-Duty Steel Frame:

  • Feature: The fork and stem base are constructed from heavy-gauge carbon steel with a protective zinc or chrome plating.

  • Functional Purpose: Built to withstand industrial environments, resist corrosion from moisture and chemicals, and support substantial weight without structural fatigue.

Functional Benefits

• Superior Maneuverability: The combination of the full swivel action and double ball bearingsallows for instant directional changes and smooth rolling, making it easy to navigate heavy equipment through tight spaces and around corners.

• High Load Capacity: The durable PVC wheel and robust steel frame provide a strong load-bearing capacity (typically 100-200+ lbs per caster), making it suitable for supporting heavy machinery and furniture.

• Floor-Friendly Operation: The orange PVC wheel is non-marking and non-staining, ensuring it will not leave unsightly scuff marks on polished concrete, tile, hardwood, or epoxy floors—critical for preserving indoor floor quality.

• Smooth & Quiet Performance: The precision bearings ensure quiet, low-effort movement compared to plain bore casters, reducing noise in work environments and operator fatigue during equipment relocation.

• Secure & Permanent Mounting: The M20*30 screw stem provides a bolt-like fastening that prevents the caster from pulling out or loosening over time, even under vibration or high lateral stress common in moving machinery.

• Chemical & Moisture Resistance: PVC material resists degradation from water, oils, grease, and mild industrial chemicals, ensuring a long service life in workshops, factories, or medical environments where cleaning agents are used.

Ideal Applications

• Industrial Machinery: Ideal for workshop machines, generators, compressors, conveyors, and light industrial equipment that needs to be repositioned frequently within a facility.

• Medical & Laboratory Equipment: Suitable for hospital beds, medical carts, diagnostic machines, and laboratory furniture where smooth, quiet movement and easy maneuverability are essential.

• Commercial Furniture: Perfect for heavy office furniture, filing cabinets, display racks, and workstations that require occasional reconfiguration.

• Service & Hospitality Carts: Used on janitorial carts, laundry carts, food service trolleys, and luggage carts that must navigate smoothly through corridors and around obstacles.

• Material Handling: Applied to platform trucks, dollies, and light-duty material handling equipment in warehouses and distribution centers.

• Audiovisual & IT Equipment: Suitable for speaker cabinets, equipment racks, and AV cartswhere smooth rolling and secure mounting protect valuable equipment during movement.
