4" TPR Threaded Stem Caster M12, 220 lbs Load, 5.04" Height, Pkg Qty 20

Overview

This medium-duty swivel caster is engineered for commercial and industrial environments requiring reliable mobility, floor protection, and noise reduction. Featuring a thermoplastic rubber (TPR) wheel mounted on a robust threaded stem, the unit delivers smooth rolling performance while absorbing shock and vibration. With a load capacity of 220 lbs per caster, it is ideal for moving equipment carts, medical devices, food service trolleys, and light manufacturing fixtures. The non-marking TPR tread ensures clean operation on sensitive flooring surfaces such as epoxy, tile, or polished concrete, making it suitable for facilities where cleanliness and quiet operation are critical.

Key Features

Non-marking TPR wheel protects delicate floor surfaces Quiet rolling operation reduces ambient noise in workspaces Shock-absorbing tread minimizes vibration transmission to loaded equipment 360-degree swivel capability for precise maneuverability in tight spaces Secure M12 threaded stem prevents accidental dislodgement during transport Corrosion-resistant hardware extends service life in humid or washdown environments Medium-duty construction balances strength with lightweight portability
