125mm O Series Castor
350kg Capacity
Fixed Plate

The OBQ125/HZF is a 125mm blue rubber fixed castor, rated to 350kg per castor. Made by Fallshaw in Australia, it pairs a blue high resilience rubber wheel on twin sealed precision bearings with a zinc Core Coat fork, so a loaded trolley moves with little push effort. The rigid zinc-plated fork holds the trolley on a straight line, so it works alongside swivel castors at the front for steady tracking down long runs.

Why Blue Rubber

Rubber is the quiet option. It soaks up the vibration and noise that nylon and polyurethane pass into the trolley, and it is non-marking, so it protects tiled, vinyl and polished floors. That makes the 125mm blue rubber castor a good fit for workshop and warehouse trolleys, hospitality gear and institutional equipment where quiet running and floor protection matter.

Bolts Straight Onto Existing Trolleys

The 130mm x 100mm top plate shares the same footprint as the Rex EHI and MHD industrial castors, so it swaps in without redrilling. The wheel is replaceable too, so a worn tread means a new wheel, not a new castor.

Fixed, Swivel and Braked Versions

The 125mm O Series also comes as a swivel plate (OBQ125/OZP) and a swivel plate with total brake (OBQ125/OZPTB). All share the same wheel, height and plate, so you can mix them on one trolley. Bulk and trade pricing is available on full sets, and every variant is listed on the O Series castor range page.
