Replacing an old castor? Measure between the centres of two fixing holes along the long edge, then across the short edge, and compare with the hole centres above. Allow the swivel radius as clear space around each castor so it can turn freely.
Load check
How we work it out: on a real floor one castor is often carrying little or nothing, so we share the weight across one fewer castor than you fit (with 3 castors, across all 3). Tick the box to add a 30% margin for rough use.

- Rolls poorly over debris and cables
Details & FAQs
Medium Duty Jacking Castors
Get reliable movement and support for your equipment, then lift it back onto its own feet. This medium duty jacking castor combines a 125mm white nylon swivel wheel with a built-in screw jack that gives 76mm of lift. Turn the jack with a 24mm spanner to lower the wheel and raise your machine for moving, then wind it back up so the equipment rests firmly in place. The durable, wear-resistant nylon wheel and roller bearing give smooth rotation and easy directional changes, and each castor is rated for 150kg.
It fixes to your equipment with a 130 x 75mm mounting plate with four 11mm holes on 102 x 51mm centres. The castor is 365mm tall and the jacking unit reaches 441mm when fully extended. Check the plate size, hole centres and jacking height against your equipment before ordering.
