The 100mm castor stands 127mm tall and supports up to 120kg per unit (360kg for a set of four), making it well suited to lighter trolleys, benches, and display units. The 125mm castor stands 157mm tall and supports up to 140kg per unit (420kg for a set of four), offering greater ground clearance and improved rolling performance over minor floor irregularities. As a general rule, choose the 100mm for moderate-duty, low-clearance applications and the 125mm where heavier loads or slightly uneven floors are involved. Always divide your total equipment weight (including contents) by four and apply a safety margin before selecting your load rating.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"fc-faq-item\"\u003e\n\u003cdiv class=\"fc-faq-q\"\u003eWill these castors mark or damage my floors?\u003c\/div\u003e\n\u003cdiv class=\"fc-faq-a\"\u003eThese castors are fitted with a blue rubber tread rated at 75 Shore A — a hardness level that balances load-bearing performance with floor protection. The rubber compound is formulated to be non-marking on smooth and semi-smooth surfaces including sealed concrete, vinyl, ceramic tile, and hardwood. For particularly sensitive or polished floors, we recommend confirming suitability with a short rolling test before full deployment. The wider tread on the 125mm option (37.5mm versus 32mm on the 100mm) distributes load over a greater contact area, further reducing the risk of surface indentation under heavy loads.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"fc-faq-item\"\u003e\n\u003cdiv class=\"fc-faq-q\"\u003eHow are these castors fitted, and what fixings are required?\u003c\/div\u003e\n\u003cdiv class=\"fc-faq-a\"\u003eBoth sizes use a four-hole top plate measuring 100mm x 85mm, with hole centres of 80mm (length) x 60mm (width) and a plate hole diameter of 10mm. This is a standard top plate configuration compatible with a wide range of commercial and industrial equipment frames. Fitting requires four M8 or M10 bolts (depending on your equipment's thread specification), washers, and locking nuts — these are not supplied and should be sourced separately to match your specific application. Ensure the mounting surface is flat, clean, and structurally sound before installation.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"fc-faq-item\"\u003e\n\u003cdiv class=\"fc-faq-q\"\u003eAre these fixed castors suitable for use alongside swivel castors on the same equipment?\u003c\/div\u003e\n\u003cdiv class=\"fc-faq-a\"\u003eYes — fixed castors are commonly paired with swivel castors in a four-castor configuration to achieve both directional stability and manoeuvrability. The standard arrangement is to fit two fixed castors at the rear of the equipment (to maintain a straight travel line) and two swivel castors at the front (to allow steering and turning). Both the 100mm and 125mm fixed castors in this listing share the same top plate dimensions (100mm x 85mm) and hole pattern as many compatible swivel castor options, making mixed configurations straightforward. Always ensure all castors in a set share the same wheel diameter to maintain a level, stable platform.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"fc-note-box\"\u003e* Load ratings stated are per individual castor under controlled static conditions. For dynamic applications — including equipment that is pushed, pulled, or subject to impact loading — apply a minimum safety factor of 1.5 to 2 times the calculated per-castor load.
