With a total height of 122mm and a per-castor load capacity of 85kg — equating to 255kg across a standard set of four — this option is suited to heavier equipment and more demanding handling environments. The larger wheel diameter also reduces rolling resistance compared to smaller sizes, making it easier to push loaded equipment across longer distances. The top plate dimensions remain consistent with the other sizes in this range (60mm x 67mm, 6mm hole diameter, 48mm and 38mm hole centres), ensuring compatibility with the same range of equipment frames.\u003c\/p\u003e\n\u003cdiv class=\"fc-sub-title\"\u003eApplications\u003c\/div\u003e\n\u003cul class=\"fc-app-list\"\u003e\n\u003cli\u003eIndustrial carts, platform trolleys, and goods transport equipment in warehouse environments\u003c\/li\u003e\n\u003cli\u003eHeavy-duty storage racking and mobile shelving units in distribution and logistics settings\u003c\/li\u003e\n\u003cli\u003eInstitutional laundry trolleys, linen carts, and equipment in healthcare facilities\u003c\/li\u003e\n\u003cli\u003eWorkshop machinery bases and mobile workbenches requiring a stable fixed castor\u003c\/li\u003e\n\u003cli\u003eHospitality and events equipment including bar trolleys, staging units, and service carts\u003c\/li\u003e\n\u003cli\u003eRetail stockroom and back-of-house equipment where higher load capacity is needed\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c!-- FAQs --\u003e\n\u003cdiv class=\"fc-section-title\"\u003eFrequently Asked Questions\u003c\/div\u003e\n\u003cdiv class=\"fc-faq-wrap\"\u003e\n\u003cdiv class=\"fc-faq-item\"\u003e\n\u003cdiv class=\"fc-faq-q\"\u003eWhat is the difference between a fixed castor and a swivel castor, and which do I need?\u003c\/div\u003e\n\u003cdiv class=\"fc-faq-a\"\u003eA fixed castor has a static bracket that allows the wheel to roll in one direction only — forwards and backwards — providing straight-line movement and directional stability. A swivel castor has a rotating head that allows the wheel to turn in any direction, making it easier to steer and manoeuvre equipment around corners. In most practical applications, equipment is fitted with a combination of both: fixed castors at the rear to maintain a straight rolling path, and swivel castors at the front to allow steering. If your equipment will only ever need to move in a straight line, or if you are replacing existing fixed castors, these fixed top plate castors are the correct choice.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"fc-faq-item\"\u003e\n\u003cdiv class=\"fc-faq-q\"\u003eHow do I calculate the correct load capacity for my application?\u003c\/div\u003e\n\u003cdiv class=\"fc-faq-a\"\u003eTo determine the minimum load capacity required per castor, divide the total weight of your equipment — including its maximum intended contents — by the number of castors being fitted. For example, if your trolley and its load weigh 200kg and you are fitting four castors, each castor must support a minimum of 50kg. It is strongly recommended to apply a safety margin of at least 25–30% above this calculated figure to account for dynamic loads, uneven weight distribution, and variations in floor surface. Based on this guidance, the 50mm option (65kg per castor) is suitable for lighter furniture and equipment, the 75mm option (75kg per castor) covers general commercial use, and the 100mm option (85kg per castor) is appropriate for heavier or more demanding applications.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"fc-faq-item\"\u003e\n\u003cdiv class=\"fc-faq-q\"\u003eHow do I fit a top plate castor, and what fixings are required?\u003c\/div\u003e\n\u003cdiv class=\"fc-faq-a\"\u003eTop plate castors are fixed directly to the underside of equipment using bolts or screws passed through the four holes in the mounting plate. The plate on all three options in this range measures 60mm x 67mm, with hole centres of 48mm (length) and 38mm (width) — or 38mm on both axes for the inner hole pattern — and a hole diameter of 6mm. This means you will need M6 bolts or equivalent fixings of an appropriate length for your equipment's base material. Before ordering, check that the hole pattern on your equipment matches these dimensions. If your equipment has a different hole pattern, a swivel or fixed castor with a stem fitting may be more appropriate.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"fc-faq-item\"\u003e\n\u003cdiv class=\"fc-faq-q\"\u003eAre these castors suitable for use on hard floors, and will they cause surface damage?\u003c\/div\u003e\n\u003cdiv class=\"fc-faq-a\"\u003eThese castors are fitted with a moulded polypropylene wheel, which is a hard plastic material. They are designed for use on smooth, hard indoor floor surfaces such as concrete, tile, vinyl, and sealed timber. Because polypropylene is a rigid material, these castors are not recommended for use on delicate or sensitive floor surfaces such as unprotected hardwood, luxury vinyl tile, or polished stone, where a softer rubber or polyurethane wheel would be more appropriate to prevent marking or surface damage. On suitable hard floors, the 22mm tread width distributes the load effectively and the wheels roll quietly and smoothly under normal operating conditions.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"fc-note-box\"\u003e* All load ratings stated are per individual castor and apply under normal static indoor conditions on smooth, level floor surfaces. Dynamic loads, floor irregularities, and uneven weight distribution will reduce effective load capacity. Always ensure the selected castor is rated above the calculated per-unit load requirement, with an appropriate safety margin applied.
