At 122mm total height and with an 83mm swivel radius, it is designed for applications where greater ground clearance and a wider turning arc are required. The 85kg individual load rating — giving a combined set capacity of 255kg — makes it the most capable option for heavier light-duty loads.

This makes it ideal for applications where a compact, low-profile fixing is needed and where drilling a single hole is more practical than fitting a four-hole top plate. Top plate castors, by contrast, are secured using four bolts through a flat mounting plate, which distributes load across a wider area and is better suited to heavier-duty applications. Bolt hole castors are commonly used in shop fitting, light furniture, and display equipment.\u003c\/div\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"ldc-faq-item\"\u003e\n    \u003cdiv class=\"ldc-faq-q\"\u003eWhich size should I choose — 50mm, 75mm, or 100mm?\u003c\/div\u003e\n    \u003cdiv class=\"ldc-faq-a\"\u003eThe right size depends on two main factors: the total height you need and the load you are carrying. The 50mm castor gives a total height of 72mm and is rated to 65kg per castor — best for compact, low-profile applications. The 75mm castor stands 100mm tall with a 75kg rating, offering a good balance for mid-range furniture and equipment. The 100mm castor reaches 122mm in height and carries up to 85kg per castor, making it the best choice for larger or heavier items. As a general rule, a larger wheel also rolls more smoothly over minor floor irregularities.\u003c\/div\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"ldc-faq-item\"\u003e\n    \u003cdiv class=\"ldc-faq-q\"\u003eAre these castors suitable for use on hard floors?\u003c\/div\u003e\n    \u003cdiv class=\"ldc-faq-a\"\u003eYes. The black polypropylene wheel is designed for use on hard indoor floor surfaces such as concrete, tile, vinyl, laminate, and timber. Polypropylene is a hard-wearing plastic that rolls efficiently on smooth and semi-smooth surfaces. It is not recommended for use on soft flooring such as carpet, as the hard wheel may cause indentation or resistance. For carpeted environments, a softer rubber or polyurethane wheel would be more appropriate.\u003c\/div\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"ldc-faq-item\"\u003e\n    \u003cdiv class=\"ldc-faq-q\"\u003eHow do I calculate the correct load capacity for my application?\u003c\/div\u003e\n    \u003cdiv class=\"ldc-faq-a\"\u003eTo calculate the required load capacity, take the total loaded weight of your equipment (including any contents) and divide it by the number of castors you are fitting. For example, if your unit weighs 200kg fully loaded and you are fitting 4 castors, each castor must support at least 50kg. Always select a castor with a rated capacity above this figure to allow for a safety margin and to account for uneven load distribution during movement. The 50mm castor supports up to 195kg across a set of 4, the 75mm up to 225kg, and the 100mm up to 255kg.\u003c\/div\u003e\n  \u003c\/div\u003e\n\u003c\/div\u003e\n\n\u003c!-- NOTE BOX --\u003e\n\u003cdiv class=\"ldc-note-box\"\u003eAll castors are dispatched from UK stock.
