It has a black rubber tyre on a black polypropylene centre running on a roller bearing, and a rigid zinc-plated pressed steel bracket with a 105 x 87mm top plate that bolts straight to the underside of your equipment. Each castor is rated to 80kg and stands 128mm tall. It suits the fixed end of workshop and tool trolleys, warehouse and stockroom trolleys, machine and equipment stands, and workbenches.\u003c\/p\u003e\u003ch3\u003eWhy it works\u003c\/h3\u003e\u003ch4\u003eBlack rubber tyre – quiet, grippy and hard-wearing\u003c\/h4\u003e\u003cp\u003eThe black rubber tyre (hardness A85) absorbs small bumps, grips well and runs far more quietly than a hard nylon or steel wheel. It copes with temperatures from -20°C to +80°C. Black rubber can leave dark marks on pale or polished floors, so for hospitals, shops and clean areas choose the grey or blue non-marking versions instead.\u003c\/p\u003e\u003ch4\u003eRoller bearing for easier rolling\u003c\/h4\u003e\u003cp\u003eThe wheel runs on a roller bearing rather than a plain bore, so it takes less effort to start and keep moving under load, and it wears more evenly over time.\u003c\/p\u003e\u003ch4\u003eFixed bracket for straight-line tracking\u003c\/h4\u003e\u003cp\u003eA fixed castor does not swivel, so it keeps a trolley running straight and stops the back end drifting. Fitting two fixed castors at one end and two swivel castors at the other gives a trolley that tracks straight but still steers easily. The 105 x 87mm plate has four 8mm holes on 80 x 60mm centres and suits M8 bolts.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eBlack rubber tyre, quiet and hard-wearing\u003c\/li\u003e\n\u003cli\u003eFixed (rigid) bracket, runs straight\u003c\/li\u003e\n\u003cli\u003eRoller bearing, 80kg per castor, 240kg for a set of four\u003c\/li\u003e\n\u003cli\u003e105 x 87mm top plate, M8 fixings\u003c\/li\u003e\n\u003cli\u003e128mm total height\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eWhere it's used\u003c\/h3\u003e\u003cp\u003eThe fixed end of workshop and tool trolleys, warehouse, stockroom and garage trolleys, machine and equipment stands, and workbenches.

Check you have a flat area at least 105 x 87mm under each corner for the plate. For a trolley, pair two of these fixed castors with two 100mm black rubber swivel castors, or the 100mm black rubber total lock castors if it must stay put; all three share the same 128mm height, so the trolley sits level. For the load, add up the weight of the item and everything on it and divide by three rather than four, because on an uneven floor one castor is often lifted; if the answer is over 80kg, choose a larger wheel.\u003c\/p\u003e\u003ch3\u003eInstallation, use and care\u003c\/h3\u003e\u003cp\u003eHold the plate flat against the base and fix it through all four holes with M8 bolts and nuts. Fixings are not included. Line both fixed castors up with the direction of travel so the trolley runs true. Check the fixings after the first few weeks, keep the wheel clear of threads and debris, and wipe clean with a damp cloth. Keep the rubber tyre away from oils and solvents, which can soften rubber.\u003c\/p\u003e\u003ch3\u003eFrequently asked questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWill the black wheel mark my floor?\u003c\/strong\u003e\u003cbr\u003eBlack rubber can leave dark marks on pale or polished floors, especially when turning under load.
