A swivel castor rotates 360° around its vertical axis, enabling multi-directional movement. Fixed castors are typically used in combination with swivel castors to provide both directional control and manoeuvrability on trolleys and carts.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"psc-faq\"\u003e\n\u003cdiv class=\"psc-faq-q\"\u003eIs this castor suitable for use on hard floors such as concrete, tile, or vinyl?\u003c\/div\u003e\n\u003cdiv class=\"psc-faq-a\"\u003eYes. The solid polypropylene wheel performs well on smooth, hard floor surfaces including concrete, ceramic tile, vinyl, and sealed timber. It is not recommended for heavily uneven, soft, or outdoor terrain where a larger or pneumatic wheel would be more appropriate.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"psc-faq\"\u003e\n\u003cdiv class=\"psc-faq-q\"\u003eHow do I calculate the correct number of castors for my application?\u003c\/div\u003e\n\u003cdiv class=\"psc-faq-a\"\u003eFor a standard four-castor configuration, the safe working load is calculated using three castors (not four) to account for uneven floor surfaces and load distribution. With this castor rated at 85kg per unit, a set of four provides a practical working load of up to 255kg. For loads approaching this limit, always apply an appropriate safety factor and seek professional engineering advice.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"psc-faq\"\u003e\n\u003cdiv class=\"psc-faq-q\"\u003eWhat fixings are required to mount this castor?\u003c\/div\u003e\n\u003cdiv class=\"psc-faq-a\"\u003eThis castor uses a bolt on the top side for fixing. The plate measures 60mm x 67mm with hole centres of 48\/38mm and a bolt hole diameter of 6mm. Standard M6 bolts, washers, and locking nuts are suitable for most installations. Ensure the mounting surface is flat, structurally sound, and capable of supporting the intended load before fitting.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"psc-note\"\u003eSold individually.
