FAQ
How do I calculate the load capacity needed for my application?
Calculate the total weight of the equipment plus the maximum expected load (contents, people, etc.). Divide by the number of casters used. For example, a trolley weighing 50kg carrying 150kg of goods (total 200kg) with 4 casters needs each caster rated for at least 50kg. Always add a safety margin of 25-30%. If the load is unevenly distributed, size the casters for the heaviest-loaded position. For mobile equipment that moves frequently, choose casters rated for at least 150% of the calculated load.
What is the difference between rubber and PU caster treads?
Rubber treads provide the quietest rolling, best grip on smooth floors, and good shock absorption. They are ideal for indoor use on wood, tile, and laminate floors. PU (polyurethane) treads provide higher load capacity, better wear resistance, and resistance to oil, grease, and chemicals. They are ideal for industrial, workshop, and factory use. Both materials are non-marking. PU treads typically last 2-3 times longer than rubber in industrial applications.
How do I choose between swivel and fixed casters?
Swivel casters rotate 360 degrees for omnidirectional movement and are typically used on the front or steering end of the equipment. Fixed casters roll in a straight line and are typically used on the rear or trailing end. A standard configuration is 2 swivel casters on the front and 2 fixed casters on the rear for easy steering. For maximum maneuverability, use 4 swivel casters. For equipment that only moves in a straight line, all fixed casters may be appropriate.
Can I mount these casters on any surface?
The plate mount casters require a flat, rigid mounting surface with sufficient thickness to support the mounting bolts or screws. Wood surfaces should be at least 15mm thick for light-duty casters and 25mm thick for heavy-duty casters. Metal surfaces should be at least 2mm thick. Use appropriate fasteners: wood screws for wood, machine bolts with nuts and washers for metal, and through bolts for thin materials. Always pre-drill pilot holes to prevent splitting or cracking.
