Our S57 desk castor suits timber with a thickness of 19mm. The twin durable nylon 50mm wheels rotate well on carpeted surfaced and the load capacity is 35kg. To calculate the load on each castor the equation would be: The weight of the desk and its contents / the number of castors = the load on each castor providing the weight is distributed evenly. For example 80kg desk / 4 castors = 20kg on each castor. For the same castor with a brake see S57B
