Wheel Casters

Casters are all around us and used in our daily lives to make it easier to move heavy or bulky objects. They can be found in a warehouse on rolling warehouse ladders and carts. They can be found in the office on chairs, cabinets and office machines. Casters can be found in industrial shops on heavy machinery, workbenches, storage units and gantry cranes. They are in our workshops on tool chests, mechanic creepers and mobile work surfaces. Casters are even in our homes on dressers, plant caddies, dining room chairs and kitchen carts.

When selecting a caster, several factors should be considered: load requirements, wheel hardness and mounting method, as well as any special application requirements. If you need a caster for a rack that is pushed into a paint oven, then a metal caster would be necessary, while a caster for a mobile hospital cart should be quiet, so elastic rubber or a pneumatic tire would be selected.

Wheel HardnessCaster wheels are made from many different materials: steel, iron, nylon, rubber or plastic. Each material has its own strengths and your selection should be based on the application.

Hard Caster Wheels have a greater load rating than an equal sized soft wheel because they do not compress easily. Hard wheels roll with less effort and are good for light to heavy loads, but they swivel easier under heavy loads. They work well in carpeted areas and hold up to outdoor environments. Hard wheels do not compress or flatten over time so they work especially well for equipment that is not moved often.

Soft Caster Wheels are much quieter than a harder wheel so are best in situations where a quiet operation is necessary. They handle light to medium loads, but swivel best under light loads. Soft wheels work well for hard or uneven surfaces. Soft wheels will flatten over time so should only be used on equipment that is frequently moved. Load CapacityIn order to determine the load capacity for each caster, you must divide the combined weight and maximum load of the equipment by the number of casters to be used.
(Equip Weight + Max Load Weight) / # of Casters = Approx. Load Capacity
Example: unit weight is 100 lbs and max load is 500 lbs. The number of casters that will be used is 4. So the formula is: (100 + 500)/4 = 150 lbs load capacity. Range of MotionCasters are designed to have different ranges of motion. Rigid casters can only move backward or forward. Swivel casters can rotate 360, rolling in any direction. In addition, casters may be constructed with brakes. Brakes stop motion, allowing an object to become stationary. Depending on the caster, a brake may also prevent swiveling.Mounting MethodWe offer three type of mounting methods:
Stem casters have a rod that may or may not be threaded. Threaded studs may be screwed into a t-nut while unthreaded studs are inserted into a pilot hole or caster socket and have a ring or grip neck to hold it in place.
Bolt-hole casters have a hole that allows a bolt to be run through it and secure the caster into place with a nut.
Plate casters have a mounting plate that allows the caster to be bolted or screwed into place.
