How to install casters with stem

To install plate-mount casters, simply position the caster, mark the mounting holes, and drill them. Then, attach the caster with nuts, bolts, and washers. To install the socket for a stem-mount caster, drill a hole the size of the socket’s outside diameter straight into the bottom of the leg.

Mount the Casters

For easy installation, simply drill the hole into your table leg, apply the threaded insert, and screw in your caster. If you opt for a metal table leg, we can apply/install the threaded insert for you, so all you have to do is apply your caster when it arrives.

When it comes to chairs, bookcases, dressers, or anything else, adding casters makes a huge difference for moving stuff from place to place. Not everything is built at the factory with casters. Fortunately, learning to put casters on anything you want is surprisingly easy.

If your pushing something up against the wall the steering casters need to be on the end that goes up against the wall last. That way you push the front end in and swing the back end in pivoting on the fixed casters.

For heavier loads …

Place the swivel casters at each corner and rigid casters at the halfway point of the longest side. If you place rigid casters that are a little larger than the swivel casters then you will be able to turn your item by balancing on the central casters with the corner casters up off the floor.

4-Wheel Non-Tilt

This cart has four swivels in each corner. A cart with this combination is not for moving in straight lines as it can be hard to maneuver in those instances. You can, however, put swivel locks on the rear skates. By locking the casters, you can move the cargo in a straight line.

Caster Sizes

Most office chairs tend to come standard with 2” to 2.5” wheels. While this is certainly an adequate size, there are some advantages to going with larger wheels and opting for at least a 3” wheel.

If adding a medium sized caster (two inches in diameter), that adds about 2-1/4 inches to the height of your desk. If your desk initially had a height range of 27 to 47 inches, the addition of the caster makes the range 29-1/4 to 49-1/4 inches.

Generally, the greater the weight, the larger the wheel required for the caster. Larger wheels distribute weight and roll more easily over floor obstructions. To determine the load capacity for each caster, divide the combined weight of the equipment and maximum load by the number of casters to be used.

Maintain your casters

For best performance, lubricate your casters every 6 months. Protect wheels — and flooring — with a low-fiber woven chair mat. (Plastic mats are not advisable on top of hardwood flooring, because they tend to trap grit against the floor, which can cause damage.)

Calculating Load Capacity. The first step in figuring out how much each caster must support is to divide the total load by the number of casters. For a 4-wheel material-handling cart that must support 1,000 lbs., for example, dividing 1,000 by 4 gives a minimum load capacity of 250 lbs.

Wheel Load – this is the maximum load that the wheel is designed to carry. The wheel load is determined by taking 50% of the heaviest axle rating of the vehicle (GAWR – gross axle weight rating). Example; if your heaviest axle weight rating is 3000 lbs then your wheel load requirement would be 1500 lbs.

Using 80 pounds, a four caster chair can hold a dynamic load of 320 pounds, but a five caster chair can hold a dynamic load of 400.

Take the total weight of the load and divide this by the number of legs supporting the load. For example, assume a 2,000 pound load is to be supported by 2 legs of a sling. The above will give a total minimum weight on each leg of the sling of 2,000 pounds divided by 2 legs or 1,000 pounds.

The equivalent value of all the loads connected to a system is said to be calculated load. The power rating of loads differs for different applications. When all the loads are considered with the proper multipliers, the calculated load is the final result that provides guidance to calculate various types of load.

Load capacity is the maximum allowable force that can be applied to a stage in a specified direction while meeting stage specifications. This maximum force includes static (mass × gravity) and dynamic forces (mass × acceleration).
