With the wheel and the swivel locked down, the caster becomes a foot with no movement side to side or around. SWIVEL LOCK OR DIRECTION LOCK BRAKE. Usually has a pin that pulls out and when inserted back into the swivel section, prevents the caster from swiveling. This turns a swivel caster into a rigid caster. Normally has 4 positions to lock the swivel at 90 degree offsets.Very useful for some applications and can be combined on some casters with a top lock brake. Also called a "Position Swivel Lock" at times. Another name used for both Friction Lock and Top Lock Brakes when the brake petal is on the side of the caster. Usually refers to a brake that activated from the side and locks only the wheel from the top.
The caster kingpin is the pin in the center of a plate caster that holds the plate to the wheel forks. On a stem caster, the radius is from the trailing edge of the wheel to the center of the mounting stem. The bearing in a swivel caster is located above the wheel at the center of the plate or stem mounting cap.The bearing in a wheel is at the very center of the wheel and can be one of many types. Ball Bearing: uses balls inserted into a housing that allows freedom of movement and usually includes one bearing in the center of two with one located at each side of the wheel, Anular Bearing: uses balls like a ball bearing but has a single piece thats the entire width of the wheel to create a complete solid point of contact for the axle, Delrin Bearing: Nylon or solid poly self lubricating insert that is usually white and acts as a simple and cost effective way to allow freedom of movement without requiring any grease or oil and has no moving parts. The distance from one side to the other side of the wheel at the very center without the bearing installed.
If the listing is for a set of four casters the listed capacity is for the set of four casters. Capacity is the total weight the casters can hold in a static mode.That means the capacity is based on a steady, non-moving, impact free, long-term use. What do the measurements mean?
DIAMETER: This measurement is always about the size of the wheel only. It represents the height or diameter of the wheel from the ground to the top of the wheel only.It is not the measurement of the rig or any other part of the caster. The wheel diameter is precise, however because of the elasticity of rubber there is a variance of up to 1/16 on some wheels. STEM OR PLATE SIZE: This measurement is the mounting mechanism of the caster. This is always the very top part of the rig. If it is a plate caster the size is outside to outside on each side. Since opposite sides are always equal this measurement is provided in 2 sizes i. 4" x 4-1/2" which means two sides are 4" and two sides are 4-1/2" This measurement does not reflect the bolt hole mounting requirements.
See bolt hole dimensions for that size. If it is a stem caster the size is diameter or width of the stem and then the overall height of the stem. The type of threading on a "nut and bolt" style or "threaded stem" is indicated in threads per inch or as UNC which is standard coarse thread or FINE which is tight threading. These are precise measurements within industry standards for all nut and bolt hardware.
TREAD WIDTH: Width of wheel at the point of contact with the floor. This is not the widest point of the wheel or the narrowest point. This measurement is NEVER exact and is almost always smaller than stated. The reason for this is that a rig designed to accept a 1-1/4" wide wheel will be designed for that measurement at the very center and if the wheel is also 1-1/4" wide at the point of contact with the floor it would rub against the sidewall of the rig and fail to roll. Tread width is always narrower than stated to allow the wheel to roll.This is the industry standard for this measurement. CASTER SIZE: Determined by wheel diameter. For example, if you ask about a 6" caster, we assume you are talking about a 6" wheel even though the caster overall height will be 7" to 7-1/2". So, when you start to search for a caster be aware that a caster listed as 6" x 2" is specifically talking about the size of the wheel and the 2 measurement is for the center of the wheel not the edge of the wheel. OVERALL HEIGHT: Vertical distance from the floor to the top of the mounting plate or the top of the swivel raceway for a stem caster.
ID or BEARING SIZE: This measurement is the inner diameter of the wheel and is not precise. In fact, the size listed is the size of the bolt required that will go through the center of the wheel. The ID or bearing size is slightly larger than the bolt to allow the bolt to easily insert into the wheel and create a low-friction environment for the wheel to turn.
