Set of 4 Extra Heavy Duty Swivel Tool Box Casters with 6 Phenolic Wheels
Set of 4 Extra Heavy Duty Swivel Tool Box Casters with 6 Phenolic Wheels. 6" Diameter x 2" Wide. 4" x 4-1/2" Plate with 3/8 Bolt Holes. Installation Hardware is NOT Included. 4" x 4-1/2" Plate / Holes: 2-5/8"x3-5/8" to 3"x3". HEAVY DUTY CASTER ANATOMY KEY.
Mounting Plate and Kingpin - A flat plate with an Integral Kingpin. Load Bearing (Commercial) - Row of steel balls or rollers that allow the yoke base to swivel. Yoke Assembly - The yoke base with legs welded on and machined for the Main Load Bearings. Axle Bolt - The bolt on which the wheel revolves. Axle Bolt Nut - Secures the axle bolt to the yoke assembly to form the axle.
Thrust Bearing - The row of bearings that operate between the yoke base and the retaining washer. Retaining Washer - Keeps the bearings retained.
Consists of all of the components of the caster as well as a raceway which contains balls or bearings that allow the caster to swivel. RIGID CASTER (aka FIXED WHEEL CASTER).Or stationary caster, or fixed casters consists of all of the components of the caster but does not have a raceway. (It therefore can roll only in two directions, in a straight line). Distance measured horizontally from the center of the step or top plate to the trailing edge of the wheel.
This the distance around which the caster will travel while swiveling and the amount of space needed from the center of the wheel to any obstacles. Width of wheel at the point of contact with the floor.This is not usually the widest point of the wheel or the narrowest point. The widest point is usually on the sidewall and the narrowest is usually at the hub or very center of the wheel. Bearingners are usually inserted to increase the center width of the center of the wheel and decrease the inside diameter of the wheel. For example if you ask about a 6" caster, we assume you are talking about a 6" wheel even thought the caster overall height will be 7" to 7-1/2". Vertical distance from the floor to the top of the mounting plate or the top of the swivel raceway for a stem caster. The working load height of the final item. If the caster has a stem, the overall height does not include the height of the stem. Stops (or slows) the wheel by applying pressure from the side between the wheel and the forks. Not the most positive type brake, but relatively cheap and works in many applications. Bake petal is normally on the side of the caster, but sometimes on the top below the plate or stem mount. Petal engages a pad that clamps down on the wheel for a very positive lock. Since the pad is metal, this brake can be less effective when used with a metal wheel. This brake is sometimes referred to as a Tread Lock Brake. Engaged via a petal that when depressed locks the wheel and the swivel section of the caster. Very positive braking action, but cost more than other types of brakes. 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.
There are many styles and sizes of stems. Plate casters have a small plate with 2, 3, 4 or 6 holes for mounting. Threaded stem casters use nuts and come in several sizes and threading styles.Grip stem casters have solid posts of varying sizes and have a flexible ring to hold the caster in place. Friction stem casters come in a variety of sizes and simply slide into place and use the weight of the chair to keep them in place. The listed capacity is the total for all casters included in the listing. If the listing is for just one caster the total capacity listed is per caster. 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.
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. The ID listed is normally 1/32 smaller than the actual hole size. Hand Trucks and Casters, Inc.Capacity is total for listed quantity. B& P Made in the U.
