Set of 4 Heavy Duty Swivel Casters with Poly on Aluminum 8 x 2 Wheels
Set of 4 Heavy Duty Swivel Casters with Poly on Aluminum 8" x 2" Wheels. 4" x 4-1/2" Plate with 3/8 Bolt Holes. Installation Hardware is NOT Included. A caster represents the complete assembly of one wheel, wheel bearings, yoke, axle, and nut, and optional: thread guards, brakes, swivel locks, springs... , all of which are assembled together as one complete unit.There are two basic types of casters. SWIVEL CASTER (aka CRAZY WHEEL CASTER). 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.
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. HUB WIDTH: Distance measured at the very center of the wheel. This size is always larger that the wheel or tread width to prevent the wheel from rubbing against the sidewall of the rig. 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. 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.
