Swivel & Rigid Castor Wheels

The castor consisted a lot of components will be have to function simultaneously for a full operation. The components of the Swivel Wheels are the wheel, the axle, mounting plate, upper and lower ball races, wheel bearings, and roller bearings. A Swivel Wheel and a normal wheel are the factor determining the existence of the yoke. A wheel and a castor yoke to be assembled to become a castor. The part of the most importance of a castor in engaging the mechanism is the yoke. It is a gadget with 2 “legs” protruding outward, much like the blades of a pair of scissors, although in the case of the yoke they do not meet at a connecting point.

These two “legs” are case hardened vertical extensions of a piece of horizontal metal. The yoke can also be a piece of single formed steel with two case hardened “legs” welded to each side. The wheel is inserted between these legs and is secured by the axle which is passed through the outside of one part of the yoke, through the axle hole of the wheel, through the wheel bore, and finally through the axle hole of the opposite yoke. Often, the mechanism is fastened with a hex head bolt and hex nut.

The caster yoke of the Swivel Wheels also assists both the top and bottom raceways. The upper and lower raceways refer to ball bearings that race between two formed pieces of steel thereby aiding the castor to swivel.

The mounting plate that is the connection point between the castor and the piece of trolley or furniture is fixed onto the yoke.

The two fundamental types of yokes determine a primary distinction between casters-the Swivel Wheels castors and rigid wheels castors. Swivel Wheels casters come attached with a swivel yoke. They allow the fork legs and the attached wheel to rotate 360 giving total freedom of movement. The other is the rigid caster that provides zero freedom of movement. Their swivel partners are not as firm as they are as rigid castors have a strict bi-directional movement that is important for stability. While Swivel Wheels casters allow freedom of movement along those tricky corners and areas, they have an inclination to sometimes head in a direction other than the decided direction.

The most important to check the yoke, axle, the hex head bolt and hex nut holding the Swivel Wheels casters in place at the time servicing and routine check of material handling equipment. If the wheel axle is lose that causing injury and accident.
