Wheel material selection for caster bushings Heavy duty casters are used for heavy equipment movement, so the wheels of heavy duty casters typically use a hard tread single wheel. Such as nylon wheels, cast iron wheels, forged steel wheels, hard rubber wheels, polyurethane wheels, and phenolic resin wheels are ideal choices. Among them, forged steel wheels and polyurethane caster wheels are especially suitable for the wheels of extra heavy duty casters.
The wheel diameter of the heavy-duty casters is selected. The caster bushings are based on the diameter of the wheels. The more flexible the principle is, the common specifications are 4 inch casters, 5 inch casters, 6 inch casters, 8 inch casters, 10 inch casters, 12 inch casters, Extra heavy duty castors are available with 16" and 18" wheels. At present, our 12-ton heavy-duty casters are double-wheel casters with a diameter of 400mm and a wheel width of 125mm. Of course, special-sized heavy-duty can also be customized, for example, low-weight heavy-duty casters, small 2-inch casters, and can carry more than 360kg.
Usually choose the appropriate wheel carrier first consider the weight carried by the casters, such as supermarkets, schools, hospitals, office buildings, hotels, etc., because the floor is good, smooth and the goods are light, (each caster is carried at 10-140kg), suitable The electroplated wheel frame stamped and formed by thin steel plate (2-4mm) is light in weight, flexible in operation, quiet and beautiful. The electroplated wheel frame is divided into double row beads and single row beads according to the ball arrangement. Apply double rows of beads if moving or handling.
a caster body; a wheel set is disposed on the pivot seat of the caster body, the wheel set comprises a combination of a wheel, a shaft, a sealing body and a cover, the caster body is provided with a barrel seat at the front, and the bottom of the caster body a recessed groove is formed in the recess, and a groove is recessed in a front end of the base of the caster body, and a fitting groove is arranged on both sides of the groove;
If it is used to carry heavy objects such as textile factories, automobile factories, machinery factories, etc., due to the heavy load and long walking distance in the factory (each caster is carried at 350-1200kg), it should be cut with thick steel plate (8-12mm). After welding the wheel frame, the movable wheel frame uses flat ball bearings and ball bearings on the bottom plate, so that the casters can withstand heavy loads, flexible rotation and impact resistance.
The brake system is disposed in the concave surface of the bottom of the caster body, and the brake system comprises a combination of a brake spring, a lower brake knob and a push brake knob; the fixed system is disposed on the concave surface of the bottom of the caster body, the orientation The system comprises a combination of a positioning card, a foot pedal and a composite plate; the steering gear plate is arranged above the tooth plate of the brake system of the brake system, and the tooth plate is integrally formed with the brake spring, so that the tooth plate is simultaneously displaced upward The occlusal steering sprocket forms a snap fit, so that the caster can simultaneously achieve the purpose of braking and steering.
