What are the conditions for choosing a polyurethane caster?

Update:2019-11-09

Caster definitions Casters are a collective term that includes both active and fixed casters. The movable caster is also called the universal wheel. Its structure allows 360 degree rotation. The fixed caster is also called the directional caster. It has no rotating structure and cannot rotate. Usually, the two casters are generally used together. For example, the structure of the trolley is the front two directional wheels, and the rear side is close to the push armrests are two universal wheels.

Nylon (PA) features: high quality nylon core and tread, light weight, low mechanical resistance, flexible rotation, labor-saving manual and mechanical use, equipment used in wet environment, anti-grease, crude oil, salt, some acidic substances, Environmentally friendly materials, normal operating speed of 4km / h. Thermoplastic rubber features: excellent tensile strength, high tensile strength. Long-term temperature resistance over 70 ° C low temperature environment - good performance at 60 ° C, good electrical insulation, anti-slip, resistance Grindability, weatherability and general chemicals.


Site environment used: The working environment contains chemicals, grease, oil, salt and other substances. Special requirements: mute, shock absorption, various special climates such as humidity, high temperature or severe cold. Anti-impact, collision driving safety requirements. Note 1. Avoid overweight. 2. Do not bias. 3, regular maintenance and repair, such as regular oiling, check the screws at the right time.


Thermoplastic polyurethane features: Recycleable thermoplastic polyurethane tire polypropylene copolymer wheel center, ideal for both load and ground protection, low noise, abrasion resistance, impact resistance, spinning grease, mineral oil and some sour The normal running speed is 4km/h. Polypropylene (pp) features: tire core and tread of recyclable polypropylene copolymer, suitable for light weight, heavy duty, easy to operate manually, labor-saving under static load, high cost performance, good chemical resistance, moderate The impact resistance normal operation speed is up to 4km/h.


The casters have castors of various materials, such as cast iron wheels, nylon wheels, and the like. The classification of casters is mainly divided into industrial casters, medical casters, supermarket casters, furniture casters, etc. according to the industry classification. Their difference: medical casters: dedicated casters to meet the hospital's requirements for light weight, flexible steering, large elasticity, special ultra-quiet, wear-resistant, anti-winding and chemical.


Polyvinyl chloride characteristics: Flame retardant is therefore widely used in fire protection applications, and is not easily resistant to acid and alkali corrosion. Has good tensile, bending, compression and impact resistance. According to the load classification: light casters: medium-sized casters with load below 100kg: heavy duty casters in 100-300kg: heavy-duty casters with load capacity of 160-650kg: heavy-duty casters with load above 650-2000kg: load above 1000-6000kg according to installation method Divided into: bottom plate type: including bottom plate type orientation, steering, side brake, double brake, etc. The bottom plate is widely used for testing, and can be welded or assembled with screws to the tooling cart. Various customer choices and replacements.

Casters belong to the general accessories category in hardware. With the continuous development of industry, more and more equipments need to be moved. In order to improve function and utilization, casters have become an indispensable part, which is widely used in factory turnover vehicles and logistics carts. , various tooling vehicles, computer equipment, medical equipment, ship handling equipment, etc.


Supermarket casters: Casters specially developed to meet the mobile needs of supermarket shelves and the need for light and flexible shopping carts. Furniture casters: It is mainly a kind of special rubber wheel which is produced to meet the needs of furniture with low center of gravity and high load bearing. Classified by material: According to the material, it is mainly divided into thermoplastic polyurethane, polypropylene (pp), nylon (PA), thermoplastic rubber, and polyvinyl chloride.


Bolt type: including bolt type steering, side brakes, etc., assembled with screws to the work vehicle, mostly used for light and medium load. Circlip type: including steering and side brakes, mostly used for light and medium loads. Welded pipe type: including steering and side brakes, mostly used for light and medium loads. Bracket material: The material is generally made of carbon steel, which can be used for various plating, such as galvanizing, copper plating, nickel plating, chrome plating, spraying, etc.
