The born of the mid-heavy duty casters

Our customers confused: some times, medium duty casters can not meet our loading requirements, but heavy duty casters are too much loading capacity. Can we have another choice?

Some friends may ask the question: which material is better for a caster wheel?

In fact, we cannot say which one is better, different materials have different physical properties, the most suitable material is the best one. If we use casters indoor, we need the caster wheels to be silent, floor protect, non marking, anti slip. Some wheels can meet your need, like elastic rubber wheels, thermoplastic rubber wheels, and Polyurethane wheels. But natural rubber wheels are high cost, recycle rubber will mark on the floor, and smelly. So thermoplastic rubber wheels and PU wheels are widely used in hospitals, laboratories, reading rooms, hotels, living rooms, offices... Some special caster wheels are needed in special working environments, such as: high temperature casters, low temperature casters, anti-static casters, anti rust casters, water proof casters, corrosion resistant casters, noiseless casters, wear resistant casters, extra heavy duty casters...

Strangely, some customers from Europe buy casters with American mounting size, and some times American customers may buy caster wheels with European mounting dimension. So the mounting sizes just mainly fit for some countries, but can be used in the whole world. There are different mounting types for our mid-heavy duty casters, too. You can choose top plate, bolt hole, threaded stem, expansion stem, solid round stem, grip ring stem, and so on. We can also customize and design the casters according to your requirements.
