Plastic Bearings

 

          Engineers often hesitate to use Plastic Bearings in their designs, because they have trusted steel bearings for years or they just don't think plastics can handle demanding applications or environments. Plastic Bearings, however, can endure extreme temperatures, heavy loads and high speeds. Some other benefits to Plastic Bearings are listed below.

          Plastic Bearings can often lead to more freedom from maintenance. Their resistance to dirt, dust and chemicals make plastic bearings a set-it-and-forget-it solution. Plastic Bearings can reduce costs up to 25%. They can be highly wear resistance, with a low coefficient of friction and can replace more expensive alternatives in many applications. Plastic Bearings also do not typically need lubrication unless steel balls are used in combination with plastic races. Plastic bearings are designed to maintain a low coefficient of friction over the life of the bearing. Compared to steel bearings, which can become pitted and increase the coefficient of friction, plastic bearings many times last longer. And finally, Plastic Bearings can be used in wash-down applications, salt water and harsh chemicals without compromising

 

            Plastic bearings are available in standard inch and metric sizes. Plastic race bearings can be made in special sizes and types in small and large quantities. Plastic radial ball bearings offer many advantages over standard steel bearings, which include:

1. Corrosion Resistant
2. Design flexibility
3. Bearing & application integration
4. Non magnetic
5. Hygienic
6. Lubrication free
7. Light weight
8. Low inertia- freer turning

 

               SRG manufactures plastic race ball bearing types in single and double row radial, 3- piece thrust, four point contact, thin section, skatewheel ball bearing, insert ball bearing with plastic mounted blocks in either flange or pillow type.

 

               Thermoplastic bearings are readily and inexpensively made from polymers. This allows engineers complete freedom to design the bearing around the device rather than attempting to design the device around a limited range of standard bearings. Thermoplastic ball bearings can be designed with either a pulley, sprocket or a fixing clip to the outer ring. We can mold a hex, spline or the shaft as the inner ring. We can design and build a complete bearing assembly for the ultimate in cost savings. Integrating mating components or mounting features will ease assembly, reduce time, and reduce parts count, thereby lowering your overall cost to manufacture.
