SRG bearings engineers are among the most knowledgeable in the industry, and our ability to manufacture on both sides of the globe gives SRG customers a substantial advantage in cost and flexibility.  Our prototype lab, and manufacturing facilities are both geared to fast turn-around, and can accommodate major programs with stringent delivery requirements.

SRG plastic ball bearings open new fields of application for plastic bearings. The inner and outer races are made from high-performance iglide materials. The corrosion-free balls are made from stainless steel. Glass balls are also available for maximum corrosion resistance.plastic ball bearings made from the A500 material are temperature resistant up to 302° F, while those made from the B180 material are designed for temperatures up to 176° F.

SRG specialises in the design and manufacture of [plastic bearings] and assemblies, technical mouldings and associated sub-assemblies that offer many advantages over the traditional steel bearing. Having been at the cutting edge of plastic bearing technology for more than 40 years, the Company's expertise in this specialised field is unrivalled. 

SRG plastic bearings feature in applications as diverse as photocopiers to spa baths, satellite antenna to steering columns and the diversity of our product range increases every year.

Our extensive experience in plastic bearing design and manufacture allows us to use the flexibility of the injection moulding process and the diverse properties of thermoplastics to deliver significant product benefits. These include low friction, corrosion and chemical resistance, reduced weight and inertia, exceptional wear rates and no requirement for lubrication. Our objective is to create innovative products that provide significant benefits to customers and our expertise in plastic fag bearing technology allows us to offer increased functionality and cost reduction through integration and design.

Solid plastic plain bearings are now increasingly popular due to dry-running lubrication-free behavior. Solid polymer plain bearings are low weight, corrosion resistant, and maintenance free. After studies spanning decades, an accurate calculation of the service life of polymer plain bearings is possible today. Designing with solid polymer plain bearings is complicated by the wide range, and non-linearity, of coefficient of thermal expansion. These materials can heat rapidly when used in applications outside the recommended pV limits.

Solid polymer type bearings are limited by the injection molding process. Not all shapes are possible with this process and the shapes which are possible are limited to what is considered good design practice for injection molding. Plastic iko bearings are subject to the same design cautions as all other plastic parts: creep, high thermal expansion, softening (increased wear/reduced life) at elevated temperature, brittle fractures at cold temperatures, swelling due to moisture absorption. While most bearing-grade plastics/polymers are designed to reduce these design cautions, they still exist and should be carefully considered before specifying a solid polymer (plastic) type.
