The fundamental design of the new Schatz Double V linear bearings from R. A. Rodriguez make them ideal for use in harsh environments. Unlike other systems that allow the ingress of dirt, the rolling elements of these components are enclosed and therefore safeguarded from contamination. As a result they provide a longer service life.

The new Schatz HC™ Series builds on these benefits providing a range of guide wheels and tracks that offer superior performance in demanding aerospace, medical, semiconductor, processing and packaging applications. Careful choice of materials is largely responsible for their longevity.

Most of the corrosion resistant bearings on the market use 440C stainless steel as their preferred material of manufacture. Whilst this steel offers better corrosion resistance than non-stainless bearing materials it is prone to wear. The material composition of the HC™ bearings is unusual in that it ensures both corrosion-resistance and long fatigue life.

The inner and outer rings of the HC™ guide wheels are EMS138 stainless steel as is the linear track whose V section hardened to Rc53 min. Ceramic balls are a standard feature of this range. EMS138 has a fatigue life that is at least five times greater than 440C and shows far greater resistance to oxidation especially in salt spray tests lasting 160 hours.

Four wheel-sizes are available in the standard range. Guide wheels can be mounted vertically or horizontally to suit differing space and application requirements and used to support rotary motion. A range of bushings and ancillary products are available for numerous mounting arrangements.
