H-Liner® M

HEF Polymer bushings are the result of intensive research and development in the field of self-lubricated and zero-maintenance bearings. These polymer bushings are of woven structure, and made of PTFE and epoxy resin providing tensile strength that is vastly superior to injection molded polymer bushings – and vastly more resistant to high loads, seizure and galling.

They are well-suited to rotation and oscillation applications, and high-speeds. High-load polymer bushings from HEF are chemically inert, and have low water absorption. Their maximum working temperature range is up to 320°F (160°C).

H-Liner® M products are manufactured with an homogeneous woven sliding polymer, on the complete wall thickness. Mechanical characteristics are similar to brass and don’t require any greasing. They are completely re-machinable and also available as flanged bushings, washers and slides. They are also widely used when low water absorption or misalignment resistance are required.
