Technymon Fritex self-lubricating bushings

Fritex™️ is widely recognized as the gold standard for high performance skid coatings.

Technymon’s Self-Lubricating Bearings


The Fritex-B multilayer bushing (dry sliding bearings) is a three-layer composite product.

  • PTFE fabric with special fibers of 0.40 mm thickness.
  • Special adhesive 60μm thick.
  • Bronze CuSn8P from 0.50 to 2.70 mm thick depending on the bushing size.



The Fritex-B structure best combines the mechanical strength and chemical resistance of bronze and the low friction characteristics of PTFE. The performance without lubricants is as follows

  • Acceptable working surface specific static pressure up to 200 N/mm2
  • Acceptable specific dynamic pressure on the working surface up to 150 N/mm2
  • Maximum sliding speed: 1.5 m/s (300 fpm)
  • Working temperature from: -100°C to +260° C (-148°F to +500°F).
  • Friction factor of 0.03 ÷ 0.15
  • High chemical resistance to industrial fluids and gases. We recommend pre-testing for new application / project.
