The rings reduce the risk of metal-to-metal contact and absorb any radial stresses. They can also be used to absorb mechanical vibrations, limit the effects of hydrodynamic press problems and reduce friction to improve piston movement.

REPKOT® is a Repack-S developed material that is a cost-effective alternative to hard guiding materials traditionally used such as bronze, metal coated parts or bimetallic components. It can also be used as a direct substitute for phosphor bronze bearing sleeves and bushes in bush bearings. Other guide ring materials include: Phenolic resin with Graphite filler, and Filled Polyacetal.

Repack-S propose différentes solutions de guidage autolubrifiées permettant de faciliter le mouvement du piston. Nous disposons d'un matériau haute-performance, alternative économique à d'autres matériaux traditionnels résistant à la charge.

The benefits of using REPKOT® include:

  • Self-lubricated, therefore no need for polluting lubricants
  • High compression load resistance
  • High wear and abrasion resistance leading to longer service life
  • Low humidity absorption ensure dimensional stability

 

Other properties:

  • Electrically insulating, vibration insulating
  • Low density
  • Non-toxic
  • Can be machined

 

Specific grades:

  • R2M: filled in MoS2 & PTFE – for use in water
  • R4: filled with Graphite – for use in oil
  • RI5MP: filled with MoS2 & PFTE + PTFE fabric – for dry use
  • Maximum resistance to compressive load: 414 N/mm2.

 

Repack-S propose des solutions de guidage haute-performance permettant de guider le mouvement du piston. Le Repkot est conçu pour être autolubrifié, il réduit ainsi le risque de frottement métal contre métal, il permet de réduire la consommation d'huiles et il est économiquement intéressant en comparaison d'autres matériaux alternatifs résistant à la charge.

Repack-S sealing solutions include a range of proven seal designs: HPX®-Mono®, DANAFLEX®, DANAROTO®, DANAWING®, DANAGLIDE®, DANACAP® and DANASTEP®. All these solutions, when specified properly, offer highly effective, long-lasting and utterly reliable sealing performance.
