Metallic Based Self-lubricating Bushing

TL-HE Bushings

SELF-LUBRICATING PLASTIC BUSHINGS

These bushings manufactured from eslastomic plastic material, homogeneous on the complete wall thickness. Have excellent friction properties and improved wear resistance without external lubrication even on high loads.

 

Applications 

  • Seaway and water treatment bushings
  • Food equipment & drinking water bushings
  • Energy industry: vertical pump bearing ,wagon gates, Butterfly valves, hydro turbines (guide bearing , wicket gate sealing , Operating Ring wear pad, )

 

Product characteristics

TL-HE elastomeric bushing material is made from thermosetting resins synthetic polymers that have performance characteristics superior in compared to other material as casting plastics, brass, rubber or cotton phenolic.... High natural resistance to abrasion and and don't require any greasing

Design operation load

Dynamic working pressure max is  15 Mpa

 

Standard tolerances 

Housing:  H7/H8
Shaft tolerances:  H7/H8

 

Advantages of  TL-HE Bushing

- Maintenance free

- Lower coefficient of friction 

- High resistance to abrasion

- High resistance to shock loading and vibration

- Suitable for dry start up 

Assembly instructions

TL- HE Bushings are best assembled by press fitting, dry ice cooling or by nitrogen mounting. 

For further information, please contact Tobieslager before use.

Available basic forms

Different forms are available with TL-HE Bushing technology: long tube, rod, bushing, molding sheet ,sliding plates,... 

Mating shaft

TL_HE Bushing For optimal performance we recommend to use matting shaft with a final machined mating surface finish of 0.4 to 0.8 micro-metres and hardness higher than 400 HB.
