Description

 VIIPLUS offers a standard assortment of plain cylindrical bushings according to ISO 3547 and DIN 1494.Stainless Backed Composite Bushings fabric Supplier.

lubricating Material
Stainless Backed Composite is made out of a stainless steel backing strip (AISI 316TI) covered with PTFE fibresconsisting of multi-filament yarns. The PTFE yarn is woven together with metal
wire to produce a double-sided fabric,with only PTFE fibres on the sliding  surface. The metal side of the fabric is continuously soldered to the stainless steel backing. The PTFE side of the fabric is coated with a thermosetting resin preventing creep of the fabric under heavy loads.
All  Stainless Backed Composite dry sliding bushings can be machined. However, any machining of the sliding surface should be avoided.

Lubrication Bushings
Stainless Backed Composite bushings are completely self-lubricating. The PTFE fibre and the thermosetting resinpermit low friction operation with no lubrication or maintenance. During a brief running-in phase part of the PTFE covering layer is transferred to the mating surface.

Application recommendations:

Shaft tolerance g6 – f7

Housing tolerance H7

Shaft roughness Ra, µm 0 .. 0,4

Shaft hardness, HB 300 – 600
