category of profile

machined or molded/standard/trade product.

 

advantages

as a non-metallic guide element for pistons & rods, for standardised housings, amongst others, according to ISO 10766

  • no seizure due to metal/plastic materials combina
  • medium load-bearing capacity.
  • chamfered profile edges prevent pressing of edge into the corner radii of the housing groove.
  • simple snap-in fitting.

 

application

earth moving equipment, industrial vehicles, agricultural machinery, cranes.

description

with groove on inside diameter, for piston application. split and non split design avail- able.

the guide ring type BWR 07 is mainly used on pistons. it provides guiding and bearing sur- faces between piston and cylinder tube and prevents metal to metal contact between them.

the BWR 07 consists of an extremely abrasion-resistant and low-friction POM-PTFE-Bronze compound and other materials. it can be used for hydraulic oil with a mineral oil base, for water-oil emulsions and for fire-resistant fluids as well as compressed air.

it has a U-shaped cross-section and is split with an angled butt joint. it can be easily expanded for fitting into corresponding installation grooves on the piston. the U- shaped groove arrangement secures the bearing against axial movement.

with groove on outside diameter, for rod application. split and non split design avail- able.

guide ring type BWR 08 is mainly used on piston rods. it provides guiding and bearing surfaces between rod and housing and prevents metal to metal contact between them.

 

the BWR 08  consists of an extremely abrasion-resistant and low-friction POM-PTFE Bronze compound & other material. it can be used for hydraulic oil with a mineral oil base, for water-oil emulsions and for fire-resistant fluids as well as compressed air.

 

it has a U-shaped cross-section and is split with an angled butt joint. it can be spirally compressed inwards for fitting into the rod housing where it springs back out into corresponding installation grooves. the bearing groove arrangement secures it against axial movement.
