WEAR RING

MATERIAL:

BFT: Bronze filled PTFE compound with Bronze content of 40% (for higher loadbearing 60% BFT is recommended).

MAX.OPERATING CONDITIONS :


Speed : 6 mtrs/sec (+80°C)15 mtrs/sec (20°C)
>BR>TempRange : -50°Cto +200°C

Compressive Strength at Yield : 20 N/m2(23°c)9 N/m2(80°c)

MAX.SURFACE ROUGHNESS :


Static: 3.2 µmRa

Dynamic: 0.4 µmRa

COMPATIBILITY:

Mineral oils, bio oils, water soluble & water glycol fluids.

APPLICATION:

Light to Medium duty hydraulic cylinders.
Suitable for pneumatic cylinders.
High speed.
High temperature resistance.
Dry operation

DETAILS:

The wear rings are supplied usually available in split form. (The split is obliquefor Reciprocating / Oscillating application & straight for rotary). Ifrequired running length’s are also readily available. The BA wear ring is themost widely used general purpose wear ring. The material used is PTFE with a Bronze content of 40%, for further improvement inperformance a Bronze content of 60% can be made available on request. The BA wear ring can be cut to length to suit your specific requirements. Length notonly has to be calculated depending on the Rod/Cylinder bore diameter also considering thermal expansion in the wear ring in operation.

CALCULATION OF LENGTH :

The center line diameter multiplied by p (3.14) gives us the circumference length of wear ring. But allowance for thermal expansion is to be provided. Therefore we reduce the p i.e. 3.14 to 3.13 but to a minimum gap of 1.5 mm for smalldiameters.

FEATURES:

General Purpose.
Stick slip free operation.
Dirt ring to protect piston / rod seal
High temperature resistance.
Improved resistance to high speed cylinders.
Low co-efficient of friction.
Very Economical.
