Brake cylinders, general

BPW Brake cylinder
BPW Brake cylinders come with a range of special
features justifying their high quality level:

The cylinder size and the part number are
embossed on the unit
Parts which are critical to function can be
traced back through the QA system by
means of their type plate data
The extended compressed air connection
makes them easy to install
Double seals on the twin compartment

Effective anti-corrosion protection by powder
and Delta Tone coating
Shot-peened, epoxy-coated compression
springs
Spring-type accumulator chamber in
permanent, positive connection
Long service life thanks to high-performance
rubber diaphragms
Closely sealing bellows
Chromated aluminium housing

Types:
Diaphragm cylinders
These act as a service brake and are characterised by
their compact external dimensions and low weight.

Diaphragm-diaphragm cylinders ( M - M )
These act both as a service brake and an auxiliary and
parking brake. They are lighter than the diaphragm-piston
cylinder.

Diaphragm-piston cylinders ( M - K )
These have the same function as a diaphragm-diaphragm
cylinder.
Their greater spring accumulator force means they are
particularly suitable for vehicles with higher axle loads.
