ZIMMER Linear
Brakes
Zimmers Linear BRAKES are used
exclusively for DYNAMIC applications. Contact surfaces are made from a
specially formulated brake material similar to automotive brake pads.
They are replaceable and have a
recommended life of 2,000 cycles based on the application. Ideally suited
to prevent un-intended gravity fall of machine motions, compliment an
existing system or in the event of a complete power failure.
Advantages:
Small envelope size with ultra high holding forces
No relative movement
End seals, adapter and distance plates
Controllable and adjustable
High rigidity
Easy to install
Custom models are available upon request
Special friction-coating for brake line material is
proven for industrial applications

The response time of the corresponding valve should be determined from the
respective manufacture, in particular when the valve is employed as a
brake or a safety device against falling.
When employing the PLUS version we recommend pneumatic valves free of
overflow or for example 5/3 way valves (with un-pressurized neutral
position). When valves are used that are not free of overflow, overflow
can occur at the piston seals when they are activated.
Force: [lbf] pound force, [N] Newtons
Note: .2248 [lbf] = 1 [N] or 1 [lbf] = 4.45 N
Displacement: [in.] inches, [m] metres
Note: 39.37 [in.] = 1 [m]
Pressure: [p.s.i.], MPa (mega-Pascals)
Note: 145.04 [p.s.i.] = 1 MPa
Factors that could affect the calculation
Mounting altitude (vertical application)
Lubrication
Temperature
Air pressure supply
Misalignment
Calculation Assumptions
No change in initial velocity when brake is being applied or
responding!
