Dimensions and maximum loads
Life time of seals
Dimensions and maximum loads
This is the max. total of all loads (acceleration forces and torques, process forces, emergency stops, etc.), which can affect a rotary feed-through, in order to ensure error-free function.
Life time of seals
Life time of seals (with 6 bar pressure); example: DDF-120 SE is driven at a constant 175 RPM in a 3-shift operation (24 hours). Life time of seals: The seals should be replaced after 1,300 hours. (The seal kit is available from SCHUNK)
General notes about the series
Harsh environmental conditions
Please note that use under harsh environmental conditions (e.g. in the coolant area, cast and grinding dust) can considerably reduce the service life of the units, and we will not take over any warranty. However, in many cases we can find a solution. Please contact us for assistance.
Handling weight
is the weight of the total load attached to the flange. When designing, the permissible forces and moments have to be paid attention to. Please note that exceeding the recommended handling weight will shorten the lifespan.
Mounting
Bores and threads for stationary use
Media transmission
Pneumatic and electrical signals
Housing
The housing consists of high-strength, hard-coated aluminum alloy. The functional components are made of hardened steel.
