High-quality metrology for quality control in the measuring room, production, incoming goods and development.
Gear Metering Pumps & Meter Mix Dispense Machines with highest accuracy for processing liquids and pastes.
High-precision rotary stroke bearings for backlash-free linear and rotational movements for use in machine and device construction.
Permissible speeds for the ball cage
Rotational speed calculation:
For rotational movements, the cage rotational speed nK relative to the stationary bearing component is calculated as follows:
Revolving shaft
Revolving guide bush
Standard values for permissible rotational speeds
The maximum permissible rotational speed of a rotary stroke bearing depends on the preload v, the load, the lubrication and the heat dissipation.
The specified values should be regarded as recommended values for rotational movements. In case of a combined linear-rotary movement, the conditions become less favorable depending on the stroke length and stroke frequency, so that the permissible rotational speeds are considerably lower.
For fast linear/rotational movements it is preferable to separate the motions.
