Supporting Bearing Holder

- Robust cast housing
- Optimized for stiffness due to internal ribs.
- The supporting bearing permits maximum feed force, minimizes the bending and increases the service life.
- Closed protected construction.

Output pinion

- Gearing quality 5
- Case hardened and ground
- Optional concentricity ≤ 10 µ

The choice of a pinion, which is as small as possible, reduces torque allowing the use of a smaller gear unit.

Mounting Positions

- Any mounting position.

Lubricants and Maintenance

Gear unit:
- Synthetic lubricant CLP HC ISO VG 150
- Lubricated for life
- Maintenance-free

Rack and pinion drive:
- Optionally lubrication with felt gear
- Connection available for central lubrication or lubricator
- Lubrication of the rack and pinion drive must be carried out by the customer.
- For this purpose, we recommend only the use of high quality synthetic oil based grease of NLGI grade 0.

Paint Finish

Black RAL 9005

ME/MEL Motor Adapter

- Fast and easy motor attachment
- Single-part, rugged coupling with expanding function
- Lowest mass moments of inertia for highest dynamics
- Balanced for quiet, vibration-free operation, even at high speed
- Large range of motor shaft diameters
- Error-free thanks to exact centering of the motor
- For reduced backlash, the motor shaft bearing must have a design that is axially backlash-free

Option ServoStop

- Integrated in the motor adapter, electrically released spring-loaded brake.
- When the power is removed, in the event of a power failure or an emergency stop ServoStop will brake both drive and machine shaft safely and reliably.
- Zero-backlash plug-in coupling.
