NSK Monocarrier

Compact linear actuator with all-in-one structure for precise guidance and feed movements with minimal design and installation time.
This lightweight, compact linear axis integrates linear guidance, ball screw drive and support bearings in a single unit. K1 lubrication units ensure maintenance-free operation. Black chrome-plated for high corrosion resistance.

Ball castors / pot castors

Effortless movement in all directions...
For smooth movement of heavy loads in a wide variety of environments: bare metal, galvanised or corrosion-resistant material.
- Ball castors for installation: ø 24-36
Compact, smooth-running and ideal for medium load ranges - Pot castors for installation: ø 22-100
Versatile, high load capacity and easy to install - Special pot castors for installation: ø 18-145
Specially designed for customer-specific requirements – also for confined spaces or high loads - Heavy-duty ball castors for installation: ø 20-110
For industrial applications with maximum loads and continuous operation - Spring-loaded ball castors for installation: ø 26-60
For sensitive transport goods or uneven surfaces – absorbs shocks and ensures even load distribution - Ball castor tables

Short-stroke ball guides

Short-stroke ball guides – linear and radial
- Unique combination of high load capacity, precision and low friction
– Sizes ranging from mini versions to heavy machinery
– From clean rooms to dirty environments - Highest precision, backlash-free movements
Guide bushing, ball cage and guide shaft are paired with preload optimised for the application with μm accuracy - High rigidity and load capacity
The large number of balls offers precision and rigidity in all directions - Smooth movement
Precision-machined surfaces minimise friction - Long service life
The guides are virtually wear-free and require very little maintenance. Long, trouble-free operation is guaranteed. - Our service
– We advise you on design and installation
– We develop customised solutions: special designs from 1 piece and in series production
– Large catalogue range available from stock
Precision and reliability
- Linear and rotary movements
- Highest guidance accuracy (radial misalignment 0.5 μm)
- Backlash-free guidance ex works combined with optimum preload
- Low friction (friction coefficient μ = 0.001 possible)
- High load capacity and rigidity (up to 0.005 μm/N)
- Long service life (low maintenance requirements)
- Maximum reliability

ERO round tables

Round tables from ERO-Führungen – compact and precise
For all movement, machining and positioning tasks.
- Long service life
- Smooth movement
- Compact design
- High precision
- TYPE MRT – the manual rotary table
Precise and reliable rotary movements. Made of grey cast iron (standard) or aluminium. With plain bearings or cross roller bearings. Adjustment via micrometre knurling, handwheel or ball crank. Fixation via clamping lever. - TYPE MORTR – the motorised rotary table
Precise and reliable rotary movements. Made of grey cast iron (standard) or aluminium. With cross roller bearing (standard). Motor and coupling flange can be individually adapted. - TYPE DTA – the rotary table
For simple manual turning tasks. Easy to integrate into existing systems thanks to standard mounting holes. Rotary table available in 3 different sizes in aluminium as standard. Mounted with axial plain bearings: simpler version of the MRT manual rotary table.
The external dimensions of the MRT and MORTR rotary tables are identical. Individual special solutions or drilling patterns can be easily implemented.

Dovetail guides

Sled guides with dovetail profile
In S series dovetail guides, the two slide parts (inner and outer) are directly connected to each other, resulting in good vibration damping. In contrast to other slide guides, the large contact surface allows higher loads to be absorbed. The running surface can be coated for better sliding properties. The slide parts are made of grey cast iron (standard) or aluminium.
- Long service life
- Travel speed up to 15 m/min. for coated & lubricated versions
- Easy adjustment of backlash thanks to conical adjustment bar
- Smooth movement
- Excellent vibration damping
- Highest precision
- Economical
- TYPE SO
The two slide parts (inner and outer parts) are the same length. This means that, with their compact dimensions, they are suitable for overflowing or large strokes. - TYPE SE
The two slide parts (inner and outer parts) are of different lengths. Pre-assembled end plates serve as end stops. Scrapers and covers can also be fitted. - TYPE SM
The two slide parts (inner and outer) are of different lengths. The movable slide part can be moved linearly by means of a ground metric spindle. The spindle is available with options such as spindle clamping, position indicator or micrometre knurling.
