Stroke
The strokes S1 (with bellows), S2 (without bellows) and S (with steel cover) are the maximum travel distances between the end stops. Depending on the speed and the moving mass the operating stroke is correspondingly less. The overrun on both sides must be larger than the length of the brake path of the drive. The value of 2 x p (spindle lead) can be considered to be a reliable guideline value. The adjustment of the electrical stroke is the mechanical stroke less 10 mm from each side. This value can be adjusted individually.

the side plate. (Not possible by using carriages with steel cover.) Relubrication intervals depending on operating conditions: 20 - 200 km or after 1 year at the latest.

Linear measuring system The attachment of a direct linear measurement system is possible. The slides with linear motor drive are equipped with a linear measuring system as standard. It is integral with the table. Further information can be found in table 3 on page 7. Motor flange The slides with ball screw drives can be equipped with a motor flange and coupling on request. When ordering please indicate the motor manufacturer, model and type.

Accessories Materials
As standard, the table Components are made of aluminium and are black oxidised. The bottom part of the table is made of untreated aluminium. On request the bottom part and the top part are also available in steel. Limit and reference switches Tables with ball screw drives are fitted with inductive Limit switches PNP/NC as standard and can be equipped with inductive reference switches on request. These are integral with the slide. They are connected via a central plug connection on one of the end Plates (see dimension specifications). Slides with linear motor drive are fitted with 2 limit/reference switches PNP/NC or NPN/NC, which are integrated in the linear measuring system.

Indirect toothed belt drive If space is restricted, an indirect drive using a toothed belt may be the best choice. The motor can be mounted on either the right or left hand side. Standard transmission ratio 1:1.

Linear motor control units and control components The following components are available for controlling the linear Motors: • Dividing electronics for measuring system, integrated in the table • Servo module • Point-to-point or continuous path control Further information available on request or in the offer as submitted.

Permissible operating temperature
Tables with screw drives: -20 °C to +80 °C constant temperature. Linear motor slides: 0 °C to + 55 °C constant temperature.

Cross table assembly Individual tables can be mounted to form a cross table. The standard drill hole patterns of the table top and bottom parts are matched so that mounting of the same or next smaller size is possible. Please note the details in the corresponding column of the dimensional specifications.

Lubrication
The guides and screw are greased with an all-purpose SKF grease by the manufacturing unit. The carriages and the screw nut can be relubricated. For further information please refer to the operating instructions. On the carriages can be fitted with a central lubricating connection. Five lubricating holes are provided in 8
