13.3 Technical Information and Alternative Versions

13.3.1 MINISLIDE MS Performance Parameters

13.3.2 MINISLIDE MSQ Performance Parameters

13.3.3 Reference Surfaces and Support Surfaces

The positioning and support surfaces of the carriage and guide rail are designated as follows:

Carriage positioning and support surfaces

Guide rail positioning and support surfaces

MS and MSQ type carriage positioning surfaces and guide rail positioning surfaces

13.3.4 Running Accuracy and Support Surface Parallelism

The tolerance for stroke straightness depends on the length of the guide rail. The table below shows the corresponding maximum values.

Measurements are taken in an unloaded state on a flat surface.

Stroke Straightness (Horizontal and Vertical)

System length L	Straightness
10 – 30 mm	3 μm
40 – 80 mm	4 μm
90 – 130 mm	5 μm

Support Surface Parallelism (Friction-free Table at Center Position)

System length L	Parallelism
10 – 30 mm	12 μm
40 – 80 mm	15 μm
90 – 130 mm	18 μm

13.3.5 Total Height Tolerance

A: ± 0.02 mm, B2: ± 0.02 mm

13.3.6 Push Force and Preload

Push force is affected by preload and the lubricant used. MINISLIDE guideways are delivered as standard with zero backlash and light preload.

Upon request, carriages can be delivered with a defined push force (see section 14.1).

13.3.7 Friction and Smoothness

SCHNEEBERGER attaches great importance to smoothness during the manufacturing process. The accuracy of surfaces and materials has the highest priority. This also applies to the rolling elements used, which must meet the strictest quality requirements. Under normal operating conditions, a friction coefficient of 0.003 can be assumed.

13.3.9 Lubrication

Lubrication is a design element and must therefore be defined during the development phase of the machine or application. If lubrication is only selected after design and construction are complete, according to our experience, this can lead to considerable performance difficulties. Therefore, a well-thought-out lubrication concept is a sign of state-of-the-art and well-designed equipment.

Parameters to consider when selecting a lubricant include:

• Operating conditions (speed, acceleration, stroke, load, installation orientation)
• External influences (temperature, corrosive media or radiation, contamination, humidity, vacuum, cleanroom)
• Subsequent lubrication (cycle time, quantity)
• Compatibility (with other lubricants, corrosion protection and integrated materials such as plastics)

Technical and economic considerations determine the lubricant used.

MINISLIDE Initial Lubrication

MINISLIDE products are lubricated at the factory with Klübersynth GE 46-1200.

MINISLIDE Subsequent Lubrication Intervals

Lubricant should be applied to the guide rail. Subsequent lubrication intervals depend on various influencing variables such as load, working environment, speed, etc., and therefore cannot be calculated. The lubrication area should therefore be monitored over an extended period.

A) Subsequent Lubrication with Oil

For subsequent lubrication with oil, mineral oil CLP (DIN 51517) or HLP (DIN 51524) with a viscosity range between ISO VG32 and ISO VG150, in accordance with DIN 51519, is recommended. During lubrication, the carriage/guide rail should be moved along the entire stroke length to properly distribute the lubricant.

B) Subsequent Lubrication with Grease

For lubrication with grease, grease KP2K or KP1K according to DIN 51825 is recommended. During lubrication, the carriage/guide rail should be moved along the entire stroke length to properly distribute the lubricant.

Custom Lubricants

Special lubricants are used for specific purposes. For example, lubricants for vacuum, cleanroom, high or low temperatures, high speeds or high stroke frequencies. SCHNEEBERGER can supply guideways with the appropriate lubricant for any of these application areas (see section 14.2).
