Oil lubrication 

Oil lubrication 

The advantage of oil lubrication is the flushing effect. The rolling elements are coated with oil, excess oil flows away and any particles are flushed out of the carriage.

Preference should be given to the use of lubricating oils CLP or CGLP to DIN 51517 and HLP to DIN 51524.

At operating temperatures between +10 °C and +80 °C, the viscosity should be between ISO VG 68 and ISO VG 220.

If the temperatures are outside the range stated above, oils with appropriate suitability must be used.

For highly dynamic applications, lubricating oils to ISO VG 100 are recommended.

Compatibility

If it is possible to draw upon practical experience or guidelines from the oil manufacturer, oils must not be used until their behaviour in relation to plastics, elastomers and non-ferrous metals has been tested.

ACHTUNG

The compatibility of oils must always be checked.

This must only be checked under dynamic conditions and at operating temperature.

In case of doubt, the lubricant manufacturer must be consulted.

Miscibility

Oils with a mineral oil base of the same classification are miscible with each other. However, the viscosities should not differ by more than one ISO VG grade.

ACHTUNG

The miscibility of synthetic oils must always be checked. In case of doubt, the lubricant manufacturer must be consulted.

Compatibility with process materials (e. g. cooling lubricants) must be checked.

Lubricant quantities

All the values given are guide values, see tables.

They are valid for the following conditions:

  • operating duration 100%
  • C0/P = 8
  • v = 0,8 m/s
  • stroke 500 mm to 1 000 mm
  • irrespective of mounting positions, 0° to 90°, ➤ Figure.
ACHTUNG

Precise values can only be determined in practice. Adequate provision of lubricant is indicated by a visible, unbroken oil film at the profile of the wipers.

Mounting position
Minimum oil quantity Qmin

The minimum oil quantity Qmin is valid for commissioning or recommissioning after machine downtime of more than 8 hours, see tables.

For initial operation, it is measured such that the oil ducts, rolling elements and raceways will be adequately provided with oil.

Oil impulse quantity Qimp

The oil impulse quantity Qimp is valid if the linear guidance system is connected to a central lubrication system and the stroke ratio is less than 200.

The lubricant quantities are valid for all mounting positions.

If heavy contamination is present, it may be necessary to increase the oil relubrication quantity.

The lubrication impulses must be carried out in direct succession.

ACHTUNG

Carriages with a minimal lubricant quantity metering unit have integral piston distributors. These inject 0,12 cm3 of lubricant per impulse into the carriages. A separate piston distributor cannot be used with these guidance systems.

 

The oil quantity for the damping carriage RUDS is dependent on the size of the recirculating roller guidance system RUE..-E.

Guide values for lubricant quantities

The guide values are valid under the stated conditions, see link.

The functionality of the lubricant quantity metering valve is already integrated in the RUE25-E. The use of a lubricant quantity metering valve is therefore unnecessary in the case of RUE25-E.
