The lubrication interval S
• Halve the lubrication interval S
– dusty and dirty environment
– nominal strokes 2000 mm
– speeds 2 m/s
– positioning profile: Z delta operation (frequent acceleration and braking)
– ambient temperatures 40 °C
– product has been in operation for 3 years.
If more than one of the above criteria are met, the normal lubrication interval must be
divided by four.
1. Calculate the load comparison factor fv with
the help of the formula for combined loads
( 12 Technical data) and determine the lub-

2. Lubricate the roller bearing guide at all
lubrication holes aB (permissible oil
accessories).
For checking the cover band:
