3. Calculate the lubrication interval ( t
l
) in hours.
t
1
= t
bl
x K, h
Use the basic lubrication interval (t
bl
) and the load correction factor (K) from step 1 and
step 2 .
4. When the calculated lubrication interval elapses, refill the lubricant reservoir through
the grease fitting.
IMPORTANT The maximum lubricant fill capacity for a roller screw drive is the following:
• 3.0 g of factory recommended lubricant for frame size 83
• 5.0 g of factory recommended lubricant for frame size 110
