Note: The dimension of t2 for BB25-1K-K, BB25-2K-K and BB25-2GD 1K-K is 0.5 mm shallow compared to DIN 6885. 3. Process the keyway on the shaft 0.5 mm deeply to use DIN standard key. All other models are dimensionally interchangeable with competitors.

Lubrication

Since grease is already applied before delivery, there is no need to apply grease before use.
If the clutch is used with an oil lubricant, the oil lubrication should be applied inside the unit always.
Do not use greases or lubricants with EP additives.
