6. BB, BB-1K and BB-2K Clutches, bearing supported and delivered with grease have dust seal protection
against particles of 0.25mm and over, whereas BB-2GD and BB-2GD-1K clutches, 5mm wider than standard BB series, have special lip seals for effective protection against any dust.
7. The arrow on the inner race shows the direction of inner race engaging.
8. To install the clutch, use a press tool of the appropriate diameter to apply even pressure over the entire face of the inner and outer race.
9. Do not hammer or apply other shock to the clutch.
10. Make sure the housing has enough strength to withstand the pressure required for the press fitting installation of the Clutch.

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