The main design features of the BT-PNT are the metal 

joint torque transmission together with the rubber bellows. 

This prevents torsional effects on the bellows. The shaft is 

protected across the entire seal length. Easy to assemble, 

the BT-PNT guarantees a long service life due to good 

product turbulence.
