Both types consist of Nitrile sealing member and a metal case. The case serves as a holder, support and protection for the sealing member and constitutes an effective deflector. The components are not bonded to each other; the Nitrile sealing member is stretched and held in the case by its elasticity. Both the MB-RB and MB-9RB provides a very narrow width. The seal is press fitted on the shaft, and no other means of fixing is required.

Bevel pinion (MB-9RB), supporting bearing for propeller shaft (MB-RB), gear transmission for electric motor (MB-RB) and electric motor (MB-9RB).
