INPRO labyrinth oil seal description
Description
The INPRO VBXX-D Labyrinth Oil Seal consists of the rotor (1), the stator (2), and the VBX Ring (3).
The rotor (1) fits over the shaft and is held in place by an elastomeric drive ring (4). The drive ring causes
the rotor to turn with the shaft and provides a positive, static seal against the shaft. Since there is no metal-
to-metal contact, there are no friction or wear concerns.
