Labyrinth oil seals are standard.
Contamination being the second leading cause of bearing failure requires special attention. Common lip seals were not considered due to their 2,000 hour design life. After wearing out, there will be an open passage way for contamination. For this reason our 3180/85 is provided with labyrinth oil seals as standard. We picked Inpro VBXXD isolators since they are durable, corrosion resistant, and the industry standard labyrinth bearing isolator and provide the best operating environment for the bearing.
