Reduce the hidden cost of premature seal and bearing failure

A low-cost seal can become an expensive failure when dirt reaches the bearing, grease becomes contaminated and the machine stops unexpectedly. This COMBI seal targets those root causes with an integrated contamination-control and lubricant-retention concept.

Problems Solved

• Premature bearing wear caused by dirty lubricant.

• Recurring seal replacement in abrasive environments.

• Emergency maintenance caused by contamination ingress.

• Production losses from unplanned equipment downtime.

• Unstable maintenance cycles in outdoor and heavy-duty applications.
