Learn how self-lubricating Combined Bearings help reduce downtime, eliminate frequent lubrication, and cut maintenance costs. Explore heavy and light series solutions from Kavitsu Bearing. Self-lubricating combined bearings are engineered to bear the radial and axial loads by eliminating the need to have the bearings lubricated manually. These bearings, unlike the traditional bearings, do not need continual greasing since they are produced using modern materials that in itself minimize the friction and wear and tear as they remain in use.
