Sealed spindle bearings combine precision and protection in a compact unit. Integrated sealing discs or labyrinth seals keep the inside of the bearing permanently free of dust, moisture and cooling lubricants – ideal for use in machine tools or packaging systems with demanding environments.
The seals preserve the lubrication over the long term and minimise maintenance requirements, as no regreasing is necessary. At the same time, the high running accuracy and speed capability of the bearings are fully retained.
This design is particularly suitable for applications where cleanliness, durability and reliability are crucial – a plus in operational safety with consistent performance.
