Integrated bearings

Compact and stable bearing designs

Standard bearing designs mostly use conventional bearings. In this case, the standard bearing is positioned between the shaft and the bearing housing. This design of bearing is limited, however in the areas of running speed, lifespan and starting torque. For this reason, bearings designed in this way often need changing on a regular basis.

The integration of the internal raceway in the shaft and the external raceway in the bearing housing mean an extremely compact and stable bearing construction results. This results in a wide range of decisive advantages. The manufacturing tolerances of the integrated bearings are significantly lower than those of the standard bearings. A particularly smooth running, low starting torque and a long service life is achieved - properties that play a central role in critical processes.

Technical advantages

more +
  • A clearly higher load rating with the same dimensions and therefore improved lifespan, and also smaller dimensions with the same load rating
  • The pre-finished solution results in a reduced installation outlay and reduced installation errors
  • No change to the dimensions / shape of the integrated bearing on installation in the housing
  • Reduction in the shape and bearing tolerances in the installation section
  • Possible dimensions:
    - Shaft Ø 4 - 75 mm
    - Outer ring Ø 10 - 100 mm
    - Shaft length up to 600 mm
  • Higher limiting speeds compared with standard roller bearings
  • Low starting torque, easy-gliding, energy saving
  • Application-specific lubrication possible
  • Lifetime lubrication
  • High grease reservoir
  • Relubrication is possible
  • Superior sealing
  • The smaller dimensions of the bearing unit enable housings that are more compact
  • Higher rigidity of the whole system (shaft, housing)

Economic advantages

more +
  • Low cost overall solution possible through integrated bearing unit
  • Reduced purchasing expenditure
  • Longer lifespan
  • Maintenance work and machine downtimes substantially reduced
  • Up to 50% less friction leading to energy savings at the same shaft diameter and the same load rating
