Bearing Systems

Air bearings

In air bearings, a thin cushion of air separates the two bearing surfaces. This allows almost entirely friction-free movement. Two variations exist – dynamic and static bearings. In the case of static air bearings, compressed air is fed to the bearing to maintain an air cushion. Dynamic air bearings generate their own cushion of air as they rotate. The advantages of air bearings include:

  • Simplicity
  • Fastest rotation speed
  • Highest precision
  • Exact concentricity


  • Concentricity meters
  • Drilling
  • Milling
  • Pulverizing

Hydrostatic bearings

Hydrostatic bearings require an external pressure source to constantly force liquid lubricant into chambers between the two bearing surfaces. This creates a fine layer of lubrication that holds the two bearing surfaces apart. Beneficial characteristics of hydrostatic bearing systems include:

  • High axial and radial rigidity
  • Significant cushioning effect
  • Best concentricity
  • Low vibration
  • Consistent bearing qualities
  • No warm-up cycle
  • High durability


  • Turbine bearings
  • Measuring machines
  • Machine tools

Hybrid roller bearings

Our hybrid roller bearings comprise an inner ring, outer ring, ball retainer and ball bearings. They are used for setting spindle shafts, doing so by taking the radial and axial load and facilitating the rotation of the shaft. Through the rotation of the ball bearings between the tempered steel inner and outer rings and the optimum application of a lubricant, friction within the bearing is minimized. Roller bearings offer the following advantages:

  • Widely used
  • High resilience
  • Reliable operation


  • Milling spindles
  • Grinding spindles
  • Any type of rotation
