Roller Bearings

Supfina develops and produces solutions for the precise machining of rings and rolling elements.

Solutions for the bearing industry

Highest precision for maximum durability

Roller bearing components must withstand extreme operational requirements – both in terms of dimensional accuracy and surface finish.

With innovative manufacturing solutions such as superfinishing, double-sided grinding, and autonomous machining, Supfina offers decisive advantages for manufacturers of bearing rings and rolling elements – from needle bearings to large-diameter bearings measuring several meters.

The right solution for every type of bearing

  • Deep groove ball bearings
  • Angular contact ball bearings
  • Cylindrical roller bearings
  • Tapered roller bearings
  • Spherical roller bearings
  • Thrust bearings
  • Large bearings for wind power, rail technology, and heavy industry

Superfinishing for bearing rings

Bearing rings require the highest surface quality on raceways, sealing surfaces, and seats.
Superfinishing ensures uniform contact surfaces, reduces friction, improves lubrication, and thus enables durable, high-performance bearings.

Typical workpieces

  • Inner rings
  • Outer rings
  • Raceways

Advantages

  • Optimized surface structure
    for lower noise emissions and reduced wear and tear stemming from reduced friction
  • Flexible automation
    up to fully autonomous manufacturing for maximum efficiency and adaptability to individual production processes: user-friendly process optimization and quick setup for new workpiece types
  • Cost-effectiveness and productivity
    automated loading and unloading systems enable operator-free production with the desired level of autonomy

Autonomous manufacturing of roller bearings

The future of the rolling bearing industry lies in the autonomous operation of production machines.
The Supfina Race Modular system solution enables autonomous and operator-free superfinishing of rolling bearings.

Advantages

  • Minimal personnel costs
  • Maximum process reliability
  • Ideal for 24/7 operation in series or batch production

Superfinishing for rolling elements

Rolling elements are in direct contact with the raceways and must withstand maximum loads. Superfinishing produces a tribologically optimized surface tailored to the specific application in a precise and reproducible way.

Typical components

  • Barrel rollers
  • Cylindrical rollers
  • Tapered rollers

Advantages

  • Improved roundness and dimensional accuracy
  • Increased load-bearing capacity
  • Reduced rolling resistance
  • Long service life even under extreme conditions
