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

Raceway machining

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.
