Deep groove ball bearings

Deep groove ball bearings

Deep groove ball bearings are the most frequently used type of bearings and therefore offer a very good price-performance ratio.
They are easy to assemble, self-retaining and suitable for high to very high speeds.

Deep groove ball bearings are available open and sealed with sealing disks made of metal or plastic.
Bearings sealed on both sides are maintenance-free as they are lubricated or greased for life.

In addition to open or sealed deep groove ball bearings, the following designs are also available:

  • miniature bearings
  • deep groove ball bearings with increased internal clearance
  • nonrusting deep groove ball bearings
  • current-insulated deep groove ball bearings
  • deep groove ball bearings with groove

As deep groove ball bearings are characterised by low-noise running, they are also frequently used in small electric motors for household appliances.

Further typical areas of application include:
engine and pump construction, conveyor technology, fitness equipment, …

Thrust ball bearings

Thrust ball bearings support high axial forces; however, they must not be loaded radially.
Thrust ball bearings consist of shaft washers, housing washers and ball and cage assemblies and are not self-retaining.
For this reason, the ball and cage assembly and the bearing washers can be mounted independently of each other.

Typical areas of application include:
pump and turbine construction, bench drills, machine tools, …

Niro deep groove ball bearings

Niro deep groove ball bearings are ball bearings in stainless steel design.
They are easy to assemble, self-retaining and suitable for high to very high speeds.

Niro deep groove ball bearings are available open and sealed with sealing disks made of metal or plastic.
Bearings sealed on both sides are maintenance-free as they are lubricated or greased for life.

Angular contact ball bearings

Angular contact ball bearings are self-retaining and constructed with a solid outer and inner ring as well as ball and cage assemblies which are made of polyamide as standard, but also of sheet metal or brass cages.
They can be recognized by the offset raceways in the inner and outer ring.
In addition to radial forces, angular contact ball bearings can also support axial forces in one direction and are therefore particularly suitable for applications that require rigid axial guidance.

In addition to open or sealed angular contact ball bearings, the following designs are also available:

  • single row or double row
  • various cage designs

Typical areas of application include:
Drilling machines, wheel bearings, …

Thin section bearings

Thin section bearings are high-precision and low-noise bearings with a very high load-carrying capacity.
They have a very small cross-section in relation to their bore diameter, which allows for the realization of particularly light and compact designs.

Thin section bearings are available open and sealed with sealing disks made of metal or plastic.
Bearings sealed on both sides are maintenance-free as they are lubricated or greased for life.

In addition to open or sealed thin section bearings, the following designs are also available:

  • nonrusting thin section bearings

Miniature ball bearings

Miniature ball bearings are characterized by a particularly small bore with a bore range of 1 – 10 mm.
They are suitable for very high speeds and available open and sealed with sealing disks made of metal or plastic.

Bearings sealed on both sides are maintenance-free as they are lubricated or greased for life.

Typical areas of application include:
Instrument bearings, electromechanical components and applications in medical engineering, …

Self-aligning ball bearings

Self-aligning ball bearings consist of outer rings with hollow spherical raceways, inner rings with cylindrical or tapered bore and ball and cage assemblies. Put simply, two rows of balls share a raceway in the outer ring.
This design allows self-aligning ball bearings to be angularly moved; the inner and outer rings can be “rotated”. In other words, slight misalignments between shaft and housing can be compensated.

In self-aligning ball bearings with a tapered bore in the inner ring, the bearing is held on the shaft by an adapter sleeve.

Self-aligning ball bearings are available open and sealed.

Typical areas of application include:
Paper machines, textile machines, conveyor technology, agricultural machinery, …

Shoulder ball bearings

The design of shoulder ball bearings is similar to that of deep groove ball bearings.
However, they can be dismantled because there is only one shoulder in the outer ring.
Shoulder ball bearings always require a second bearing for counter guidance or must be axially preloaded via the shaft.

Typical areas of application include:
machine tool building, …

Spindle bearings

Spindle bearings are single-row angular contact ball bearings consisting of solid outer and inner rings and ball and cage assemblies with solid window cages.
Spindle bearings have a high manufacturing accuracy and are usually produced with a contact angle of 15 or 25 degrees.

They are particularly suitable for designs that require maximum accuracy and high speed performance.

Typical areas of application include:
machine tool building, …

Insert bearings / Y-bearings

Insert bearings, often also referred to as Y-bearings, consist of a single-row deep groove ball bearing sealed on both sides with a spherical outer surface.
Due to the existing seal, they are protected against many influences such as splash water, dust or dirt.

Insert bearings are often mounted on the shaft with setscrews or eccentric rings.

Further mounting options are:

  • adapter sleeves
  • via a profiled bore

Radial insert ball bearings are particularly easy to assemble and can, with a few exceptions, be relubricated.
