Robust and cost-effective: Radial insert ball bearings and housing units made of cast iron, sheet steel, plastic

Modern housing units are often so similar, it is hard to tell them apart. The same rolling bearing steel or cast iron, similar cages and housing designs, series according to DIN or JIS standards, and so on. However, the differences are apparent upon closer inspection.

Robust and zinc-plated: Our three-piece seal concept

We have developed a unique seal system from three components – an outer cap, seal lip and inner cap, that covers nearly all operating and ambient conditions.

The advantages at a glance:

  • A concentric seal contact surface means that the sealing action and operating life are considerably improved
  • Mechanical protection due to outer caps that extend towards the center of the bearing
  • Zinc-plated inner and outer caps
  • Seal lips for standard applications as well as for operation in high and low temperatures
  • Rolled in sheet steel seals for fixed seal seating and easy relubrication.

Durable and protected against corrosion by corrosion-resistant steel and Corrotect®

Radial insert ball bearings made from corrosion-resistant high-alloy rolling bearing steel are available where high demands are placed on corrosion protection. These are essential if it is anticipated that the bearings will come into contact with foodstuffs.

As a cost-effective alternative to bearings made of corrosion-resistant steels, radial insert ball bearings are available with the Corrotect® special coating.

Flexible and effective: Location methods

You can choose between five location methods for INA radial insert ball bearings. The standard methods are those using eccentric locking collars or grub screws that enable the bearings to be mounted quickly and cost-effectively.

Versatile and cost-effective: INA housing units

Radial insert ball bearings made of corrosion-resistant steel in various types can be combined with

Plummer block housings

  • made of solid cast iron or
  • sheet steel – particularly cost-effective and light, painted or coated with Corrotect®

Flanged housings

  • in two-bolt or four-bolt designs
  • made of plastic – where high demands are placed on hygiene and corrosion protection.

We can supply you with the correct housing unit for practically every application.

The benefits for you are clear:

  • particularly economical – without engineering compromises
  • easy to fit
  • robust and reliable
  • shaft misalignment is prevented by the self-alignment facility.
