Standardised rolling bearings from norelem are used to a large extent in mechanical engineering and plant construction. With their low friction coefficient and standardised installation conditions, they can be considered for use in various designs and versions for a number of load and bearing related tasks. norelem offers a wide range of the most common types of rolling bearings off the shelf.
Specific dimensions and special versions are available at short notice.
norelem's product range includes deep groove and angular contact ball bearings, self-aligning bearings, cylindrical and tapered roller bearings, as well as axial ball bearings. The correct bearing type not only depends on load type and rotational speed, but especially on such influences as temperature, lubrication, vibration and maintenance requirements as well.
Because of their low frictional torques, especially during the start-up phase, norelem rolling bearings work without significant wear even at lower speeds. Under moderate loads, the grease-lubricated sealed variations are maintenance-free over their entire expected life.
Deep groove ball bearings by norelem accept high radial and axial loads in both directions. They are available in a single row configuration in the 2Z (sealed with two-sided non-contact labyrinth seals) and 2RSR version (sealed with two-sided contacting lip seals) with internal diameters of 3 to 50 mm.
Open single-row angular contact ball bearings by norelem are not only suitable for high speeds but also suitable for high radial and axial loads as well. However, this type of bearing only accepts axial forces in one direction against the shoulder guide. Spherical roller bearings from norelem with a cylindrical hole, however, permit the highest radial and axial loads in both directions. Moreover, they also compensate angular errors.
Cylindrical roller bearings with cage from norelem are the right choice not only for high radial loads but for high speeds as well. These bearings are not self-arresting, which means that the bearing parts can be mounted separately. Single-row tapered roller bearings from norelem are designed for high radial and axial loads, axial loads, yet they only permit axial loads in one direction. Axial ball bearings can handle high axial loads from one direction, but may not be loaded radially.
The tolerance classes of all rolling bearings offered comply with the applicable DIN standards. Rings and balls are made of high quality, fully hardened 100Cr6 chrome steel. Cage materials, depending on the type and version, are either made from sheet steel, polyamide or laminated fabric.
