Norelem’s product range includes deep-groove and angular-contact ball bearings,self-aligning bearings, cylindrical and tapered roller bearings and axial ball bearings. The correct bearing type not only depends on load type and rotational speed, but also on influences such as temperature, lubrication, vibration and maintenance.
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 expected lifetime.
Key features and specifications
* Deep-groove ball bearings accept high radial and axial loads in both directions. They are available in a single-row configuration in the 2Z version (sealed with two-sided non-contact labyrinth seals) and the 2RSR version (sealed with two-sided contacting lip seals) with internal diameters of 3–50mm.
* Open single-row angular contact ball bearings are not only suitable for high speeds but also 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 with a cylindrical hole permit the highest radial and axial loads in both directions. They also compensate angular errors.
* Cylindrical roller bearings with cages are suitable for high radial loads and for high speeds. These bearings are not self-arresting, which means that the bearing parts can be mounted separately.
* Single-row tapered roller bearings are designed for high radial and 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.
