Cylindrical Roller Bearings SKF NU1006

The SKF NU1006 cylindrical roller bearing, as an open idler bearing, can accommodate high radial loads and, thanks to its removable inner ring, allows for flexible installation.

The NU1006 cylindrical roller bearing is a single-row rolling bearing with key dimensions of a 30 mm bore, 55 mm outer diameter and 13 mm width. SKF manufactures this model in an open design without integrated seals, allowing lubricants to reach the raceways unimpeded. A dimensionally stable sheet steel cage guides the cylindrical rollers precisely and maintains a uniform spacing between them. The design offers a high radial load-carrying capacity whilst maintaining compact dimensions.

What loads can the NU1006 cylindrical roller bearing support?

This rolling bearing primarily supports pure radial loads. Due to the line contact between the rollers and raceways, the design can handle higher transverse forces than point-contact ball bearings of a comparable size. As the outer ring has solid flanges whilst the inner ring is flangeless, this design functions as a non-locating bearing. It freely compensates for axial changes in shaft length caused by thermal expansion within the bearing.

When is the NU design the right choice as a non-locating bearing?

The NU design is suitable for applications where the inner and outer rings are to be fitted separately. The inner ring can be removed from both ends, which simplifies fitting into housings and onto shafts. As the bearing is of an open design, protection against contamination is provided by the surrounding housing structure. When designing the system, the standard radial bearing clearance and the permissible operating temperature range of -30 to +150 degrees must be taken into account.
