Robust housings prolong bearing life

05 April 2012

SKF has introduced bearing housings to boost load carrying capacity and exploit the full service life potential of the bearing enclosed by them, improving performance while significantly reducing maintenance and downtime. The new SE housings are constructed from a higher strength cast iron that can accommodate heavier loads. This, coupled with a stiffer, more robust design, also prevents the housing from becoming distorted by over-tightening.

The design of the SE housing also facilitate more reliable lubrication; an effective grease guiding system allows re-lubrication from the side and applies grease directly to the bearing. Meanwhile, improved heat transfer from the bearing outer ring to the support surface reduces the temperature in the bearing, extending relubrication intervals while increasing the service life of the bearing and lubricant. In addition, the improved machining accuracy used in the manufacture of SE housings results in a more accurate bearing seat in the housing, which reduces vibration.

SE bearing housings also offer high resistance to corrosion, providing C3 corrosivity class protection to meet the standards set by ISO 12944, while the environmental impact of SE housings has been declared in an EPD (Environmental Product Declaration) that meets the requirements of ISO 14025.

The new SE bearing housing is an upgrade of the SNL housing series with which it is fully interchangeable. The new SE housing can accommodate a wider choice of bearings and seals, as well as a variety of shaft arrangements and lubrication methods. The upgrade offers a versatile solution for mounted bearing applications and is designed to meet the needs of applications across virtually all industrial and processing sectors.
