As a direct result of its Quality Function Deployment (QFD) programme, SKF has redesigned its bearing housings to offer greater housing strength, simplified mounting, lubrication and monitoring options.

First off, the SNL series sport cross webs on the base of the housing. These were added to improve heat transfer, allow for higher running speeds and increase the stiffness of the complete structure as well as decrease the surface pressure of the unit. Bosses have also been incorporated in the bearing cap to improve stiffness and provide location points for various accessories.

On the mounting front, the SNL housing has four centre marks for simpler and more precise positioning. Lead-in chamfers between the shaft bore and seal grooves ease fitting and improve seal performance. To assist with maintenance routines, identical markings on both the cap and base elements ensure correct part matching while optional dowel pin locations on the feet simplify re-positioning.

The plummer block has a tapped inlet hole and a grease nipple for grease relubrication. The housing has also been equipped with various dimples for the addition of temperature, load and vibration sensors.
