Split Plummer Block Housings SNS

For shaft diameters of 115 mm to 530 mm and 4 7/16 inch to 19 1/2 inch

Plummer block housings SNS represent a completely new generation of large size housings. Through the systematic further development of the proven FAG plummer block housings, Schaeffler can offer even greater efficiency and cost-effectiveness for machinery and plant. The unique housing design gives an increase in the life of the spherical roller bearings fitted in the housing of up to 50%. This is achieved through optimised load distribution in the bearing that occurs due to the interaction of the bearing and housing geometry under load.

The most important advantages of the newly developed plummer block housings SNS can be summarised as follows: - Longer bearing life due to the innovative housing design. This gives lower maintenance and downtime costs of the entire machine or plant; - Increased strength and shock resistance due to the use of spheroidal graphite cast iron as standard. The highly robust housings are ideally suitable for aggressive environmental conditions such as those in mining applications; - Different sealing variants allowing matching to an environment with particularly harsh contaminant and dust conditions; - Optimum lubricant supply to the bearing independent of the bearing position by means of a special lubrication groove in the interior of the upper housing section and through grease outlet holes in the lower housing section; - Design with good anti-corrosion characteristics and reduced cleaning requirements due to inclined run-off areas as well as a projecting upper housing section; - Indentations indicating the shaft and bearing centre, ensuring rapid and simple alignment of the housing: - Machined locating surfaces on the housing base, allowing precise alignment of the housing; - Serial numbering on both halves of the housing, ensuring their correction allocation. This prevents incorrect transposition between the pairs of upper and lower housing sections; - Prepared mounting points allowing immediate use of Condition Monitoring.
