SNH Series
SNH 511

SNH Series is further upgradation in design as compared to previous design of SN and SNA series. The overall size of SNH housing, its mounting dimensions, and center height for bearing bore is maintained uniform with SN and SNA series. It is advantageous that one can readily replace SN and SNA housings with SNH housing. However looking to increasing technical demand in the field, many more features in SNH series are added.

Construction of SNH housing is streamlined with box pattern base and bottom cavity. The hollow bottom base is strengthened with three ribs and one cross rib in the middle. The rib at top of cap is also provided. These features add more strength to SNH series as compared to SN and SNA series.

Inside cavity of SNH is made flat to help more space and smooth movement for oil. Shaft diameter 20 mm to 140 mm for taper bore bearing and 25mm to 160mm for straight bore bearing which is the limiting range for use of suitable bearing for this series.

For located bearing option in axial direction, the provision for locating ring is available. Depending upon bearing size, one or two locating rings are selected.
