SD 3100 Series Bearing Housings

The Bri-Mac SD 3100 Series consists of heavy-duty split plummer block housings designed for spherical roller bearings mounted on adapter sleeves. Developed for demanding industrial applications, the range is widely used in sectors such as mining, quarrying, bulk materials handling, steel production and general heavy industry, where strength, reliability and ease of maintenance are essential.

The SD 3100 Series is available in a choice of material to suit the application and operating environment. The range includes cast steel (SDT), grey cast iron (SD) and spheroidal graphite (ductile) iron (SDD). While all variants provide robust bearing support, the cast steel (SDT) version is the most commonly specified and supplied, offering exceptional strength and
impact resistance for severe-duty applications. The housing design incorporates an integral oil well adjacent to the bearing position, allowing oil-bath lubrication where required. Optional grease points can also be fitted over both the bearing and sealing locations. For blank shaft end arrangements, a steel end cover is supplied as standard. Taconite sealing systems and other design enhancements can be incorporated to suit particularly challenging operating conditions.

For applications requiring maximum rigidity and load-carrying capability,
solid-base versions are also available.
