SD Series (3000,3100,3200)
SD Series Bearing Housings Manufacturer
Extra-Heavy Duty Split Plummer Block Housings for Severe Industrial Applications
JAYCO Engineering manufactures SD Series Bearing Housings designed for extra-heavy-duty industrial applications where high loads, severe vibration, elevated temperatures, and continuous operation demand maximum reliability and structural strength. These heavy-duty split plummer block housings are engineered with reinforced wall sections and robust construction to deliver long service life in harsh industrial environments.
Compared to conventional SN, SNA, and SNH Series housings, the JAYCO SD Series Bearing Housings offer superior rigidity, enhanced load-carrying capacity, and improved operational stability, making them ideal for cement plants, steel rolling mills, mining industries, power plants, paper mills, conveyors, crushers, and material handling systems. The SD Series is recommended for shaft diameters ranging from 150 mm to 450 mm and is widely used in heavy industrial machinery operating under severe duty conditions.
