SD Series (500,600)
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 involving high loads, elevated temperatures, vibration, and continuous operation. These robust split plummer block housings are specially engineered to provide superior strength, rigidity, and long service life under the most demanding operating conditions.
Compared to conventional SN, SNA, and SNH Series housings, the JAYCO SD Series Bearing Housings feature thicker wall sections, reinforced construction, and enhanced structural stability, making them ideal for industries such as cement plants, steel rolling mills, mining, paper mills, power plants, conveyors, crushers, and material handling systems. The SD Series is suitable for shaft diameters ranging from 125 mm to 450 mm and is widely preferred for heavy industrial machinery requiring reliable bearing support under severe working environments.
