This split plummer block housing is designed for a shaft diameter of 40 mm and accommodates self-aligning ball bearings or spherical roller bearings, following the DIN 736 to 739 standard for split pillow block housings. The design allows for accurate mounting where shaft misalignment must be accommodated, with the two-piece housing construction (base and cap) simplifying installation and bearing replacement without moving other drivetrain components. The housing is intended exclusively for grease lubrication, with no provision for oil lubrication indicated. This makes it suited for installations where periodic grease relubrication is practical and where sealing arrangements can maintain grease retention within the housing. Dimensionally and constructionally, SN 308 corresponds to SKF SE 308, SKF SNA 308, SKF SNH 308, SKF SNL 308, and Timken SNT 308.
