SN series (SN 200, 300, 500, 600) plummer blocks are modular split bearing housings engineered for self-aligning ball bearings and spherical roller bearings with adapter sleeve or cylindrical bore mounting. They deliver high load resistance, optimal grease/oil lubrication, and reliable felt/V-ring sealing for conveyors, fans, pumps, and industrial machinery.
