SKF SY-3 4FM Pillow Block Bearing

SKF SY3/4FM pillow block bearing is a cast-iron Y-bearing plummer block unit with a 3/4 in (19.05 mm) bore and an eccentric locking collar insert. The grey housing provides rigid support for rotating shafts and a stable mounting surface, while the Y-bearing insert enables secure shaft fixation through the eccentric collar, allowing quick, repeatable alignment and easy maintenance. A grease fitting in the housing allows re-lubrication without disassembly, supporting longer service intervals and reducing downtime. This imperial-size unit is designed for mounted applications where compact, reliable shaft support is needed, and it accepts standard 3/4 in bore SKF inserts compatible with the SY-series footprint. The design enables straightforward replacement of the bearing insert without altering the housing, a common feature in Y-bearing pillow blocks. As part of SKF's line of mounted bearings, SY3/4FM aims to deliver consistent performance in general machinery and conveying equipment where space is limited and dependable shaft support is essential.
