SKF SYNT 50 F pillow block roller bearing unit 50 mm

Application in industrial systems

SKF SYNT 50 F is a pillow block roller bearing unit designed to support rotating shafts with a diameter of 50 mm in demanding industrial applications. This ready to mount bearing unit is factory lubricated and sealed to ensure long service life with minimal maintenance.

The plummer block housing allows installation on a flat support surface, steel structure, wall or ceiling. Thanks to the integrated spherical roller bearing, the unit can compensate for misalignment between shaft and housing. This makes it suitable for conveyors, processing lines, industrial fans, mixers and heavy duty machinery operating under dynamic loads.

Compared to a standard ball bearing arrangement assembled from separate components, this bearing unit provides a compact, pre engineered solution with predictable performance and simplified installation.

Design features and SKF ConCentra locking

The SYNT 50 F unit is equipped with a spherical roller bearing insert with cylindrical bore and the SKF ConCentra locking system. This system enables quick mounting and ensures a true concentric fit on the shaft, reducing vibration and improving stability at higher rotational speeds.

The housing is made of cast iron, providing high rigidity and resistance to mechanical stress. A radial lip seal protects against contamination, while an optional end cover can be used for additional protection. The unit is supplied with grease, grease fitting and relubrication hole, supporting extended service intervals.
