About SKF Pillow blocks

Pillow block ball bearing unit with extended inner ring and set screw locking, cast iron, Japanese standards

Pillow (plummer) block ball bearing units consist of an insert bearing mounted in a cast iron housing that can be bolted to a support surface. This variant is strong and stiff, and is suitable for applications with both constant and alternating directions of rotation. It has an inner ring extended on both sides and is locked onto the shaft by tightening a set screw on the inner ring, making it easy to mount.

Reliable Performance Across Industries

SKF SNL and SY Series pillow blocks are engineered for versatility and durability, making them an excellent choice for conveyors, pumps, fans, and general industrial machinery. Their robust structure ensures reliable operation even under demanding conditions, providing consistent support and stability.


Effortless Mounting and Alignment

Thanks to the self-aligning mechanism and foot-mounted design, installation is notably simplified. This feature reduces alignment issues, speeding up the setup process and minimizing maintenance interruptions, thereby saving both time and effort for industrial operators.


Advanced Protection and Maintenance

Each housing is finished with a corrosion-resistant paint and fitted with double lip seals, effectively protecting the internal components against contaminants. Grease lubrication ensures smooth operation, extended bearing life, and reduced need for frequent maintenance, making these pillow blocks highly practical in challenging environments.
