Split Pillow Blocks

Split Pillow Blocks

Pillow blocks are versatile mounted assemblies designed for specific industrial applications. They are some of the most used types of mounted bearing systems used to provide shaft support.

Pillow blocks are essentially a special type of bearing system that bolts to a foundation and holds a rotating shaft and inner ring of bearings. They are used to support rotating shafts along with other bearings and accessories.

Split pillow blocks are housed bearing units made of two pieces. A distinctive feature of split pillow blocks is the fact that the bearing housing element can be separated from the base. Split pillow blocks, by design, can be separated for easier bearing replacement, cleaning or lubrication.

Pillow blocks are crucial machinery components that ensure shafts remain in position and operate smoothly. All pillow blocks consist of a mounted bracket (pillow block) that houses a bearing and is often used in low-torque, light load applications. There are two main types of pillow blocks: split and solid.

Solid pillow blocks are made of one solid piece and cannot be disassembled.

Split pillow blocks are the ideal solution for applications and assemblies requiring load support for rotating shafts. They provide maximum protection against impact loads while minimizing radial loading problems associated with other conventional split housings.

The Standard Locknut Difference

Standard Locknut offers a variety of pillow block housing assemblies to address a wide range of industrial applications. Our SAF, SAW and SDAF split pillow block bearing housings have a proven track record in meeting the toughest demands of heavy industry. They allow incorporated bearings to reach their maximum service life with minimal maintenance.

You can choose from different housing variants and seal designs, which eliminates the need for tailored housings and allows for more cost-effective bearing arrangements.

Our split pillow blocks meet FDA and USDA standards and are designed to accommodate a wide variety of spherical roller bearing series and virtually any shaft size (1-5/8” to 30” and larger) while handling extreme loads. They are cast iron and we offer special grades of castings, along with ductile iron and cast steel.
