Types of Mounted Bearings

     Mounted bearings as a whole are designed to provide support for shaft for shaft driven systems or similar applications. Each bearing is built securely into the frame or housing unit where it can then be mounted for shaft support. The bearings themselves are designed for smooth rotation, reducing friction with lubrication or rolling elements between inner and outer rings.

Split-Housing

Tapped Base

Two piece housing components allow for easy dismantling and access to bearings.

Narrower pedestal width, greatly suited for rotating along the plane of the support structure.

Pillow Block Bearings

Pillow block bearings are extremely common, sharing similarities to the high-load, high performing Plummer block bearings. Pillow Block bearings are primarily designed for light and moderately sized loads for more practical, and less-industrial purposes. Pillow Block units typically houses anti-friction bearings fitted automatically into them, though Split-housing variations allows for more accessible bearing replacement options.

• Housing material consisting primarily of cast-iron or cast-steel
• Rotating shaft is parallel to the mounting surface plane but perpindicular to the pedestal or mounting base.
• Two bolt holes designed in parallel to the shaft, four for heavy-duty variations

Flange Bearings

Contrast to Pillow Block bearings, the Flange bearings are better suited for heavy loads and the shaft is designed perpendicular through mounting plane. Being directly attached to the mounting surfaces grants more surface area to secure the frame without any consequence.

• Primarily cast iron, stainless steel.
• Rotating shaft is perpindicular to the mounting surface plane, through the mounting base.
• Comes with two, three or four bolt variations and styles.

Two-Bolt

Three-Bolt

Four-Bolt

Take-up Bearings

Take-up bearings are applied solely for belt-driven operations, like conveyors, fans or blowers. Take-up refers to a process that maintains belt length to better retain tension over time. These bearings are design to help correct and maintain belt processes, its assembly(built-in bearing), or frame often featuring frame adjustment screws or alternative mechanisms for belt tension.

• Purposed primarily for belt applications.
• Can come in assembly, frame, or the replaceable bearing itself.
• Can be made with elements resistant to corrosive materials found in agricultural/food industry or similar chemically involved operations.

Assembly

Frame

Bearing

Multi-Bearing Housing

These types of bearings are excellent for heavy loads, and high speed operations. Well-suited for supporting fan-like mechanisms via shaft. Multiple pedestals built into a single housing unit provides more surface area to mount and secure the bearings. There are variations that up two or more bearings, to better suit your operational needs.

• Pillow style housing units equiped with self-aligning bearings.
• Useful for more demanding operation requirements.

Two Bearing

Multiple Bearing

     Mounted bearings play a crucial support role in many applications, industrial or practical. The fact that shaft driven technologies are a staple in a wide range of contexts it would be nearly impossible to not rely on a mounted bearing of any iteration. From 3D-printers to motors to conveyors, the context of the application will ultimately decide what type of mounted bearing is required.
