Pillow Block Units
Pillow block units consist of a bearing insert mounted into a housing that is bolt-fixed to a frame or base. They provide radial support for rotating shafts and allow easy replacement of the bearing insert. According to engineering guides, pillow block bearings support rotating shafts and compensate for limited misalignment.

Key Components and Design Features
The Housing ( P Block )
The housing provides protection, stability, and a mounting interface.
| Feature | Material Options | Typical Applications |
| Standard Cast Iron (Gery Cast Iron) | HCT200 / FC200 | General industrial use, medium loads, good shock absorption (UCP series) |
| Ductile Iron (Nodular Cast Iron) | Higher strength and toughness, situable for heavier loads and greater shock resistance. | |
| Pressed Steel / Stamped Housing | Zinc Plated Steel | Ligh-duty applications, lower cost, high cleanliness requirements |
Stainless Steel | SUS304 / SUS316 | Food & beverage, chemical, and wet environments where corrosion resistance is critical |
The Insert Bearing ( UC / UK )
The internal self-aligning bearing element features deep-groove ball bearings with extended inner rings.
| Type | Locking Method | Description |
| UC Series | Set Screw Locking | The inner ring is secured to the shaft using two set scres spaced at 120°. Suitable for moderate speeds and loads, easy to install. (e.g., UCP200) |
| UK Series | Adapter Sleeve Locking | The inner ring has a tapered bore and is mounted onto the shaft using an adapter sleeve. Ideal for applications with high loads, severe vibration, or when a precise, concentric fit is required.(e.g., UKP200) |
| HC Series | Eccentric Locking Collar | Secured with a locking collar that has an eccentric bore. Offers good holding power and is often used in agricultural and textile machinery. (e.g., HCP200) |
Pillow block units, also known as mounted bearing units, provide a reliable and easy-to-install solution for supporting rotating shafts in a wide variety of industrial applications. Made from materials like cast iron, ductile iron, stainless steel, aluminum, or engineering plastics, these units are designed to accommodate different environmental conditions and operational demands.
When selecting a pillow block unit, it's important to consider factors such as shaft diameter, load requirements, locking method, and mounting style. For example,deep-groove ball bearings are ideal for general-purpose applications, while self-aligning bearings are better when there is shaft misalignment.
Proper installation and maintenance are also critical—using the correct fastening torque, ensuring clean mounting surfaces, and applying suitable lubrication all contribute to longer bearing life. Regular inspections and bearing re-lubrication help prevent unexpected downtime.
By choosing high-quality pillow block units with CAD support, reliable materials, and expert engineering advice, you can significantly enhance the performance and longevity of your machinery.
