Get To Know More About Bearing Pillow Block Units

Bearing Pillow Block

A pedestal to offer a support to a rotating shaft, a pillow block bearing, also known as a plummer block bearing unit, consists of a bearing housed in a mounting block, which is fixed on a support surface using bolts. The compatible bearing and other components like ring raceways allow the shaft to rotate. The bearing is so designed that its inner part fits tightly to hold the shaft. The set collars and screws help secure the rotating shaft.

With a pillow block bearing unit, you get to have a housing with an anti-friction bearing mounted in it. Unlike the typical flange units, the shaft mounted here is parallel to the mounting surface and vertical to the mounting holes. The compatible bearing can be of any type like spherical, cylindrical or tapered, which comes with specific rollers and ring raceways, both inner and outer. The mounted bearing housing unit is generally found in applications that ask for lighter loads and cleaner environment.

What Makes the Best Pillow Block Bearing Design?

The bearing pillow block unit type is identified by the type of bearing used. Henceforth, if you want to have the best and most appropriate plummer block bearing unit, you need to choose the best bearing and ring washer types. By choosing roller bearings, you can ensure a high operational reliability owing to the logarithmic profiles of the rolling elements, which form a hydrodynamic lubricant film.

The design helps you have the bearing mounted safely with the inner ring rotating and outer ring staying stable. The bearing unit while in operation remains safe for it is bolted using the holes on it to the foundation. The plummer block bearing comes in either solid or split type. When the solid type is made of a single-piece of housing, the split type comes in two types with a detachable cap and base.

Improved Design Variants of Housings of Bearing Pillow Block

Where applications demand meeting certain conditions, the bearing pillow block is used with some variations in designs. The most important ones are:

Pressed Steel Bearing Housing Units: The unit is made using chromium-free steel and is zinc coated to not to have corroding. They are best used for limited load applications operating at low speeds.

Cast Iron Bearing Housing Units: They come with the lubrication system and are acrylic painted to avoid corrosion.
