A bearing housing is the most prominent feature of any bearing unit. When a pedestal is used to hold a rotating shaft with a compatible bearing unit consisting of rolling elements and outer and inner raceways, it is famously called a pillow block bearing. Such a housing with mounted bearings are typically used in applications supporting clean environment conditions and lighter loads.

The interchangeability and durability of this bearing is easily possible owing to standardized dimensions, sizes and series and the use of high-quality steel ensuring consistent performance. Where high efficiency and consistency in performance is required, a bearing pillow block is used by having the support surface bolted. For instance, the food and beverage industry and pharmaceutical industry use pillow block with a suitable bearing for greater efficiency in production.

How to Design the Best Plummer Block Bearing?

Where you are looking for the best bearing housing, you need to have the most appropriate bearing and ring washers that hold the rolling elements. Your choice of bearing depends on ball or roller bearings. To make a housing unit, you need either ball or roller bearings, ring raceways and separator. While in operation, the logarithmic profile of the rollers minimizes the friction, thus allowing the machine to operate smoothly.

The roller bearings come in distinctive types such as spherical, cylindrical, needle and tapered. The rolling elements as well are shaped to have crowned-end, conical, spherical, tapered and more. With larger contact area, these bearings can manage heavy loads of either radial or axial or a combined one. By keeping in consideration the above you can buy bearing pillow block for specific applications.

Different Housings of Bearing Pillow Block for Better Performance

Further developments in the bearing technology has offered improved versions of bearing pillow block to suit numerous applications. The most popular ones are:

 Pressed Steel Housing Units: They are more suitable for handling applications of limited loads at low speeds. For the purpose, the bearing is built to have chromium-free steel with zinc coating to save from corroding.

 Cast Iron Housing Units: Offering long service life, these units are built to have lubrication system, where the bearing undergoes lubrication and re-lubrication at regular intervals. The acrylic painted bearing helps prevent corrosion.

You can still go for other choices like composite housings, and so on to have the best selection of bearing pillow block offering better performance.
