Why Are Bearing Pillow Block Units Preferred in Most Industrial Applications?

Bearing Pillow Block

Bearing housing supporting the bearing is employed to make the installation of a shaft quick and simple. It is a modular arrangement created to isolate the bearing from impurities while transferring operational dynamic and static stresses.

Bearing housing has a base or plinth that supports a rotating shaft and a bearing unit with rolling components and raceway rings that is compatible with it. It is referred to as a pillow block bearing and accommodates lubrication system and monitoring system parts for improved performance and longer service life. The mountable block is fastened to a support surface before a shaft is inserted to allow for the shaft and inner bearing unit to rotate smoothly.

When it comes to managing both heavier and lighter loads in industrial applications under unfavourable environmental conditions, a bearing pillow block unit is used.

Various Reasons for Using a Pillow Block Bearing

Here are some of the main reasons for using a plummer block bearing:

• A split-bearing pillow block unit is known for long service life and ease of maintenance, as well as the ability to accommodate a preassembled shaft and a monitoring system

• Prevents impurities from getting into the lubricants and bearing unit

• Has a high level of durability, thanks to the premium castings and pressed steel housings used in crafting the bearing

• Greater interchangeability due to the availability of bearing housings in series, dimensions, and sizes that adhere to international standards

Because of its dependability and excellent operational efficiency, a plummer block bearing unit can be found in some specialized industries, including food, beverage, and pharmaceutical.

Get to Know Some Bearing Pillow Block Housing Types

Though a pillow block-bearing unit is customizable, it is available in six common types.

• Split pillow block bearings

• Non-split pillow block bearings

• Flanged housings

• Two-bearing housing units

• Take-up bearing housings

• Roller bearing units

A plummer block bearing that fits the aforementioned classification is designed to meet particular industrial demands for acting loads, speed, environmental conditions, maintenance, and dependability.

How to Design a Suitable Bearing Pillow Block?

With a compatible bearing unit, you can create the best bearing housing. You must choose the type of bearing housing, bearings, and ring raceways based on your application requirements. Roller bearings are designed to have spherical, cylindrical, needle, and tapered rollers with conical, spherical, crowned, and tapered roller ends.

Additionally, the housing unit offers alternatives, including cast iron, thermos-plastic, and pressed steel. A non-split bearing, unlike a split variant, is a single-piece housing. It is an option for strong loads operating in directions opposing the support surface.

Grey cast iron is the most common material used to make bearing pillow block units because it is a standard material that works well for applications requiring good damping, high strength, and thermal conductivity. You can choose the housing constructed with spheroidal graphite cast iron for a higher degree of hardness and strength.
