Significance of Bearing Pillow Block in Industrial Applications

 

Bearing Pillow Block

If a rotating shaft is supported using a pedestal with compatible bearings and inner and outer rings, it is called a bearing housing or a pillow block bearing. The housing has bearings mounted on it and it is used in applications that do not support higher loads and operate in a cleaner environment. The pillow block bearing comes in standard sizes and dimensions and they are crafted using high-quality steel to help perform consistently. 

Such bearing designs with mounted bearings are generally meant to help the rotating shaft with load support and are used in applications that demand a clean environment and lighter loads. By bolting to the support surface, you can have the bearing pillow block used in applications that ask for high-performance bearing solutions mostly food and beverage industry. Nevertheless, it is essential to choose the appropriate bearing unit for high efficiency and durability.

How to Have the Most Suitable Pillow Block Bearing?

Using the right bearings in the unit in-between the inner and outer raceways makes the best bearing housing. When it comes to choosing the bearing, you have the ball bearings, as well as roller bearings. The rolling elements in the shape of balls, along with the raceways, are used to design a housing unit. You also have a ball separator. The roller bearings, on the other hand, have cylindrical rollers as rolling elements.

These rolling elements, either balls or rollers, help reduce friction while operating smoothly. The rollers generally come in various types such as cylindrical rollers, spherical rollers, and tapered rollers. These rollers are conical, spherical, and crowned-end ones. Roller bearings have greater contact area and hence, they can accommodate heavy loads, either radial or axial loads or a combination of both.

 

You can buy pillow block bearing to suit the application by taking into consideration the speed and load capacity.

Some Common Variations in Bearing Pillow Block Design

A pillow block is available in different housing materials using advanced technology. With different applications demanding high-performance bearing pillow block units, their housing material comes in the following variants:

• Cast Iron Housings: Most applications find them suitable and they have lubricant filled for re-lubrication offering extended service life. They are painted using acrylic paint to prevent corrosion.

• Pressed Steel Housings: Made of chromium-free steel, the housing is zinc coated to protect it from corroding. They help operate at low speeds carrying limited loads. The lightweight housing needs seating rings in rubber to dampen vibration.

• Composite Housings: Suitable for applications of high speeds, this housing is made of glass fiber, which is of reinforced PA6 material and lightweight. 

Keeping in mind the above information, you can easily find the right bearing pillow block for your applications.
