square pillow block bearing

Deep groove ball bearing with seals or shields

Single row deep groove ball bearings with seals or shields are particularly versatile, have low friction and are optimized for low noise and low vibration, which enables high rotational speeds. They accommodate radial and axial loads in both directions, are easy to mount, and require less maintenance than many other bearing types. The integral sealing can significantly prolong bearing service life because it keeps lubricant in the bearings and contaminants out.Integral sea

Square pillow block bearings, also known as plummer block bearings, are mounted bearings designed to provide load support for a rotating shaft. They are characterized by their square-shaped housing and are used in a variety of industrial applications where stability and durability are required. Here's a detailed introduction to square pillow block bearings:

Construction and Features

• Housing and Bearing: Square pillow block bearings consist of a housing and an insert bearing. Many pillow blocks have a replaceable bearing, which is referred to as an insert bearing.

• Self-Aligning: The bearings used with pillow block housings are usually self-aligning to compensate for angular misalignments.

• Materials: Pillow block bearings can be made from various materials, including cast iron, stainless steel, and other metals, offering different levels of strength and corrosion resistance.

Types of Bearings Used

• Plain Bearings: These are used for linear applications and operate on a sliding action. They are typically made from materials like bronze, graphite-metal alloys, or plastic and require proper lubrication to reduce wear and friction.

• Ball Bearings: Featuring balls as the rolling element, these provide smooth, low-friction motion in rotary applications.

• Roller Bearings: With rollers as the rolling element, these are designed for smooth, low-friction motion and can handle higher loads than ball bearings.

Applications

Square pillow block bearings are used in applications where a sturdy and reliable support is needed for rotating shafts. They are found in conveyor systems, agricultural machinery, industrial equipment, and any application requiring a robust bearing solution.

Load Capacity and Lifespan

• Load Capacity: Pillow block bearings can handle significant radial and axial loads. The internal structure can be similar to deep groove ball bearings, allowing them to withstand these loads with low working noise.

• Long Life: Designed for harsh environments, these bearings require regular greasing and re-lubrication to ensure long service life. They often come with oil nozzles for convenient re-lubrication.

Sealing Performance

• Sealing: Equipped with heat-resistant and oil-proof rubber sealing rings and steel plate dust covers, these bearings provide excellent sealing performance, preventing the ingress of mud, dust, and moisture, and preventing grease leakage.

Mounting and Shaft Locking

• Mounting: The bearing seat is rigid and integral, preventing deformation during assembly and providing durability under various working conditions.

• Shaft Locking: There are multiple methods to lock the bearing onto the shaft, including set screws, adapter sleeves, locking sleeves, or eccentric sleeves, allowing for easy assembly.

In summary, square pillow block bearings are robust components designed to support rotating shafts in a variety of industrial applications. They offer a combination of high load capacity, durability, and reliability, making them a popular choice for many heavy-duty applications.
