12 best mounted pillow block bearings

Mounted pillow block bearings are a type of bearing assembly commonly used in industrial applications to support rotating shafts and provide them with stability and proper alignment. These bearings are designed to be mounted in a housing, making them suitable for various machinery and equipment. Here's what you should know about mounted pillow block bearings:

Design and Construction: Mounted pillow block bearings consist of two main components: the bearing itself and the housing. The bearing is typically a spherical roller bearing, ball bearing, or tapered roller bearing, depending on the application's requirements. The housing is a sturdy, often cast iron or steel structure that provides a secure enclosure for the bearing.
Support and Alignment: The primary purpose of a pillow block bearing is to support a rotating shaft while allowing it to move freely. The bearing's design allows for self-aligning, which means it can compensate for minor misalignments between the shaft and the housing. This self-aligning capability reduces stress on the bearing and prolongs its lifespan.
Shaft Attachment: Pillow block bearings are typically mounted on the end of a shaft using set screws, locking collars, or other attachment methods. This secure attachment ensures that the bearing stays in place and supports the shaft's rotation.
Variety of Sizes: Pillow block bearings come in various sizes and designs to accommodate different shaft diameters and load capacities. Choosing the right size and type of bearing is crucial to ensure optimal performance and longevity.
Lubrication: Proper lubrication is essential for the smooth operation and longevity of pillow block bearings. Many pillow block bearings have grease fittings or oil ports for easy lubrication maintenance. Regular lubrication helps reduce friction and wear.
Sealing: Pillow block bearings may come with various sealing options to protect against contaminants like dust and moisture. These seals help prevent premature bearing failure by keeping the internal components clean and lubricated.
Applications: Mounted pillow block bearings are widely used in various industries, including manufacturing, agriculture, mining, and material handling.They are commonly found in conveyor systems, agricultural machinery, industrial fans, and more.
Maintenance: Regular inspection and maintenance are crucial to ensure the continued performance of pillow block bearings. This includes checking for signs of wear, maintaining proper lubrication, and replacing bearings when they reach the end of their service life.
Environmental Considerations: When selecting pillow block bearings, it's important to consider the operating environment, including temperature, humidity, and exposure to corrosive substances. Choosing bearings designed for the specific conditions is essential for long-term reliability.
Safety: Proper installation and maintenance of pillow block bearings are essential for safety in industrial settings. A failed bearing can lead to equipment damage, downtime, and potentially hazardous situations. Following manufacturer recommendations and industry best practices is crucial for safety.

Mounted pillow block bearings play a vital role in industrial machinery by supporting rotating shafts and reducing friction. Proper selection, installation, and maintenance of these bearings are essential to ensure the reliability and efficiency of industrial equipment and processes.

UCP205-16 Cast Iron Pillow Block Mounted Bearings-1" Inch Inside Diameter w/Set Screw Loc 2 Packs

FaGoBearing

Based on 79 reviews Check latest price

Product description

The UCP205-16 pillow block mounted bearing with a 1" inside diameter, two bolt holes, and a set screw lock is designed for mounting onto bearing surfaces parallel to the shaft axis, such as conveyor belts. This ready-to-mount unit has a cast iron housing, chrome steel bearings, and is designed for efficient operation at a wide range of speeds. The bearing has a dynamic (radial) load rating of 14 kN and a static (axial) load rating of 7.85 kN. This one-piece pillow block housing allows for a stationary outer ring and rotating inner ring. The bearing is secured to the shaft with set screws to prevent slippage and the housing requires two 3/8" bolts (sold separately). This mounted bearing is used in industrial manufacturing, food and beverage manufacturing, and in the textile industry. Mounted bearings combine a bearing mounted inside a housing unit. The bearing housing replaces the need for a casting or weldment to position the bearing securely for reliable operation, and its design determines the type of insert bearing. Insert bearings use rolling elements (ball, cylindrical, spherical, barrel, needle, spindled, or tapered) to maintain the separation between moving parts to reduce rotational friction, and to support radial and axial loads. Available in a variety of materials and mounting configurations, mounted bearings can be one- or two-piece, they can have an extended inner ring and locking device, and they can have seals and end caps that retain lubrication and protect the working parts of the bearing from environmental debris. Mounted bearings support shafts in a variety of mounting configurations (flange block, hanger, pillow block, and take-up block), and are used in a range of applications from light duty shaft guidance on conveyors to road building equipment and crushers.

Self Alignment Feature: If the bearing is crooked please don't worry. This is our self-alignment feature. These bearing are meant to have some play in them. When you mount them, just use the shaft to rotate the bearing into proper position, or if it is not out of alignment by much, the bearing will correct its own alignment once it begins to rotate. If the bearings were not aligned properly and spinning at high RPMs then sure disaster would happen. Our self-alignment feature is a way to prevent this from happening.

User questions & answers

Question:	The dimensions shown here do not make sense. i.e. - 95mm is not 4 3/4" etc. which one is right? mm or inches
Answer:	I’m not at home to measure the block, but I’d say 4 3/4” is about correct for the overall width, not 95mm.
Question:	What is the max rpm
Answer:	There was no MDS or white paper delivered with the blocks, so I cannot confirm. My application was for a low rpm project. The steel bearing in the pillow block seems to be fairly decent quality, but likely not to exceed 5000 rpm
