Bearing unit

Overview:

A bearing unit, also known as a mounted bearing or housed bearing, is a complete assembly that consists of a rolling-element or plain bearing mounted inside a housing. The type of bearing used depends on the specific application’s load capacity, speed, and operating conditions. The housing provides support, protection, and a mounting surface for the bearing, making it easier to install and integrate into various mechanical systems.

Features and benefits:

• Low friction
• Long service life
• Ready to mount
• Low maintenance

Product type and designs:

• Pillow Block Bearing Units- Also known as plummer blocks or pedestal bearings, pillow block bearing units are one of the most common types. They consist of a housing with a flat base and a bearing insert, typically a ball or roller bearing. Pillow block units are easy to mount and provide a secure support for rotating shafts.
• Flange Bearing Units- Flange bearing units, also called flange-mounted bearings, have a housing with a flange that allows them to be bolted directly to a surface or machine frame. They are commonly used in applications where space is limited or a compact design is required.
• Take-Up Bearing Units- Take-up bearing units are designed to provide tension adjustment for conveyor belts and other tensioning applications. They feature a take-up frame that allows the bearing to be adjusted along the shaft to maintain proper tension in the system.
• Cartridge Bearing Units- Cartridge bearing units, also known as cartridge-mounted bearings, consist of a bearing insert pre-assembled into a cartridge housing. The cartridge housing is typically removable, allowing for easy replacement of the bearing insert without disassembling the entire unit.
• Hanger Bearing Units- Hanger bearing units are used to support the shaft from above in applications where a suspended or overhead mounting is required. They consist of a bearing insert and a hanger housing that supports the shaft.
• Flanged Cartridge Bearing Units- Flanged cartridge bearing units combine the features of flange bearings and cartridge bearings. They have a flange for easy mounting and a removable cartridge housing for convenient maintenance.
• Ball Bearing Pillow Blocks- These bearing units use ball bearings as the rolling element and are commonly used in applications with moderate to heavy loads and moderate speeds.
• Roller Bearing Pillow Blocks- Roller bearing pillow blocks use roller bearings, such as cylindrical or spherical roller bearings, for applications with higher load capacities and higher speeds.
• Tapered Roller Bearing Units- Tapered roller bearing units are used for applications with high radial and axial loads, such as in automotive wheel hubs and heavy machinery.
• Plain Bearing Units- Plain bearing units, also known as bushing units, use plain bearings (bushings) instead of rolling-element bearings. They are suitable for low-speed, low-load applications and can handle oscillating or rotary motion.

Applications:

Bearing units simplify the installation process, reduce the risk of misalignment, and provide a compact and efficient solution for supporting rotating shafts or other moving parts in various mechanical systems. Here are examples of applications in which bearing unit might be used:

• Agriculture 
• Mining and construction 
• Food processing machinery 
• Pumps
• Gearboxes 
• Electric motors
