What is the use of plummer block?
A pillow block bearing (or plummer block) is a pedestal used to provide support for a rotating shaft with the help of compatible bearings and various accessories. The assembly consists of a mounting block which houses a bearing.
Which bearing is used in plummer block?
High-performance cast iron plummer blocks display excellent rigidity and are easy to handle. They can be fitted with spherical roller bearings (high load capacity) or self-aligning ball bearings. They can be used with bearings with cylindrical bore or bearings with tapered bore with adapters.
How much weight can a pillow block bearing hold?
High Performance: Roller pillow blocks offer dynamic load ratings that range from 800 to 12,500 pounds, and a low coefficient of friction that helps to achieve speeds up to 25 feet/second.
What are three types of mounted bearings?
Types of Mounted Bearings
- Pillow Block (Plummer Block) This is the most common type of mounted unit.
- Flanged Cartridge. These units are usually mounted on vertical surfaces where the shaft passes through a machine frame at a right angle.
- Take-Up Units.
Are pillow block bearings self aligning?

What is UCF bearing?
UCF is square flanged housing with four fixing holes, having a wide inner ring insert Bearings set screw locking and they are re-lubricated. The UCF pillow block (RHP SF and MSF series) consists of a bearing insert with a spherical outer diameter in a cast iron housing.
How do you classify bearings?
Ball bearings are classified according to their bearing ring configurations: deep groove type and angular contact type. Roller bearings on the other hand are classified according to the shape of the rollers: cylindrical, needle, tapered and spherical.
What is a Type E bearing?
Bearings for challenging mounting applications. The PPI Type E pillow block bearing was designed specifically for the challenges of multiple conveyor applications. That’s why our Type E bearing utilizes a double row spherical bearing that makes a misalignment of ± 2 degrees possible.
What is the best lubricant for high speed bearings?
Oil Lubricant: Oil lubricant is generally used for high speed or high-temperature applications that require heat transfer away from working bearing surfaces. The oils consist of either natural mineral oil (with additives that prevent oxidation and rust) or synthetic oil.
