How To Select Pillow Block Bushing, Flanges, Take Up Units, Mounted Bearings, And Bearing Inserts

Pillow block bushings, self lubricating

Pillow block bearings, flange bearing assemblies, bearing blocks and thrust bearing assemblies consist of a housing with a bearing mounted in it. They are available in various materials, mounting configurations and various bearing properties. Each mounted unit, including the mounted bearing, acts as a system for safely positioning the bearing for reliable operation. Read more about each type of pillow block bearing using the links below.

Pillow Block Bushing

Pillow block bushings, the most commonly used type of mounted units, are designed to provide shaft support where the mounting surface is parallel to the shaft axis. The bolt holes are generally grooved for adjustment during assembly. Pillow blocks are supplied in a variety of configurations. Die-cast pressed steel bearings are also available for light applications.

Pillow block bushings are usually bearing housings with a machined mounting surface that are used in mechanical power transmission systems to support shafts and couplings. The shaft is parallel to the mounting surface and generally perpendicular to the mounting screws. They are a kind of stored storage units. These can have different types of bearings, such as. B. ball bearings, cylinder bearings, tapered rollers or synthetic bushings.

Pillow block bushings are very versatile and can be used in a wide variety of applications. It may vary from shafts supported by single or multiple bearing units. For example:

  • Belt drives that connect motors and pumps
  • Belt conveyor roller,Rotating mills
  • Long shafts connecting motors and industrial gears
  • Ventilation systems
  • Paper machines

Pillow block of roller bearing blocks (also known as Plumber bearing block) bearings are installed and are designed for radial loads acting in the direction of the bearing surface (as opposed to 2-bolts or 4 bolts of the flange of the block).

Pillow Block Bushings are popular bearing housings with inch dimensions, developed as the first choice in terms of design, quality, and economy.

The metric pillow block bushings have integrated lip seals and a removable housing cap. The four-screw ductile iron housing with a single steel bearing insert ensures ready installation. The split housing with removable cover helps with assembly, inspection and maintenance. Integrated lip seals protect against dirt and help retain grease. The closed type pillow block can be greased if required and is suitable for joining or filling a gap.

Assembled bearings combine a bearing that is mounted in a housing unit. The bearing housing replaces the need for a casting or weld to securely position the bearing for reliable operation, and its design determines the type of insert bearing. Insert bearings use rolling elements (ball, cylinder, ball, cylinder, needle, spindle or cone) to maintain the distance between moving parts, to reduce rotational friction and to bear radial and axial loads.

Pillow Block Bushings Type

  • Pillow block bushings can be divided into two types in terms of housing design.
  • Solid and split housings. Bearings in full housings are one-piece housings, and bearings in split housings are two-part housings

Pillow Block Bushings

Select the pillow block bushings type appropriate for your application, i.e. type of load, shaft size, operating speed, misalignment, etc.

Plain bearings,ball-bearing, tapered roller bearings, spherical roller bearings, cylindrical roller bearings
Units can have adjustment screw, eccentric lock, single or double collar, concentric lock or conical adapter
Seals also vary, including gap seals, light contact, heavy contact and auxiliary type seals

With careful consideration of selection, proper installation and good maintenance, bearing bushings can last for years without the need to replace them.

Pillow Block Bushings Feature

  • Easy operation due to full integration with the unit
    Like ball bearings, oilless cushion blocks can be easily attached to the mounting shaft with locking screws. The inner ring provided in the oilless spherical roller bearing bore contributes to excellent friction regardless of the surface roughness of the mounting shaft.
  • Rational self-alignment
    Machined with high precision with a spherical surface processing machine, the contact surface of the oilless ball bearing and the bearing housing allows smooth alignment without making differentiated contact with the sliding surface so that the performance of the bearing is fully demonstrated while absorbs the misalignment of the installation.
  • Maintenance free operation

          Oilless pillow block bushings are suitable for use without the need for lubrication, so they can be used on food processing machines where the use of grease is undesirable, as well as in areas that are                difficult to lubricate without worrying. (Bearing life can be extended if lubricated.)

Pillow Block Bushings Application

Pillow block bushings are very versatile and can be used in a wide variety of applications. It can range from trees supported by one or more bearings. For example:

  • Belt drives that connect motors and pumps
  • Long shafts connecting engines and industrial gearboxes
  • Conveyor roller
  • Rotating mills
  • Ventilation systems
  • Paper machines
