The housings use Double Row Self Aligning Ball or Spherical Roller Bearings of different series to create units suitable for medium or heavy duty applications.
The various housings can utilise different sealing arrangements to cope with extremes of operating conditions and include, Rubbing Lip Seals, Labyrinth Seals and Taconite Seals. End covers to suit the different types of housings are also available to close off the housing appeture when a bearing is mounted on the end of a shaft.
The Bearing Seat width is machined to allow sufficient room for axial expansion where required. To locate the bearing within the housing one or two Locating Rings are required. To ensure optimum service life from the unit, correct mounting and lubrication is essential.
Pillow blocks with bearings mounted in rigid housings of simple construction are the most common bearing units. They are extensively used for various kinds of transmission equipment and machinery.
Square Flanged Units
These bearing housings have square flange which can be easily attached to a machine with four bolts. With its simple mounting face, this bearing unit is widely used.
Oval Flanged Units
These bearing housings have oval flanges which can be easily installed onto a machine with two bolts. This type of bearing unit is suitable where mounting space is limited or where it is necessary to minimize the distance between shafts. The distance between bolt holes of an oval flange type is generally equal to the distance between bolt holes diagonal position of square flange type.
