Pillow Block Bearings:
Pillow Block Bearing:
Pillow block bearing units consist of an insert bearing mounted in a housing, which can be bolted to a support surface. The block is mounted to a foundation and a shaft is inserted allowing the inner part of the bearing / shaft to rotate. The inside of the bearing is typically 0.001 inches (0.025 mm) larger than the shaft to ensure a tight fit. Set screws, locking collars, or set collars are commonly used to secure the shaft. Housing material for a pillow block is typically made of cast iron or cast steel.
Pillow block bearings are widely used in varieties of mechanical equipment, especially for conveying agriculture metallurgical, textile and printing machinery, dyeing, foods, building materials, ceramics and so on.
Different types of bearing housings:
1).Pillow blocks – these include UCP, HCP, UCLP, UKP, UCPX, and UKPX.
These mounted bearings are used when support for a rotating shaft axis is required. Their design enables them to support the shaft in operations where the mounting surface is parallel to the shaft axis.
2).Flange type– includes UCF, HCF, UKF, UCFX, UKFX, UCFU, UCFC, UKFC, UCFS, UCFL, UKFL, UCFT.
The flange type bearing housing comes in various shapes and styles such as square, round, and rhombus flange types.
3).Take-up units type – UCT, HCT, and UKT.
These bearing housings have an inner surface which is concave sphered hence the bearing used has a convex sphered outer surface. They are designed to permit moderate initial misplacement. Widely used in conveyor chains and conveyor belts. A sliding slot at the side of the housing facilitates the free movement.
4).Cartridge type – UCC, HCC, and UKC.
This type of bearing housing has a cylindrical outer perimeter hence the bearing outer bore is spherical. The entire unit allows free movement in the axial direction and is self-aligning. This type can be used as free side bearings for long shafts because they are capable of accommodating shaft expansion or contraction due to temperature differences. Also suitable where there is adjustment of the axial direction is required.
5).Light duty types SAFD, SBFD, SAFW, SBFW, SALF, and SBLF.
