SAP Series Pillow Block Bearing Units

SAP Series Pillow Block Bearing Units
ISUTAMI SAP pillow block bearing unit is a mounted bearing combined with a one-piece 2-bolt cast iron housing. Each side of the housing has an ear which is reinforced and with a mounting bolt on it. The spherical bearing inside the case is a kind of rolling ball bearing, usually made of bearing steel material. The bottom of the housing is usually solid or hollow types. The bearing combination can be directly mounted to the body of machines by two bolts. It has a self-aligning function, which can be used to replenish grease. The installation and use of this bearing unit is simple.

SAP series pillow block bearing units are light duty, with a narrow inner ring and a set screw lock to secure the shaft. The inner bore diameter ranges from 1/2 inch to 2 inches.

ISUTAMI SAP series bearing units have the following features:

1. Long service life

Spherical ball bearings with housings are usually used in harsh working environments, such as dirt, dust, moisture and high temperatures, and the grease inside the bearing will deteriorate in a short period of time. Therefore, it is necessary to re-lubricate the bearing with a proper time interval and replace the deteriorated grease with fresh grease. SAP bearings are equipped with grease nipples that can be re-lubricated to ensure perfect performance and long life in any working environment. The oil groove on the outer ring can ensure that the grease can be smoothly injected into the bearing from the nozzle.

2.Special heat treatment of the inner ring

The inner ring channel and its surrounding hardened part are normally quenched, the convex of inner ring are high temperature local tempering to maintain toughness and impact resistance. After local high temperature tempering around the inner ring screw holes, the bearing obtains better performance, which prevents the screw from loosening during the running process, and the screw is tightened tightly without causing the inner ring to burst.

3. Unique design to prevent rotation of the outer ring
The outer ring of the bearing is equipped with a unique stop pin that allows the bearing to self-align and prevent the outer ring from rotating, resulting in a longer bearing life.

4. Bearings and housings can be completely interchanged
Bearings and housings are precision machined, bearings and housings are fully interchangeable, and bearings can be easily replaced at any time.

ISUTAMI SAP with spherical outer bearings can work in harsh environments. The bearing housing is generally with tight structure, reliable in sealing, and easy to assemble and disassemble. It is widely applied in agriculture, textile, mining, metallurgy, chemical, transportation machinery and other industries.
