SBAK Series Pillow Block Bearing Units

SBAK Series Pillow Block Bearing Units
ISUTAMI SBAK pillow block bearing unit is a mounted bearing unit with a one-piece 2-bolt cast iron housing. Each side of the housing has a flange which is reinforced and with a fixing hole on it. The built-in spherical bearing is a kind of rolling ball bearing, usually made of bearing steel, located in the bearing housing. The bottom of the housing is usually divided into solid and hollow types. The insert spherical bearing is mounted with the corresponding bearing case to form a bearing assembly. And the bearing combination can be directly mounted to the mechanism 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 very simple.

SBAK series pillow block bearing units are light duty, with a narrow inner ring and set screw locking to secure the shaft. The inner bore diameter ranges from 20mm to 2 inches. In addition, the SBAK housing is a low shaft height one.

ISUTAMI SBAK 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. SBAK ball 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 better ensure that the grease can be smoothly injected into the bearing from the nozzle.

3. 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.

ISUTAMI SBAK bearing unit can work in harsh environments. The bearing housing is generally compact in 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.
