Pillow Blocks, Stamped Type, Insert Bearing, Diamond Shaped

Economical Pillow Block Bearing Stamped Type Diamond Flange Pillow Block Bearing
Pillow block bearings (hereinafter referred to as bearing units) are assembly products consisting of grease-sealed deep groove ball bearings combined with various shapes of bearing housings. The bearing unit can be directly mounted onto the main body of machinery or equipment with several bolts. It features self-aligning capability, allows for grease replenishment, and is a product that is very easy to install and use. At the same time, the base adopts a stamped steel plate structure, offering excellent cost performance.

Product Feature:
1. Self-aligning function
2. Grease can be replenished (through the oil injection hole on the outer ring of the bearing)
3. Simple structure and easy installation

Precision:	JIS B 1558
	JIS B 1514
	JIS B 1559
	(GB/T 7809-1995)

Operating temperature: -15 to +100°C
At the time of delivery, the bearing and steel plate are not assembled as one unit; please assemble them together during installation.
The installation angle between the two set screws is 120°.

Installation Steps
1. Slide the bearing onto the shaft and move it to the specified position.
2. Align the mounting base (two steel plates) with the bearing and secure it to the machine with bolts. (After installation, the bearing is also fixed.)
3. After positioning the shaft, tighten the set screws to fix the shaft in place.

Bearing Life
When bearing units are installed and operated in machinery or equipment, even under suitable conditions, after a certain period of time, issues such as increased vibration, noise, or overheating of the bearing unit may sometimes occur. The period during which the bearing unit can no longer be used due to such reasons is called the service life of the bearing unit.
The service life of the bearing unit includes two types: one is the fatigue life, when the bearing can no longer be used due to material fatigue, and the other is the grease life, when it can no longer be used due to deterioration of the grease and poor lubrication. These can be determined separately as the bearing's rated life and the grease life.
The service life of the bearing unit is determined by whichever is shorter: the bearing's rated life or the grease life. By properly supplying lubricant, the grease life can be extended to match the bearing's rated life. When a mounted bearing is used without additional lubrication, its service life is the shorter of the bearing's rated life or the grease life.
However, when the bearing unit is installed and operated in machinery or equipment, failures may sometimes occur due to reasons other than the bearing's rated life or grease life (such as wear, indentation, fracture, or burning). These issues can be avoided by carefully considering the selection, use, installation, and lubrication of the bearing unit.

Calculation of Service Life
The relationship between the basic dynamic load rating, equivalent dynamic load, and basic rated life of the bearing—when the bearing unit is used at a certain rotational speed, it is more convenient to express the service life in terms of time, which is commonly used.
