Product Overview

Economical Adjustable Framed Spherical Bearing Unit, Cast Type
The adjustable framed bearing unit consists of a bearing housing, an outer frame, and an adjustable screw mechanism.
The bearing housing is used to install the bearing, providing support, self-alignment, and positioning.
The outer frame is available in stamped, cast, and welded types. It is used to secure and protect the bearing housing, and can be directly mounted to the main body of the machinery or equipment using bolts through the mounting holes on the outer frame.
The adjustable mechanism uses a screw adjustment, allowing users to adjust the position, angle, or tightness of the bearing housing within a certain range to meet specific installation requirements or achieve optimal bearing performance.

This series of outer frames adopts an integrated ductile iron (QT450) casting structure, offering excellent rigidity and strength. The mounting surface is finely milled for high installation accuracy.

Product Feature

Product Feature:
The adjustable framed bearing assembly features self-aligning bearings and adjustable positioning, making it suitable for a variety of applications such as mechanical transmission systems, conveying mechanisms, and rolling mechanisms. By adjusting the position or angle of the bearing housing, the load distribution of the bearing can be improved, vibration can be reduced, accuracy can be increased, and the normal operation of the system can be ensured.
It provides a flexible solution with significant advantages in applications such as alignment/calibration of shaft position accuracy, adjustment/compensation of operating loads, and modular quick installation/maintenance/replacement. This helps improve the performance and reliability of mechanical systems.

Usage Method

Installation Steps
1. Slide the bearing onto the shaft and move it to the specified position.
2. Secure the outer frame to the machine with bolts.
3. After positioning the shaft, tighten the set screws to fix the shaft in place.
4. Adjust the screw rod to bring the bearing housing to the optimal position or angle.

Precautions

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.
