What is 1204 self-aligning ball bearing?

The 1204 bearing is a widely used self-aligning ball bearing, which belongs to the self-aligning bearing series. It is designed to solve the problem of axis deviation caused by improper installation or equipment deformation, thereby improving the operating stability and reliability of mechanical equipment. The following will introduce the structure, performance, application and market situation of the 1204 bearing in detail.

Structure and parameters

The basic dimensions of the 1204 bearing are:

Inner diameter (d): 20 mm

Outer diameter (D): 47 mm

Thickness (B): 14 mm

The main feature of this bearing is that the outer ring track is spherical, and its curvature center is consistent with the bearing center, which allows the inner ring, ball and retainer to rotate freely around the bearing center, with good self-aligning ability. This design can effectively compensate for deviations caused by installation errors or equipment deformation.

These parameters show that 1204 bearings can maintain stable performance under high load and high speed conditions.

Application areas

Due to its superior performance, 1204 bearings are widely used in many industries and equipment, including but not limited to:

Fans: used in wind turbines and ventilation equipment.

Boring tools: provide high-precision support in metal processing.

Vertical conveyors: ensure smooth operation in logistics and automation equipment.

Pressure regulating valves: ensure stable flow in fluid control systems.

Battery testing equipment: used for precise positioning in battery production and testing.

Safety instruments: Provide support in various safety monitoring equipment.

Industrial tape: Used for conveying and positioning in production lines.

In addition, 1204 bearings are also suitable for equipment such as automotive lights, showing their wide applicability.

Summary

In short, as an important mechanical component, 1204 bearings play an indispensable role in modern industry with their superior self-aligning ability and wide range of applications. Whether in wind energy, manufacturing or other fields, 1204 bearings provide solid guarantees for improving equipment performance and extending service life. With the development of technology, the design and materials of this bearing are also constantly improving to adapt to more stringent working environments and higher performance requirements.
