Thin-walled bearings in encoder applications: Small bearings, big impact

发布日期:2025-09-18

As a specialist at Ningbo Shilong Bearing Co., Ltd. (brand: RCL), we are deeply aware of the importance of 6700 and 6800 series thin-walled deep groove ball bearings in precision encoders. As a key device that converts physical quantities (such as angle, position, and speed) into digital or electrical signals, the performance of encoders directly impacts the accuracy and reliability of the entire system.

Thin-walled bearings, particularly the 6700 and 6800 series, achieve extreme thinness, miniaturization, and lightweighting with their extremely thin cross-section. This perfectly aligns with encoders' requirements for compactness, high precision, and low friction.

Thin-walled bearings utilize a large number of small-diameter steel balls, effectively reducing frictional torque and achieving high rigidity and excellent rotational accuracy. This characteristic is crucial for accurate encoder measurement. Within the encoder, thin-walled bearings support core components such as the code disk, ensuring stable and precise rotation. In optical encoders, the code disk is engraved with a periodic pattern of light and dark stripes. As the code disk rotates, a sensor captures these changes and converts them into electrical signals.

Insufficient bearing rotational accuracy will directly lead to signal deviation, affecting the measurement accuracy of the entire system. In absolute encoders, each position corresponds to a unique digital code, placing extremely high demands on bearing precision and stability. Thin-walled bearings are an ideal choice for this purpose.

Thin-walled bearings demonstrate their value in a variety of encoder applications:

1. In servo motors, encoders serve as feedback elements, monitoring the motor shaft's rotation angle and speed in real time. The high precision of thin-walled bearings ensures precise control.

2. In embodied intelligent robotics, each joint requires precise control. Thin-walled bearings help encoders achieve this, ensuring coordinated robot motion.

3. In elevator control systems, encoders must provide reliable and accurate position and speed signals. The stability of thin-walled bearings ensures safe elevator operation.

Ningbo Shilong Bearing Co., Ltd. (brand: RCL) specializes in the production of 6700 and 6800 series thin-walled deep groove ball bearings. Our bearings utilize precision manufacturing processes to ensure high precision, high rigidity, and low friction, fully meeting the stringent performance requirements of encoders. RCL bearings also offer a variety of options, such as different dust cover styles (rubber seal - RS, iron seal - ZZ), to accommodate the diverse operating environments of encoders.

With the advancement of industrial automation, intelligent robotics, and precision medical equipment, the demand for encoder accuracy and reliability continues to rise. Thin-walled bearings, particularly the 6700 and 6800 series, in which RCL specializes, will continue to play an indispensable role in this precision encoder field with their lightweight, compact design, high rigidity, and low friction, providing solid support for precise measurement and control in modern industry.
