Requirements for Bearings in Linear Actuators (Push Rod Motor).
Linear actuators typically use two sets of bearings with the following requirements:
1.Excellent Dust Protection:
The bearings must effectively prevent external dust from entering the internal components, ensuring long-term performance and reliability.
2.Wide Operating Temperature Range:
The bearings should function reliably within a temperature range of -50°C to 150°C, ensuring they can handle both extremely cold and hot environments.
3.Low Noise Operation:
The bearings must operate quietly, minimizing noise levels during operation, which is crucial for maintaining a pleasant working environment.
4.Service Life:
Designed for longevity, these bearings should have a long service life with minimal maintenance requirements, enhancing overall system reliability and reducing downtime.
What's the Performance Features of 6903 ZZ Bearings in Linear Actuators(Push Rod Motor)?
