Precision bearing of instrument

Low friction torque precision micro bearing is used in aerospace, precision instruments and other high-tech fields, which requires long service life and high reliability of the bearing. Due to the particularity of the service position, the lubrication of bearings is generally solid lubrication or thin oil lubrication.Instrument bearings are mainly used for sensors, outdoor weather instruments, horizontal instruments, marking instruments and infrared instruments.

1) Generally use ABEC5 or above precision instrument bearing.

2) The friction torque of the bearing should be small; Called miniature frictionless bearing.

3) Because the load is very small, the fatigue and life of the instrument bearing need not be considered, but certain requirements are required for noise; The instrument and meter industry generally requires highly sensitive miniature bearings.

4) When selecting the bearing fit, it is not necessary to consider the influence of load on life, but mainly consider the influence of thermal expansion of the shaft and shaft assembly. Therefore, the fit with small interference should be selected.

5) The working clearance of the bearing is small or zero, but negative clearance should be avoided to cause increased friction and temperature rise.

The bearings of Royal micro bearing company are widely used in all kinds of instruments and instruments, and now we have cooperation with many precision instrument manufacturers at home and abroad.

Among them, 6700ZZ (10x15x4) and 685ZZ (5x11x5) are used in geodesy instrument.

693(3x8x3), 692ZZ (2x6x3) are used in horizontal sensors, line-casting instruments, sweeping instruments, vertical alignment instruments.

624ZZ (4x13x5) is used for wind sensors.

682(2x5x.5) is applied to the raster line displacement sensor.
