ZARN ZARF Combined Bearing
Combined thrust roller bearing (combined bearing) is assembled with radial needle roller bearing and thrust roller. This kind of bearing can carry both radial force and axial force. It is widely used in metallurgy equipment, textile equipment, printing machine, etc.
Main characteristic
►Withstand both radial force and axial force
►High precision
►No need to combine with other bearing, convenient to use, save space
