Select the bearing type according to the direction of load
① bearing axial load only: angular contact bearing (one-way thrust ball bearing) is selected
② Bearing only radial load: single row radial ball bearing (deep groove ball bearing) or tapered roller bearing shall be selected
③ Bearing radial and axial alternating load: tapered roller bearing, angular contact bearing and deep groove ball bearing are selected
Axial fixation of rolling bearing (inner circle fixation method) one end of bearing inner ring is usually positioned by shaft shoulder or sleeve
① The shaft is fixed with a circlip: it is mainly used for occasions with low speed and small axial load
② Shaft end face retaining ring fixation: it can be used for high speed and large axial load, and is only applicable to the shaft end
③ Round nut and brake washer fixing: mainly used for occasions with high speed and bearing large axial load
④ The fixed bushing and round nut structure are used for fastening the self-aligning bearing with small axial force and speed on the long shaft.
Post code
Internal structure code:
This code is bearing immediately after the basic generation and is represented by letters to reflect the different internal structures of similar bearings, such as angular contact bearings C, AC and B, which represent the nominal contact angle respectively α 15 °, 25 ° and 40 °.
