Whether the bearing device is correct; directly affects the accuracy, life and function of the bearing. Therefore, the device and the device part of the device should be fully discussed; according to the operating specifications. Senior professors believe that the operation specification items are usually as follows: /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
Clear the bearing and associated components. View the dimensions and accuracy of the associated components. After viewing the bearing assembly, check that the filling smoothing agent is expected to be in the device; then open the bearing package. Usually the grease is smooth; the bearing is not removed; the smooth grease is directly filled. The oil is smooth. Usually; there is usually no need to remove; however; instruments or high-speed bearings; etc.; to be cleaned with clean oil; remove the rust inhibitor coated on the bearing. Remove the bearing of the rust inhibitor; easy to rust; Feel free to place.
Furthermore; bearings that have been sealed with smooth grease; do not clear directly.
Bearing device method; due to bearing layout, cooperation, conditions; because usually the shaft is rotated; so the inner ring needs to cooperate with the cooperation. Cylindrical hole bearing; multi-purpose press press; or hot-packing method. Cone hole occasion; Directly fixed on the tapered shaft; or with a tight sleeve device.
When the device is to the bearing seat; use the gap cooperation; when the outer ring has the interference; usually press with the press; or use the cooling method of the cooling device. Use dry ice as the coolant; cold shrink device; in the air The moisture will condense on the outer surface of the bearing. Therefore, it is necessary to adopt the anti-rust method. The above is the precautions of the NSK bearing that the professor summarized for us in the installation process; it depends on the specific situation.
Recommend to friends comments close window Bearing related knowledge How to extend the life of the rolling bearing? The basic layout of the rolling bearing is correct. The equipment NSK bearing can improve its function and the life bearing temperature. View the method to analyze the classification and scale of the electric insulating bearing.
