Spherical roller bearings installed thrust Note what?

Spherical roller bearings are mainly used to bear radial load, but also can bear any direction of the axial load, high radial load capacity, especially for heavy duty or vibration load, but can not withstand the pure axial Load, aligning good performance, to compensate for coaxial error. Mainly used for rolling machinery. The following bearing technical personnel thrust spherical roller bearings to explain to you about the installation of the notes which?
Thrust-aligning roller bearings Features:
1. The bearing load line and the bearing axis of the formation of a certain angle, axial load capacity, in the axial load while under a certain radial load.
2. This kind of bearing spherical roller inclined arrangement, the seat raceway surface is spherical, has the self-aligning performance, therefore may allow the axis to have the certain inclination. Can be used in heavy load occasions, allows a higher speed, the use of oil lubrication in general.
3. Load is relatively large, for low speed, can be self-aligning (bearing inner sleeve and jacket tilt can still work) Bearing has two kinds of copper and steel cage, with inner ring with a taper.
Installation Precautions:
1. If the opening and closing times are short, apply a clean wrapper to cover the bearing. If the interval between unpacking and assembly is long, re-wrap the bearing in a clean wrapper. Dust-proofing agents on bearings are usually compatible with most lubricants, so new bearings need not be cleaned prior to assembly. If the bearing surface is contaminated with more dust-proofing agents, use a clean cloth to remove it from the outside diameter of the bearing, As well as erase the edges.
2. If it is used for machine tool spindle and other high-speed, precision parts of the use of special lubricant bearings, the probation period may need cleaning.
3. If the bearings with different production lot numbers are used in common, or if the bearings are installed in the opposite direction, the clearance or preload may not be correct. If the clearance is too small, the temperature will rise at work, resulting in bearing burns; the other hand, if the clearance is too large, may cause vibration caused by running accuracy.
