S1305 ceramic self-aligning ball bearing
Ceramic bearing, as an important mechanical base, has excellent performance that metal bearing can’t match, so it takes the lead in the world of new materials such as high temperature resistance and super strength. In the past ten years, it has been widely used in various fields of national economy and people’s livelihood.
Zirconia ceramic bearing: the whole ceramic bearing has the characteristics of anti-magnetoelectric insulation, abrasion resistance and corrosion resistance, oil free self-lubrication, high temperature and cold resistance, etc., which can be used in extreme harsh environment and special working conditions. The ring and rolling body are made of zirconia (ZrO2) ceramic material, the reholder is made of PTFE (PTFE) as the standard configuration, and the glass fiber reinforced nylon 66 (rpa66-25), special engineering plastics (PEEK, PI), stainless steel (AISISUS316), brass (Cu), etc.
Self-aligning ball bearing is a bearing equipped with a spherical rolling body between the inner ring of two raceway and the outer ring with spherical raceway. It can bear a large radial load and a certain axial load, as shown in figure 1. This kind of bearing outer ring raceway is spherical. Therefore, it has centering performance.
The main features of self-aligning ball bearing are:
(1) the outer ring raceway of self-aligning ball bearing is a part of a sphere, and the center of curvature is on the bearing axis. Therefore, the bearing has the function of self-aligning, which can be automatically adjusted in case of deflection of the shaft and shell. No additional bearing load. (2) it can bear radial load and an appropriate amount of axial load in both directions. But it can’t withstand torque loads. This kind of bearing has small contact Angle, which is almost constant under axial load, small axial bearing capacity and large radial load capacity, suitable for heavy load and impact load. (3) double-row adjustable ball bearings with locking sleeve and locking nut can be installed at any position on the optical shaft without needing to position shaft shoulder.
