(Angular Contact Ball Bearings) Can bear radial load and axial load at the same time. Can work under higher rotational speed. It is the bigger to be exposed to the angle, the higher axial bearing capacity is. High precision and high-speed bearing usually fetch 15 degrees and contact the angle. Under the function of axial force, contacting the angle will increase.

The angle of uniline is exposed to the axial load that the ball bearing can only bear a direction, while bearing radial load, will cause additional axial force. And can only limit the axle or outer cover in the axial displacement of a direction. The contact angle that the angle 連絡先 the ball bearing is 40 degrees, so can bear the axial load greatly. It contact by ball bearing not to be horn not design of separating,inside and outside differ shoulder level of both sides enclosed. For improving load ability of bearing,will pair shoulder of one side among them the processing is getting lower relatively, thus let the bearing put into more steel balls.

It is the master’s radial and axial union load and moment load that pair lists the angle and is exposed to the ball bearing and bear greater radial load, limit the axial displacement of two respects of the axle. Used mainly for restraining one pair of one that listed the angle and contacted in the ball bearing, between the outer laneses in the parts of the axle and two-way axial displacement of outer cover from being tiltable and limited, allow the angle of inclination to depend on internal interval, bearing size, inside design of the bearing and act on strength and moment on the bearing, allow the angle of inclination to guarantee to produce the too high additional stress in the bearing the most largely. If store in the bearing, between the outer lanes in the angle of inclination, will influence the life-span of the bearing, cause the bearing to operate the precision to drop at the same time, the noise of operating increases. Pair lists the angle and 連絡先 the ball bearing and generally adopts nylon to keep the shelf or brass entity keeping the shelf. Pair lists the angle should notice, though the bearing can bear the two-way axial load while contacting the installation of ball bearing, but when one side holds ball gaps, should notice that don’t let the main axial load be passed by the ditch of one side with gap. When the bearing uses should pay attention to, make without put the intersection of ball and side of gap roll one bear main load.

The ball bearing is as follows, that the angle 連絡先 7000C type (『=15 degrees) 7000AC type (『=25 degrees) With 7000B (『=40 degrees) Several kinds of types. The the intersection of lock and mouth of bearing, on outer lane, enclose, can’t separate generally, can bear radial and axial the intersection of union and load and one axial load of direction. It determines by the fact that exposed to the angle, it is the bigger to contact the angle, it is high to bear axially loaded ability to bear axially loaded ability. This kind of bearing can limit the axle or outer cover in the axial displacement of a direction.

It is relatively high to exposed to the ball bearing terminal rotational speed, can bear radial load and axial load at the same time, can bear purely axial load, it loaded ability is determined by the fact that exposed to the angle axially, and contact the increase of the angle to increase at the same time.

The angle of uniline 連絡先 the ball bearing: Main shaft of the lathe, high-frequency motor, fire the steam turbine, centrifugal separator, small-scale car front wheel, pinion axle of the differential mechanism, pressurized pump, oil drilling platform, food machinery, graduation head, mending the welder, low noise type cooling tower, electromechanical equipment, scribbling and installing the apparatus, lathe trough board, arc welder

Pair lists the angle and 連絡先 the ball bearing: Oil pump, thatch air-blower of the silk gauze, air compressor, all kinds of gear boxes, the fuel sprays the pump, printing machinery, planet moderating machine, extract the apparatus, put line moderating machine, food package packing machine, arc welding generator, electric iron, square case, gravity type spray gun, shelling the line machine, semi-axis, test analytical equipment, meticulous chemical machinery.



The name of product: Import the angle of NSK 7021A5 and contact the new type of the ball bearing: 7021A5 old type: 46121 internal diameters: 105( mm) External diameter: 160( mm) Thickness: 26( mm) Bearing material: High-carbon chromium bearing steel (quench completely type completely) (GCr15) Use: Common Type: The angle 連絡先 the ball bearing
