☆ product features -Aligning ball bearing has 2 goals, a common outer ring of concave spherical roller, and the curvature and the center bearing the same center, even if the inner ring, and steel cage as opposed to some of the outer ring tilt, can also rotate, so bearings Is a self-aligning, and not relative to the shaft bearings do not affect the box. The main radial load to bear, but also to bear a small amount of axial load, generally can not afford pure axial loading. Particularly for those who may have considerable axial deflection or misalignment of bearings applications. For example, precision instruments, and low electrical noise, cars, motorcycles, woodworking machinery, textile machinery of the shaft, mining machinery, electrical and mechanical equipment, plastic machinery, office equipment, medical equipment, fitness and sports equipment and general machinery, machine-building industry is in One of the most widely used type of bearings. ★ product categories ZWZ production-aligning ball bearing can be divided into two types: Cylindrical hole-aligning ball bearing Cone hole-aligning ball bearing Cylindrical hole-aligning ball bearing with their 2 and the ball in the outer ring of Globoidal Raceway, the self-aligning ball bearing can be automatically transferred, and to be able to bear the shaft and bearing between the point of error for likely Deflection axis and the axis of the heart caused by errors in working condition. -Aligning ball bearing friction is the lowest among all the rolling bearing, so even during the high-speed, still only has a small temperature rise. Cone hole-aligning ball bearing with a cylindrical hole-aligning ball bearing characteristics, but inside the cone hole to hole (conventional taper 1:12), installed in the cone axis can fine-tune the bearing clearance. Such bearings are used in the loading support Bending larger two-axis, as well as for the two hole can not guarantee that the parts of one mind in strict. The main radial load to bear, but also to bear a small amount of axial load, generally can not afford pure axial loading. Bearing such versatility after the deep groove ball bearings, the speed limit than the same specifications deep groove ball bearings to be low, but its carrying capacity than the high-deep groove ball bearings. Mid-size range ZWZ-aligning ball bearing basic dimensions are listed in size datasheets, Diameter size range: 25mm ~ 1100mm Outside diameter size range: 52mm ~ 1300mm Size range width: 15mm ~ 300 mm   ● Tolerance ZWZ standard-aligning ball bearing has a general level, with all GB307.1. ◇ radial clearance ZWZ standard-aligning ball bearing with C2, the standard (CN), C3, C4 and C5-level internal space, and all with GB4604. Cone hole-aligning ball bearing at C3 space as a standard. Radial clearance see the ＆#118alue in the form foreword, their ＆#118alue does not apply to the installation and non-load bearing. Internal space is greater than or less than the ＆#118alue of the standard bearings can be manufactured in accordance with user requirements. ◆ Cage Cage generally stamping frame, nylon and brass frame entity frame, a steel material, such as brass and synthetic resin. When the bearings D ≤ 200mm diameter, using steel plate (with) punching Cage, Cage's code did not post signs. When the bearing diameter D> 200mm, the use of brass entity Cage, Cage's post-code not sign. Nylon bearing the aircraft operating temperature up to +120 ℃, the need for high-temperature or in the worst conditions for the operation of bearings, could be considered entities brass frame. For non-standard bearing cage, prior contact with the ZWZ. □ equivalent dynamic load When Fa / Fr ≤ e, P = Fr + Y1Fa When Fa / Fr> e, P = 0.65Fr + Y2Fa In-e, Y1 and Y2 the ＆#118alue of available bearings table. ■ equivalent static load P0 = Fr + Y0Fa Y0-in ＆#118alue of available bearings table.
