NTN Thrust Ball Bearing 51407 in StockDescription for thrust ball bearing
Thrust ball bearings can withstand high speed thrust load design, the washer-shaped ball rolling with a rolling groove ferrule constituted. Since the saddle-shaped rings, therefore, thrust ball bearings are divided into flat seat type and self-aligning spherical seat of two types. In addition, the bearings can withstand axial load, but can not bear radial load.
. type of thrust ball bearing
By the force of sub-way and two-way thrust ball bearings thrust ball bearings. Thrust ball bearings can withstand axial load.
Thrust ball bearings can withstand axial load. Thrust ball bearings, ring and the shaft with. Appear before the installation of seat spherical bearings with aligning properties, can reduce installation errors.
Thrust ball bearings can bear radial load, lower speed limit.Feature for thrust ball bearing
1. equipped with one-way, two-way two types
2, thrust ball bearings can withstand axial load, one-way thrust bearings can withstand a direction of axial load, two-way thrust bearing can withstand both directions alternating axial load.
3, thrust ball bearings can not restrict the radial shaft or housing movement, its low speed limits, one-way thrust bearings can limit the axis or axial movement of the housing side, two-way bearing can limit the shaft or housing in two axial moving direction.
4, when using this bearing, if the shaft and housing bore axis misalignment will cause premature bearing damage, in order to eliminate this undesirable phenomenon, may be left out of 0.5 between the live ring and the outer diameter of the housing bore ~ l mm radial clearance. It also requires the centerline of the shaft and the housing should be kept perpendicular to the bearing surface, in order to eliminate the center of the bearing housing by the support surface is not perpendicular to the centerline of the shaft caused by the tilt can be elastic pad lining live ring support surface, such as cloth, leather and oil rubber pad.
5, thrust ball bearings in operation, due to the inertial force, but also generated between the ball and raceway slide, leaving the temperature increased, the working surface easily damaged. Therefore, in order to prevent sliding between the ball raceways, thrust ball bearings in the work must be a minimum axial force.
6. In order to allow the installation error, whether it is one-way or two-way, you can choose spherical self-aligning spherical seat type or spherical seat type.Application for thrust ball bearings
Applies only to withstand side of the axial load, the speed on the lower parts, such as crane hooks, vertical pumps, vertical centrifuge, jack, speed reducer and so on. Shaft bearing ring, seat ring and rolling elements are separated, you can dismantle respectively.More part number for the thrust ball bearings we can offer
