Product Description

Single row angular contact ball bearings can only bear the axial load in one direction, and will cause additional axial force when bearing radial load. And can only limit the axial displacement of the shaft or housing in one direction. Angular contact ball bearings have a contact angle of 40 degrees, so they can withstand large axial loads. Angular contact ball bearings are of non-separable design, with shoulders at different heights on both sides of the inner and outer rings. To increase the bearing's load capacity, one of the shoulders is machined lower, allowing the bearing to fit more balls.

Double row angular contact ball bearings can withstand larger radial loads and combined radial and axial loads and moment loads, limiting the axial displacement of the shaft on both sides. The inclination between the inner and outer rings of the double row angular contact ball bearing is limited in the components that are mainly used to limit the bidirectional axial displacement of the shaft and the housing. The allowable inclination angle depends on the internal clearance of the bearing, bearing size, internal design and the effect on The forces and moments on the bearing, and the maximum allowable inclination angle should ensure that excessive additional stress is not generated in the bearing. If there is an inclination angle between the inner and outer rings of the bearing, the service life of the bearing will be affected, and at the same time, the running accuracy of the bearing will decrease and the running noise will increase. Double row angular contact ball bearings generally use nylon cages or brass solid cages. When installing the double row angular contact ball bearing, it should be noted that although the bearing can bear bidirectional axial load, if there is a gap for the ball on one side, care should be taken not to let the main axial load pass through the groove on the side with the gap. When the bearing is used, care should be taken to make the side raceway without the ball-loading notch bear the main load.

NSK ball screw bearings can withstand both radial and axial loads. Can work at higher speeds. The larger the contact angle, the higher the axial load carrying capacity. The contact angle is the angle between the line connecting the contact points of the ball and the raceway in the radial plane and the line perpendicular to the bearing axis. High-precision and high-speed bearings usually take a 60-degree contact angle. Under the action of axial force, the contact angle will increase. NSK ball screw bearing accuracy grades include dimensional tolerances and rotational accuracy. The precision is expressed as P5, P4, P2 from low to high.

Main uses of NSK ball screw bearings: machine tool spindles, high-frequency motors, gas turbines, centrifugal separators, front wheels of small cars, differential pinion shafts, booster pumps, drilling platforms, food machinery, indexing heads, repair welding Machines, low-noise cooling towers, electromechanical equipment, painting equipment, machine tool grooves, arc welding machines, oil pumps, roots blowers, air compressors, various transmissions, fuel injection pumps, printing machinery, planetary reducers, extraction equipment , Cycloidal reducer, food packaging machinery, electric welding machine, electric soldering iron, square box, gravity spray gun, wire stripping machine, half shaft, inspection and analysis equipment, fine chemical machinery.
