Axis Skateboard 2317E/EK Self Aligning Ball Bearing Double Row

skateboard bearings 2317E/EK self-aligning ball bearing

In a self-aligning bearing, the inner ring has two raceways and the outer ring has a single spherical raceway with its center of curvature coincident with the bearing axis. Self-Aligning Double Row Ball Bearings are designed to work in applications where severe misalignment exists whether from mounting or shaft deflection. The concave raceway of the outer ring in combination with two rows of balls operate over a wide range of contact angles.

The self-aligning ball bearing has two structures: cylindrical hole and tapered hole. The material of cage is steel plate and synthetic resin. Its characteristic is that the outer raceway is spherical and has automatic alignment, which can compensate for the errors caused by different concentricity and axis deflection, but the relative inclination of the inner and outer raceways should not exceed 3 degrees.

There are cylindrical and conical inner holes in self-aligning ball bearings.
The taper of the conical inner hole is 1:1 2 or 1:30.
In order to enhance the lubrication performance of the bearing, the annular oil groove and three oil holes are machined on the bearing outer ring.
It mainly bears radial load and can bear small axial load.
The axial displacement of the shaft (housing) is limited within the clearance limit, with automatic centering performance, allowing the normal work under the condition of relatively small inclination of the inner and outer parts, suitable for parts where the coaxiality of the supporting seat hole cannot be strictly guaranteed.
