Applications

Engineering machinery: chassis travel agencies bearing wheels, towing wheel sleeve, tension wheel hub;
         Automotive industry: balance shaft bushings, steel pin bushings, steering shaft main Shaw sleeve, connecting rod sleeve, valve rocker sleeve, camshaft sleeve, differential bushings, gearbox bushings, internal combustion engine main bearing , Thrust washer;
         As well as the side of the piston pump, gear pump side pieces.

Advantages and Uses

The traditional relative movement of the hole and the shaft is a certain gap, and hole and the axis of movement between the friction coefficient, the use of ball retaining ring, the shaft and the hole is not in direct contact, but by the middle of the trace of interference Ball, and thus high precision, rolling friction instead of dynamic friction, rolling flexibility, the friction coefficient is small, long service life, both in the rotation, there are occasions to move, with oil-free or filling the shaft and axis, But the movement accuracy is low, with rolling bearings, can only meet the relative rotation of the shaft, and the ball to keep the ring, the above two conditions are met, has been widely used in cold die rolling mold, high precision machine tools, Machine tool accessories and require high-precision axial or axial radial movement at the same time.

Requirements for mating parts

1. Bushings: Material GCrl5, YB9, heat treatment, hardness HRC62 ~ 66, technical conditions by the GB / T12446 with the axis should have a radial interference between 0.01-0.02, the surface roughness of 0.05
2. Shaft: material GCrl5, YB9, heat treatment, hardness HRC62 ~ 66, technical conditions by GB / T12446, shaft tolerance using h5, the surface roughness of 0.05
3. Measurement: With the general measurement methods (pneumatic measuring instrument, the outer diameter of the micrometer, diameter dial gauge, etc.) measuring the size of the shaft guide sleeve and ball bias value, you can find the interference with the amount, that is Ymax = dmax + 2d'-DmIn, the required interference is 0.01-0.02mm
