BLDF Rotary Table Bearings

BLDF rotary table bearing parameters

BLDF rotary table bearing has the characteristics of low friction, high motion accuracy under high rotation, and higher working speed than the general limit. It has high axial bearing capacity and high radial load, and its tilt stiffness is also high. relatively high. The field of complex load and precision management is in great need of this special technology, especially the equipment such as machine tool rotary table, grinding head and various functional testing processes are widely used. Since the BLDF rotary table bearing has two inner rings , the fit clearance should be determined according to the size of the inner ring with a small inner diameter.

Installation method of BLDF turntable bearing

1. Inspection before installation

First observe whether there are burrs on the surface, and then confirm whether the bolt holes, lubricating oil holes are cleaned, whether the bearing surface is dry, and ensure that the installation table is level, check whether the dimensions of the shaft and seat holes are consistent; whether the plane and parallelism of the end face are good Good; whether the perpendicularity of radial plane and axial plane is qualified.

2. Matters needing attention during installation

The temperature of 50-55 is the temperature of the inner ring of the heating shaft. At the same time, the bearing with the measurement system will be destroyed by induction heating, so do not use it. Also follow the steps a little bit to tighten the bolts.

3. Inspection after installation

First check whether there is any problem with the rotation of the bearing. It should be noted that the grade of the bolt should not be too high, and the locking torque should not be too large.
