YRT Series
Rotary Table Bearings YRT Series
Features
Axial/Radial Bearings YRT series are large, double direction axial barings with a radial guidance bearings.
Holes are provide in the outer ring. Geometrical tolerances are within tolerance class ISO 4 combination of two axial needle roller bearings and one radial cylindrical roller bearing.
The axial component consists of two axial needle roller and cage assemblies.
The radial component of the bearing is full complement and lightly preload.
They can be relubricated through the outer ring and the L-section ring. The number of lubrication holes is determined by the bearings size.
Arrangement Tolerance
Center ring usually be tightened to the machine. In order to locate the center correctly, the inner and outer supporting housing should miss the tolerance range of h6 and J7. All the screws need to be cross tighened by torque spanner.
