ZKLDF Rotary Table Bearing

ZKLDF Rotary Table Bearing

ZKLDF are low-friction, high accuracy for very high speeds, high axial and radial loads and high demands on tilting rigidity. These bearings are particularly suitable for precision applications involving combined loads. Their preferred areas of use are bearing arrangements in rotary tables and honing heads as well as measurement and testing equipment.

Bearing features:
1.     High precision: precision at P4, P2.
2.     High rigidity: ZKLDF series bearings are with preload.
3.     High speed: can be applied in high speed working condition.
4.     Multi-direction load capacity: contact angular is 60°, and can support axial load, radial load, and tilting load.
5.     Low friction: small frictional torque.

Application:
can be widely applied in precision rotary table of the machining center, high precision measuring instrument, and medical equipment etc.

Remark:
1)Including retaining screws and threaded extraction holes.
2)referring installing screws.
3)Bearing frictional torque must test by speed 5r/min , the sartup frictonal torque should be 2-2.5 times of listed data .
