zys 80x146x35mm Axial and Radial YRT Slewing Bearing YRT80 without
TeethProduct DescriptionZYS can offer YRT series, YRTS series,
ZKLDF series, YRTM series, YRTSM series rotary table bearings.
About the performance comparison of YRT, YRTS and ZKLDF series
bearings with the same size, the limit speed of ZKLDF, YRTS, YRT
series bearings decrease in turn while the overturning rigidity of
YRTS, YRT and ZKLDF series bearings decrease sequentially. YRTM or
YRTSM rotary table bearings add a set of angular displacement
monitoring system on the basis of YRT or YRTS series bearings, to
overcome the defect of open-loop control of diagonal displacement
control, and realize closed-loop control of rotary table or
indexing plate, greatly improving the positioning accuracy of
angular displacement.Product structureThrust / radial
cylindrical roller bearings YRT and YRTS series are composed of two
thrust roller bearings and one radial cylindrical roller bearing.
Due to the special design of the internal structure of YRTS series
bearing, higher limit speed can be achieved. Thrust angular contact
ball bearings ZKLDF series consist of an integral outer ring, two
inner rings and two sets of steel balls and cage assemblies. Its
contact angle is 60, and it is especially for the conditions with
high requirements on high speed, high axial and radial loads and
overturning moment.Product FeaturesZYS turntable bearings are
ready-to-install high-precision turntable bearings, suitable for
occasions with high precision requirements and combined load. They
can withstand radial loads, bidirectional axial loads and
overturning moments with negative clearance. ZYS turntable bearings
have the characteristics of high precision, high rigidity and high
load capacity. In order to facilitate transportation and
installation, screw holes are opened on the inner ring and the
outer ring, and the entire set of bearings is fastened with
positioning screws. The bearings are preloaded at the factory, and
there is no need to adjust the clearance for installation.
