YRT basic rotary table bearings are designed with a radial full roller, two groups of axial needle roller, cage assembly, an out ring, an L-section inner and the second ring. The out ring and inner ring have fixing holes, so the bolt can fix the bearings directly. YRT rotary table bearing structure can bear double-direction axial load, radial load and tilting moment. This series bearing have preload before leaving factory, no need to adjust clearance when installed. This series bearing is particularly suitable for the situation of high precision, high stiffness, low speed, and short rotate period such as rotary table, index heads and revolving milling heads.
This kind of bearing has axial and radial running precision for your chosen.

The measurement of angular displacement is very important in modern industry. Especially in machine tool industry, the rotation angle of mechanical parts was often highly demand. This needs to accurately measure and control the angular displacement.
At present, grating encoder, magnetic gate encoder was commonly used when measuring the angular displacement. But Austria AMOSIN steel grade measurement system we choose has four significant advantages of high precision (The highest resolution angle < 2arc-second）, stain resistance，no electrical induction，high adaptability to circumstance.
The YRT rotary table bearing with this measurement system, have very high precision, can bear double-direction axial load, radial load and tilting moment. That is very suitable for the high precision demand field, such as high precision rotary table in machine tools industry, dividing head and scientific experiment and measurement and so on.

ZKLDF axial angular contact ball bearing series have a unity outer ring, two inner ring, two rows of ball rollers and cage assembly, and contact angle is 60°. The outer rings and inner rings have fitting holes and easy to fit by joint bolt. The unit is located by means of retaining screws for the safety of transport and handling.
ZKLDF axial angular contact ball bearing series have double side sealing covers which can against dirt, impurities and avoid grease leak. ZKLDF axial angular contact ball bearing series using complex barium-base grease, you can add the grease through grease hole.
ZKLDF axial angular contact ball bearing series are designed with 60°contact angle and two rows of ball rollers, which can support radial load, double axial loads and tilting moments. Due to the special design with copper cages, the bearing has higher strength and lower friction torque. So this kind of bearings is especially applied to the situation with super speed, long time running, high stiffness and high precision. At the same time it can ensure high rotary precision. ZKLDF bearings can be applied to high speed rotary worktable, milling, grinding，honing head and precision measuring instruments.
