A ZKLDF bearing is a specialized, high-performance turntable bearing designed for various precision applications. It features double rows of rollers arranged orthogonally at 90°, forming an "X"-shaped contact line, which enables even distribution of composite loads. The integrated track design of the inner and outer rings reduces assembly errors and enhances system rigidity. This bearing can efficiently bear radial force (≤50 kN), axial force (≤30 kN) and moment (≤3000 N·m) simultaneously, while maintaining low friction (friction coefficient ≤ 0.0015) and stable operation in different environments. It is a core component in many precision systems, directly affecting the performance and service life of the equipment. As a professional bearing manufacturer, NEWBEE Transmission's ZKLDF bearings, relying on advanced material selection and precision machining processes, have excellent performance, fully meeting the requirements of various precision applications.

Working Principle of ZKLDF Bearings
Radial Load: Transmitted through the vertical contact of the double rows of rollers, resulting in a uniform stress distribution.
Axial Load: The end faces of the upper row of rollers bear the thrust force, and the lower row of rollers balances it in the opposite direction.
Moment Load: The rollers on the diagonal resist the overturning moment, reducing deformation.
Lubrication System:
Grease Lubrication: Krytox® high-temperature lubricating grease is applicable in the temperature range from -30°C to 120°C, suitable for medium and low speeds (≤300 rpm).
Oil Lubrication: The built-in oil circuit supports circulating oil cooling and is suitable for high-speed scenarios (≤500 rpm).
With its excellent composite load capacity, ultra-high precision and environmental adaptability, ZKLDF bearings are widely used in various precision equipment and systems:
CNC Rotary Tables: Rotary worktables of five-axis machining centers and vertical lathes, where their high precision and load-bearing capacity ensure accurate rotation and processing.
Industrial Robots: Slewing supports of heavy-duty robotic arms, providing stable support and precise movement for the robot's operation.
Precision Instruments: Rotary platforms of optical inspection equipment, meeting the high-precision requirements of optical detection.
New Energy Equipment: Yaw mechanisms of wind turbines, adapting to the harsh working environment in new energy fields.
Optical Theodolites: Such as the Serbian Optical Theodolite application, demonstrating its reliability in precision optical instruments.
