Product DescriptionCore Positioning and Product AttributesThe ZKLF2068 bearing is a classic double-row thrust angular contact ball bearing, belonging to the category of precision screw support bearings. Designed specifically for high-speed, high-precision screw drive systems, it is a core support component that achieves high dynamic response and positioning accuracy. It features an inseparable unitary structure consisting of a thick-walled outer ring, a double-row ball assembly, a cage, and an inner ring. This precision assembly ensures stable performance and is widely used in industrial applications that require both easy installation and operating accuracy.Specification Model Specifications and Key Parameters1. Model Interpretation (Using ZKLF40115-2Z as an Example)Model Segments MeaningZKLF Series Designation (Double-row Thrust Angular Contact Ball Bearing, Bolt-on Type)40 Inner Diameter (40mm, Tolerance - 0.005mm)115 Outer Diameter (115mm, Tolerance - 0.01mm)2Z Dust Covers on Both Sides (Gap Seal)CHIK - ZKLF Series Bearing part numbers:double row axial angular contact ball bearings: ZKLF2068-2RSZKLF2068-2ZZKLF2068-2Z-XLZKLF40115-2RS-XLZKLF40115-2RSZKLF40115Key Structural and Performance Features 1.Core Structural Design Double-row Layout and Contact Angle: Utilizing a double-row ball O-shaped arrangement with a fixed contact angle of 60°, it offers both axial and radial load capacity, making it particularly suitable for screw drives with predominantly axial loads. Combined with an optimized raceway profile, it offers outstanding anti-overturning performance (with a tilting stiffness of 750 Nm/mrad). Mounting: A hallmark of the ZKLF series, this model features 12 M8 fixing holes in the outer ring, allowing direct screw mounting to adjacent structural components. This eliminates the need for additional locating holes or bearing end caps, significantly simplifying assembly and reducing structural processing costs. The inner ring is clamped using INA-recommended ZMA40/62 or AM40 precision locknuts, accurately applying an axial preload of 25,185 N to eliminate play.Sealing and Lubrication System: The common suffix "2Z" designates a double-face gap seal, suitable for high-speed operation. With grease lubrication, the maximum speed reaches 3,100 r/min. A "2RS" lip-type contact seal is also available for enhanced dust and water resistance. The bearings are pre-loaded with GA28 standard lithium soap grease, and a lubrication port is provided on the outer ring for relubrication according to operating conditions.2. Performance AdvantagesHigh Precision and High Rigidity: Geometric tolerances are controlled through precision grinding, resulting in an axial runout of only 2.5μm and an axial stiffness of 1200 N/μm. This effectively suppresses vibration and deformation in the screw drive, ensuring equipment processing accuracy.Load-Carrying and Life Performance: The rings utilize a special heat treatment process to significantly enhance wear resistance. The basic rated axial dynamic load reaches 72,000 N and the static load reaches 149,000 N, meeting the requirements of long-term stable operation under medium-to-high load conditions.Low Friction: The optimized cage structure and ball guidance method reduce friction loss, resulting in a friction torque of only 0.65 Nm, minimizing operating temperature rise and ensuring stability under high-speed conditions.Applicable Scenarios and Application Value1. Core Application AreasPrecision Machine Tools: Ball screw supports for CNC machine tools and machining centers, suitable for high-speed cutting and precision positioning.Automation Equipment: Screw drive systems for electronic component packaging equipment and semiconductor wafer handling mechanisms, meeting high dynamic response requirements.High-end Manufacturing Equipment: New energy battery electrode forming machines, precision laser processing equipment, etc., ensuring operational stability under heavy loads and high speeds.2. Application ValueImproved Installation Efficiency: The direct bolt-on design eliminates the need for bearing seat machining and end cap assembly, reducing assembly time by over 40%.Strong performance adaptability: The combination of a high speed of 3100 r/min and a load capacity of 72,000 N covers a wide range of operating conditions, from high-speed light loads to medium-speed heavy loads.Comprehensive cost optimization: The maintenance-free design reduces downtime, while high-precision features reduce scrap rates caused by machining errors. Simplicity in adjacent structural designs also reduces manufacturing costs. After Sales ServiceStandard Warranty: 12 months or 2,000 operating hours (whichever comes first).Extended Warranty: Optional coverage up to 24 months.Global Support: 24/7 technical assistance .Company ProfileShandong CHIK bearings CHIK bearings established in 2001, produces a wide range of ball and roller bearings for automotive parts,agriculture machinery parts, various industrial machinery parts, ferrous metallurgy, chemical machinery and machine manufacturing in its primary plants in China mainland.
