Product Description Product Description Detailed Photos Structure:Angular contact ball bearings consist of an inner ring, outer ring, rolling elements (steel balls), and a cage.The raceways of the inner and outer rings are designed at a specific angle (contact angle), enabling the bearing to withstand both axial and radial loads.The contact angle is typically 15°, 25°, 30°, or 40°. A larger contact angle provides greater axial load capacity.Features:High-speed capability: The compact design and low friction make angular contact ball bearings suitable for high-speed operation.High precision: Commonly used in precision machinery, such as machine tool spindles and robotics.Combined load capacity: Can withstand both radial and axial loads simultaneously.Paired use: Can be mounted in pairs (back-to-back, face-to-face, or tandem) to handle bidirectional axial loads or higher radial loads.TypesBased on design and application requirements, angular contact ball bearings can be categorized into the following types:Single-row angular contact ball bearings:Can only withstand unidirectional axial loads.Typically require paired installation to handle bidirectional loads.Double-row angular contact ball bearings:Equivalent to a combination of two single-row bearings, capable of withstanding bidirectional axial loads.More compact design, suitable for applications with limited radial space.Four-point contact ball bearings:Can withstand bidirectional axial loads.Ideal for applications with high axial loads and requiring high rigidity.High-speed angular contact ball bearings:Use ceramic balls or special cage designs, suitable for ultra-high-speed applications. plicationsAngular contact ball bearings are widely used in the following fields:Machine tools: Used in high-precision, high-speed components such as spindles and lead screws.Automotive: Used in wheel hubs, gearboxes, and differentials.Aerospace: Used in high-precision, high-reliability components such as engines and landing gear.Robotics: Used in joints and rotating components.Electric motors: Used in high-speed motors and generators.Selection and InstallationSelection Considerations:Choose the contact angle based on load direction: A larger contact angle is suitable for higher axial loads, while a smaller contact angle is better for higher radial loads.Select the bearing type based on speed: High-speed applications require high-speed angular contact ball bearings or ceramic ball bearings.Choose single-row or double-row bearings based on installation space.Installation Notes:Angular contact ball bearings are often installed in pairs to ensure bidirectional load capacity.Pay attention to the bearing orientation during installation to ensure the load acts on the correct contact angle.Use dedicated tools for installation to avoid direct hammering on the bearing. Advantages and LimitationsAdvantages:High-speed capability.High precision and rigidity.Combined load capacity.Compact design, saving space.Limitations:Single-row bearings can only withstand unidirectional axial loads.Installation and adjustment are relatively complex, requiring expertise and specializedMaintenance and CareRegularly inspect the lubrication condition to ensure sufficient and clean lubricant.Avoid overloading or impact loads to prevent bearing damage.For high-speed or high-temperature applications, choose high-temperature lubricants or special material bearings.Product ParametersDesignationPrincipal dimensionsBasic load ratingsSpeed ratings dynamicstaticReference speedLimiting speed d[mm]D[mm]B[mm]C[kN]C0[kN][r/min][r/min] 7200 BECBP 10 30 9 7.02 3.35 30 000 30 000 7200 BEP 10 30 9 7.02 3.35 30 000 30 000 7201 BECBP 12 32 10 7.61 3.8 28 000 26 000 7201 BEGAP 12 32 10 7.61 3.8 28 000 26 000 7201 BEP 12 32 10 7.61 3.8 28 000 26 000 7301 BE-2RZP 12 37 12 10.6 5 26 000 20 000 7301 BEP 12 37 12 10.6 5 26 000 24 000 7202 BE-2RZP 15 35 11 8.32 4.4 24 000 20 000 7202 BECBP 15 35 11 8.8 4.65 24 000 26 000 7202 BEGAP 15 35 11 8.8 4.65 24 000 26 000 7202 BEGBP 15 35 11 8.8 4.65 24 000 26 000 7202 BEP 15 35 11 8.32 4.4 24 000 24 000 7302 BE-2RZP 15 42 13 13 6.7 22 000 17 000 7302 BECBP 15 42 13 13 6.7 22 000 20 000 7302 BEP 15 42 13 13 6.7 22 000 20 000 7203 BE-2RZP 17 40 12 10.4 5.5 22 000 17 000 7203 BECBM 17 40 12 11 5.85 22 000 30 000 7203 BECBP 17 40 12 11 5.85 22 000 22 000 7203 BEGAP 17 40 12 11 5.85 22 000 22 000 7203 BEP 17 40 12 10.4 5.5 22 000 20 000 7203 BEY 17 40 12 10.4 5.5 20 000 20 000 7303 BE-2RZP 17 47 14 15.9 8.3 20 000 15 000 7303 BECBP 17 47 14 15.9 8.3 20 000 19 000 7303 BEGAP 17 47 14 15.9 8.3 20 000 19 000 7303 BEP 17 47 14 15.9 8.3 20 000 19 000 7204 ACCBM 20 47 14 16 9.3 20 000 30 000 7204 BE-2RZP 20 47 14 13.3 7.65 19 000 14 000 7204 BECBJ 20 47 14 14.3 8.15 19 000 19 000 7204 BECBM 20 47 14 14.3 8.15 19 000 26 000 7204 BECBP 20 47 14 14.3 8.15 19 000 19 000 Certifications Packaging & Shipping Company ProfileInstallation InstructionsInstallation Guide for Angular Contact Ball Bearings1. Preparation Before InstallationBefore installing angular contact ball bearings, follow these steps to ensure optimal performance:Check the bearing: Inspect for any visible damage, contamination, or corrosion before installation.Clean components: Ensure that the bearing housing and shaft are clean, dry, and free of dust or metal particles.Lubrication: Use the appropriate grease or oil for lubrication, considering the application requirements.2. Installation MethodsA. Single Angular Contact Ball Bearings InstallationThese bearings must be installed in a specific direction, as they can only support axial loads in one direction.Ensure that the marked side or thicker ring is facing the axial load direction.Use a press or induction heater to mount the bearing onto the shaft to avoid damage.B. Paired or Matched Bearings InstallationAngular contact ball bearings are often used in pairs or sets to handle axial loads in both directions. Common arrangements include:Back-to-Back (DB, "O" arrangement) - For high rigidity and resistance to moment loads.Face-to-Face (DF, "X" arrangement) - Suitable for applications where shaft alignment may vary.Tandem (DT arrangement) - Used to accommodate high axial loads in one direction.When installing matched bearings, ensure they are positioned correctly as per the arrangement type.C. Press-Fit InstallationAlways apply force only to the inner ring when mounting on the shaft and to the outer ring when pressing into the housing.Avoid direct hammering; use a fitting tool or press to prevent bearing damage.If using an induction heater, do not exceed 120°C (248°F) to avoid material expansion and deformation.3. Post-Installation ChecksRotate the shaft manually to ensure smooth movement and no abnormal noise.Verify preload settings if applicable, especially for high-speed applications.Check axial play and alignment to prevent premature wear.4.
