718 Series Angular Contact Ball Bearings

The 718 series angular contact ball bearings are commonly used in high-speed and high-precision applications such as machine tool spindles, CNC equipment, precision motors, robotic joints, measuring instruments, and compact spindle arrangements where limited radial space and stable rotation are required.

The 718 series is a thin-section precision series, designed for compact designs and high-speed operation. Compared with 719, 70, and 72 series bearings, the 718 series generally has a smaller cross-section and is suitable when space is limited. The 70 and 72 series usually offer higher load capacity, while the 719 series is also commonly used for high-speed precision spindle applications.

TEDIN can supply 718 series angular contact ball bearings in precision grades such as P5, P4, and P2, depending on the application requirements. For high-speed spindle and precision machine tool applications, P4 and P2 grades are commonly selected for improved running accuracy and vibration performance.

Yes. We can provide universal matching and paired bearing arrangements such as DB, DF, DT, and other customized combinations. Preload options can be configured according to operating speed, rigidity requirements, temperature rise, and axial load conditions.

Common contact angle options include 15°, 25°, and 40°, depending on the bearing design and load direction. Smaller contact angles are often used for higher-speed operation, while larger contact angles provide greater axial load capacity.

Available cage materials include phenolic resin, machined brass, polyamide, and PEEK, depending on the operating speed, temperature, lubrication method, and application environment. For high-speed spindle applications, phenolic resin and PEEK cages are commonly considered.

Yes. Depending on the size and working conditions, TEDIN can provide open type bearings, sealed designs, grease lubrication, oil lubrication compatibility, and special grease options for high-speed, low-noise, or high-temperature applications.

To recommend the right 718 series bearing, please provide the bearing model or dimensions, shaft speed, radial and axial load, mounting arrangement, required precision class, preload requirement, lubrication method, operating temperature, and application type.

Lead time depends on size, precision grade, preload configuration, and stock status. Standard or commonly used models may be available for faster delivery, while customized precision bearings or matched sets usually require additional production and inspection time.
