Hybrid Ceramic Angular Contact Ball Bearing 7200 CD/HCP4A High Capacity D Design Universally Matchable Bearing
The 7200 CD/HCP4A is a hybrid ceramic super precision angular contact ball bearing built for high capacity and high rigidity applications in robotics, servo motors and precision rotating equipment. Its D design internal geometry enlarges the ball complement to increase load carrying capacity, while the 25 degree contact angle provides excellent axial rigidity for moment and thrust loading. The universally matchable feature allows single bearings or any combination of pairs and sets to be mounted without special ordering, which simplifies assembly planning for manufacturers of robot joints, linear actuators and machine tool feed systems. Hybrid ceramic balls further reduce heat generation and extend grease life under continuous duty cycles.
Key Features- High Capacity D Design: Enlarged ball complement increases radial and axial load carrying capacity compared with standard designs.
- Hybrid Ceramic Balls: Silicon nitride balls reduce friction, lower temperature rise and improve high speed capability.
- 25 Degree Contact Angle: Provides high axial rigidity and moment stiffness for robot arms, rotary tables and feed units.
- Universally Matchable: Bearings can be mounted singly, in tandem, O arrangement or X arrangement without matched set ordering.
- P4A Precision Grade: Tolerance class better than P4 ensures consistent running accuracy and interchangeability in pairs.
- Low Friction and Temperature Rise: Optimized raceway geometry and cage design keep operating temperatures stable under load.
- OEM Interchangeability: Dimensional and performance compatibility with leading European and Japanese super precision bearing series.

This super precision angular contact ball bearing is ideal for robot joint reducers, servo motor shafts, ball screw support units, machine tool feed spindles, medical imaging equipment, textile machinery and semiconductor handling systems. The high capacity D design and universally matchable feature make it especially suitable for equipment builders who assemble bearing pairs or sets on site and need reliable axial rigidity without complex matched set logistics. Export oriented OEM manufacturers also use this bearing in packaging machines, printing presses and CNC rotary tables.
Packaging & Quality AssuranceEvery bearing is inspected for dimensional accuracy, running noise and vibration before shipment. Products are packed in anti-rust paper, individual plastic bags and export grade cartons with foam inserts to prevent transit damage. Our factory operates under IATF16949:2016 quality management standards and supports OEM and ODM customization including special clearances, preloads, sealing variants and matched pair arrangements.
