⚙️Product Description:
The 7011C-2RS (55x90x18mm) is a ISO P5 high-precision angular contact ball bearing featuring a 15-degree contact angle (C) and dual NBR contact rubber seals (2RS). Engineered with premium vacuum-degassed GCr15 bearing steel rings and precision steel balls guided by a high-rigidity phenolic resin or synthetic resin cage, this bearing accommodates heavy combined radial and unidirectional axial loads at high rotational speeds. We offer our cost-effective proprietary RMO brand 7011C-2RS precision bearings alongside flexible global brand sourcing solutions to suit your exact machine tool spindle and dynamic mechanical requirements.

⚙️Product Features:
- 15-Degree Contact Angle (C): Small contact angle design minimizes axial clearance while delivering superior high-speed performance and high axial rigidity.
- ISO Class 5 Precision (P5): Manufactured to strict P5 tolerances for exceptional dimensional consistency, minimal runout, and ultra-smooth operation under high RPM.
- Dual NBR Contact Seals (2RS): Premium synthetic rubber seals tightly block cutting fluid, coolant, micro-dust, and abrasive contaminants while retaining factory-loaded grease.
- Hardened Vacuum-Degassed GCr15 Steel: Precision-ground raceways ensure high fatigue strength, minimal thermal deformation, and extended fatigue life under heavy loads.
- Dual Brand Sourcing Options: Available in our factory-direct RMO brand for budget optimization, as well as original options from top-tier global precision bearing manufacturers.
⚙️Product Application:
- CNC Machine Tool Spindles: High-speed milling spindles, lathe workheads, and precision grinding machine shafts requiring high radial accuracy and rigidity.
- High-Speed Motor Units: Servo motors, high-frequency electric spindles, and precision encoder drive units operating under high thermal environments.
- Precision Medical and Testing Equipment: Medical imaging rotary stages, high-speed centrifuges, and automated laboratory analytical devices.
- Robotic Joint Drives: High-precision speed reducers, robotic arm base swivels, and automated linear positioning units.
⚙️Precautions:
| 1. Keep clean | 2. Use with caution | 3. appropriate tool | 4. Hot-loading | 5. Be careful of rust |
| Dust will have a bad effect on the bearing, so keep the surrounding clean. | Strong impact during use can easily cause scratches and indentations. | Avoid replacing existing tools, and use appropriate tools. | Bearings are precision parts, so hot installation is recommended. | Sweat on your hands during operation will cause rust, so it is best to wear gloves. |
