⚙️Product Description:
The 400752305 (25×68.2x42mm) is a heavy-duty cylindrical roller eccentric bearing engineered with a precision 4mm eccentricity for industrial reduction drives. Manufactured from high-grade chrome bearing steel and equipped with a robust solid brass cage, it delivers exceptional structural integrity and vibration damping under intense shock loads. As a trusted B2B bearing supplier, we proudly distribute this high-torque component under our proprietary RMO brand for machinery OEM manufacturers and rebuilders. If your specifications call for alternative top-tier global brands, our extensive trading network seamlessly provides multi-brand procurement solutions.

⚙️Product Features:
- Heavy-Duty Cylindrical Rollers: Utilizes precision-ground cylindrical rollers to maximize line-contact load capacity, easily sustaining continuous radial forces in heavy equipment.
- Solid Brass Cage Advantage: The robust brass cage provides superior fatigue resistance, low thermal expansion, and excellent lubrication retention in harsh, high-vibration operating conditions.
- Calibrated 4mm Eccentricity: Features an engineered 4mm offset sleeve design, enabling smooth trochoidal and cycloidal motion conversion without requiring complex external shaft machining.
- B2B Supply Agility: Boost your operational margins with our factory-direct RMO brand inventory, or leverage our established network to source original OEM-grade international bearing brands.
⚙️Product Application:
Highlighting high radial stiffness and precision eccentric motion, the 400752305 is heavily relied upon in:
- Cycloidal reducers, planetary speed changers, and industrial gearboxes.
- Heavy-duty textile machines, printing presses, and paper processing equipment.
- Mining machinery, metallurgical crushers, and vibrating screens.
- Automated drive systems and custom industrial eccentric shaft mechanisms.
⚙️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. |
