Four Row Cylindrical Roller Design
• Large number of rollers and large contact area for higher load capacity.
• Inner and outer rings are usually separable, which makes mounting, dismounting and inspection easier.
High Radial Load Capacity & Rigidity
• Mainly designed to carry very heavy radial loads, suitable for heavy and extra-heavy duty conditions.
• High rigidity helps to improve the overall stability of mill stands and drive systems.
Suitable for Harsh Operating Conditions
• Designed for medium to high speed, heavy load and continuous running.
• Can be used with oil or grease lubrication systems to reduce friction, control temperature rise and extend bearing service life.
Easy Installation and Maintenance
• Separable design allows individual components to be installed separately, reducing installation difficulty and downtime.
• Convenient for inspection, replacement and maintenance of rollers and rings.

⚙️Typical Applications:
• Hot and cold rolling mills
• Continuous casting machines
• Heavy industrial gearboxes and drive units
• Other heavy machinery requiring very high radial load capacity and rigidity
| 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. |
