⚙️Product Description:
The SL04-5024NR (equivalent to 2NCF5024VR) is a double-row full complement cylindrical roller bearing specially designed for cable sheaves, crane pulleys, and heavy hoisting machinery. Featuring a 120 mm bore diameter, 180 mm outer diameter, and a width of 80 mm, this cageless bearing utilizes the maximum possible number of rollers to achieve extraordinarily high radial load capacity and structural rigidity. Equipped with contacting rubber seals (2RS) on both sides and an outer ring locating snap ring groove with snap ring (NR), it enables reliable axial positioning directly within the sheave hub. As a global trade specialist, we provide direct factory supply of our proprietary RMO brand alongside trusted global brand sourcing to ensure continuous operation in heavy lifting operations.
⚙️Product Features:
- Full Complement Roller Geometry: Eliminating the cage allows maximum roller packing density, delivering maximum radial load ratings and shock resistance in compact crane sheaves.
- Integral Snap Ring Location (NR): Features an engineered snap ring groove and locating ring on the outer ring, simplifying axial retention inside rope pulley hubs without additional spacers.
- Double-Sealed Contact Protection (2RS): Equipped with heavy-duty rubber contact seals on both sides to retain grease while preventing ingress of dust, moisture, and abrasive contaminants.
- Locating Bearing Axial Support: Designed with rigid ribbing to support axial loads in both directions, keeping the sheave perfectly aligned under fluctuating rope tension.
- Dual Sourcing Efficiency: Cost-optimized RMO factory direct stock combined with flexible sourcing for top tier international brands guarantees uninterrupted supply chain security.
⚙️Product Application:
- Crane Cable Sheaves and Rope Pulleys: Main hoisting and boom luffing sheaves in mobile cranes, harbor portal cranes, and tower cranes.
- Winch Drums and Hoisting Drives: Heavy winch assemblies, offshore tensioners, and marine deck machinery.
- Construction Elevators and Cableways: Vertical material hoist drive pulleys, passenger cableway sheaves, and mining skip guide wheels.
- Industrial Material Handling Systems: Automated overhead crane travel units, steel mill ladle crane sheaves, and heavy conveyor guide rollers.
⚙️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. |
