The JLM 603048F/603013Z RICH is a high-precision single row tapered roller bearing belonging to the metric "J-series" (JLM). Engineered to handle combined radial and axial loads with extreme efficiency, this bearing features dimensions of 45 mm bore, 78 mm outer diameter, and 21.5 mm total width. It is an ideal solution for applications where high load capacity must be maintained within a standardized metric footprint.

The internal geometry is designed to distribute loads evenly across the tapered rollers, which significantly reduces friction, heat generation, and rotational torque. The separable construction — consisting of the cone (inner ring assembly) and the cup (outer ring) — allows for independent installation. This feature facilitates the precise setting of internal clearance or preload, which is critical for the stability and service life of high-performance transmission and axle systems.

Manufactured to meet rigorous industrial standards, the JLM 603048F/603013Z RICH offers exceptional structural stiffness. It is built to ensure reliable performance in heavy-duty automotive and industrial drivelines, providing high resistance to wear and fatigue.

Key Performance Advantages:

• Optimized Combined Load Support: Specifically designed to manage simultaneous radial and thrust loads in one direction.
• Separable Component Design: Simplifies the mounting and inspection processes in complex mechanical housings.
• Precision J-Series Engineering: Manufactured to exacting metric tolerances for a perfect aftermarket fit.
• High Durability: Built with premium-grade materials to withstand the stresses of high-torque environments.
• RICH Quality Control: Ensures consistent performance, reduced vibration, and an extended operational life.

Typical Applications:

• Automotive transmissions and specialized differential assemblies.
• Agricultural machinery gear units and axle supports.
• Industrial gearboxes and motorized speed reducers.
• Vehicle wheel hubs for commercial and light-duty transport.
