2. Safety Information
Always prioritize safety when working with machinery and industrial components. Failure to follow safety precautions can result in injury or damage to equipment.
- Wear appropriate personal protective equipment (PPE), including safety glasses and gloves.
- Ensure machinery is de-energized and locked out before installation or maintenance.
- Handle bearings with care to prevent damage to precision surfaces.
- Consult relevant industry safety standards and local regulations.
- Keep the work area clean and free of debris.
3. Product Overview
The SKF R1502-EL is a high-quality cylindrical roller bearing designed for applications requiring high radial load capacity and high speeds. It features a full roller cage assembly, excluding the inner ring, and is manufactured from durable alloy steel.
3.1 Key Features
- High Radial Load Capacity: Designed to withstand significant radial forces.
- Durable Construction: Manufactured with high-quality alloy steel for strength and longevity.
- Full Roller Cage Assembly: Ensures precise roller guidance and even load distribution.
- Inner Ring Excluded: This design allows for easier installation and removal in certain applications.

4. Setup and Installation
Proper installation is crucial for the performance and lifespan of the bearing. Consult a qualified technician if you are unsure about any step.
4.1 Pre-Installation Checks
- Inspect the bearing for any signs of damage during transit.
- Ensure the shaft and housing seats are clean, free of burrs, and within specified tolerances.
- Verify that all necessary tools and equipment are available.
4.2 Installation Procedure
The SKF R1502-EL bearing is designed without an inner ring, which simplifies installation in certain configurations. The outer ring with the roller and cage assembly is typically pressed or heated onto the shaft or into the housing.
- Mounting the Outer Ring Assembly:
- For interference fits, use a hydraulic press or induction heater. Never strike the bearing directly with a hammer.
- Ensure even pressure is applied to the face of the outer ring.
- If heating, do not exceed 120°C (248°F) and ensure even heating.
- Inner Ring Installation (if applicable):
- If a separate inner ring is used, install it onto the shaft according to manufacturer specifications, ensuring proper alignment.
- Lubrication: Apply compatible lubricant (grease) as specified in the maintenance section before final assembly.
- Final Checks: After installation, manually rotate the shaft to ensure smooth operation and absence of abnormal noise or resistance.
5. Operating Principles
Cylindrical roller bearings are designed to accommodate high radial loads. The rollers have a modified line contact with the raceways, which reduces stress concentrations. The R1502-EL, with its full roller cage assembly, ensures precise guidance of the rollers, contributing to high speed capability and reduced friction.
The absence of an inner ring in this specific model allows for a larger shaft diameter within the same bearing envelope, or for the shaft itself to serve as the inner raceway, provided it is hardened and ground to the appropriate specifications.
6. Maintenance
Regular maintenance is essential for extending the service life of your SKF R1502-EL bearing and ensuring reliable operation.
6.1 Lubrication
The SKF R1502-EL bearing requires lubrication with compatible grease. The frequency and amount of lubrication depend on operating conditions such as speed, temperature, and load.
- Compatible Lubricant: Grease. Refer to SKF lubrication guidelines for specific recommendations based on application.
- Application: Apply grease evenly to the rollers and raceways during installation and at regular intervals.
- Avoid Over-lubrication: Excessive grease can lead to increased operating temperatures and premature bearing failure.
6.2 Inspection
Periodically inspect the bearing and its surrounding components for signs of wear, damage, or contamination.
- Check for unusual noise or vibration during operation.
- Monitor bearing temperature; excessive heat can indicate lubrication issues or damage.
- Inspect seals (if present in the assembly) for integrity to prevent contaminant ingress.
- Look for discoloration, pitting, or spalling on raceways and rollers.
