SKF Roller Bearing, 78mm Outside Diameter, 50mm Inside Diameter - 81210 TN

This roller bearing is a single-row component designed to support radial loads in rotating machinery. It features a closed-end configuration and a cylindrical bore to locate precisely on shafts while maintaining containment of rolling elements during operation.

Features and Benefits:

• Steel construction provides high load resistance during operation
• Non-metallic cage reduces friction and internal wear
• 300 kN static capacity sustains heavy stationary loads
• 91.5 kN dynamic rating supports continuous rotating loads
• Limiting speed of 3400 r/min enables moderate-speed applications
• Single-row arrangement simplifies axial alignment requirements

Applications

• Suitable for heavy-duty industrial drive shafts
• Ideal for conveyor rollers in material handling
• Used for gearbox intermediate shafts requiring high static load
• Can be used for pump drives with moderate rotational speed
• Appropriate for machine tool spindles with cylindrical mounting

What shaft mounting type is required for accurate fitment?

A cylindrical bore is specified and should be mounted on a straight shaft journal with the correct interference or transition fit to ensure positional stability.

How does the closed end affect maintenance procedures?

The closed end retains internal components, reducing contamination pathways and simplifying Visual inspection since rolling elements are contained.

What performance limit defines rotational endurance in service?

The bearing’s limiting speed is 3400 r/min, which should not be exceeded to avoid accelerated wear or lubricant breakdown.

Which material attributes influence fatigue resistance?

The races and rollers are MADE from steel, providing contact fatigue strength for both static and dynamic loading conditions.
