INA HF1416-L564 14x20x16 Sprag Clutch Bearing

What Is the INA HF1416-L564?

The INA HF1416-L564 is a drawn cup one-way roller clutch (sprag clutch bearing) with dimensions 14x20x16 mm. It is designed to transmit torque in one direction while allowing free rotation in the opposite direction. Its compact radial design makes it ideal for applications where installation space is limited and reliable one-way torque transmission is required. Typical applications include overrunning clutches, backstopping mechanisms and precision indexing systems.

Bearing Design

The HF1416-L564 features:

• Drawn cup steel outer ring
• Needle roller clutch mechanism
• Steel springs
• Plastic cage
• Open design
• Compact radial dimensions
• One-way torque transmission

The needle rollers automatically wedge between the shaft and outer ring during rotation in the driving direction and release instantly when rotating in the opposite direction.

How Does a Sprag Clutch Work?

A sprag clutch automatically changes between driving and overrunning modes without electronic or mechanical control.

Operating principle:

• Rotating in the driving direction locks the rollers and transmits torque.
• Rotating in the opposite direction releases the rollers, allowing free rotation.
• Engagement occurs instantly.
• No manual control is required.

This design eliminates the need for additional locking mechanisms and provides highly reliable one-way drive transmission.
