INA Power transmission

INA needle roller freewheel clutches are components that permit motion in a single direction while blocking it in the reverse direction. They serve as retention, non-return or indexing elements in machinery where rotation must be controlled without external commands. MR Industrial Accessories LLC supplies this line and offers technical guidance to match the right part number to your application.

A needle roller freewheel from the INA HF-KF line permits rotation in a single direction while blocking movement the other way. Maintenance teams use it to stop backdriving, to serve as an anti-return device, or to couple and uncouple shafts based on which way they turn. Because the needle arrangement is compact, the unit fits into confined mounting spaces and handles moderate torque levels.

The INA HF-KF-R series is a needle roller freewheel for power transmission duty: it permits rotation in one direction while locking the other, so it can stop backdriving, time intermittent feeds and safeguard machinery. MR Industrial Accessories supplies this INA line to maintenance and purchasing teams throughout the United States and Latin America.
