HarvesterLok ® Friction Hub
Keyless Sprocket System for Most Harvester Applications
HarvesterLok®
The keyless frictional locking device family provides a high capacity, zero-backlash shaft-tohub or coupling connection by means of a mechanical interference fit. Boasting exceptional
concentricity and ability to transmit bending loads, as well as no axial movement during
installation, the friction hub circumvents the shortcomings of traditional connection methods
like shrink fits and keyways. These advantages also result in reduced shaft material and more
lenient tolerances, which directly translates to less maintenance time and cost.
FEATURES
BENEFITS
Uniform Pressure Distribution
• Eliminates distortion and warping
Fittings for Smaller Shafts
• Allows for broader application
Keyless Hub
• Complete axial and radial adjustment,
even over existing keyways
• No keyways failures, seize ups or shaft
failures because of worn keyway
Hex-head Set Screws
• Simple and quick installation,
adjustment, and removal in the field
No Space Between Sprocket and Shaft • True zero backlash shaft-to-hub connection
The sprocket should be aligned to the drive shaft to prevent damage to
the chain, bar, and sprocket. Mount the harvester bar to the machine.
