Moline Even-Lok™ 4-Bolt Expansion Piloted Flange Bearing w/ Labyrinth Seal

Moline Even-Lok™ 4-Bolt Expansion Piloted Flange Bearing with Labyrinth Seal

The Moline Even-Lok™ 4-Bolt Expansion Piloted Flange Bearing with Labyrinth Seal is engineered for superior performance in high-speed and high-temperature applications. Combining rugged construction with advanced sealing and Moline’s patented Even-Lok™ concentric locking system, this bearing delivers the reliability professionals demand in tough industrial and agricultural environments.

The Even-Lok™ system provides a secure 360-degree shaft grip, distributing forces evenly around the shaft to prevent fretting, distortion, and premature wear commonly caused by traditional set screw designs. Its expansion capability allows controlled axial shaft movement, reducing stress on connected components and maintaining alignment in applications where shafts expand or contract due to thermal fluctuations.

The piloted flange housing ensures accurate installation with its precision-machined pilot extension, while the 4-bolt design provides maximum stability, strength, and vibration resistance. Built from heavy-duty cast iron, this housing is designed to withstand demanding environments and heavy loads.

What sets this model apart is its labyrinth seal. Unlike contact seals, the labyrinth design creates a non-contact barrier that blocks out dirt, dust, and moisture without increasing friction or generating excess heat. This makes it the ideal choice for high-speed equipment and elevated temperature conditions, where conventional seals may fail.

Inside, the precision ball bearing insert with hardened steel balls and deep-groove raceways ensures smooth rotation, efficient load distribution, and long service life. A relubrication fitting simplifies maintenance and extends operational reliability.

The Moline Even-Lok™ 4-Bolt Expansion Piloted Flange Bearing with Labyrinth Seal is trusted in industrial fans, conveyors, HVAC systems, agricultural machinery, and high-speed processing equipment. Its combination of expansion flexibility, advanced sealing, and rugged construction ensures dependable performance under extreme conditions.
