Moline Even-Lok™ 4-Bolt Non-Expansion Flange Bearing w/ Labyrinth Seal
Moline Even-Lok™ 4-Bolt Non-Expansion Flange Bearing with Labyrinth Seal
The Moline Even-Lok™ 4-Bolt Non-Expansion Flange Bearing with Labyrinth Seal is designed for high-speed and high-temperature applications where precision, durability, and reliability are critical. Built with Moline’s patented Even-Lok™ concentric locking system, this bearing delivers a secure 360-degree shaft grip, distributing clamping forces evenly to eliminate shaft distortion, fretting, and premature wear often caused by traditional set screw locking designs.
As a non-expansion bearing, it locks the shaft firmly in place, ensuring exact positioning and alignment. This rigidity makes it the preferred choice in systems that require stability and cannot allow axial shaft movement. Paired with the labyrinth seal, this unit excels in demanding environments. Unlike contact seals, the labyrinth seal forms a non-contact barrier, keeping out dust, dirt, and moisture while minimizing friction and heat buildup—perfect for equipment running at higher speeds or in elevated temperature conditions.
The 4-bolt cast iron housing provides maximum strength, stability, and vibration resistance, ensuring dependable operation even under heavy loads. 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 is included, simplifying maintenance and helping extend bearing performance.
Commonly used in industrial fans, conveyors, HVAC systems, agricultural machinery, and high-speed manufacturing equipment, the Moline Even-Lok™ 4-Bolt Non-Expansion Flange Bearing with Labyrinth Seal offers rugged construction, superior sealing, and shaft stability in the toughest conditions.
