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

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

The Moline Even-Lok™ 4-Bolt Expansion Flange Bearing with Labyrinth Seal is engineered to handle the most demanding high-speed and high-temperature applications. Designed with Moline’s patented Even-Lok™ concentric locking system, this bearing provides a full 360-degree shaft grip, distributing forces evenly to eliminate shaft distortion, fretting, and premature wear associated with conventional locking methods.

The expansion design is a critical advantage in systems where thermal expansion and contraction occur. By allowing controlled axial shaft movement, it minimizes stress on connected components, improves alignment, and extends the service life of machinery. This makes it especially valuable in long shaft applications or equipment subjected to varying operating temperatures.

The standout feature of this model is the labyrinth seal, a non-contact sealing system designed to keep out contaminants like dirt, dust, and moisture while minimizing friction and heat buildup. Unlike standard seals, the labyrinth seal performs exceptionally well in high-speed rotations and elevated temperature conditions, ensuring long-lasting protection without sacrificing efficiency.

Housed in a rugged 4-bolt cast iron housing, this bearing provides exceptional stability, strength, and resistance to vibration. The precision ball bearing insert with hardened steel balls and deep-groove raceways offers smooth performance, efficient load distribution, and reduced friction for reliable, long-term operation. A relubrication fitting simplifies maintenance, keeping systems running at peak performance.

The Moline Even-Lok™ 4-Bolt Expansion Flange Bearing with Labyrinth Seal is ideal for use in industrial fans, conveyors, HVAC systems, agricultural machinery, and high-speed manufacturing equipment. With its expansion capability, robust housing, and advanced sealing, it delivers consistent performance where other bearings fall short.
