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

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

The Moline Even-Lok™ 4-Bolt Expansion Pillow Block Bearing with Labyrinth Seal is designed to provide exceptional performance in high-speed and high-temperature applications. Built with Moline’s patented Even-Lok™ concentric locking system, this bearing ensures a secure 360-degree grip on the shaft, distributing forces evenly to prevent distortion, fretting, and premature shaft wear.

The expansion design allows controlled axial shaft movement, making it the ideal solution for applications where thermal expansion or contraction of the shaft must be accommodated. This feature reduces mechanical stress, maintains proper alignment, and extends the service life of connected equipment.

What sets this model apart is its labyrinth seal, a non-contact sealing system engineered for demanding environments. Unlike traditional contact seals, the labyrinth design prevents dirt, dust, and moisture from entering while minimizing friction and heat generation. This makes it the preferred choice for high-speed machinery and operations subject to elevated temperatures where standard seals may fail.

The 4-bolt cast iron housing provides maximum strength, stability, and resistance to vibration, making it suitable for heavy-duty industrial use. Inside, the precision ball bearing insert with hardened steel balls and deep-groove raceways delivers smooth operation, efficient load distribution, and reduced friction. A relubrication fitting allows for easy maintenance and ensures long-term reliability.

The Moline Even-Lok™ 4-Bolt Expansion Pillow Block Bearing with Labyrinth Seal is widely used in industrial fans, conveyors, HVAC systems, packaging machinery, and agricultural equipment. With its advanced sealing technology, rugged housing, and expansion flexibility, it delivers dependable performance in the most challenging environments.
