Moline Even-Lok™ Expansion Flange Bearing

Moline Even-Lok™ Expansion Flange Bearing

The Moline Even-Lok™ Expansion Flange Bearing is engineered to provide secure shaft support, long service life, and superior reliability in demanding applications. Featuring Moline’s patented Even-Lok™ concentric locking system, this bearing ensures a full 360-degree shaft grip. By distributing clamping forces evenly, the Even-Lok™ design prevents distortion, fretting, and premature shaft wear—problems commonly associated with traditional set screw locking methods.

The expansion-style bearing is designed to allow controlled axial shaft movement, making it ideal for long shaft applications or systems exposed to significant temperature fluctuations. By accommodating thermal expansion and contraction, the bearing reduces stress on connected components, helps maintain proper alignment, and extends equipment life.

Moline offers the Expansion Flange Bearing in both pilot and 4-bolt housings, providing flexibility for different applications. The pilot flange version is compact and precision-aligned, perfect for space-restricted areas, while the 4-bolt housing provides maximum strength, stability, and resistance to vibration for heavy-duty operations. Both options are made from rugged cast iron, ensuring durability and resistance to wear in harsh environments.

At the core of the unit is a precision ball bearing insert with hardened steel balls and deep-groove raceways. This design provides efficient load distribution, reduced friction, and smooth operation. Each unit is also equipped with a relubrication fitting, simplifying maintenance and extending bearing service life.

The Moline Even-Lok™ Expansion Flange Bearing is widely used in conveyors, agricultural machinery, HVAC systems, packaging equipment, and material handling systems. Its combination of advanced locking technology, expansion capability, and durable housing makes it a trusted solution for both light and heavy-duty applications.
