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

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

Engineered for High-Speed, High-Temperature, and Heavy-Duty Performance

The Moline Even-Lok™ 4-Bolt Expansion Piloted Flange Bearing with Labyrinth Seal is built to deliver exceptional reliability and longevity in demanding industrial and agricultural applications. Designed for equipment that operates at high speeds or elevated temperatures, this bearing combines rugged construction with advanced sealing and Moline’s patented Even-Lok™ concentric locking system for unmatched performance.

Even-Lok™ Concentric Locking System

Secure 360° Shaft Grip for Maximum Stability

Moline’s Even-Lok™ technology provides a uniform, full-circle shaft grip that eliminates fretting, shaft distortion, and premature wear commonly associated with traditional set screw locking. By distributing clamping forces evenly, it ensures smooth, vibration-free operation—even in high-speed or high-load environments.

Expansion Design for Thermal Movement

Maintains Alignment & Reduces Mechanical Stress

The expansion-style bearing insert allows controlled axial movement, accommodating thermal expansion and contraction. This reduces stress on shafts and connected components, improves alignment, and extends equipment life—especially in systems exposed to extreme temperature fluctuations.

Piloted 4-Bolt Housing

Precision Alignment with Rugged Durability

The precision-machined piloted extension ensures accurate alignment during installation, while the 4-bolt cast iron housing provides superior rigidity and vibration resistance. Built to withstand demanding conditions, it delivers long-term stability under heavy loads and continuous operation.

Labyrinth Seal

Non-Contact Protection for High-Speed Applications

The labyrinth seal creates a multi-stage, non-contact barrier that blocks contaminants such as dust, dirt, and moisture while minimizing friction and heat buildup. This makes it ideal for high-speed fans, conveyors, and machinery operating in elevated temperature environments.
