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

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

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

The Moline Even-Lok™ 4-Bolt Non-Expansion Piloted Flange Bearing with Labyrinth Seal is engineered for demanding industrial environments where precision, stability, and advanced sealing are essential. Built with Moline’s patented Even-Lok™ concentric locking system, this bearing provides a secure 360-degree shaft grip that evenly distributes clamping forces—eliminating fretting, shaft distortion, and premature wear often associated with traditional set screw locking designs.

Non-Expansion Design

Rigid Shaft Positioning for Precision-Critical Applications

As a non-expansion bearing, this unit locks the shaft firmly in place, ensuring fixed alignment and preventing axial movement. This makes it the ideal choice for applications requiring consistent shaft positioning, including conveyors, industrial fans, HVAC systems, packaging machinery, and agricultural equipment.

Piloted 4-Bolt Housing

Accurate Alignment with Maximum Structural Strength

The precision-machined piloted flange simplifies installation and ensures exact alignment. Combined with the robust 4-bolt cast iron housing, this design delivers exceptional stability, vibration resistance, and durability—especially valuable in heavy-duty and high-speed environments.

Labyrinth Seal

Advanced Non-Contact Sealing for High-Speed and High-Temperature Conditions

The labyrinth seal sets this model apart. Unlike contact seals that wear down over time, the labyrinth seal uses a non-contact, multi-stage barrier to block dirt, dust, and moisture while minimizing friction and heat generation. This makes it ideal for high-speed rotations and elevated temperature applications where traditional seals may fail or degrade quickly.

Precision Bearing Insert

Smooth Operation and Long Service Life

Inside the housing, the precision ball bearing insert features deep-groove raceways and hardened steel balls for efficient load distribution, reduced friction, and long-lasting performance. A convenient relubrication fitting simplifies maintenance and extends operational longevity.
