Moline Even-Lok™ 4-Bolt Non-Expansion Pillow Block Bearing with Labyrinth Seal
Engineered for High-Speed, High-Temperature, and Heavy-Duty Demands
The Moline Even-Lok™ 4-Bolt Non-Expansion Pillow Block Bearing with Labyrinth Seal is specifically designed for applications where secure shaft retention, advanced contamination protection, and long-lasting performance are essential. Built with Moline’s patented Even-Lok™ concentric locking system, this bearing provides a true 360-degree uniform grip around the shaft, eliminating distortion, fretting, and premature wear common in traditional set screw–locked bearings.
Non-Expansion Design for Fixed Axial Positioning
Precision Alignment for Critical Equipment
The non-expansion (fixed) configuration prevents axial movement of the shaft, maintaining exact positioning and ensuring consistent alignment. This makes the bearing ideal for machinery where rigid support is required, such as industrial fans, rotary equipment, conveyors, and precision-driven systems.
Advanced Labyrinth Seal
Non-Contact Protection for Harsh, High-Speed Conditions
The labyrinth seal elevates performance by forming a non-contact barrier that blocks contaminants—including dust, dirt, and moisture—from entering the bearing. Unlike contact seals, the labyrinth design reduces friction and heat buildup, making it perfect for high-speed and high-temperature operation. This sealing system extends bearing life while maintaining smooth, efficient performance under demanding conditions.
Heavy-Duty 4-Bolt Cast Iron Housing
Superior Strength and Vibration Resistance
The rugged 4-bolt cast iron housing provides maximum durability, stability, and vibration resistance. Inside, a precision deep-groove ball bearing insert with hardened steel balls ensures efficient load distribution, reduced friction, and reliable long-term performance. A convenient relubrication fitting allows easy maintenance and supports extended service life.
