Moline Even-Lok™ 2-Bolt Expansion Pillow Block Bearing with Labyrinth Seal
The Moline Even-Lok™ 2-Bolt Expansion Pillow Block Bearing with Labyrinth Seal is engineered for high-speed, high-temperature, and contamination-prone environments where dependable shaft support and superior sealing performance are essential. Featuring Moline’s patented Even-Lok™ concentric locking system, this bearing delivers a true 360-degree grip around the shaft, eliminating fretting, distortion, and premature wear commonly associated with set screw locking mechanisms.
Expansion Design for Thermal Shaft Movement
The expansion configuration allows controlled axial shaft movement, making it the ideal choice for applications where thermal expansion and contraction must be accommodated. This capability helps maintain proper alignment, reduces internal stress, and prolongs the life of connected equipment—critical advantages in high-speed and continuous-duty operations.
Advanced Labyrinth Seal Technology
Non-Contact Sealing for High-Speed Applications
The labyrinth seal provides outstanding protection in demanding environments. Its non-contact design forms an engineered pathway that blocks dirt, dust, and moisture without creating friction or heat buildup. This makes the bearing highly suitable for elevated temperatures, high speeds, and applications where traditional contact seals may wear out prematurely. The labyrinth system ensures clean operation, reduced maintenance, and long-lasting durability.
Rugged Construction & Precision Bearing Insert
Strength and Stability
The heavy-duty 2-bolt cast iron housing is built to withstand vibration, shock loads, and misalignment while providing stable shaft support. Inside, the precision-engineered ball bearing insert with hardened steel balls and deep-groove raceways ensures efficient load distribution, reduced friction, and smooth performance. A relubrication fitting supports ongoing maintenance and extends service life.
Applications & Key Benefits
Ideal for conveyors, industrial fans, HVAC systems, packaging lines, and high-speed agricultural machinery, this Even-Lok™ bearing offers premium performance in tough environments.
