Moline Even-Lok™ 4-Bolt Expansion Pillow Block Bearing with Standard Double Lip Contact Seal
The Moline Even-Lok™ 4-Bolt Expansion Pillow Block Bearing with Standard Double Lip Contact Seal is engineered for demanding industrial and agricultural applications that require exceptional shaft support, durability, and environmental protection. Featuring Moline’s patented Even-Lok™ concentric locking system, this advanced bearing provides a uniform 360-degree grip around the shaft, reducing fretting, distortion, and wear commonly associated with set screw locking mechanisms.
Expansion Design for Thermal Movement
The expansion configuration allows controlled axial shaft movement, making this bearing ideal for long shaft systems or equipment exposed to fluctuating temperatures. By accommodating thermal growth and contraction, the bearing helps maintain alignment, reduce mechanical stress, and extend overall equipment life.
Enhanced Protection with Double Lip Contact Seal
Reliable Sealing in Harsh Environments
The standard double lip contact seal provides superior protection by keeping contaminants—such as dust, dirt, and moisture—out of the bearing while retaining lubrication inside. This dual-seal design ensures smoother operation, longer service intervals, and better performance in dirty or abrasive conditions commonly found in industrial and agricultural settings.
Heavy-Duty 4-Bolt Construction
Maximum Strength & Stability
The rugged 4-bolt cast iron housing delivers exceptional strength, shock resistance, and stability. Its precision-machined surfaces ensure proper fit and dependable bearing alignment, even under heavy loads or vibration. Inside, the precision ball bearing insert with deep-groove raceways and hardened steel balls offers smooth rotation, efficient load distribution, and reduced friction.
