Moline Even-Lok™ 4-Bolt Expansion Pillow Block Bearing

Moline M3000 Even-Lok™ Expansion 4-Bolt Pillow Block Bearing

The Moline M3000 Even-Lok™ Expansion 4-Bolt Pillow Block Bearing is engineered for maximum durability, shaft stability, and operational flexibility in the most demanding industrial and agricultural environments. Designed with Moline’s patented Even-Lok™ concentric locking system, this advanced bearing provides an even 360-degree grip around the shaft—reducing the shaft distortion, fretting, and uneven wear often associated with set screw locking mechanisms.

Expansion Design for Thermal Movement

The expansion configuration is critical for long shaft applications or systems exposed to wide temperature fluctuations. By allowing controlled axial movement, the bearing compensates for thermal expansion and contraction, reducing stress on connected components and helping maintain precise alignment. This enhances overall equipment longevity and ensures smoother, more reliable operation.

Heavy-Duty 4-Bolt Housing

Strength, Stability & Shock Resistance

Built from rugged cast iron, the 4-bolt housing offers superior structural integrity compared to 2-bolt units. Its robust design resists vibration, shock loads, and misalignment—making it the ideal choice for heavy-duty machinery and continuous-duty applications. Precision machining ensures proper fit and consistent performance across a wide range of operating conditions.

Precision Bearing Insert & Maintenance Advantages

Deep-Groove Ball Bearing Performance

Inside the housing is a precision ball bearing insert featuring deep-groove raceways and hardened steel balls that deliver smooth rotation, efficient load distribution, and reduced friction. A built-in relubrication fitting allows for easy maintenance, extending bearing life and minimizing downtime.
