Moline Even-Lok™ Expansion Flange Bearing

Moline Even-Lok™ Expansion Flange Bearing

Advanced Concentric Locking for Superior Shaft Retention

The Moline Even-Lok™ Expansion Flange Bearing is engineered to deliver secure shaft support, smooth operation, and long-lasting reliability in demanding industrial and agricultural applications. Featuring Moline’s patented Even-Lok™ concentric locking system, this advanced bearing ensures a full 360-degree grip around the shaft. By distributing clamping pressure uniformly, the Even-Lok™ mechanism eliminates shaft distortion, fretting, and uneven wear—common issues associated with traditional set screw locking designs.

Expansion Design for Thermal Flexibility

Controlled Axial Movement

The expansion-style bearing insert accommodates controlled axial shaft movement, making it ideal for long shaft systems or machines exposed to temperature variations. This ability to absorb thermal expansion and contraction reduces stress on connected components, improves alignment retention, and significantly extends overall equipment life.

Housing Options for Versatile Installations

Pilot Flange and 4-Bolt Configurations

Moline offers the Even-Lok™ Expansion Flange Bearing in two robust housing styles:

• Pilot Flange Housing – Compact, self-aligning, and ideal for space-restricted installations where precision alignment is essential.

• 4-Bolt Flange Housing – Provides maximum strength, surface stability, and vibration resistance for heavy-duty or high-load applications.

Both housings are manufactured from durable cast iron to withstand harsh environmental conditions and rigorous operating demands.

Precision Bearing Insert for Smooth Operation

Deep-Groove Raceways & Hardened Steel Balls

At the heart of the assembly is a precision ball bearing insert engineered for efficient load distribution, reduced friction, and consistent performance. The deep-groove raceway design enhances smooth rotation, while hardened steel balls ensure durability under continual use. A built-in relubrication fitting simplifies maintenance and promotes long service life.
