Moline Bearing Co Fractional Bore Size Type E 4 Bolt Flange Bearing w/ Labyrinth Seals

Moline USA-Manufactured Type E 4-Bolt Flange Bearing with Metric Bores and Labyrinth Seals

American-Built Strength with Global Shaft Compatibility

Moline Bearing Company’s Type E 4-Bolt Flange Bearings with Metric Bores and Labyrinth Seals are proudly manufactured in the USA, delivering exceptional durability, superior sealing performance, and precision fit for global industrial applications. Designed for metric shaft diameters ranging from 30mm to 125mm, these heavy-duty flange units are engineered to support high radial and axial loads while offering industry-leading contamination protection.

Rugged Construction for Demanding Environments

Precision-Machined Class 30 Cast Iron

Each flange unit features a robust Class 30 gray iron housing, known for its outstanding strength, vibration damping, and long-term stability. Precision machining ensures proper alignment, smooth operation, and reduced wear on rotating components. The 4-bolt mounting configuration provides excellent structural support, making these units ideal for machinery subjected to continuous shock, vibration, and high loading.

High-Capacity Tapered Roller Bearing Inserts

Moline’s tapered roller bearings are factory-set for correct internal clearances, eliminating the need for field adjustments and ensuring optimal performance right out of the box. These inserts excel in high-load applications where both radial and thrust loads must be accommodated reliably.

Advanced Labyrinth Seal Technology

Superior Non-Contact Contaminant Protection

The integrated labyrinth seal system is the defining feature of this bearing. Unlike contact seals that generate friction and wear, labyrinth seals use a non-contact, multi-stage path to shield against dust, moisture, and abrasive contaminants. This results in cooler operating temperatures, extended lubrication life, and increased bearing longevity—ideal for harsh environments such as grain handling, mining, construction, and bulk material processing.

Locking Options & Interchangeability

Available locking styles include concentric clamp collars and dual setscrews, providing secure shaft retention with minimal shaft marking. Moline’s units are dimensionally interchangeable with major global brands, ensuring easy replacement and full compatibility with international equipment.

Ideal Applications

• Agricultural and construction machinery

• Grain elevators and bulk material conveyors

• Mining and aggregate processing equipment

• Industrial processing and manufacturing systems

For unmatched sealing performance, load capacity, and global compatibility, Moline’s USA-made Type E 4-Bolt Flange Bearings with Metric Bores and Labyrinth Seals deliver proven reliability in the toughest industrial environments.
