Moline Bearing Co Fractional Bore Size Type E 4 Bolt Flange Bearing

Moline USA-Manufactured Type E 4-Bolt Flange Bearing with Fractional Bores

Heavy-Duty Strength, Precision Fit, and American-Made Reliability

The Moline Bearing Company Type E 4-Bolt Flange Bearing with Fractional bores is engineered in the USA to deliver exceptional durability, superior load capacity, and dependable performance in the most demanding industrial environments. Designed with rugged cast iron housings and high-performance tapered roller bearing inserts, these flange units outperform standard ball bearing configurations by offering enhanced radial and thrust load capability.

Engineered for Strength and Alignment

Heavy-Duty Cast Iron Housing

Each Type E 4-bolt flange bearing features a premium Class 30 gray iron housing, chosen for its excellent strength, vibration absorption, and long-term reliability. The four-bolt mounting pattern ensures stable, secure installation, reducing misalignment and improving equipment life in high-load and high-vibration applications.

Fractional Bore Precision

Available in standard Fractional bore sizes from 1-3/16" to 4-15/16", these units provide versatile compatibility with U.S. shafting. Precision-machined components ensure easy installation, consistent alignment, and smooth operation.

Advanced Tapered Roller Design

High-Speed, High-Load Capability

Moline’s Type E assemblies utilize tapered roller bearings with factory-set internal clearances, eliminating the need for field adjustments. Compared to ball bearings, tapered rollers support significantly higher radial and axial loads, making them ideal for heavy-duty machinery.

Secure Locking Options

To protect shafts and maintain stability, these units are available with concentric clamp collars or twin set screws, offering reliable retention without excessive shaft wear.

Enhanced Sealing for Harsh Environments

Options such as the industry-preferred labyrinth seal provide superior protection against dust, moisture, and debris—extending bearing life in abrasive or contaminated conditions.

Applications

Perfect for:

• Material handling systems

• Aggregate and mining equipment

• Agriculture and grain processing

• Wastewater and municipal systems

• Conveyor drives and bulk handling machinery
