Moline Bearing Co Fractional Bore Size Expansion E1000 4-Bolt Split Pillow Block Bearing

Heavy-Duty Support with Built-In Thermal Flexibility

The Moline Expansion E1000 4-Bolt Split Pillow Block Bearing with fractional bore sizing is engineered for precision support and axial shaft movement in industrial environments where thermal expansion must be managed. This expansion-style pillow block bearing is designed to absorb linear shaft growth without inducing stress on equipment, extending bearing and shaft life in high-heat or long-shaft applications.

Expansion Insert Design

Accommodates Thermal Shaft Movement

The floating bearing insert allows controlled axial shaft movement, preventing bearing misalignment or shaft binding during temperature changes. It’s ideal for:

• Long conveyor shafts

• High-temperature processing lines

• Equipment with thermal cycling

Fractional Bore Compatibility

Built to fit standard inch-size shafts, this bearing is a natural fit for North American machinery, reducing the need for custom modifications.

Rugged 4-Bolt Split Housing

Durable. Serviceable. Stable.

The 4-bolt design provides maximum housing stability under heavy loads and vibration. The split housing simplifies bearing inspection and replacement, allowing for quick shaft-in-place service without complete disassembly.

Materials include:

• Cast iron or ductile iron housings

• Precision-machined surfaces for tight tolerances

Applications

• Mining conveyors

• Power transmission systems

• Material handling lines

• Industrial fans, kilns, and dryers

Why Choose Moline’s Expansion E1000 Pillow Block?
