Moline Bearing Co Inch 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
Moline Bearing Company’s Type E 4-bolt flange bearings with metric bores and labyrinth seals are proudly manufactured in the USA, combining precision engineering, rugged durability, and advanced sealing technology. Designed for shaft sizes ranging from 30mm to 125mm, these metric bore flange units provide robust support for high-load applications where contamination control is critical.
Each bearing unit features a premium Class 30 cast iron housing, machined to tight tolerances for excellent alignment and stability. The four-bolt mounting configuration ensures secure attachment to machinery and equipment, reducing vibration and extending service life. Moline’s tapered roller bearing inserts are factory-set for proper internal clearance, eliminating the need for field adjustments during installation.
A standout feature of these units is the integrated labyrinth seal system. Unlike conventional contact seals, Moline’s labyrinth seals use a multi-stage, non-contact design to create an exceptional barrier against dirt, water, and debris—ideal for harsh environments such as agricultural equipment, conveyors, grain processing, construction machinery, and mining operations. This advanced sealing system reduces friction and heat buildup, supporting high-speed operation and prolonged bearing life.
Moline offers both concentric clamp collar and dual setscrew locking options to accommodate diverse shaft configurations while minimizing shaft damage. These flange units are dimensionally interchangeable with most major global brands, offering seamless replacement and compatibility with international standards.
For industries requiring metric compatibility, high-load tapered roller bearings, and maximum sealing performance, Moline’s USA-manufactured Type E 4-bolt flange bearings with labyrinth seals deliver unmatched reliability and long-term value.
