MORGOIL® Bearings & Flat Mill Products

For nearly a century, MORGOIL® bearings have been the premier oil film bearings utilized in rolling mills for the metals industry, offering unmatched reliability, efficiency, and durability. Introduced in 1932 as the first oil film bearings, MORGOIL® bearings addressed critical limitations by developing faster, more powerful rolling mills. By replacing outdated bearing technologies, MORGOIL® bearings enabled higher load capacities, greater speed capabilities, lower power consumption, and extended equipment lifespans, thus revolutionizing the metals industry. Building on this legacy of innovation, the MORGOIL® KLX® bearing enhances the performance and reliability of oil film bearings.

The KLX® bearing represents the latest innovation in MORGOIL® technology, delivering unparalleled performance and reliability for flat rolling mills. Building on the proven success of its predecessor, the KLX® offers significant advancements in load capacity, maintenance simplicity, and overall cost efficiency.

With a design that increases the width of the load zone by up to 15%, the KLX®’s thin-walled sleeve ensures superior load distribution and hydrodynamic pressure management. Its reduced part count simplifies maintenance, lowering both initial investment and operational costs. This innovation is supported by an extensive patent portfolio, highlighting a commitment to development and technological leadership.

Key Features and Benefits of MORGOIL Bearings

• Higher load capacity: enhanced bearing area accommodates heavier loads with minimal wear.
• Simplified maintenance: fewer components reduce downtime and operational expenses.
• Optimized lubrication: proprietary oil film technology ensures reliable performance in extreme conditions.
• Compact and cost-efficient design: advanced engineering minimizes material use without sacrificing durability.

KL Bearings: Proven Durability and Performance

For customers requiring compatibility with existing bearings, KL bearings remain a reliable choice, offering proven durability and performance across all applications. These bearings feature a tapered neck, keyless sleeve, Hydraulic Bayonet (HB) locking system, and DF® or HD® seals.

The tapered neck allows for easy mounting and dismounting without the need for special chocking equipment, while critical parts remain protected when off the roll neck. The sleeve’s keys are positioned outside the load zone, preventing variations in roll force. The HB lock ensures consistent and straightforward installation.
