2026 FK NEW PRODUCT spherical roller bearing unit

Core Innovation: Built for Extreme Demands

The 2026 FK new Spherical Roller Bearing Units is born from a deep understanding of heavy-industry challenges. We've re-engineered the spherical roller bearing core with FK bearing group proprietary steel and advanced heat treatment, delivering exceptional resistance to fatigue and impact loads. The optimized roller and raceway geometry ensure smoother operation, reduced friction, and superior tolerance for misalignment—protecting your machinery from unpredictable forces.

Sealing Redefined: Maximum Contaminant Exclusion
At the heart of the unit is our new Triple-Shield Sentinel Seal System. Combining a robust labyrinth, a high-resilience lip seal, and an innovative contaminant-ejection path, this multi-stage defense actively repels dust, slurry, and moisture. The result is dramatically extended lubricant life and bearing cleanliness, slashing maintenance frequency and downtime.

Bearing Housing Integrity & Simplified Maintenance
The housings, available in robust cast iron or high-strength ductile iron, feature a reinforced design for superior load support. Our Quick-Lock Adaptor Mounting System allows for faster, more secure installation and removal than traditional methods, and simplifies grease replenishment, ensuring even lubricant distribution throughout the bearing.

Engineered for Smart Operations
The 2026 new product is designed for the connected plant. Units are pre-fitted with Sensor-Ready ports for seamless integration of condition monitoring devices (vibration, temperature), enabling predictive maintenance strategies and preventing unplanned failures.
