Industrial gearboxes in paper mills, steel plants, and marine drives operate under heavy loads and moderate speeds. Cylindrical roller bearings of the 52000 series deliver the radial load capacity and stiffness needed to maintain gearbox accuracy and uptime.
Types: NU (floating inner ring), NUP (fixed axial location), NJ (axial retention)
Bore Range: 30 mm – 200 mm
Materials: High‑carbon chrome steel; optional stainless steel
High Radial Load Capacity
Multi‑row designs up to 4 rows for extreme loads.
Low Friction & Heat
Optimized roller profile reduces eddy currents in geared environments.
Axial Location Options
NUP/NJ types for single or double locating arrangements.
Custom Cages
Machined brass or phenolic cages for high‑speed gearboxes.
Steel Rolling Mill Drives
Marine Propulsion Gearboxes
Cement Plant Kiln Drives
Paper Machine Speed Reducers
