Product Description

The F-612300.05. NUP-C01 is a precision‑engineered single‑row cylindrical roller bearing featuring the NUP design – a robust configuration with integral flanges on both the inner and outer rings, providing limited axial load capacity in both directions while excelling in high‑radial‑load applications. This bearing is widely used in automotive drivetrain components, gearboxes, and industrial machinery where high rigidity, low friction, and compact dimensions are essential.

Cylindrical roller bearings offer a line contact between rollers and raceways, resulting in a significantly higher radial load‑carrying capacity than ball bearings of similar size. The F‑612300.05. NUP-C01 is manufactured from GCr15 chrome steel with precision‑ground raceways and rollers, ensuring excellent dimensional stability, wear resistance, and fatigue strength under demanding operating conditions. Its open design allows for flexible lubrication arrangements, making it suitable for oil‑bath or circulating‑oil systems commonly found in automotive transmissions and differentials.

The NUP‑type construction provides a separable inner ring assembly, facilitating easy mounting and dismounting – a valuable feature for maintenance and overhaul operations. The steel cage ensures reliable roller guidance and high‑speed performance, while the precision grades (P0/P6/P5) can be tailored to meet specific OEM requirements.

Key Features & Specifications

Why Choose This Bearing?

• High Radial Load Capacity – The cylindrical roller–raceway line contact provides exceptional radial stiffness and load‑carrying ability, ideal for heavy‑duty automotive and industrial applications.

• NUP Design Versatility – Integral flanges allow the bearing to accommodate moderate axial loads in both directions, making it a compact solution for shaft positioning without additional thrust bearings.

• Separable Assembly – The inner ring assembly (with rollers and cage) can be mounted independently from the outer ring, simplifying installation, inspection, and replacement.

• Durable Material & Precision – Made from GCr15 chrome steel with controlled heat treatment, ensuring long fatigue life and consistent performance under fluctuating loads and temperatures. Precision grades P6/P5 available for higher‑speed or tighter‑tolerance applications.

Common Applications

• Automotive transmissions and gearboxes – shaft support and load‑sharing positions

• Differential assemblies – where high radial loads are prevalent

• Industrial gearboxes, pumps, and compressors

• Electric motors and generators requiring robust roller bearings

• Construction and agricultural machinery driveline components
