NU 307 E M1 C3 FAG 35x80x21 cylindrical roller bearing

Industrial applications

The NU 307 E M1 C3 FAG 35x80x21 cylindrical roller bearing is designed for industrial systems where high radial loads and thermal expansion must be managed without restricting axial movement.

This bearing is widely used in:

• industrial gearboxes
• electric motors operating under thermal load
• heavy-duty drive systems
• pumps and compressors
• production and processing machinery

Within the FAG cylindrical roller bearings category on simmering.pl, the NU 307 E M1 C3 model functions as a non-locating bearing, allowing axial displacement and supporting stable system operation.

Construction and design

The NU 307 E M1 C3 FAG cylindrical roller bearing combines a reinforced internal design with a durable brass cage, making it suitable for demanding operating conditions.

Key design features:

• cylindrical rollers providing line contact for high load capacity
• NU design allowing free axial displacement of the shaft
• reinforced E design for increased load performance
• M1 brass cage for maximum strength and durability
• C3 internal clearance for thermal expansion compensation

The brass cage ensures excellent resistance to vibration and heavy loads, while the C3 clearance supports stable operation in high-temperature environments.

Technical snippet:
The NU 307 E M1 C3 FAG 35x80x21 cylindrical roller bearing supports high radial loads and allows free axial displacement, with a brass cage and C3 clearance for demanding industrial conditions.

Performance advantages

The FAG NU 307 E M1 C3 bearing offers:

• high radial load capacity due to reinforced E design
• free axial displacement capability
• increased durability with brass cage
• improved thermal performance with C3 clearance
• stable operation under heavy loads and vibrations

Compared to polyamide cage bearings, the M1 brass cage provides higher mechanical strength and resistance in harsh environments.
