Deep groove ball bearing NTN 6040 ZZ/2AS, Outer diameter: 310 mm | Width: 51 mm | Inner diameter: 200 mm

This deep groove ball bearing from NTN has been designed for reliable and long-lasting performance in a wide range of industrial applications. Fitted with two metal shields, it provides optimal protection against contamination while preventing lubricant leakage. Thanks to its robust design and low friction, it is ideal for systems that require precision and reliability.

Features:
The single-row ball bearing features a high-quality steel construction that ensures strong resistance to radial and axial loads in both directions. The integrated metal shields provide additional protection against dirt particles, while the standard radial clearance ensures smooth and efficient operation. Due to its ability to operate at higher speeds with moderate friction, the bearing contributes to performance optimization in various industrial environments. It is factory-lubricated with Shell Alvania S2, a high-performance multipurpose grease for extreme pressure conditions. The formulation based on lithium hydroxystearate as a thickener and high-viscosity mineral oil provides optimal wear protection and high load-carrying capacity.

Maintenance:
The bearing is lubricated for life and, thanks to the lifetime high-performance grease fill, requires only minimal maintenance. Nonetheless, regular inspections are recommended to detect potential anomalies such as increased vibration, temperature rise, or unusual noises at an early stage. During assembly and disassembly, a clean working environment is essential to avoid contamination. Proper cleaning and regular checks significantly contribute to extending service life.

Sealing:
The fitted metal shields provide effective protection against dust and medium-fine particles. Their design forms a physical barrier against contaminants and reliably retains the internal lubricant. This shielding solution reduces grease loss and ensures the optimal function of the bearing. However, in humid environments or when exposed to liquid contaminants, additional protective measures may be required.
