NU330 single row cylindrical roller bearing details

NU330 is a single row cylindrical roller bearing with two fixed ribs on the outer ring and a smooth inner ring. This design allows the shaft to move axially relative to the housing within a certain range.

NU330 cylindrical roller bearing is very rigid, can support high radial load, and because of the cage, it is more suitable for high speed than the full complement design. The bearing roller set with the suffix E is larger and is designed for ultra-high load carrying capacity.

This bearing is detachable, so it is easier to install or remove. The two bearing rings therefore have an interference fit.

NU330EMC3 the size parameters refer to NU330 bearing, copper cage, C3 clearance, which can reduce the number of parts around the bearing and reduce the cost of the overall structure of the pulley. Mechanical bearing NU330 EMC3, one of the high-quality NU330 series models, is in the production field , Wide range of uses, our company has a wealth of NU330EMC3 bearing inventory. The characteristics of use are: high transmission efficiency, impact resistance of the lubricating film, bearing radial load and bidirectional axial load, pre-filled with a proper amount of grease, and good anti-wear performance.
