This single row cylindrical roller bearing NJ306-E-XL-TVP2-C4 has a bore diameter of 30.0 mm, outside diameter of 72.0 mm, and width of 19.0 mm, with a net mass of 0.384 kg. The design features two ribs on the outer ring and one rib on the inner ring, forming a semi-locating bearing capable of accommodating axial displacement in one direction. It is fitted with a solid TVP2 cage and built to the E design for increased load rating. Limiting speed is 14200 1/min, with a reference speed of 8900 1/min. The semi-locating configuration allows the inner ring to move axially relative to the outer ring, making this bearing suitable for shaft positions requiring free axial movement while maintaining radial guidance. The C4 radial internal clearance provides increased internal clearance to compensate for thermal expansion during operation at elevated speeds or temperature differentials between inner and outer rings. The polymer TVP2 cage offers stable roller guidance and low friction characteristics, supporting reliable operation at the specified reference speed.
