RN-0.5x47 BF RN-2.5x11.8 BF/G2

RN-0.5×47 BF RN-2.5×11.8 BF/G2

This needle roller, model RN-2.5×11.8 BF/G2, measures 2.5mm in diameter and 11.8mm in length, crafted from tough chrome steel for durability. It meets G2 precision standards, ensuring smooth operation in tight spaces.

The roller’s flat ends and high hardness (HRC60-65) make it resistant to wear, even under heavy use. Its tight roundness tolerance of 0.5µm minimises vibration for quieter performance.

With axial and radial runouts kept low (0.8mm and 0.6mm max), it fits precisely in assemblies. Ideal for compact applications like gear pumps or small engines where space is limited.

Compliant with RoHS standards, it’s a reliable choice for eco-conscious manufacturers. Interchangeable with INA models for easy replacement.
