RAILKO NF22 brake linkage bushes are used within freight and passenger vehicles in the articulation points of the braking system. It is important to ensure the material has a low water swell and thermal expansion, avoiding seizing issues on the pin shaft which can affect the wagon braking mechanism.
RAILKO NF22 reinforced composite bushes are proven to lower noise by up to 13dB (A), compared with steel bushes. RAILKO NF22 composite bushes provide protection to pins, shafts and housings against costly wear. The brake bushes have a very low water swell and thermal expansion, which enables tighter running clearances and longer bearing life.
