V Class Oilfield Chain
Tsubaki roller chain for oil well machinery
Tsubaki "V" Class roller chains are designed and manufactured for oil well rig drives used in the most severe conditions where high speed and heavy shock load are expected. These chains are manufactured according to ANSI specifications.
- Superior impact resistance
The pin surface is carburized and hardened with Tsubaki heat-treating techniques for superior impact resistance. This results in greater breaking strength and increased chain impact strength as compared to ANSI standard chains.
- Greater fatigue resistance
Pin holes in link plates are ball drifted after heat-treatment for greater fatigue strength. A 30% increase in chain life compared with ANSI standard chains is the net result of this procedure.
- High speed durability
Rollers, precisely manufactured, are shot-peened after heat-treatment to give them superior fatigue life and high speed durability.
