Excellent environmental resistance
In addition to absorbing vibration and shock, they have excellent resistance to cold, heat, and oil, enabling their use in punishing environments.
Clamping hubs
When coupling a spline shaft (pump shaft) and cylinder hub, a clamping hub can be provided to allow complete locking in place by means of center lock action. We can design to meet your needs, so please contact us for details.
