Shaft Mounted Clutches – Type BSL
Inertia Dynamics features five sizes of ball bearing clutches. All sizes have ball bearing armature and field assemblies for heavy-duty applications, allowing higher shaft speeds and side loads to be achieved. All BSL clutches are shaft mounted for easy installation and operate in the same manner as our SL series clutches.
