The BTL 3020 is a standard Taper Lock bush intended for fastening pulleys, wheels, shaft couplings and other components to shafts. It is produced from grey cast iron.
Taper Lock bushes have a conical outer surface and a cylindrical inner bore with H7 tolerance including a standardized keyway (for technological reasons, some sizes with a reduced keyway). Once fixed, the component is capable of transmitting torque while being secured against axial displacement.
Typical Applications
The BTL 3020 Taper Lock bushes are used in a variety of industrial applications.
They are used to fix standard and non-standard V-belt, timing and flat pulleys, sprockets, TB hubs, shaft couplings and other components.
