These are the original and premium internal locking devices, fitting inside a component or hub. These units are most commonly used on applications in general engineering to transmit high torques and axial loads. Common types include 7012, 7013.0, 7013.1, 7014 and 7015. Most are available in metric series for shafts from 20 mm to 1000 mm dia. and inch sizes for shafts from 3/4” to 7.875” dia.

Derived initially from the friction spring technology these tapered rings, type 8006, pair together to form a mechanical wedge between the shaft and component being mounted. Extremely flexible in design, they can be adapted to most applications in general engineering to transmit light to medium torques and axial loads. Available in shaft sizes from 6 mm to 1000 mm.
