This is the New patented revolutionary locking system, Z LOCK. The new series is called ZK and utilizes a tapered bore UK insert with our original Z Lock sleeve instead of a traditional adapter sleeve. The units are pre-assembled at the factory and are ready to use straight out of the box unlike traditional units that have separate inserts and adapter sleeves. The installation of ZK units is extraordinary. ZK uses on key to tighten just two set screws by hand. ZK requires no torque charts and does not affect the inner clearance of the bearing at all.
