The revolutionary locking system "Z Lock Sleeve," which has the greatest tightening force and is the easiest and fastest in the world, is now available for the familiar pillow block.
The Z Lock Sleeve "ZK Adapter" is a revolutionary adapter sleeve that allows for easy mounting of the shaft and provides strong holding power. The new ZK series is a unit that combines FYH's original Z Lock Sleeve, which replaces the current UK tapered hole bearings and adapters. Installation is as simple as evenly tightening the cap bolt screws with a hex wrench. Compared to the conventional UK type, which required numerous tools and parts such as torque wrenches, this is overwhelmingly easier. Additionally, the ZK Adapter is shipped pre-assembled, so it can be used immediately after being taken out of the box. ■ Compatible Units ZKP: Pillow type unit ZKF: Square flange type unit ZKFL: Diamond flange type unit ZKFC: Round flange type unit with pressed-in sleeve ZKT: Take-up type unit UK: Insert bearing *For more details, please refer to the PDF materials.
