HFZ HFK HFKL HFKP series Finger cylinder

HFZ series Finger cylinder Features: Fast and smooth motion response; excellent cost-performance ratio; body equipped with slots for magnetic switches and mountable on three sides; includes locating pin holes for high repeatability during disassembly and reassembly; moderate resistance to lateral off-center loads.
HFK series Finger cylinder Features: Integrated crossed roller guide rail offering a large contact area; superior rigidity and resistance to torsional and lateral loads compared to the HFZ series; guide rail equipped with locating pins to prevent misalignment; supports multi-directional mounting and is compatible with magnetic switches; precision locating holes ensure accuracy during disassembly and reassembly.
HFKL series Finger cylinder Features: Inherits the high-rigidity crossed roller guides of the HFK series; features an extended body and increased gripper opening/closing stroke; supports three-sided mounting and includes a positioning pin structure; suitable for gripping applications involving a wide range of workpiece sizes.
HFKP series Finger cylinder Features: Shares the same guide rail structure and rigidity as the HFK series; features an integrated dust shield at the gripper tip to prevent dust, aluminum chips, and cutting fluids from entering the guide rails; equipped with slots for magnetic switches, supports multi-directional mounting, and includes reference holes for precise positioning.

HFZ: Ball-bearing guide parallel grippers; designed for high-speed, light-load handling and assembly of small parts in standard clean environments; offers excellent cost-performance.

HFK: Crossed-roller guide high-rigidity grippers; resistant to off-center loads and torsional forces; suitable for cantilevered gripping, workpiece flipping, and medium-load applications.

HFKL: Long-stroke version of the HFK; combines high rigidity with a wider opening/closing range; ideal for handling large workpieces or parts with significant size variations.

HFKP: Dust-proof version of the HFK; features protective covers; suitable for harsh operating conditions involving dust, metal chips, or cutting fluids, such as machine tool operations and grinding processes.
