Product Description
Easy Installation & High Torque Capacity: DPG Series Split-Clamp 45# Steel Jaw Coupling
Â
The Apexcoupling DPG Series Split-Clamp Jaw Coupling (DPG24 45# Steel / DPG23 Aluminum) is engineered for high-precision motor drives, CNC machinery, automation equipment, pumps, and general industrial transmission lines.
Designed with a two-piece split clamp hub (split-body configuration), the DPG series allows seamless radial installation and removal without disturbing connected driver or driven shafts, significantly reducing downtime during maintenance.
Â
Manufactured from high-grade 45# carbon steel with a protective black oxide finish, the coupling features H7 precision bore tolerances and high-tensile Class 12.9 clamping screws for maximum axial and rotational clamping force. Fitted with an oil-resistant polyurethane curved spider insert, the DPG coupling effectively dampens dynamic shock loads, isolates vibration, and compensates for axial, radial, and angular shaft misalignments.
Â
Core Product Advantages & Features
Two-Piece Split Clamp Design: Allows fast radial mounting and dismounting without moving connected motor shafts or machinery.
High-Strength 45# Steel Construction: Precision-machined 45# steel hubs deliver high torsional stiffness and load capacity under continuous reversing loads.
Class 12.9 High-Tensile Clamping Fasteners: Heavy-duty grade 12.9 socket head cap screws ensure maximum clamping force and slip-free torque transmission.
Precision H7 Inner Bore Tolerances: Machined within H7 tolerance limits to guarantee concentric alignment and minimal runout.
Polyurethane Spider Insert: Wear-resistant, oil-resistant elastomer insert absorbs operational vibration and cushions peak shock loads.
Custom Bore Configurations Supported: Standard keyways (K), square bores (S), hexagonal bores (F), splines (H), and custom metric/imperial shaft dimensions.
