Jaw Body: Weight Capacity 500-5000 kg, Clamping Force 2-50 kN

Component Specifications

Definition

The Jaw Body is the primary structural element in jaw assemblies used across various industrial applications. It serves as the foundation that houses the clamping mechanism, distributes mechanical forces, and maintains precise alignment during operation. Typically manufactured from high-strength materials, it ensures durability under repeated loading cycles while maintaining dimensional stability for accurate workpiece positioning.

Working Principle

The Jaw Body operates by converting mechanical force (hydraulic, pneumatic, or mechanical) into clamping pressure through its structural design. It provides a rigid framework that guides jaw movement along precise paths, ensuring uniform pressure distribution across the contact surface. The body's geometry determines the force amplification ratio and controls the jaw's opening/closing trajectory.

Materials

High-strength alloy steel (AISI 4140/4340), hardened to 40-45 HRC; Alternative materials include ductile iron (65-45-12 grade) for cost-sensitive applications or stainless steel (316L) for corrosive environments.
