Magnetic rod gripper D20×H25 mm — smooth, 40 N holding force (TECWERK)

The Magnetic rod gripper D20×H25 mm smooth is a compact magnetic clamp designed for precise positioning and temporary holding of small ferrous components in production, assembly and inspection tasks.

• Smooth AlNiCo 500 surface
• Compact Ø 20 mm design
• Holding force 40 N
• Temperature resistance up to 450 °C

Secure small-part holding with measurable performance

The compact format provides a predictable holding characteristic: a cylindrical body with Ø 20 mm and a total height of 25 mm gives a stable contact area for small fixtures while keeping the footprint minimal. The specified 40 N holding force describes the peak pull capability under standard test conditions and translates into reliable short-term fixation for light assemblies, jigs or pick-and-place operations. This measured value supports process planning and reduces trial-and-error during fixture design.

Material selection for thermal stability and magnetic consistency

Built from AlNiCo 500, the magnet core offers stable magnetic properties at elevated temperatures and good demagnetisation resistance compared with standard ferrite magnets. AlNiCo 500 retains useful magnetic strength where heat is present, allowing operation up to 450 °C without rapid loss of performance. For production environments that include heat cycles or near-heat processes, this material choice reduces the need for frequent replacement and maintains holding performance over time.

Precision fit and installation advantages

Additional geometric data includes a dedicated dimension h: 5 mm with a h6 tolerance class; this defines a close-fitting datum for press or slip fits and ensures repeatable positioning in housings or tool plates. The h6 tolerance indicates a tight shaft fit commonly used in precision assemblies, reducing play and improving repeatability in repetitive operations. Clear dimensional control lowers setup time and contributes to consistent assembly quality.

Gentle contact and versatile application range

The smooth finish prevents unnecessary marking on mating parts and is therefore suitable for short-term contact with prepared surfaces. The combination of compact geometry and thermal resistance makes the component well suited to fixture points, temporary tacking in welding pre-assembly and sorting tasks where gentle magnetic support is required. The TECWERK magnetic rod gripper balances low profile design with practical holding capacity for everyday workshop and small-scale industrial tasks.

FAQ

What types of parts are suitable for magnetic holding? The magnetic rod gripper is designed primarily for ferrous components and supports temporary fixation of steel parts and similar magnetic materials.

What is the maximum operating temperature? TECWERK specifies an operating temperature up to 450 °C for this magnetic rod gripper, reflecting the thermal resilience of the AlNiCo 500 material.

What does the h6 tolerance mean for installation? A h6 tolerance indicates a close shaft fit; it ensures a snug installation with minimal play when the 5 mm h dimension is used as a locating feature.

How strong is the grip in practical terms? The device provides a maximum holding force of 40 N, suitable for short-term holding and light fixture duties rather than heavy lifting.

Will the finish mark delicate surfaces? The smooth execution reduces point marking and is intended for short-term contact where minimal surface impact is required.
