Magnet rod gripper D8×H12 mm — smooth finish, 4 N holding force (TECWERK)

A Magnet rod gripper D8×H12 mm designed for precise part pick-up and positioning in assembly, inspection and light automation tasks.

• AlNiCo 500 magnetic alloy construction
• High holding force: 4 N
• Compact D8×H12 mm smooth design
• Operates up to 450 °C with h6 tolerance

Secure grip for delicate handling and repeatable pick-up

The compact magnetic gripper delivers a 4 N holding force while preserving component surfaces thanks to its smooth finish. Constructed from AlNiCo 500, the alloy combines stable magnetic properties with resistance to demagnetisation at elevated temperatures, which translates into predictable performance across production cycles. The moderate holding capacity is ideal for small fixtures, rotating inspection stations and sensitive parts where over‑clamping would risk deformation. By converting raw magnetic parameters into practical outcomes, the unit supports consistent pick-and-place tasks with minimal setup time and reduced part damage.

Built for heat and tolerance-critical processes

Designed to tolerate temperatures up to 450 °C, the gripper is suitable for heat-treatment, brazing or processes near ovens where standard magnets would lose effectiveness. The supplied specification includes a h6 tolerance and a secondary dimension 3 mm for the interface, ensuring reproducible fits into housings or dedicated mounting sleeves. Explaining the terms: h6 denotes a tight shaft-to-bore fit class that helps preserve concentricity, and the declared operating temperature indicates retained magnetic performance rather than mere thermal resistance. These attributes make the device a reliable choice when thermal cycles and dimensional precision are combined requirements.

Space-saving design for straightforward integration

With outside dimensions D8×H12 mm and a smooth execution, the component is optimised for compact assemblies and retrofit into existing grippers or end‑of‑arm toolings. The minimal footprint reduces interference in dense layouts and simplifies collision avoidance in automated cells. The polished surface minimises friction and particulation, aiding maintenance in cleaner environments, while the magnetic alloy construction reduces the need for mechanical clamps on small parts. As a small, ready-to-install magnetic element, it supports faster machine cycles and lower tooling complexity without compromising positional repeatability.

FAQ

What is the maximum holding capacity of this magnetic element?
The maximum holding capacity is 4 N for the Magnet rod gripper D8×H12 mm, suitable for light part handling and positioning tasks.

Can the gripper be used in high-temperature environments?
Yes, the TECWERK magnetic rod gripper maintains performance up to 450 °C, making it appropriate for processes with elevated temperatures.

What does the h6 tolerance mean for installation?
A h6 tolerance indicates a close fit for the interface dimension; the gripper’s specified 3 mm dimension h and h6 class enable precise, reproducible mounting in housings or sleeves.

Is the surface finish suitable for fragile components?
The smooth execution reduces surface abrasion and particulation, so the device is well suited for handling delicate parts where marking must be minimised.

Which alloy is used and why is it relevant?
The gripper is made from AlNiCo 500, an alloy known for stable magnetic properties at higher temperatures and resistance to demagnetisation, which supports consistent handling performance.
