Product description
Detailed description:
These laminated blocks are made of a magnetically highly conductive material. They are composed of a combination of steel and brass laminations. For grinding, they are placed on the top pole plate of the magnetic chuck and after its activation, magnetic flux can enter freely into the workpiece. The blocks have a very stable construction, whereas individual laminations are not joined with bolts or screws. This allows modification of these laminated blocks according to individual customer requirements.
Important parameters:
- Application: Accessories
- Technology: Conventional
- Block size: from 75 x 75 mm
- Pole pitch: T4 3 + 1 mm
- Poles: Transverse/longitudinal
- Guarantee: 2 years
Use:
- Reduction of the pole plate pitch of the chuck
- Expansion of application possibilities of the chuck by clamping irregularly shaped material
Package content:
- Laminated block

Frequently Asked Questions (FAQ)
Are your products made in the Czech Republic?
Yes, the entire process – from in-house development through design, production, to final assembly and testing – takes place directly in our plant in Kroměříž. This gives us full control over quality and allows us to flexibly tailor products to specific customer requirements.
What is the difference between permanent, electromagnetic, and electro-permanent systems?
Permanent Magnets: Operate without electricity, activated mechanically by a lever. They are safe, mobile, and maintenance-free.
Electromagnets: Generate a magnetic field using coils powered by mains electricity. They possess immense strength, can clamp uneven surfaces, and allow force regulation, but require a constant power supply and backup sources.
Electro-permanent Magnets: Combine the advantages of both systems. They only require electric current for a fraction of a second for activation (magnetization) and deactivation. During operation itself, they do not need current, making them extremely safe even in the event of a power outage and preventing overheating.
Can your lifting magnets also be used for handling materials at high temperatures?
Conventional permanent magnets lose their strength at temperatures above 80 °C. However, for operations with higher temperatures, we offer special series (e.g. HOT lifting magnets) that can safely handle materials with temperatures up to 180 °C.
Why is it necessary to use a demagnetizer after machining?
Ferromagnetic materials retain residual magnetism after being exposed to a magnetic field (e.g., when clamped onto a magnetic chuck). This causes metal chips and dust to stick to the workpiece, which can damage tools or complicate further processing (e.g., painting, welding). Demagnetizers reliably remove this residual magnetism.
Do you provide service and revisions for your products?
Yes, for all our technologies, including older BUX, Walker, and Pilana brand products, we provide complete warranty and post-warranty service, repairs, overhauls, and original spare parts. We also perform mandatory periodic certifications, inspections, and load capacity testing of lifting magnets.
Do you also offer staff training?
Yes. As part of the delivery of our magnetic applications and large systems, we provide professional operator training to ensure that working with magnets is as efficient and safe as possible.
How can I contact you if I am interested in a tailored solution?
You can contact us by e-mail at info@walmag.cz, by phone at +420 573 341 641, or directly contact our regional sales managers for the Czech Republic and abroad, whose contact details can be found in the Contact section of our website.
How is heavy goods (e.g. clamping plates) delivered?
Due to the higher weight of our products, we cooperate with specialized pallet and parcel carriers who ensure safe handling.
How is the safety of lifting magnets purchased from the e-shop guaranteed?
All lifting magnets comply with the strict ČSN EN 13155 standard and operate with a safety factor of 3+. This means that in a pull-off test (the so-called Air Gap test, which simulates a real air gap/dirt in operation), the magnet can lift more than three times its declared maximum load capacity.
Where can I find user manuals and technical documentation?
Technical sheets, catalogues, and operating instructions for individual products are available either on the product's page or upon request.
