These magnetic tensioners use a device containing a permanent magnet as a noncontact method of generating a variable resistance to rotation of the main
wheel of the tensioner, thus maintainingwire tension at the set value for longer
periods than their mechanical counterparts with greatlyreduced requirement for
adjustment.
Polished ceramic eyelets and guide rollers at each point of contact protect the insulating
enamel from mechanical damage.
The performance of these magnetic wire tensioners is exceptional given the low cost,
providing outstanding value for money.
Captive roller on tension arm is easy to thread, eliminates chance of losing wire.

General introduction
Smco magnet is suitable for machines with high magnetic requirement and good for strict working environment requirement.
Smco is a high performance, low temperature coefficient permanent magnet with its high working temperature-350 degree centigrade. When working above 180 degree centigrade, its maximum energy product bh and steady temperature are superior than ndfeb magnetic materials. Sintered smco needn't to be coated because it is difficult to be eroded and oxidized.
Features
1. Smco magnet, permanent magnet, rare earth magnet.
2. High working temperature.
3. Excellent resistance to corrosion, no coating is needed for the surface protecting.
4. Smco magnet is suitable for machines with high magnetic requirement and good for strict working environment requirement.
5. Common uses in different fields.
Surface treatments
The corrosion resistance of smco magnets is considered good. Although surface coating or plating is not generally required for smco magnets, all kinds of surface coating are also available, like nickel, zn, ni-cu-ni, gold, silver, sn, chrome, abs coating, rubber coating, ptfe(telfon) coating, stainless steel case, etc.
