TL型钢制拖链的主体是由链板（优质钢板镀锌）支撑板（挤拉铝合金）轴销（合金钢）等部件组成，使电缆或橡胶管与拖链之间不产生相对运动，不产生扭曲变形，链板经镀锌处理外形效果新颖，结构合理，灵巧强度高，刚性好不变形，安装方便，使用可靠，易拆装，尤其是本产品采用了高强度耐磨材料，合金钢为轴销，提高了产品的耐磨强度，弯曲更灵活，阻力更小，降低了噪音，从而可保证长时间使用不变形，不下垂。

TL型钢制拖链由于本产品外观精美，可在较大程度上增强机床设备的整体艺术美观效果，增强我国机床、机械设备在市场的竞争能力。

1.拖链可适应zui大移动速度40米/分。

2.拖链在zui大移动速度时，噪声声压级不大于68分贝。

3.拖链安全使用寿命不小于100万次（往复）。

TL series drag chains are mainly consisting of chain plate (top quality stainless steel with chromium plated),supporting board (extruded aluminium alloy) and pinshaft (alloy), etc. There is no relative motions between the cables/rubber hoses and the drag chains, giving no deforming or twists. The chromium plated chain board has very nice-looking appearance and has very rational construction and flexible and high strength. It is reliable and easy to operate, install, dismantal or assemble. It is worthwhile mentioning that the anti-wearing performance has been improved greatly due to wear resistant material and alloy pinshaft are used. The product is flexible to bending and has low resistance, giving low noises. It can be used for a very long period of time without any deformation or hanging down.

The product is nice-looking, which makes the machine tool unit nicer looking as a whole and makes the machine tools and machineries more competitive in the international market.

1. The drag chain can adapt to max. moving speed of 40m/sec.

2. When at the max moving speed, the sound pressure of noises shall not be greater than 68 db.

3. The service life of the drag chain shall not be less than 1 million times(reciprocating).
