Stable 7200 Speed Lockstitch Sewing Machine Gear with Gleason Teeth Profile and Drawing Number LE707 A B2B Buyer's Dream

What are the characteristics of 7200 new high-speed lockstitch sewing machine gear?

The new high-speed flat seam machine gears are crucial transmission components for high-speed flat seam machines, characterized by high precision and durability. They are suitable for various industrial sewing scenarios.

Advantages

The precision of our gears is really high, with a machining accuracy reaching level 4-6. What does that mean? It means they run extremely smoothly during transmission, without any jamming at all, and the efficiency naturally goes up. Using them is just so effortless.​

Let's talk about the module range, which goes from 0.5 to 8. Don't underestimate this range; it can fit all kinds of sewing machines. No matter what model or transmission requirement the sewing machine has, you can basically find a suitable gear. It's really practical.​

The material and craftsmanship are also top-notch. We use high-strength alloy steel, which is inherently strong. Moreover, it undergoes precise forging and machining processes. After all these steps, the gears are both wear-resistant and corrosion-resistant. Even after being used for a long time, they're not easy to break and can always stay in good condition.​

As for the transmission method, it relies on the meshing of gears to transmit power. This method has a big advantage: it can support high-speed operation. Just think about it, when the sewing machine runs faster, the efficiency of sewing things is greatly improved. It's especially suitable for those scenarios that require rapid processing.
