1.1 Regular Roller Chains. These chains are created for general usage.
1.2 POWERFUL Chains. These chains possess higher tensile strength and greater fatigue strength.
1.3 Lube-Free Chains. These chains have longer use life than standard chains without lubrication.
1.4 Environmentally Resistant Chains. Chains with special corrosion resistance.
1.5 Specialized Chains, Type 1. For particular applications.
1.6 Specialized Chains, Type 2. For general designs.
Within these six groups, there are several types of chains available
The drag chain test made out of our equipment certifies the cable capability of bending along the chain path
The movement patterns are run through the classic trapezoidal course profile for reflecting the stress placed on the cable in the Customer’s application. The cable is usually subject to bending motion through trolleys that operate at high velocity on precision guides, driven by cogged belts. It is possible to test up to 4 chains simultaneously with the same tools, with a pulling capacity up to 3000 N
The test parameters (traversing distance, acceleration time, maximum speed and number of cycles) are adjustable and settable through a touchscreen panel. Through the test routine, the cables are examined by an exterior measuring system: in the event of cable break, the corresponding counter stops and the machine continues to operate and test the rest of the samples until their last break (this option can be modified according to the requirements).
All characteristics could be personalized according to Customer requests.
Our worm gear models cover an array of applications. We demonstrate our years of encounter and advanced of capability by producing more than 1 million worm gear models every year in-house, the majority of which are manufactured according to custom specs.
Our 
catalog of worm equipment sets good regular have diameters ranging from 20 to 135 mm and axial distances of 17 to 80 mm. In addition, you can expect custom worm gear models with diameters of up to 300 mm and center distances of up to 210 mm.
The catalog of worm gear sets can generally be supplied (from our) warehouse in a wide selection of axial distances and gear ratios with fine examples of differentiation. We can also calculate and generate customer-specific axial distances and equipment ratios at the plant. We prefer to create worm gear pieces for right-handed users, but these sets can be designed for left-handed users on request.
We perform all major soft and hard machining measures in-house, including annealing inside our own ovens. Because of extensive production depth, we are able to execute, even highly complex, machining tasks exactly according to customer expectations and in the highest quality. Learn more about it here.
