What is NEX1 chain? The next generation chain brand which guarantees minimum 3times longer service life than normal chains. Customer satisfaction is a priority of NEX1 chain, NEX1 chain which is made of changing the material of each part, application of solid bush, newest heat-treatment method (patent no.2014-0024916). 10% increase of guaranteed breaking load, 50% decrease of chain’s elongation, and improvement of 3 times longer service life.
Feature of NEX1 Chain
SOLID BUSH Install the perfect shape of circular solid bush for minimizing chain’s elongation and improving lubrication by oil’s anti-spattering. NEX1’s Roundness is 3 times more excellent than DBC R/S. The Shape is close to the perfect circular type. Extremely maximizing the contact area with Pin and remarkably improving the wear life of chain.
PIN & BUSH Material Application of Carburizing Material Applying the newest heat-treatment method what contains improved surface hardness/deep hardness stability. Application of precision grinding: improving the surface roughness of Pin/Bush and minimizing the coefficient of friction in order to reduce the noise and extend the service life of chain.
Application brand new type of high functional dipping-oil High functional dipping-oil treatment (specialized oil for chain- mutually developed with oil manufacturer and exclusive oil for DBC) Due to improvement of lubrication and anti-rust function, the chain is maintaining the best functionally while keeping and using for a long time.
Improving precision of parts Improving precision of whole parts’ molds Equalizing the length of chain by Precision parts mating (it achieve optimization by distributing load equally When it’s operating in paralle)
Using self-assembly mechanism Using self-assembly mechanism Meeting the accurate delivery date by reducing process time
Improvement of breaking strength through the most appropriate heat-treatment method
Improving fatigue strength
Improving wear-prevention of chain
Precision transmission chain running on sprockets, for drives and machinery.

What is DBC SUPER Chain?; Enhanced tensile strength 10%, Fatigue strength 40%. As SUPER series of DBC is precise chain with high fatigue strength and tensile strength, Breaking Load about 10% and Maximum allowable load (fatigue strength)…
A-Type Leaf Chain (Standard); Appearance and thickness, an external diameter of plate are the same as Standard roller chain on marked same pitch.
B-Type Leaf chain (Heavy series); The plate exterior is identical to that of the ANSI standard Roller Chain, but the plate thickness and the pin external diameter are identical to those of the Roller Chain One size larger.
LL Series (Light Duty, ISO R606 Recommendation, European Standard); Appearance and thickness, an external diameter of plate are the same as Standard roller chain on marked same pitch.
