DID chains are extremely strong, durable and efficient: high efficiency combined with smooth, fast reaction to load changes and high resistant to deformation and stretching. The secret behind the astonishing performance of these chains is DID's exclusive hardening process for the pins: this special treatment produces an extremely hard surface layer, while maintaining a softer inner core. These chains combine extreme impact resistance with efficient shock absorption. The specially shaped sealing rings and doubling the number of sealing points has the effect of safeguarding far more effectively against lubricant loss, and also provides optimum protection against dirt and rust.
ESJOT produces sprockets using steel meets or exceeds highest OEM requirements: the high tensile strength of this material guarantees extreme long life. The aluminium sprockets are exclusively produced with hardened aeronautical aluminium to guarantee the highest quality in conjunction with complete milling on CNC machines. All ESJOT aluminium sprockets are anodized. Special tooling guarantees a super accurate cutting surface: the material is highly condensed in the area of the teeth flanges. All sprockets are made from the best German steel to obtain a continued high quality product.
