standard connecting links are used when roller chains are operated under normal conditions. for severe applications, press fit connecting links are suggested.
Keyways are British Standard Metric B S 4235. Part 1: 1972 DIN 6885 and conform to ISO recomendations with the exception of those marked, which are shallower. Where a key is to be used it should be parallel and side fitting, with top clearance. Depth of keyway is measured at the CENTRE
SITEX® gear couplings consist of two toothed hubs which are connected with one internally toothed sleeve. The sleeve is manufactured from stabilized 6.6 superpolyamide resin.
The torsional rigidity of the sleeve prevents angular speed variation. The combination of steel hubs with polyamide sleeve makes the coupling maintenance and lubrication free.
The particular toothed profile prevents contact of tooth edged with the sleeve, ensuring long life of the coupling.
TRASCO® ES is our zero backlash coupling designed to compensate for misalignment and vibration dampening for indexing applications. The compact design of TRASCO® ES makes it the right choice for all precise motion applications.
The TRASCO ES consist of two hubs, which are either made of high-strength aluminium (up to the 38/45 size) or steel (from size 42) that are connected with an elastic element.

TRASCO flexible couplings is the flexible and omocinetic coupling that assures the best performance in relation to the physical space occupied in its class. It has a very compact design and allows safe power transmision by absorbing peak loads and torsional vibrations.
Built to ASME / ANSI B29.1 standards for dimensions, interoperability, and sprocket fit, the ASME / ANSI Standard Roller Chain series also meets Diamond Chain’s rigorous internal requirements. From industry to agriculture, our Standard Series chains are designed to fit a wide variety of standard applications, and to last longer than any other manufacturer’s chain.
