SpeedMaster Chain from Tsubaki is the answer for high-speed applications. SpeedMaster features carbon through-hardened plates.
The pins are made of a specially treated alloy material. The surface of the pin is extra hard – improving wear resistance. The pins are
quad riveted to better resist side force impact. The chain features a greater contact area between pin and bushing which results in less
contact wear pressure and longer wear life. Shepherdʼs crook style cotter pins make for easymore assembly of connecting links. Tsubakiʼs
patented ring coining process generates unsurpassed connecting link strength. Depending on speed of the application and operating
conditions (e.g. lubrication), users can expect between 2 and 6 times greater wear life compared to ANSI Standard RS Roller Chain.
Note: Horsepower ratings for SpeedMaster chain are same as for identical size of Tsubaki RS Standard ANSI roller chain less
