Brewer tensioners are sold without the shaft. This is the catalog of 16 plated steel shafts and studs that complete most Brewer tensioner installations. Pick the shaft (SO and NO series) that matches your tensioner model and your required overall length, or pick a stud (IS series) for setups that thread directly into the mounting frame.
Standard shafts (SO1 through SO9, NO2 through NO6) include the set collar that holds the idler component in place. Available lengths range from short configurations for compact tensioners up to longer shafts for the heavy duty BB-series. Each tensioner product page on our site lists the recommended shaft part numbers in the spec table, so you can match the shaft to the tensioner without guessing.
The stud series (IS500, IS625, IS750, and the IS1660 series) is for installations where the tensioner pivots on a threaded stud rather than a smooth shaft. Different stud configurations match different tensioner series. The IS500 is the basic 1/2 inch diameter stud; IS750 is 3/4 inch; the four-digit IS166x parts are heavier configurations for the BB heavy duty series.
If you are ordering a tensioner without already knowing which shaft, the easiest approach is to check the tensioner's product page first. The spec table lists the compatible shafts. Or call us and we will spec the pair together.
