The 11891 rim has a .325" pitch and 8 teeth. Oregon rims offer the ultimate cutting system performance by providing a smoother cutting experience and less chain wear when compared to spur sprockets. The rim's radial port design uses centrifugal force to throw off sawduck and debris. Wear-depth indicators show when it's time to replace the rim. Replace the rim every two chain loops. This rim works with certain Dolmar, Husqvarna, Jonsered, Makita, McCulloch, Olympyk, Partner, Pioneer, Poulan and Stihl chainsaw models. Check the fit guide to see if this rim works with your saw.
