 Double Idler Sprockets

B-type W (double) idler sprocket holds tension at the appropriate level during roller chain transmission. When using the B-type drive sprocket and driven sprocket wheel, design can be made easier by using the same B type W idler. This product also has excellent load bearing capacity since it uses two bearings.
