This is the top of the line; the strongest, most durable sealed chain that we offer
FB = Fine Blanking, an incredibly precise manufacturing process that yields perfectly cut links
Tight tolerances make the plate, pin, and bushing union accurate and strong
Due to the accuracy of the cuts and the use of stronger alloyed steel, the FB has our highest tensile strength rating, nearly 8,000 lb. (EU: 3628,74 kg)
Special sealing rings are chemically treated to gain strength and reduce friction
The FB treatment allows the O-rings to be impregnated with grease
FB rings are stronger and more durable than X-rings, with significantly less friction
Gold links and rollers, silver inner plates, pins and bushings
