520 FB Chain

• 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.
• 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
