4B sprockets and trailing wheels are manufactured from high grade heat treated steel to a minimum hardness of 57 HRC.
Each piece is machined to size with appropriate bore and keyway specific to each customer's application.
Smooth and segmental trailers have different hub widths as noted (WB2 & WB3).
4B offers any bore size to suit your requirements; consult with our engineers for recommended shaft diametre.
216NA and 260NA sizes are available; contact 4B for more information.
4B's drop forged chain is made of special heat treated high grade alloy steel, case hardened to Rockwell C57-62 with a ductile core hardness of Rockwell C40.
4B's superior heat treatment technique provides the optimum forged chain link with a more resilient ductile core for shock resistance, and an extremely hard exterior surface for superior wear resistance.
4B forged chain links and pins are also available in all grades of stainless steel.
