4-5M387JB Wide Angle Belts are potential replacement belts. 4R-5M387, 4-5MS387 Wide Angle Belts are offered with ribs. 4-5M387 have some advantages. More specifically, neoprene compound resists fatigue, wear, ozone, and most environmental conditions. Polyester tensile cords provide length stability and superior resistance to fatigue. Ribbed backing assures lateral rigidity and relieves bending stress on small diameter pulleys. 60 degree angle gives greater support to tensile section for even load distribution.
