4、pared by the Normenausschuss Maschinenbau (Mechanical Engineering Stand-ards Committee). It is based on International Standard ISO 1537 : 1975, from which it differs in the followingrespects:a) Specifications for idler sets have not been included (cf. DIN 22107).b) Additional idler lengths have been
5、 specified.c) The range of idler diameters has been reduced to include 63,5 mm, 89 mm, 108 mm, 133 mm, 159 mm,194 mm, and 219 mm.d) Types A1, B2, G1 and G2 spindle ends have been included (cf. tables 2 and 3).Idlers conforming to this standard are suitable for use with links having the dimensions fo
