[h=3]Hi all,[/h] I am new and need an advice about shaft and housing chamfer angles ? Medias.ina says 10-15 degrees angle for ease of bearing instalation (it seems small to me). Also find a lot of recomendations for 15 to 30 degrees if sealings are to be instaled. However I see a lot of 1mm x 45 degrees chamfers over the internet. What angles are used in practice ? My second questions is what will be the appropriate fit for Drive Shaft and Hub ? Shaft d- 35mm j5 not shure about the Hub bore ??? Both are SS, I have a key 10x8x50 mm (DIN 6885A) and moment - 200 Nm looking for ease of installation without sacrificing function. Should I look for Locational clearance fit or Locational transition fit ?
