Single-row ngulr-contct bll berings Single-row ngulr-contct bll berings Definition nd cpbilities Alwys mounted in opposition to nother bering of sme type, they offer high mounting stiffness, especilly when preloded. Definition Cge Stndrd dimension berings re equipped with either metl cge or synthetic mteril cge. In the ltter cse the mximum continuous operting temperture is 120 C or 248 F (150 C pek or 302 F pek). Lrge-sized berings re equipped with mchined brss cge. Contct ngle Angulr-contct bll berings of norml precision hve contct ngle of 40 (suffix B). Some berings hve contct ngle of 30, in which cse the bering reference does not hve the B suffix. Cpbilities Lod nd speed These berings re designed to: withstnd combined lods with predominnt xil component F / F r 1 withstnd lods in one direction only (they must be mounted in opposition with berings of the sme type) ccept reltively high speeds of rottion Mislignment Assembly mde up of single bering Slight mislignment between the shft nd housing is cceptble. The vlue depends on the ssembly clernce: from 0.10 to 0.15 if the ssembly clernce is 0.06 in the cse of preloded ssembly. Assembly mde up of two berings In this cse, the ssembly is similr to double-row bll bering nd the cceptble mislignment vlues re very low, in the rnge of 0.06. 232

Series 72 73 Vrints Berings for universl mtching (suffix BG) The berings in the 72... BG, 73... BG series cn be ssembled in pirs to form single pillow block. They re supplied individully nd cn be mtched in either n X, O or Tndem rrngement. Arrngement Chrcteristics Fce-to-fce or X rrngement (type DF) This rrngement constitutes single ssembly. Another bering is needed to form the second pillow block of the shft. Bck-to-bck or O rrngement (type DB) Good rigidity under tilting torque. This ssembly cn in some cses ensure shft retention on its own thnks to the distnce between the lod ppliction point. Tndem (type DT) For very high xil lods but in one direction only. This rrngement constitutes single ssembly; nother bering must be mounted in the opposite direction to form the second ssembly of the shft. Other vrints cn give ssemblies with greter or lesser mount of prelod (suffix BGL or BGO); they requires usully prior technicl study. On request these berings re supplied with mximum runout mrk on the inner ring. When the two berings re ssembled, their respective mrkings must be ligned. 233

Single-row bll berings cn be supplied on request with ll or specified chrcteristics in tolernce clsses 6 nd 5 (e.g. bore or xil run-out in tolernce clss 6). Axil clernce on ssembly with two seprte berings These berings re lwys ssembled in opposition, nd their internl clernce is determined by djusting the xil clernce of the shft t the time of ssembly. For informtion, the reltionship between the xil clernce nd the rdil clernce is given by the formul: J r = 0.83 J These berings cn be instlled preloded if needed to increse the xil rigidity of n ssembly. The mximum speed of rottion is then reduced, nd depends on the vlue of the prelod. Consult SNR. The im of djusting n ssembly comprising two ngulr-contct bll berings is to djust the xil clernce, tht is to sy the initil reltive position of the inner rings with respect to the outer rings, so tht the berings re positioned in the best possible operting conditions, while t the sme time stisfying the specific ssembly requirements (precision of rottion, rigidity, vibrtion, heting, etc.). The djustment is defined either by n xil clernce or prelod. The optimum prelod of n ssembly is determined ccording to the ppliction specifictions (rigidity, precision, temperture, vibrtion, etc.). Whtever the cse, consult SNR. The ssembly nd djustment conditions ffect the clernce of the ssembly. Type BG berings usully hve reduced residul clernce fter ssembly. 234

Axil clernce of BG ssembly The clernce of n ssembly (X or O rrngement) is defined by the protrusion d e of one ring with respect to the other. chrge d e d e Bering bore Protusion vlue from to in µm 10 30 8-19 35 50 8-20 55 80 11-23 85 110 17-29 115 180 20-32 The xil clernce of the ssembly is clculted s follows: men theoreticl xil clernce: 2 d e rdil reduction of clernce due to interference fits: men xil clernce of the ssembly: Δ J r J = 2 d e - ( Δ J r / 0.83 ) By pplying this formul to the clcultion of probble tolernces, one obtins minimum clernce vlue close to zero with conventionl ssembly (interference fit on shft with j6/k6 tolernce nd clernce fit in the housing with n H7/J7 tolernce). 235

Single-row ngulr-contct bll berings 4-point ngulr-contct berings Definition nd cpbilities 4-point ngulr contct berings ccept xil lods in both directions. They re often ssocited with rdil contct bering. Definition The design of this bering results from the theoreticl superposition of the two sections of mtched ngulr-contct berings in n X or O rrngement. The curvture of the rcewys is consequently ellipticl nd displys two loding lines (contct ngle 35 ) which gives four points of contct on the blls. The two-prt inner ring cn be filled with more blls thn rdil bll berings. Cge The cge is usully mde in mchined brss centred on the inner or outer ring, joining the ring of blls to the outer ring. Cpbilities Lod nd speed These berings re designed to: withstnd combined lods with predominnt xil component F / F r 1.25 withstnd xil lods in both directions ccept reltively high speeds of rottion Mislignment The construction of these berings limits them to very smll mislignment vlues, in the rnge of 0.06.

Rdil clernce The reltion between the xil clernce J nd the corresponding rdil clernce J r cn be clculted using the following pproximtion formul J r = 0.7 J Design criteri Bering life Equivlent dynmic lod P = F r + 0.66 F if F / F r 0.95 P = 0.6 F r + 1.07 F if F / F r > 0.95 Equivlent sttic lod P 0 = F r + 0.58 F Instlltion/ssembly criteri The xil clernce of this bering is determined for conventionl mounting on rotting shft with n interference fit j6 or k6 type. The fit of the housing must be loose (H7), hence the need to prevent the ring from rotting in certin pplictions (version suffix N2). The two inner hlf-rings must be held tight xilly ginst shoulder. In most pplictions, this bering is considered like single ssembly. It cn sometimes be used like double ssembly plying the role of two berings, thnks to the distnce between the lod ppliction points.
