1 Intoduction Tpeed olle eings Tpeed olle beings, due to tpeed cewys nd olles, hve the cpbility to suppot vious combintions of thust nd dil lods. The thust lod cpbility vies with the cup ngle; the gete the cup ngle the gete is the tio of thust to dil ting. Tpeed olle beings e mnufctued by NTN- owe in mny diffeent seies to meet vious ppliction equiements. All the beings in seies hve the sme intenl constuction nd lod cying cpbility. Ech seies lso include numbe of cones which diffe only in boe size nd/o cone dius. Any cone within given seies my be combined with ny cup in the sme seies nd ech combintion will hve the sme lod ting s discussed lte in this ctlog. Flnged Single ow eings (TSF Type) The TSF type being consists of single cone nd single cup flnged on its outside dimete. The cup flnge is mounted ginst the side fce of the housing eliminting the need fo shoulde inside the housing to suppot thust lods. This fetue pemits though-boing of the housing to chieve moe ccute lignment fo the cup sets. In othe espects, the flnged cup beings e simil to the TS type being descibed peviously. NTN-owe mkes vious types of single ow, two ow nd fou ow tpeed olle beings consisting of viety of cone nd cup configutions s descibed below: Single ow eings (TS Type) The TS type being is the most commonly used tpeed olle being. It consists of single cone nd single cup. The TS type is vilble in vious boes, widths, outside dimetes, nd cup ngles to povide nge of envelope dimensions nd dil nd thust lod tings to meet vious ppliction equiements. The TS type being with steepe cup ngle cn suppot gete thust lod thn dil lod. ouble Two ow eings (TO Type) ouble cup two ow beings e mnufctued in mny of the sme seies s single ow tpeed olle beings. The TO type being consists of double cup hving one piece constuction with two cewys, nd two single cones. The TO type being cup povides goove with oil holes fo lubiction. These beings e vilble with o without cone spces. 107

2 Tpeed olle eings The TO type being with the cone spce is sold s mtched ssembly to povide peset clence fo chieving optimum being life. It sves instlltion time by eliminting the need to djust clence duing being instlltion in the system. The components fo the TO type being without cone spce cn be bought individully by the being use. In eithe cse, the NTN Appliction Engineeing eptment should be consulted to detemine the optimum clence needed fo the ppliction. These beings cn suppot thust lods in eithe diection nd hve dil lod cpbilities gete thn the single ow beings. ouble Two ow eings (TI Type) The TI type being consists of double cone hving one piece constuction with two cewys, nd two single cups. The being is vilble with o without cup spce. The TI type being with cup spce is sold s mtched ssembly to povide peset clence fo optimum being life. These beings cn suppot thust lods in eithe diection, nd hve dil lod cpbilities gete thn single ow beings. The TO type being is lso vilble in configution designted s TOC type. This type of being is simil in evey espect to the type TO being except it hs one of the lubiction holes counte-boed in the cup. y inseting pin in this hole the cup cn be locked in plce ginst cicumfeentil nd xil movement in the housing. The TOC type vesion is lso the sme s the TO type being except tht the TOC cup hs no goove in the O.. nd only one hole counte-boed fo pinning plus lubiction pssge. Non-Adjustble ouble Two ow eings (TNA Type) The TNA, TNAC, TNAC nd TNASE types fo simil to TO, TOC nd TOC types except the fome types hve the intenl clence contolled by flush-mounting the extended font fces of the cones ginst ech othe. Slots in the cone font fce of the TNASE type llow fo the flow of lubicnt. Fo most pplictions, the pe-set intenl clence is stisfctoy, povided the ecommended fitting pctices e used. ouble Fou ow eings (TQO Type) The TQO type being consists of two double cones, one double cup, two single cups, one cone spce nd two cup spces.the TQO type being hs lubiction holes povided in the cup spces, the cone spce, nd the double cup. The TQO type being is mtched ssembly to povide the equied end ply fo the ppliction. This being cn suppot thust lods in eithe diection nd hs thust nd dil lod cpbilities gete thn the TI type nd TO type beings. These beings e nomlly used s wok oll beings in steel mills. 108
