2 Description Te Frontseal is an all elastomer axial seal for rotary safts an bearings. It rotates wit te saft an seals axially against a stationary counterface perpenicular to te saft. Tis type of seal as been use wiely for several applications an as prove to be reliable an effective against ust, irt, water an oil splas an oter meia. Te ring consists of tree parts: c a a) Te seal boy, installe wit interference to te saft. b) Te inge, acting as a sprung connection between te boy an te lip. c) Te conical an flexible sealing lip wic provies te actual ynamic sealing against te counterface. Te counterface can be te sie wall of te bearing, a waser or any ousing. Stanar seal types b Te Frontseal is manufacture in four stanar profiles: It s te most common profile. It as a perpenicular rear face. Wie range of sizes, from to over 00 mm safts. Wie boy to ensure iger raial force tan type. Range of sizes from 5 to mm safts. Tis seal is intene for applications were available space is narrow. Range of sizes from 0 to over 0 mm safts. X Tis seal is more compact tan type, commonly use in confine spaces. Size list available on request. VRME It s a eavyuty large iameter seal, use for instance in steel milis, paper milis an rolling milis as a irt/water excluer seal. A clamping ban can be use to improve axial fixation. Range of sizes from 00 to over 00 mm safts. Tis eavyuty profile is also esigne primarily for protecting ig spee bearing arrangements in rolling mills, papermaking an large macine applications. A clamping ban can be use to improve axial fixation. Size list available on request. 2 X eavyuty Frontseal, esigne primarily for large ig spee bearing arrangements, use for instance in rolling mills an papermaking macine applications. Aitionally tey can be use as seconary seals for eavyuty applications were te primary seal as to be protecte against water an/or particular contamination. Range of sizes from 0 to over 00 mm safts. Oter types, moifications or larger iameters available upon request.

3 Installation an operation Fitting Fitting a Frontseal is very simple. Te ring must be sligtly stretce an puse along te saft. It can eiter be one manually or wit a simple tool, in a way tat te istance to te counterface can be maintaine constant over te circumference using little pressure. Te lip of te Frontseal soul be lubricate wit a tin film of grease or silicone oil. In case were friction must be reuce, coat te counterface wit a low friction agent an o not apply grease to te lip. Te saft soul be preferably ry an free from oil an grease. Frontseal not preloae Frontseal fitte wit preloaing using a tool Eccentricity / Misalignment Te Vsape of te Frontseal provies an effective an reliable sealing even wit oval section, saft runout, eccentricity or saft misalignment. Sealing is not even affecte by a sligtly tilte counterface (maximum permissible flatness eviation is usually efine as 0. mm per 00 mm). oval an/or eccentrically turning saft tilte counterface 2

4 Installation an operation ounterface Te type of counterface finis is very important for an efficient sealing an for useful life of te seal. Te surface must be smoot, free of scratces an sarp peaks. Te coice of surface finis epens on te meium to be seale an on te saft spee. Te coice of counterfaces material is igly epenant on te meium too. For normal operating conitions, conventional mil steel of min B is sufficient. Wit an increase in spee an te presence of abrasive particles, te arness of te counterface must also be increase. Surface treatment is suggeste for water splas or oter corrosive meia. Periperal spee Due to te influence of te centrifugal force, te contact pressure of te lip ecreases wit increase spee. At periperal spee up to m/s te lip of te Frontseal as a goo pressure against te counterface an it as te function of a ligt contact seal. Over m/s te seal must be axially supporte an above m/s raial retention is necessary, mounting te Frontseal in an axial groove or applying an aequate support. 2

5 lamping bans & clips for Frontseal Type in AISI0 Wen te Frontseal is fitte on te saft, te boy of te ring is subject to a centrifugal force an can move from te saft. For tis reason te Frontseal requires raial retention tat can be supporte by a clamping ban. Sort escription of tecnical features Te multirange clamping bans are ieal for use in many ifferent applications wit a ig mecanical loa. Wit its tensile strengt an te even tension force istribution it sets stanars for reliable clamping. Te clamping ban perfectly fits on te Frontseal an ensures an optimal tigtness. Te clamping ban as a wit of mm an a tickness of 0. mm, perfectly fitting into te grove of DITA Frontseal Type wic is mm on all iameters. Bot te clamping ban an its clip are elivere in stainless steel AISI 0 material. orrosion resistance in salt spray testing: min. 0. lamping bans for Frontseals type are also available 2

6 Prouction an Quality assurance Our Frontseal is manufacture accoring to Quality Assurance Stanars ISO 00. All prouction pases are cecke an all measurements are recore an store for tracing. Our Frontseal is iniviually inspecte to ensure tat sealing ege an sealing ban are free from faults. Also small cracks an sortcomings wic coul cause a split uring installation or operation of te seal are not accepte. sealing ege sealing ban Storage an anling Some storage precautions must be taken in orer to avoi eterioration of te material. Frontseal soul be store in a ust free an ry atmospere an tey must be kept in teir original packaging wic soul only be opene just before installation. Samples soul be repacke after inspection. Do not rop Frontseal on selves or boxes, nor ang seals on ooks, wires or nails, since in eiter case te seal can be amage. Seals soul be store on a firstin firstout basis to avoi ageing on te self. Avoi storage near sources of eat or near electrical equipment tat may generate ozone. Also keep away from irect sunligt. Avoi unnecessary pressure on te lip uring storage. 0
