Trelle­borg un­veils new ro­tary shaft seal for mo­tor­sport ap­pli­ca­tions

Trelle­borg Seal­ing So­lu­tions has launched an in­no­va­tive ro­tary shaft seal which pro­vides “su­pe­rior ex­e­cu­tion” and will “out-per­form” other prod­ucts in the mar­ket. The Tur­con Var­ilip PDR ro­tary shaft seal has fast be­come the cho­sen prod­uct by sev­eral high pro­file mo­tor­sport clients who know it will max­i­mize re­sults and keep their teams win­ning.

Care­fully de­vel­oped to ex­tend the bound­aries im­posed by elas­tomer ra­dial shaft seals, the Tur­con Var­ilip PDR ro­tary shaft seal utilises ad­vanced ma­te­ri­als and de­sign tech­niques to pro­vide op­ti­mum seal­ing per­for­mance for mo­tor­sport ap­pli­ca­tions. It is char­ac­terised by low fric­tion stick-slip-free run­ning, re­duc­ing tem­per­a­ture gen­er­a­tion and per­mit­ting higher pe­riph­eral speeds.

An­drew Long­don, UK Tech­ni­cal Man­ager at Trelle­borg Seal­ing So­lu­tions said, “We have be­come the lead­ing pro­duc­ers of light­weight, fric­tion-re­duc­ing ro­tary shaft seals which are suc­cess­fully used on For­mula One and IndyCar rac­ing plat­forms. Ro­tary seal torque and power con­sump­tion varies greatly with seal de­signs and ma­te­rial, which is why it has be­come so im­por­tant to iden­tify seal con­fig­u­ra­tions that achieve the best pos­si­ble per­for­mance for rac­ing re­quire­ments.”

“The de­sign of the Tur­con Var­ilip PDR ro­tary shaft pro­vides a su­pe­rior seal­ing so­lu­tion which re­tains a com­pact seal en­ve­lope. It is ac­cepted that stan­dard elas­tomeric ro­tary shaft seals have a lim­ited ap­pli­ca­tion range, which is why we know that our ro­tary shaft seal will out-per­form other prod­ucts in the mar­ket ev­ery time.”

What makes the seal truly unique is the fact it is con­structed from only two parts – a pre­ci­sion man­u­fac­tured metal body and a me­chan­i­cally re­tained Tur­con seal­ing el­e­ment. Un­like seals with pressed metal cases, a gas­ket is not re­quired to pro­vide seal­ing be­tween the lip and cas­ing. This is pro­vided by the me­chan­i­cal re­ten­tion of the lip, im­prov­ing both the chem­i­cal re­sis­tance and tem­per­a­ture range of the seal­ing sys­tem.

The op­tion of an in­te­grated end plate for Tur­con Var­ilip PDR ro­tary shaft seal can also al­low end users to op­ti­mize their hard­ware de­sign to min­i­mize en­ve­lope and part count.

In ad­di­tion, the Tur­con Var­ilip PDR ro­tary shaft seal is avail­able with a hy­dro­dy­namic feature on the Tur­con seal­ing lip which pro­vides a pos­i­tive dis­place­ment of fluid as a re­sult of the shaft ro­ta­tion to give im­proved seal­ing in ap­pli­ca­tions where the shaft only ro­tates in a sin­gle di­rec­tion. The feature also in­creases the flex­i­bil­ity of the lip, al­low­ing a wider con­tact area be­tween the Tur­con lip and the shaft, help­ing to re­duce shaft load and as­so­ci­ated wear and tem­per­a­ture gen­er­a­tion.

As well, like all Tur­con Var­ilip PDR seals, the ro­tary shaft seal is ca­pa­ble of out­stand­ing the high and low tem­per­a­ture per­for­mance com­pared to elas­tomeric ma­te­ri­als.

Un­like other PTFE lip seals, Trelle­borg’s Tur­con Var­ilip PDR seal is not lim­ited in its tem­per­a­ture per­for­mance by the pres­ence of an elas­tomer gas­ket. This gives it ex­cel­lent tem­per­a­ture range ca­pa­bil­ity. It also has an ex­cep­tional re­sis­tance to oil ad­di­tives and bio­fu­els, which can have an ad­verse ef­fect on many elas­tomers. Us­ing Tur­con shaft seals al­lows the in­creased use of ad­di­tives and gives a longer oil ser­vice life.
