Conheça um pouco mais sobre as Vedações para Motores Diesel da Simrit |
Jun 1121 |
A linha Simrit para Motores Diesel engloba outros produtos de vedação e controle de vibração de alta tecnologia, como retentores para os injetores, anéis de camisa, juntas e coxins hidráulicos. Conheça um pouco mais sobre o Retentor do Virabrequim e o Selo com Lábio para a Vedação de Gases:
Retentores especiais para o virabrequim
Com o avanço da injeção eletrônica diesel, a novidade que a Simrit apresenta para a vedação traseira do virabrequim é o Retentor com Sensor Magnético. Produzido a partir de um polímero PTFE carregado com ferrita, garante um excelente potencial de vedação, baixo atrito com o eixo e um sinal de alta precisão em todas as faixas de rotação.
Para a parte dianteira, foi desenvolvido o exclusivo Retentor Casco. Seu lábio em formato de dupla hélice cria uma ação centrífuga de bombeamento do óleo lubrificante. Dessa forma, une um baixo atrito e alto poder de vedação. Sua construção robusta, tipo cassete, evita danos durante o manuseio e instalação.
Emissões sob controle
Para ganhar eficiência, os novos motores diesel também trabalham com pressões cada vez maiores nas câmaras de combustão e coletores. A vedação das válvulas se tornou um desafio. É preciso, além de garantir a lubrificação das hastes, evitar fugas de gases e óleo.
A solução Simrit é o Selo com Lábio para a Vedação de Gases. Ao proteger o retentor das altas pressões do sistema, o lábio garante a correta lubrificação das hastes das válvulas, reduz a queima de óleo e, conseqüentemente, as emissões de poluentes.

Simrit Launches Energy-saving MileMaker™ Seal |
Mar 1026 |
PLYMOUTH, Mich., March 22, 2010 – Offering friction-reducing and fuel-saving benefits for commercial truck and trailer customers, Simrit’s MileMaker™ seals are being globally introduced for both OE (original equipment) and aftermarket heavy duty truck and trailer wheel and axle applications. Designed and developed by Simrit – a division of global sealing specialist Freudenberg-NOK – the MileMaker seals operate with over 50 percent less torque than competitors’ seals, which can result in more than $1,000 in diesel fuel savings per commercial truck trailer combination over the life of the seal.
“Building on our many years of proven seal performance in the heavy duty industry, the new MileMaker sealing solution delivers significant energy savings and raises the performance bar for wheel seals in the heavy duty truck and trailer industry,” said Tim Guzman, sales director for heavy duty truck, Simrit. “In brief, the MileMaker sealing solution is a win-win solution for Simrit’s customers and the environment.”
Working to anticipate customer demands, Simrit designed the MileMaker sealing solution to address key issues facing the heavy duty industry, such as higher wheel end temperatures, longer service life requirements and increased durability.
Developed using a proprietary elastomer material to withstand higher operating temperatures (up to 350 F), the MileMaker seal is compatible with mineral and synthetic oils, and grease lubricants. The integrated lathed, ground and polished wear sleeve running surface reduces friction, lowers torque and promotes cooler running for the main seal lip. The advanced main lip design geometry results in low-friction performance while not sacrificing dirt exclusion capabilities.
The MileMaker seal also incorporates special dirt exclusion fins that assist with keeping contamination away from the seal. The lubed rubber OD (outer diameter) and ID (inner diameter) design eases installation force, which results in less heat generation and increased seal life, and seals any minor hubs or spindle imperfections. The seal design has low internal torque aided by an internal lubricant, which translates to lower internal heat generation, excellent wear resistance and improved fuel economy.
The Simrit Division is based at Freudenberg-NOK’s headquarters in Plymouth, Mich., and is part of the Freudenberg and NOK Group, which has total annual sales of more than $12 billion. Simrit offers an extensive portfolio of sealing solutions for the aerospace, appliance, energy, heavy duty truck, industrial, marine, mobile machinery, recreational vehicle and semiconductor markets.

"Engineered Seals Withstand Extreme Conditions," as featured in Machine Design |
Feb 1019 |
Click here to view the article on Simrit’s sealing solutions for extreme conditions that Machine Design recently featured on their website and in their printed magazine.
Quote taken from the article:
Key points:
• Aerospace applications may call for seals that are fireproof, resist fluids, and work over a large temperature range.
• Viscoelastic properties help elastomeric seals work in subfreezing temperatures.
• Semiconductor and alternative energy applications require low-maintenance seals that resist chemicals and weather.
Simrit’s New High Pressure Radial Shaft Seals Brochure |
Dec 0917 |
The updated brochure features the premium pressure seals from Simrit that offer one-piece construction, small load rise as a function of pressure, and improved seal life span due to improved lubrication at the sealing lip.
The radial shaft seals are designed to prevent deformation via a combination of a shorter flex section, flex section support features, reinforced metal cases, defined lip geometries, and proprietary wear resistant materials.
The brochure includes designs for medium pressure seals of TCV, TCN, PPS, and PTS radial shaft seals, and high pressure seals BAHD, HPS, and HPLS (patented) radial shaft seals. The HPS seal and the HPLS seal work in challenging applications, including pressures up to 175 and 200 bar, respectively.
