SKF launches new seal head unit for shock absorbers for off-road vehicles

SKF launches a new seals head unit, an integrated application for off-road vehicles, such as enduro and cross motorcycles, snowmobiles and quads. The new product increases vehicle performance and comfort for riders and makes maintenance easier for suspension specialists. The unit can operate in a wide temperature range (-40 °C to +150 °C), excluding contaminants and reducing friction and wear.

SKF shock absorber

The seal head unit consists of five pre-assembled components: An integrated monotube seal, a washer, a bushing, the seal head and a dirt scraper. The integrated monotube is itself an assembly of five pre-assembled components; an oil seal, a bumper, an O-ring and a back up ring to support the main lip under high pressure. Together with the unit, SKF offers the service kit to supply all necessary components for simplified and efficient maintenance of the SKF seal head unit. The service kit includes the integrated monotube seal, the bushing and the dirt scraper.

Because it is a single unit it can be mounted quickly, saving time compared to traditional multi-component solutions. The integration of the static seals into the monotube seal assures no air between those five integrated components, simplifying the process to purge air from the system.

The new seal head unit has been developed and tested, both in the SKF laboratory and on the field by leading OE shock absorber manufacturers.

The dirt scraper is a new design for the application that provides low friction and excellent dirt exclusion.

SKF was present at EICMA 2012, 13-18 November on the Innteck stand, SKF’s distribution partner for two wheelers’ sealing solutions, to present this new technological solution. This latest innovation adds to the other two seals solutions that the company launched to the market in the last three years, namely fork seals and a wheel seal kit.

This article, press release or announcement is translated from BearingNEWS (www.bearing-news.com) publications and adapted for the Chinese bearing industry professionals. << Replacing Roller Bearings with GGB Plain Bearings >> 当今GGB轴承技术提供的先进滑动轴承与滚动轴承相比具备很多优势。当今GGB轴承技术提供的先进滑动轴承与滚动轴承相比具备很多优势。 除了它们的简单设计和成本效益,滑动轴承提供更大的负载能力,更大空间,重量更轻,更紧凑的设计节省重量。此外他们补偿偏差,减少边缘载荷和抑制噪声和振动。因为它们不包含运动部件,轴承也提供更安静的工作环境,更可靠的性能,并且只需要很少维护。 这些优势是由设计工程师在广泛应用滑动轴承替换滚动轴承来实现的。这些应用包括风力涡轮机,农业设备,转向系统,空调压缩机,发动机摇臂,节流阀,变速箱和传动系统,和头目,其中。潜在应用包括海上浮式生产储油系统,制动机构,发电机和起动机。 滑动轴承也不是适合所有应用。尤其是在需要超低摩擦和/或高精度轴位置。但是在涉及高载缓慢的振荡运动中滑动轴承就显示出了优异性,因为滚动轴承的滚动部件脱落可能会导致过早失效。 用GGB轴承取代传统的滚动轴承可以给用户提供技术和竞争优势。更大的接触面积提供高承载能力和抗疲劳破坏,冲击和边缘载荷。轴承的摩擦特性也抵抗惯性和高速滑行,滚子轴承的主体,他们容忍偏差优于许多滚动元件设计。 紧凑的整体结构和较小的外壳,节省空间和重量。简单的压入配合几乎消除了安装的潜在损害。转换为滑动轴承还可以降低部分成本,低风险装配。 完整替换滚动轴承与普通轴承的文章,请点击 http://machinedesign.com/article/plain-bearings-outperform-rolling-element-bearings-0407 更多信息请联系 china@ggbearings.com
