SKF launches taconite seal for wet and contaminated applications 08 April 2015

Bearings giant SKF has unveiled a taconite seal design aimed at split block bearing housings requiring protection in extremely contaminated and/or wet environments.

SKF global industry manager for mining, mineral processing and cement, Keith Meyers, says the new seal is suitable for the most demanding of applications, and adds that it is also price competitive.

"SKF's new taconite seal provides optimum protection, easy assembly and alignment, and simple specification," states Meyers.

"In the extreme of harsh and contaminated environments, reliability can be further improved by combining the new seal with an upgraded SKF Explorer spherical roller bearing and a grease barrier in an SKF housing," he advises.

And he adds that this greater level of protection from dust, grit and moisture helps achieve maximum bearing service life, while optimising machine performance and uptime.

This latest seal comprises a compact, multi-stage labyrinth cartridge seal, with an internal low friction V-ring that forms an additional barrier to contamination and provides an effective grease purge.

The rotating labyrinth ring faces the bearing housing to deflect and fling water away.

It has been designed for use in industries such as mining, mineral processing and pulp and paper, where ingress of contamination causes premature failures of bearings.

The new seal is available for almost all SKF metric and inch split block housings starting from 50mm (1-15/16 inch) shaft diameter.
