SKF launches a new taconite seal design for extremely wet and contaminated environments
2015 April 24, 09:00 GMT
Suitable for the most demanding of applications, SKF’s new taconite seal is price competitive and delivers an increased level of protection to bearings in split block housings that operate in extremely contaminated and wet environments. This greater level of protection from dust, grit and moisture contamination helps achieve maximum bearing service life while optimising machine performance and uptime.
This latest taconite seal from SKF is 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 specifically designed for use in industries such as mining, mineral processing and pulp and paper, where ingress of contamination causes premature failures of bearings, causing expensive unplanned machine shutdown.
The new taconite seal design is available for almost all SKF metric and inch split block housings starting from 50 mm (1-15/16 inch) shaft diameter. The seals are available in both metric and inch shaft diameters and fit, without modification, into the seal groove of SKF split block housings. As an alternate option, larger taconite seals (≥ 340 mm shaft diameter) are also available for ‘bolt-on’ mounting to specially prepared SKF split block housings. All the seals feature a circumferential groove on the outer surface that simplifies and speeds up the alignment and assembly process.
“SKF’s new taconite seal provides optimum protection, easy assembly and alignment and simple specification,” said Keith Meyers, Global Industry Manager – Mining, Mineral Processing & Cement, SKF. “In the extreme of harsh and contaminated environments, reliability can be further improved by combining the new taconite seal with an Upgraded sealed SKF Explorer spherical roller bearing and a grease barrier between them, in an SKF housing for the ultimate SKF three-barrier solution."
