Special Oil Seals

Ank Seals provides complete solutions for sealing problems with their technology know-how and engineering proficiencies to meet specific requirements both quickly and professionally. The rotary shaft seal L2M has been developed specifically for the severe operating conditions encountered in the rolls of paper making machines and cold rolling mills. The life and performance of a lip seal are largely dependent upon the preload of the seal lip on the shaft. In this respect the L2M design offers a significant advantage over conventional garter spring seal types as a result of its highly elastic garter finger spring combination. Shaft misalignment (shaft deflection, bearing clearance, out of round and run out) creates changes to the lip preload that can in conventional seals compromise either or both lip tip sealing integrity and seal life. The finger garter spring combination in L2M largely eliminates the effects of external forces causing changes in lip tip preload and therefore is more likely to maintain the fluid film underneath the lip the condition of which has the greatest effect on seal life and performance. Even with the severe misalignment capability of the L2M design high speeds are also permissible up to 35 m/s. When fitting the L2M seal over a long shaft or into a housing where the lip cannot be seen another significant advantage is evident as the spring cannot come adrift from its housing as a result of the garter finger spring configuration eliminating spring detachment. All garter and finger springs are constructed from stainless steel. The finger spring being clamped and the sealing lip bonded to the metal of the case eliminating any potential leakage between the seal components.
