Labyrinth Seal TS or TSNA 500S or 600S

Labyrinth Seal is used with SN, SNA, SNH, SNL, SD and SAF type housings. For large Plummer block housings, like SDJ, SDG SBD, THD types, the Labyrinth Seal is the preferred choice.

Selection of seal for Bearing Housings

Selection of seal for Bearing Housings should be done carefully since seal has very important role in functioning of bearing and bearing housing. An efficient seal adds to the life of a bearing by keeping dirt, dust, contamination and foreign particle outside the bearing housing whereas it prevents the lubricant from leaking out of bearing housing. To satisfy this basic requirement of a trouble-free bearing, a suitable Seal plays very important role. There are five main types of seals which are popularly selected for bearing housings. (1). FELT (2). V SEAL (3). DOUBLE LIP SEAL (4). LABYRINTH and (5). TACONITE. All will be under “MECO” make.
