Single Row TSL Series390A Bearing

  • VAFEM Single row tapered roller bearing TSL series is a single-row bearing with a DUO-FACE PLUS seal pressed on to the large rib of the inner ring.

  • One lip of the DUO-FACE PLUS seal operates in the housing bore, the other lip seals against the hardened and ground surface of the outer-ring front face.

  • This bearing provides an effective means to integrate a seal into grease-lubricated applications operating at moderate speeds.

  • Consult your Timken engineer before making a final bearing selection to help ensure suitability, availability and the most cost-effective application.
