Product Description of NTN self-aligning roller bearing
Qingdao Flow Group Ltd. virtually every type of ball and roller bearings. They are available in various cross sections and satisfy a huge variety of operating conditions and application performance requirements.
A wide assortment of plain bearings, rod ends and bushings are also available to satisfy various oscillating movement needs. The design and material variants are extensive and offer an unparalleled selection from which to meet your application needs.

Bearing characteristics: NTN self-aligning roller bearing is a rolling-element bearing that permits rotation with low friction, and permits angular misalignment. Typically these bearings support a rotating shaft in the [bore] of the inner ring that may be misaligned in respect to the outer ring. The misalignment is possible due to the spherical internal shape of the outer ring and spherical rollers.

Application: NTN self-aligning roller bearings mainly used in electric heating ring, marking machine, liquid glue, eyedrops machinery, packaging equipment, compressor, electric heater, filter material, differential pressure transmitter, automotive lamps and other equipments.
