Four-row tapered roller bearings, TQO design

Contact Now

Depending on their design, four-row tapered roller bearings provide the following main features and benefits: Long service life The four-cup design (four separate outer rings) provides optimal load distribution over all four rows of rollers. Enhanced operational reliability.Design Attributes: Two tapered-bore single cones, one tapered-bore double cone, four single cups and three cup spacers. Front faces of single cones and both faces of double cone are extended to contact each other. Tapered cone bores are matched for continuous taper through the cones.

 

For metric-design medium-angle and steep-angle tapered roller bearings, the respective contact angle symbol C or D is added after the bore number. For normal-angle tapered roller bearings, no contact angle symbol is used. Medium-angle tapered roller bearings are primarily used for the pinion shafts of differential gears of automobiles.
