Product Description
Single row tapered roller bearingA single row tapered roller bearing has an outer ring, whose inner ring and a set of tapered rollers are enclosed by a basket shaped cage as an inner ring component. The outer ring can be separated from the inner ring component. According to the ISO tapered roller bearing outline dimension standard, any standard model of tapered roller bearing outer ring or inner ring component should be able to achieve international interchangeability with the same model of outer ring or inner ring component.
Usually, the cone angle of the outer race of a single row tapered roller bearing is between 10 ° and 19 °, and it can withstand both axial and radial loads simultaneously. The larger the cone angle, the greater the ability to withstand axial loads. A bearing with a large cone angle, with a trailing code B and a cone angle between 25 ° and 29 °, can withstand large axial loads. In addition, the clearance of single row tapered roller bearings can be adjusted during installation.Double row tapered roller bearingThe outer ring (or inner ring) of a double row tapered roller bearing is a whole. The small end faces of the two inner rings (or outer rings) are similar, with a spacer ring in the middle. The clearance is adjusted by the thickness of the spacer ring, or the pre interference of the double row tapered roller bearing can be adjusted by the thickness of the spacer ring. Four row tapered roller bearings have the same performance as double row tapered roller bearings, but they bear a greater radial load and a slightly lower limit speed than double row tapered roller bearings. They are mainly used in heavy-duty machinery.Four row tapered roller bearingsMulti sealed double and four row tapered roller bearings, ZWZ provides long life, multi sealed double and four row tapered roller bearings. Personalized and brand new design of bearings, changing the traditional design method of fully sealed bearings, adopting a new sealing structure that combines sealing and dust prevention, improving sealing effectiveness and sealing performance. Compared with open structure bearings, multi sealed double and four row tapered roller bearings have a 20% to 40% longer lifespan; Reduce lubricant consumption by 80%.Company Profile
