Except that portion of the outer ring of the same model dimensions

Single row tapered roller bearings have an outer ring, the inner ring and a set of tapered roller by a basket-type cage into an inner component. Outer and inner component separation, tapered roller bearings according to ISO standard dimensions, any standard model of a tapered roller bearing outer or inner component and the outer or inner components of the same model to achieve international interchangeable. Except that portion of the outer ring of the same model dimensions, tolerances must comply with ISO492 (GB307) requirements, the cone angle of the inner components, component cone diameter must also comply with the relevant provisions of the swap. [1]
Typically, single row tapered roller bearing outer ring raceway of the cone angle of 10 ° ~ 19 ° before, can withstand axial and radial loads combined effects. Cone angle larger axial load capacity are greater. Large cone angle of the bearing, post code plus B, cone angle between 25 ° ~ 29 °, which can withstand greater axial load. In addition, single row tapered roller bearings can be adjusted during installation size of the clearance.
Double row tapered roller clutch bearing outer (or inner) as a whole. Two inner (or outer) face close to the middle spacers, clearance by the thickness of the spacer to adjust, and can also be used to adjust the thickness of spacer double row tapered roller bearings are preloaded.
Four tapered roller bearings, such bearings performance and double row tapered roller bearing is basically the same, but more than double row tapered roller bearings withstand higher radial loads, lower speed limits, mainly for heavy machinery, such as rolling machines. [2]
Multi-sealed double, four-row tapered roller bearings, ZWZ provide long-life, multi-sealed double, four-row tapered roller bearings. Personalize bearing new design, changing the traditional design methods fully sealed bearings, sealed with a combination of new dust seal structure type, to improve the sealing effect and improve the sealing performance. Multi-sealed double, four-row tapered roller bearings with open structure bearing, life expectancy increased by 20% to 40%; lubricant consumption by 80%. [3]
