Four rowtapered roller bearings (Metric)

Four row tapered roller bearings (Metric)

 Internal bearing clearance after an investigation in advance, easy to use. Such bearing performance and double row tapered roller bearing is basically the same, but more than double row tapered roller bearings to withstand greater radial load, lower speed limits, mainly for heavy machinery. This kind of bearing can bear radial load and axial load in one direction secretly. The set of bearings can not be used alone, in the radial load, will produce additional axial force is often required to withstand an applied axial forces in the opposite direction to the bearing to be balanced, i.e., two sets of bearings in pairs. High speed clearance in the installation and use, can also be achieved pretension.
