We supply Single row tapered roller bearings, Double row tapered roller bearings, Four row taperedroller bearings.
Applications
Single row tapered roller bearings are typically used in applications with combined loads. Single row tapered roller bearings can also be used in sets. Single row tapered roller bearings can be matched face-to-face, back-to-back or in tandem to deliver specific advantages depending on operating conditions.
Double row tapered roller bearings are typically used in gearboxes, hoisting equipment, rolling mills and machines in the mining industry.
Four row tapered roller bearings are used almost exclusively in work roll applications such as rolling mills.
