Four Row Tapered Roller Bearings

These tapered roller bearing variants are similar in form and feature to other tapered bearings. The distinct features are:

• Four cup design to enhance multi-direction weight management
• Self lubricating bearing with optimised raceway support
• Optimal seal design to prevent overheating and friction
• Each of these cups have their own strength, so sealed or not, each roller is capable of lasting for longer time

In case of a four row tapered bearing, there are two variants:

TQO (Straight bore four row bearing arrangement)

• Two double cones with cone spacer, two single cups
• Two single cups on either side with a double cup in the middle
• Two cup spacers separating single cup & double cup
• Spacers have holes for lubrication
• Cone spacers are hardened to reduce face wear

TQIT (Tapered bore four row bearing arrangement)

• One double cone with 2 single cone tapered bores matched through all the cones and four single cups with three cup spacers
• Lubrication holes in 3 cup spacers
• Faces of single cones and both faces of double cone contact each other

These variants are also provided with a helical groove inside bore and slots on the face of bearings for better lubrication. The preset assemblies ensure that
