6. Frequently Asked Questions

Q: What is the difference between double row tapered roller bearing and single row tapered roller bearing?

A: Single row tapered roller bearing can take radial load plus one-way axial load, while double row tapered roller bearing can withstand radial load plus bidirectional axial load and resist overturning torque. Double row type has higher rigidity, so it is widely used in heavy gearbox and truck axle where shaft deflection and overturn force exist. Many buyers search double row tapered roller bearing vs single row tapered roller bearing for equipment selection.

Q: When should I choose DB DF DT arrangement for double row tapered roller bearing?

A: DB back-to-back has the largest moment rigidity, suitable for equipment with overturn torque like crusher main shaft. DF face-to-face allows more shaft misalignment, commonly used in general heavy reducer. DT tandem is adopted when large one-way thrust load exists, such as conveyor driving drum. You can specify DB DF DT when you inquire double row tapered roller bearing.

Q: What is W33 and C3 meaning on double row tapered roller bearing?

A: W33 means outer ring with oil groove and 3 lubrication holes for circulating oil lubrication, widely used in continuous running heavy machinery. C3 is larger internal clearance than standard group, used for high temperature working condition where thermal expansion happens. C4 clearance is bigger than C3 for severe impact and high temperature heavy load.

Q: Can your double row tapered roller bearing replace TIMKEN or SKF original bearings?

A: Yes. Our 35000 37000 38000 39000 series double row tapered roller bearings are manufactured strictly according to ISO metric standard, mounting dimension, tolerance and load rating match mainstream brands. It can directly substitute TIMKEN and SKF equivalent double row tapered roller bearing without changing housing or shaft size.

Q: Do you have stock for 352024, 372026, 382022 double row tapered roller bearing?

A: We keep large inventory for mainstream models including 352024,352026,372022,372026,382022,392024 and related suffix versions like DB DF W33 C3. Standard stock items can be shipped within 3-7 working days. Custom clearance and special configuration will have longer lead time.

Q: Can you make OEM laser marking and neutral packing for double row tapered roller bearing?

A: Yes, we support custom laser logo, neutral export packing and customized clearance grade for global importers and distributors. Long-term bulk buyers of double row tapered roller bearing can get competitive factory price and stable supply schedule.
