Product Introduction

The 2777/2720 is a specialized configuration within the standard 2700 inch-series of tapered roller bearings. Sized at 38.1 x 76.2 x 23.812 mm, this specific pairing utilizes the 2777 cone, expertly engineered to provide pinpoint shaft alignment and high rigidity under torque. Manufactured using premium high-carbon chromium steel, it delivers outstanding fatigue resistance and thermal stability. Global B2B mechanical rebuilders and industrial transmission manufacturers rely on the 2777/2720 for continuous, heavy-duty operational uptime.

Applications

Heavy-duty industrial speed reducers and pinions.
Automotive transmission main shafts.
Agricultural combine harvesters and tractor axles.

FAQ

Q: Can this bearing withstand heavy axial thrust forces?
A: Yes, its single-row tapered geometry is inherently designed to manage high unidirectional thrust loads alongside radial forces.
Q: Do you offer material test reports?
A: Yes, comprehensive Certificates of Analysis (COA) are available for all B2B wholesale orders.
