2BS315A transmission output shaft flange (rear), 6-hole 252101240

Product Introduction

This 252101240 rear output shaft flange (also known as hand brake flange) is a critical connection component for the 2BS315A planetary transmission, widely installed on XCMG LW500K, ZL50G and ZL50 series wheel loaders. As the rear output assembly of the gearbox, it transfers torque from the transmission to the hand brake system, undertaking power transmission and parking braking connection functions.

The flange adopts high-quality alloy steel blank, processed through multi-step CNC turning, spline broaching and surface strengthening treatment. The inner spline and 6-hole mounting layout are precisely machined to match the original assembly requirements. The stepped boss structure improves torsional rigidity, effectively resisting torque shock and load vibration during loader operation. It ensures coaxiality during power transmission, reducing shaking, oil leakage and spline wear under heavy-duty construction, mining and earthmoving working conditions.

We strictly follow OEM dimensional specifications for production, fully interchangeable with original spare parts. Each finished flange undergoes spline inspection, flatness testing and dimensional verification before delivery. We supply OEM equivalent and premium aftermarket grades, with export packaging and complete customs documents for overseas construction machinery distributors and repair workshops.
