Loader through shaft

Product Introduction

The through-shaft is a core power transmission shaft component in a loader’s gearbox. It runs through the gearbox housing, connecting the input, output, and intermediate transmission components. Its main responsibility is to transmit engine power, driving the synchronous operation of gears, planetary carriers, and other components. It is a key shaft component ensuring continuous power transmission and smooth gear shifting.

Made of 40Cr high-strength alloy structural steel, forged in one piece, and subjected to heat treatment, precision turning, and fine grinding, the shaft boasts high rigidity, excellent tensile and torsional resistance, and is not easily twisted, broken, or deformed. Its smooth, burr-free surface ensures high precision, accurately matching bearings, gears, and oil seals. It is wear-resistant, resistant to high oil temperatures, and resistant to gearbox oil corrosion. Its dimensions strictly conform to original equipment manufacturer (OEM) standards, ensuring high interchangeability. No modification is required; it can directly replace the original loader’s through-shaft and is suitable for repairing and installing in various loader gearboxes.

Application Scenarios

• Construction sites: Earthmoving, site leveling, road construction, and frequent gear shifting and high/low speed switching operations require the through-shaft to provide stable power transmission with no loss, ensuring smooth operation of the entire machine.
• Quarry/Mining: Suitable for heavy-duty uphill and bumpy road conditions, bearing continuous high torque and strong impact loads. The shaft has strong torsional and compressive resistance, is not easily deformed or broken, and can withstand long-term heavy loads.
• Sand and Gravel Yards, Coal Yards, and Mixing Plants: Suitable for long-term continuous high-frequency operation, high load, and high speed operation. The through-shaft has slow temperature rise and minimal attenuation, ensuring smooth bearing operation and a low failure rate.
• Complete Machine Matching and Maintenance: Compatible with the repair and replacement of gearboxes for 3-ton, 5-ton, 6-ton, and 7-ton wheel loaders, and for new machine installation. Compatible with mainstream gearbox structures.
• Harsh Working Environments: Adaptable to dusty, high-oil-temperature, and high-frequency vibration conditions. Oil-resistant, corrosion-resistant, and anti-aging, the shaft surface is not easily worn, extending service life and reducing maintenance frequency.
