Functions and applications of Excavator Bulldozer Hydraulic Cylinders:

With the advancement of processing technology, Qingdao Micro Precision Machinery Co., Ltd. has achieved a number of technological breakthroughs in this field after years of technological innovation and performance optimization. The company already has the ability to produce hydraulic cylinders on a large scale. All hydraulic cylinders shipped from the factory have been tested on high-pressure test benches and are accompanied by test reports. With reliable quality assurance, the hydraulic cylinders it produces are suitable for Komatsu excavators, Hitachi excavators, Carter excavators, Kobelco excavators, and Doosan Daewoo excavators. Modern excavator. Sumitomo excavators. Kato excavator, Case excavator, Volvo excavator. Liugong excavators, Sany excavators and other series.

Product advantages:

Compact structural design, use of high-strength materials and special heat treatment and welding processes ensure that the bulldozer cylinder has extremely high fatigue durability life under high pressure and heavy load.

Provides a variety of surface anti-corrosion treatment solutions: Ni/Cr electroplating/ceramic spraying, laser cladding, QPQ, etc.

Hydraulic locks, explosion-proof valves, oil pipes, etc. can be designed and integrated as required.

The design temperature range is (-25℃～+120℃), and we can provide higher or lower cylinder customization services.

The mature buffer design reduces the impact of the bucket cylinder during excavation operations without reducing the excavation force and affecting work efficiency.

The earrings of integral die forgings can be equipped with standard self-lubricating bushings, or they can be configured according to customer needs.
