Core Function
Crosshead Guideis the key load and guide parts in crank connecting rod structure of Reciprocating Compressor,located between connecting rod and piston rod. Through Crosshead pin,it could stably transfer the reciprocating inertial forces of connecting rod and gas load to the sliding guide rail while isolating lateral forces and transfer it into compressor body guide system,so that significantly reduce eccentric loading on piston rod and stuffing box,improving whole compressor operating stability、sealing life and reliability.
Operating Conditions
Crossheadoperates continuously under conditions of high load、high frequency reciprocating、fluctuating boundary lubrication,and it requires high standard in material strength、durability、surface quality and assembly precision.

Solution for Light-Duty & General Applications
Our forged Crosshead products adopt QT600-3/QT700-2 high-strength nodular cast iron in light-load general operating condition. After tempering,the tensile strength can reach out ≥700MPa,ballistic work Akv≥35J,balancing strength and impact resistance,possessing outstanding cost-effectiveness.
Solution for Medium/Heavy-Duty & Oil-Free Lubrication
When Crosshead Assembly was used in medium and heavy load conditions:selecting copper alloys,such as ZCuSn10P1 tin bronze、ZCuAl10Fe3 aluminium bronze etc.Refining grain size through centrifugal casting,improving material density(Porosity ≤ 0.5%),featuring inherent friction-reducing properties,being suitable for oil-free lubrication applications.
Solution for High-Pressure & Highly Corrosive Environments
When Crosshead Block was used in Super high pressure and highly corrosive conditions: using 304/316L stainless steel or duplex steel,after surface nitriding treatment,corrosion resistance has been enhanced by more than 3 times, making it suitable for harsh environments such as those containing oil, gas, and chemicals etc.
Core Selling Points & Customer Value
Steel crosshead assembly of our company surrounds three sell points:“Customized technical solutions、Long life low maintenance and being suitable for all scenes”,facing technical teams and procurement decision-makers at Compressor manufacturers、Oil and Gas chemical enterprises、heavy industrial manufacturers, and refrigeration and air conditioning companies.That solves high-standard precision assembly、poor adaptability、high return rates、harsh working conditions(high pressure/corrosion) and high maintenance costs etc.Conduct fatigue strength simulation testing,designing life ≥30000hrs(Exceeding the industry average by 50%),making it suitable for continuous operation.
