Standard-type Power End Crosshead

The crosshead is a critical motion-conversion component in the power end of a plunger pump. It efficiently transmits the rotary force from the crankshaft-connecting rod system and converts it into precise linear reciprocating motion to drive the plunger. Its stability directly affects sealing life and energy output efficiency. Our crossheads are integrally forged from alloy steel, offering exceptional durability. A double-wedge oil groove lubrication structure ensures the continuous formation of a high-pressure oil film, minimizing wear under extreme loads. The guide sleeve is embedded with self-lubricating bearings, working in tandem with precision-ground columns to eliminate lateral loading. This design is ideal for heavy-duty applications such as oilfield fracturing and ultra-high-pressure pumping.
