The power end mainly consists of the Pinion Shaft Assembly, Crankshaft Assembly, and Crosshead Assembly. Pinion Shaft Assembly includes Pinion Shaft, Pinion Shaft Bearing, Bearing Sleeve, End Cover, Seal Washer and so on.
Pinion Shaft is a key part of the power end, its ends protrude to the outside of the rack, used to install large pulley to input power to the mud pump.
The blank of pinion shaft is 40CrNiMo alloy steel forging with premium quality, through the rough, heat treatment, fashioning, hobbing.

DescriptionÂ
Phenolic Hydraulic seal is to guide the piston and piston rod of a hydraulic cylinder, as well as to withstand arising side loads. At the same time, it prevents any metal-to-metal contact, which will damage and score the surfaces and eventually cause seal damage, leakage and component damage. It is used extensively in mining applications. Â
