Mud Motor Ball

Product Detail

S-2 steel ball for

S-2 steel ball for Mud motor

A mud motor (or drilling motor) is a progressive cavity positive displacement pump (PCPD) placed in the drill string to provide additional power to the bit while drilling. Yusion supplies S-2 Rock Bit balls for mud motors. AISI S-2 Rockbit Ball is actually an shock resistant tool steel ball which owes its high tensile and yield strength, high hardness and wear resistance, high fatigue strength and impact toughness after heat treatment.The balls we produced are ranging from 6.35mm to 63.5mm with grade from G40 to G200.They provide the toughness and strength necessary for severe shock loads.

QUALITY CONTROL
We have been equipped with the world's most advanced steel ball surface quality inspection equipments-AVKIO eddy current test machine from Czech Republic & photoelectric appearance instruments and etc. to ensure our balls 100% final inspection.

 

 ISO 9001 & SGS CERTIFICATES

 

PACKING

Firstly we pack the balls in cartons.

1.For each carton,the size is : Length:160mm  Width:130mm Height:65mm

2.we pack our balls using wooden pallet(Plywood) in our export business

3.Put the plastic paper in the pallet(waterproof) at first, then put the ball carton into the pallet ,and fix the pallet.

4.The size of wooden pallet: Length:840mm  Width:780mm  Height:750mm

Generally, if you don’t want packing with our company’s logo & name and our package, we offer neutral packing and can according to your requirements.
