MD Series rock bit
High speed motor bit

Working condition of the rock bit in directional and horizontal drilling applications is quite different than in vertical well drilling .our factory’s new MD series motor bit features high RPM , Better gage protection and stability ,higher reliability,

Compared with the former axial roof fan, this series fan is a new product and it has the characteristics of high efficiency, low noise, corrosion resistance and high precise stabilization.
It has large amount of wind and lower pressure than centrifugal fan. So it is applied to such occasions with

GF-63 twin-tube extrusion lines

•Because of the perfect two-pipe vacuum sizing system.
•Independent control of the overall structure of the twin-tube traction and synchronous cutting device.
•With accurate and free

Description
Product group: Piston seal
Design: K compact seal
Profile no.: 22
Specification: Z suitable for two-sided pressure load
Seal material: NBR fabric NBR F 90 3005
Seal body: NBR 80 3001
Guide rings: PA

Operational application limits
Pressure (MPa): ≤ 40
