Hard-alloy radial bearings

The hard alloy radial bearings for PDM's and turbodrills are produced in a wide range of sizes as per customers' drawings:

Parameter Bearing diameter Bearing length
Inner
diameter
44 mm-228 mm 51 mm-242 mm
Outer
diameter
51 mm-42 mm 25 mm-460 mm


The operating conditions of the radial bearing run are agreed beforehand:
speed of rotation of the motor shaft , pressure drop across the bit, mud type ( drilling fluid), well configuration (deviation parameters), places of the bearing location in the motor bearing section ( at top, bottom).

Materials, used while production of the composite hard alloy bearing are resistant to the temperature of up to 650°C and are compatible with all the chemical reagents such as water, oil, gas, salt, H2S, H2SO3, H2SO4, HCl, Cl2.2.
