Turbine and journal bearing re-babbitting
A worn or wiped babbitt layer does not mean a new bearing. We strip, re-pour and machine the white-metal lining of your existing shells — turbines, generators, motors, pumps, fans and compressors — and return them inspected and ready to install, typically at 20–30% of the price of a new part.
What we repair
- Steam and gas turbine journal bearings
- Generator and electric motor bearings
- Pump, fan and compressor bearings
- Split shells and solid bushings
- Bearings with oil grooves, pockets and jacking-oil ports
- Bores from 100 to 3000 mm, parts up to 5 t
How we do it
- 01
Incoming inspection
We measure the shell, map defects and check the steel backing before any work starts.
- 02
Removal and tinning
The old babbitt is melted out, the base is cleaned and tinned to ensure a full metallurgical bond.
- 03
Casting
A new layer is cast from our own alloy — static or centrifugal, depending on size and geometry.
- 04
Machining
Bore, grooves and joint faces are machined to your drawing or to the original dimensions.
- 05
Inspection and report
UT bond test, dye penetrant inspection and alloy analysis; a dimensional report ships with the bearing.

Frequently asked questions
How long does re-babbitting take?
Typically 10–15 working days from receipt of the bearing, depending on size and quantity.
Which babbitt alloys do you use?
Tin-based and lead-based grades: B83 and B16 (GOST), ASTM B23 Grades 1, 2, 3, 7 and 8, and ISO 4381 alloys such as SnSb12Cu6Pb and SnSb8Cu4. If your OEM specifies a grade, we match it.
How do you confirm the bond quality?
Every bearing is checked by ultrasonic bond testing and dye penetrant inspection, and the alloy composition is verified. You receive a report with the part.
What should I send for a quote?
