With the introduction of the latest design of onsite compressor crankshaft grinding machines up to 700 mm, we can undertake the repair of compressor crankshafts that get seriously damaged due to the failure of bearings, accidents, or any other reasons. The job of compressor crankshaft repair which other companies from Europe cannot undertake, we execute it successfully only because of our experience of over four decades in this field. This makes us leaders in this field.

Repair of seriously damaged compressor crankshaft was successfully repaired by RA Power Solutions technicians

We were approached by a company having various oil rigs in Saudi Arabia for repair of their compressor crankshaft of reputed make of compressor having a standard crank pin diameter of 290 mm and main journal diameter of 320 mm.

Our team of senior technicians boarded the oil rig and the following action was taken for successful repair of the compressor crankshaft which was otherwise rejected by the compressor manufacturer and compressor crankshaft repair company.

• Due to the breakdown of the compressor, 60% of the operation comes to a standstill incurring heavy losses on per per-day basis.
• The crank pin of the compressor crankshaft having a 290 mm diameter was badly damaged due to the failure of the bearing. The bearing material was badly stuck on the crank pin.
• The damaged crank pin bearing was removed from the crank pin with great difficulty and the crank pin diameter was polished to undertake the inspection.
• The multiple cracks on the crank pin diameter were observed, there was higher hardness than specified, and taper and ovality of around 0.90 mm were also observed due to the failure of the bearing.
• In fact, due to the presence of multiple cracks lengths ranging from 12 mm to 119 mm, the reputed world-renowned compressor manufacturer rejected the crankshaft and advised to replace it with a new one offering delivery of 8 months from the date of placement of the order and on exorbitant price.
• After the planning of the repair strategy, the grinding of the crank pin was started.
• The number and intensity of cracks started vanishing during the process of grinding. The last under size crank pin permissible by the compressor manufacturer was 4 mm but RA Power Solutions technicians based on their experience and expertise decided to reduce the diameter of the crank pin by 6 mm and it was maintained as 284 mm against the standard crank pin diameter of 290 mm to save the compressor crankshaft from rejection and to resume the production.
• Despite undersizing the diameter by 6mm, 3 cracks measuring 10-25 mm were still present on the crank pin. The cracks on the crank pin are not acceptable as per the class and international standards.
• It was decided to remove the crack in the scooping technology.
• The cracks were fully removed by the Scooping Process and sharp edges were polished.
• The white metal Babbitt bearing was sent to our works for Rebabbitting and was sent back to the site after repairs.
• The compressor was assembled and for the last 18 months, it has been running continuously and giving satisfactory performance.

• Reciprocating Compressor

The above compressors are in operation all over the world for a wide range of applications in industries, oil and gas sector, textiles, chemical companies, etc.

We extend services related to the Polishing and Grinding of Compressor Crankshaft maintaining the following major parameters and tolerances.

• On site compressor crankshafts are repaired by RA Power Solutions of diameter ranging from 30 mm to 700 mm.
• No requirement of removing the crankshaft from the compressor casing or body.
• The grinding of the compressor crankshaft and repair are undertaken without the disassembly of the main equipment.
• The use of modern, state of art compressor crankshaft grinding machines can deliver tolerances in terms of taper and ovality within 0.02 mm with a surface finish of 0.20 Ra value or even less depending on the compressor manufacturer’s requirement.
• Any length of compressor crankshafts can be repaired on-site.
• Stop sending the crankshaft of the compressor to the workshop for repairs which requires tremendous efforts to remove of compressor shaft from the main body, pack it, and send it to the workshop.
• Accidental repairs are undertaken on priority by senior engineers and technicians employed by us on a 24/7 basis.

Compressor shaft requires service with passion

Availability of Compressor White Metal Babbitt Bearing and Tri Metal Bearing

Knowing the difficulty faced by our clients, we undertake regularly the Rebabbitting of metal bearings used in high-capacity compressors. We also manufacture new white metal Babbitt bearings for compressors as per the drawing or sample.

The Rebabbitting of old damaged bearings and manufacturing of new bearings is done with a great speed to reduce downtime. We also supply tri metal bearings used these days on compressor crankshafts with high RPM.

The undersize, special size, crank pin, and main journal bearings for most of the popular compressor models are available in stock or they are sourced through our principles based in Japan, Korea, and Europe.

We have been working on all models of compressors including Ariel, Cummins, Kirloskar, Samson, Porter-Cable, Stanley Bostitch, Campbell Hausfeld, DeWalt, Makita, Senco, ANEST IWATA, Gardner Denver, Graham Sulzer, Hitachi, Rolair Systems, Brehob, Lufkin, Zebra, Ingersoll Rand, etc
