The quality of cylinder liners and cylinder sleeve is of great importance. Cylinder liners and cylinder sleeves manufactured and exported by RA Power Solutions have the OEM tolerances and standard. The cylinder liners are manufactured by centrifugal process and in-house machining maintaining the tolerances is done. The honing of cylinder liner is of great importance. The Chris Marine honing machines are used to maintain the criss cross pattern which is essentially required for retaining of oil.
We manufacture cylinder liners up to the length of 1500 mm irrespective of their material composition and design. The cylinder liners and cylinder sleeves for all popular makes of engine and their models are available ex-stock. RA Power Solutions also manufactures cylinder liners according to the sample or the manufacturing drawing provided by the user. Cylinder liners and cylinder sleeves for various applications including compressors, forging hammers are manufactured.
The cost of cylinder liners is low in comparison to liners supplied by engine manufacturer. Thus it results to considerable reduction in the cost.
The cylinder liners are exported all over the world. Each cylinder liner prior to dispatch is subject to dimensional inspection by quality control department. The inspection reports are shared with the client.
We stand guarantee for the satisfactory performance of liners for the period of 18 months from the date of dispatch or 6000 hours of operation whichever is earlier.
II) It is possible to replace the large portion of damaged components by using new casting piece, this is done by metal stitching and metal locking process.
III) Metal stitching and metal locking is the most trusted technology of crack repair as no heat is generated. It is a cold process and there is no change in the shape and profile of the component unlike in the welding process.
IV) Repair of crack by metal stitching and metal locking is possible onsite without disassembly of the equipment.
Reduce cost and breakdown time by Onsite Repair of Crankshaft
The failure of crankpin and main journal bearing causes serious damage to the crankshaft which are as following:
I) Development of excessive taper and ovality in Crankshaft, Crankpin and Main Journal.
II) Development of crack
III) Abnormal increase and decrease of hardness
IV) Loss of alignment of crankshaft resulting to the increase in deflection readings.
V) Development of bearing line marks, pitting, local depression
VI) Damage of radius fillet and lube oil profile
The removal of crankshaft from the engine block inevitably means high cost and disruption due to transportation and repair in the designated workshop. Removing and sending the crankshaft for repair to the workshop is now outdated.
RA Power Solutions Pvt. Ltd undertakes crankshaft repair onsite without removing it from engine block. The onsite crankshaft repair equipment is placed on the damaged crankpin through the inspection window of the engine block and the grinding is undertaken.
The onsite crankshaft grinding equipment developed and manufactured by us is capable to undertake grinding and polishing of crankshaft in one setting. The tolerances after crankshaft repair are strictly maintained as per the manufacturer’s specifications.
We have highly trained skilled team of technicians who are deputed to the plant site or on a vessel in a minimum possible time. The process followed by us for repair of crankshaft is faster, more cost effective and convenient. It ofcourse avoids removal of crankshaft and transport to the workshop.
The repair of crankshaft executed by RA Power Solutions Pvt. Ltd is approved by leading inspection agencies including Lloyds, DNV and many other inspecting agencies.

Few years back, it was mandatory to send the damaged turbine shaft to the workshop for repairs. This involved dis assembly of complete turbine, removal of turbine shaft from the block, packing and transportation to the workshop.
A new technology has been introduced in recent years. Turbine shaft grinding machine designed is portable; light weight and can be taken to the site. The main feature of turbine shaft grinding machine is that it can be placed on the turbine shaft bearing sitting diameters and grinding and polishing can be done without dis assembly of turbine shaft. This process of grinding and polishing of turbine shaft by the portable turbine shaft grinding machine saves downtime and cost.
RA Power Solutions design and manufactures turbine shaft grinding machine. The machine is capable to undertake grinding of turbine shaft, crankshaft, alternator shaft & cylindrical shaft up to 700 mm. The turbine shaft grinding machine is priced economically and can be delivered in short time. It is highly recommended for power plants, shipping companies, workshops undertaking repairs, etc.
RA Power Solutions Pvt. Ltd. has sold more than 60 onsite turbine shaft grinding machines across the world.
