Marine Engine Spares and Crankpin Bearings Manufacturer & Supplier
When we attend an engine overhaul, one of the first concerns is the availability of reliable marine engine spares and crankpin bearings. Whether the work is done during drydock or under tight operational timelines, the replacement components must meet OEM tolerances and be ready for installation without unnecessary rework. From our experience working with marine diesel engines, properly inspected spares reduce downtime, simplify installation, and help prevent repeat failures after commissioning.
RA Power Solutions has long-standing associations with ship-breaking yards at Alang, India, and Bangladesh, enabling us to source quality new and reconditioned marine engine spares. In addition to supplying marine engine components worldwide, we are specialist manufacturers of crankpin bearings, including white metal, bi-metal, and tri-metal bearings for marine and industrial engines.
