The crankpin bearing, also known as the rod bearing journal, is essential for attaching the crankshaft to the connecting rod and ensuring smooth rotation under large loads. Top-quality crankpin bearings are used in powerful diesel engines manufactured by MAK, MAN, Yanmar, and Daihatsu to reduce friction, wear, and engine failure.
RA Power Solutions: Your Trusted Source
With over 46+ years of global engineering excellence, RA Power Solutions maintains a ready stock of both standard and undersized crankpin and main journal bearings for leading engine types, including Yanmar, Daihatsu, MAK, and MAN.
Why undersized bearings matter:
- After crankshaft grinding, standard-size bearings often no longer fit.
- Ship owners can’t wait for long delivery leads—undersized bearings must be available immediately to avoid costly downtime.
Comprehensive Inventory—Models & Sizes
RA Power Solutions holds a wide range of undersize and standard bearings. A few examples include:
| Engine Make | Models & Undersize Ranges |
| Yanmar | S185L: 0.80–2.00 mm 6N18AL-DN/DV: 0.40–2.80 mm |
| Daihatsu | 6DL-16: 2.50–4.00 mm 5DC-17: 0.50–4.00 mm 5DK-20: up to 5.00 mm 8DKM-28: 0.50–4.00 mm |
| MAK | 8M20: 1.00–2.00 mm undersize |
| MAN | CME 5L 16/24: 0.50–2.50 mm 6L 23/30 H: select step undersizes 9ASL 25/30: 2.50–4.00 mm undersize |

Dubai remains our top priority market for crankpin bearing exports, given the high volume of vessel traffic through Jebel Ali and the Strait of Hormuz, where delays in bearing supply can directly affect sailing schedules.
Beyond the UAE, we regularly supply crankpin and tri-metal bearings worldwide, including Iraq, Iran, Italy, Oman, Saudi Arabia, Singapore, Russia, Qatar, Abu Dhabi, Sharjah, Ajman, Umm Al-Quwain, Fujairah, Bahrain, Gambia, Kuwait, and across the Caribbean, Southeast Asia, and Africa.
Our reach also extends to Canada, Australia, the UK, the US, Europe, and other major shipping and flag-registry hubs across Asia, the Pacific, and Latin America.
Wherever the vessel is registered or operating, we ensure OEM-spec bearings, complete certification, and export documentation are ready so customs clearance never holds up the sailing schedule.
