Intermediate Bearing

Decision Guide: Choose if: you need a proven, cost‑effective intermediate bearing for a 150 mm shaft and can provide external sealing/lubrication. Avoid if: the application demands sealed units, higher load capacity, or advanced low‑friction materials.

Decision Guide: Choose if the vessel requires a compact intermediate bearing for a 200 mm shaft, operates within conventional speed/temperature limits and can accommodate an external seal. Avoid if you need an integrated sealed unit, higher‑speed capability or documented load ratings without further manufacturer verification.

Decision Guide: Choose if: you need a standard‑size, cost‑effective intermediate bearing for a 250 mm shaft on medium‑speed diesel propulsion with moderate load and temperature requirements. Avoid if: the installation demands sealed bearings, operates at very high temperatures or speeds, or requires higher load capacity than white‑metal can provide.

Decision Guide: Choose the IB-300 when a compact, 300 mm intermediate bearing is needed and external sealing can be provided; avoid it for high‑load applications or where an integrated seal is required.

Decision Guide: Choose if: you need a compact intermediate bearing for a 400 mm shaft on a medium‑speed merchant vessel and can provide external sealing. Avoid if: the propulsion line operates at high RPMs, requires an integrated seal, or demands a bearing material with higher fatigue resistance.

Decision Guide: Choose if: you need a proven, high‑load bearing for a 500 mm shaft on a large ocean‑going vessel and have an established oil‑lubrication maintenance regime. Avoid if: space or weight are critical, you prefer low‑maintenance polymer bearings, or the propulsion system operates at very high speeds.

Decision Guide: Choose if: you need a proven, high‑capacity bearing for a 600 mm shaft on vessels with conventional propulsion layouts and can provide reliable lubrication. Avoid if: the installation demands very high rotational speeds, weight savings, or integrated sealing solutions that are not available for this model.

Decision Guide: Choose if: the propulsion shaft is 700 mm in diameter, you need a high‑load white‑metal bearing and have space for a 1.4 m intermediate unit, and your vessel already uses Aegir Marine shaft line components. Avoid if: an integral oil seal is mandatory, the shaft operates at very high RPM where lower‑friction materials are preferred, or you require a lightweight alternative to white metal.

Decision Guide: Choose if: you need a proven, white‑metal intermediate bearing for an 800 mm shaft on large commercial or offshore vessels and can provide external sealing. Avoid if: the installation requires integrated seals, operates at very high shaft speeds, or demands lightweight/high‑temperature materials.

Decision Guide: Choose if: you need a compact, proven intermediate bearing for a 100 mm shaft and are already using Pacific Marine shaft‑line components. Avoid if: the installation demands an integrated seal, operates at very high RPMs, or you prefer low‑maintenance polymer bearings.

Decision Guide: Choose if you need a standard‑size (150 mm) intermediate bearing with a compact profile and are already using Pacific Marine shaft line components. Avoid if the propulsion system operates at very high loads or speeds, requires an integral seal, or must meet specific classification society approvals that are not documented for this model.

Decision Guide: Choose the PM IB-200 when a cost‑effective, high‑load intermediate bearing is needed for a 200 mm shaft operating at moderate speeds on vessels with established oil lubrication systems. Avoid it in high‑speed propulsion lines, in environments where water ingress is likely without additional sealing, or where extended maintenance intervals are required.

Decision Guide: Choose if: you need a reliable, standard‑size intermediate bearing for a 250 mm shaft on medium‑speed diesel propulsion and prefer a proven white‑metal design with easy inspection. Avoid if: the installation requires integrated sealing, operates at very high shaft speeds, or weight savings are critical.

Decision Guide: Choose if you need a proven, standard‑size intermediate bearing for a 300 mm shaft on a conventional propulsion line and can provide an external seal. Avoid if the installation demands a fully sealed bearing, operates at very high RPMs, or requires exotic materials for extreme temperature or corrosion environments.

Decision Guide: Choose if: you need an intermediate support for a 400 mm propulsion shaft on vessels with long shaft runs and you have a maintenance regime that can manage open‑type bearings. Avoid if: the installation requires a sealed bearing, the shaft size differs from 400 mm, or you prefer a hybrid/ceramic bearing for extended dry‑run life.

Decision Guide: Choose if: you need a standard, non‑sealed intermediate bearing for a 500 mm shaft on vessels where space is limited and operating speeds are moderate. Avoid if: the application demands an integrated seal, very high speed operation, or higher load capacity than white‑metal can reliably provide.

Decision Guide: Choose if: you need a standard‑size, high‑load intermediate bearing for a 600 mm shaft on a conventional diesel propulsion system and can provide routine lubrication/maintenance. Avoid if: you require a sealed, low‑maintenance or lightweight bearing solution for very high‑speed or temperature‑sensitive applications.
