Overview

ISO 16123:2025 - Ships and marine technology - Marine cranes - Slewing bearings - defines requirements for the design, manufacture, inspection, testing, marking, packaging, transportation, storage, installation and maintenance of slewing bearings used on marine cranes. The standard applies to slewing bearings intended to operate at ambient temperatures down to −40 °C and covers classification, designation and acceptance criteria for single‑row four‑point contact ball, double‑row reducing ball and three‑row cross‑roller slewing bearings.

Key topics and technical requirements

Classification & designation: model representation and marking conventions (example: Crane slewing bearing‑ISO 16123‑03‑1‑40–2500) for internal/external gear, rolling element size and raceway diameter.

Load ratings: static and dynamic load rating calculations referenced to ISO 76 and ISO 16281.

Rolling elements: material and tolerance requirements (bearing steels per ISO 683‑17, steel balls to ISO 3290‑1), cylindrical roller tolerances and residual magnetism limits.

Bearing rings, cage/separator, seals and oil cups: material, geometry and performance criteria; gear surfaces and raceway heat treatment requirements are addressed.

Accuracy & lubrication: rotation/runout accuracy classes, clearance, gearing accuracy and lubrication specifications for reliable operation.

Inspection & testing methods: mandatory inspection items and NDT methods including hardness testing, penetrant and magnetic particle testing, ultrasonic testing, Charpy/impact energy verification, depth of hardening and dimensional checks.

Marking, packaging, transport and storage: requirements to ensure traceability and prevent damage during delivery and lay‑up.

Installation & maintenance: guidance for proper assembly, commissioning and in‑service maintenance (informative Annex A).

Applications and practical value

Ensures consistent safety, performance and interchangeability of marine crane slewing bearings used on offshore vessels, cargo ships, platform cranes and quay cranes.

Enables manufacturers and suppliers to certify products to a recognized international benchmark for durability, load capacity and low‑temperature operation.

Provides shipyards, crane OEMs and owners with acceptance criteria for procurement, installation checks and routine maintenance plans.

Supports classification societies and inspection bodies in applying standardized test and NDT procedures during surveys.
