ROOS-LAIS Bearings’ Ningxia plant secures an order for iron ore bearings from Australia’s Hancock Iron Ore

Ensuring the efficient operation of the world’s leading mines through bespoke technology

Recently, ROOS-LAIS Bearings’ Ningxia plant in the UK announced that it had successfully entered into a strategic partnership with Australia’s Hancock Iron Ore, securing a substantial order for specialised bearings for the company’s iron ore projects. This marks another major breakthrough for ROOS-LAIS Bearings in the global market for high-end mining equipment, with its customised technical capabilities for extreme operating conditions receiving high acclaim from leading international mining companies.

Hancock Iron Ore, a rising giant in the global mining sector, was formally established on 1 July 2025 through the merger of Roy Hill and Atlas Iron. Following the merger, the company’s annual production capacity reached 74 million tonnes, instantly making it Australia’s fourth-largest and the world’s fifth-largest iron ore producer. Its parent company is Hancock Prospecting, and its core asset, the Roy Hill mine, is one of Australia’s largest single iron ore mines, with a mining concession spanning approximately 30 kilometres, iron ore reserves exceeding 2.3 billion tonnes, and a mine life of over 17 years. Headquartered in Perth, Western Australia, the company’s core operations encompass iron ore exploration, mining, processing and global sales. Its products are renowned for their high grade and low impurity content, primarily supplying high-end steel markets in Asia, including China, Japan and South Korea, and occupying a key strategic position within the global iron ore supply chain.

汉Operations at the Hancock Iron Ore Mine are concentrated in Australia’s Pilbara region, a desert area characterised by a hot, dry climate and fierce sandstorms. Furthermore, the entire process—from iron ore extraction, crushing and grinding to transportation—is subject to extreme operating conditions involving heavy loads, severe impacts, high dust levels and intense corrosion. The equipment must operate continuously around the clock. Traditional bearings frequently fail due to rapid wear, lubrication failure and dust ingress, severely impacting production efficiency and operational costs.

In response to the harsh operating environment at the Hancock Iron Ore Mine, the technical team at the ROOS-LAIS Bearing Ningxia Plant conducted in-depth research into the operational requirements and carried out comprehensive optimisation and upgrades to the bearings:

- Innovative rolling structure: Featuring high-precision curved raceways and an optimised roller arrangement, this design significantly enhances the bearing’s resistance to impact loads and heavy-duty operation. It effectively disperses alternating stresses during equipment operation, reduces the risk of raceway fatigue spalling, and meets the demands of continuous, high-intensity mining machinery operations.

- Lubrication System Upgrade: A bespoke extreme-pressure anti-wear lubrication solution has been developed, utilising specialised grease that is heat-resistant, corrosion-resistant and offers long-term stability. Combined with internal self-lubricating channels and a multi-stage sealing structure, this design prevents the ingress of mine dust and moisture whilst ensuring the bearing maintains a complete oil film even under extreme temperatures and heavy loads, extending the lubrication maintenance cycle by more than three times.

- Enhanced Materials and Processes: High-purity bearing steel is carefully selected and undergoes specialised heat treatment to optimise internal microstructure, thereby improving bearing hardness, toughness and wear resistance. This makes the bearings suitable for the highly abrasive and corrosive operating environments of iron ore mining, effectively extending their overall service life.

The successful execution of this order represents a significant achievement of ROOS-LAIS’s ‘customised technology + premium quality’ strategy. Leveraging the advantages of localised R&D and smart manufacturing, the Ningxia plant has precisely met the stringent standards of leading international mining enterprises. This not only further consolidates ROOS-LAIS’s position in the global mining bearing market but also sets a benchmark for Chinese high-end industrial bearings entering the world’s top-tier mining supply chains. Looking ahead, ROOS-LAIS will continue to focus on the research and development of bearing technologies for extreme operating conditions, providing more reliable and efficient core component solutions for the global mining, metallurgy and heavy industry sectors.
