Wärtsilä Linesafe

LEAN PHILOSOPHY ALLOWS FLEXIBILITY
Our engineers listened to customers and developed a solution that meets market demands - the Wärtsilä Linesafe bearing. Flexibility is allowed within the standard configuration, with one bearing design suitable for multiple different configurations, such as forced lubrication or self-lubrication. This means that Wärtsilä can meet the demands of any customer, with improved response times and a first-rate product tailored to their needs. As it is fitted with the PT-100 device, the Wärtsilä Linesafe bearing comes digital-ready as standard. This allows for modern condition monitoring systems to be easily integrated. The Wärtsilä Linesafe bearing offers a lean and cost-efficient design that is flexible to specific customer needs. The customer is always in control of the final product.

Highest quality design and materials

The Wärtsilä Linesafe bearing is a fully split, hydrodynamic bearing with a self-aligning design. It consists of a modular housing made of high-quality cast iron. The plain bearing is also made of high-quality cast iron, lined with environmentally friendly white metal, giving the optimal running surface. The ideal ratio between bearing shell length to shaft diameter, along with our unique white metal application process, allows for the highest radial loads.

Features, advantages and benefits

  • New white metal application process provides greater adhesion of white metal to the bearing shell. This provides higher radial load capacity per bearing size, resulting in cost savings
  • Spherical seat accepts higher angular misalignment, which enables effective operation on ships with hull deformation. 
  • Self-aligning design ensures slight installation misalignments are corrected due to the spherical seat. 
  • Modular design gives the ability for a customer to select any optional extras they specify.
  • Upper and lower bearing shells are interchangeable. In the event of an emergency, the upper bearing shell can be used as the lower shell to support the shaft. This provides an additional level of reliability and increased safety. 
  • Temperature sensor and oil level dipstick allows for complete control of temperature and oil levels. There is no requirement to purchase extras as options come as standard.
  • One oil sump use instead of two reduces oil quantity, which can assist in lower bearing running costs.
