    Significant design advances create a bearing that is lighter, more durable and easier to install and maintain

    Gothenburg, Sweden, 8 September 2016: At the SMM 2016 trade fair (Hamburg, 6-9 September), SKF is announcing the launch of its 4th generation Simplex intermediate shaft bearing for propulsion shaft lines. The new bearing features multiple design changes and improvements, to provide superior durability, reliability and ease of installation and maintenance for vessel builders and operators.

    Those improvements begin at the housing. The revised design is stiffer and around 50kg lighter (in the case of a mid-sized 550 unit) than its predecessor. The redesign of the seal enables an easier installation or replacement by vessel crews, as does a new dowel pin design that can be pushed through the housing. The bearing shell is now solely made of steel rather than cast iron and is secured with a new positive locking mechanism.

    Further weight savings and installation improvements have been achieved with a new chock liner design. The revised steel chock liners are around 30 percent lighter and identical liners are used in every location, with their position clearly indicated on the bearing unit. The bearing can be mounted on conventional steel chocks or in a tripod configuration using easily re-adjustable and re-usable SKF Vibracon chocks, which are surface treated to resist corrosion and enhance the durability of the mounting system. Casting with epoxy resin is also possible.

    Other changes to facilitate assembly and maintenance include a simplified seal design and a new top-mounted transparent oil scraper cover that allows easy inspection and straightforward access. A new, larger 6mm temperature sensor comes with cables attached to a terminal strip and an IP67 rated junction box. A 2x3 wire dual sensor is available as an option. The integrated cooling coil uses robust, simplified connections protected against damage by overtightening or external impacts.

    Overall, the new SKF Simplex intermediate shaft bearing offers significant payback time and total lifecycle cost benefits, from fast installation at the shipyard, to a long operating life and easy maintenance.
