Wärtsilä receives an order for dual fuel marine engines for 15 inland waterway barges

August 31 13:06:31, 2019

Thanks to the Wärtsilä 20DF dual fuel engine, Wärtsilä has extended the advantages of dual fuel technology to cover the entire power range.
A series of 15 inland waterway barges built for Plouvier Transport NV in Belgium and leased by Shell Trading Rotterdam will be powered by Wärtsilä dual-fuel marine engines. These barges will mainly use LNG as fuel. Wärtsilä will also provide other propulsion equipment and its LNGPac gas treatment system. The hulls of these barges are being built at the CENTROMOST VEKA shipyard in Poland and will be installed at the Werkendam VEKA shipyard. The contract was signed with Wärtsilä in December last year.
It is reported that Wärtsilä will provide a 6-cylinder Wärtsilä 20DF dual-fuel main engine, a gearbox, an LNGPac gas treatment system and a Wärtsilä propeller with a HR nozzle for each barge. These equipment will be delivered to the shipyard in June 2016.

Steel cage spherical Roller Bearing, which have two rows of barrel shaped symmetrical rollers, and held in a brass cage without fixed middle block. a common sphered outer ring raceway and two inner ring raceways inclined at an angle to the bearing axis .Therefore, spherical roller bearings are self-aligning and insensitive to misalignment of the shaft relative to the housing, The center point of the sphere in the outer ring raceway is at the roller bearing axis. modified line contact between rollers and internal & external ring to achieve maximum loading capacity. mainly bear radial load.

Steel Cage Spherical Roller Bearing

Feature:

Both the dynamic load rating and rating life equations contain no difference regarding cage design and material (brass or steel).

 

Design used for medium size bearings operating at medium to high speeds and featuring high load carrying capacities

Two-piece window type pressed steel cage guided on the inner ring

 

When the rolling bearing is equipped with a steel cage, hard contaminants might appear as a result of the adhesive wear at the cage-rolling element contact.

 

Consequently the cage design has evolved to achieve higher and higher bearing load rating capacities, by incorporating more rollers, and lower costs, by replacing brass with cheaper low carbon steel, probably also for reasons connected to the economies of scale pursued by the biggest bearing manufacturers.

 

APPLICATION:

Spherical Roller Bearing are available with heavy duty rollers and cages that are suitable for extreme demand harsh applications such as vibratory screens. Mining Conveyor Machine, and mining bulk Conveyor Pulley. In this sort of aggressive operational environment, the spherical roller bearing is the only type that delivers acceptable service life. generally have a longer life span than other bearing types.
