A Canadian Coast Guard (CCG) icebreaker is helping to keep shipping moving on the Great Lakes throughout the winter with a set of Thordon Bearings’ propeller shaft bearings that were fitted more than 30 years ago.
加拿大海岸警卫队（CCGS）Griffon是CCG类型1100系列的最古老的船只，是1990年的一套四个Thordon XL聚合物玻璃轴承，20年，进入她的使用寿命。姐妹船在整个20世纪80年代遍布新的新轴承。自这个初步安装以来，Thordon和CCG在几个项目上共同努力，包括一些由Thordon开创的新技术。
Regular maintenance inspections over the last three decades have shown only a gradual increase in clearance between the propeller shafts and the bearings.
CCGS Griffon is about to undergo a ten-year life extension program with the CCG, for the first time, considering replacing the XL bearings like for like. Replacing the bearing staves with new XL bearings ensures the ease of installation, further reliability as well as supportability as Thordon has an extensive distributor network in Canada.
CCG中央地区的高级船只维护经理Mike Rankin评论：“我认为我们从未需要备件的事实说明这些轴承的可靠性。”
Since those early orders from the CCG, Thordon Bearings’ products are now fitted to more than 50 Navies and Coast Guards around the world, in addition to thousands of commercial merchant shipping vessels and cruise liners, thanks to their proven quality and durability – including the 30-plus years of service life on CCGS Griffon.
Scott Groves, VP – Sales for Thordon Bearings, said: “Since its first contract with the Coast Guard in the 1980s, Thordon has expanded and currently supplies over 50 navies and coast guards across the world with bearings for a wide range of vessels.
“CCGS Griffon上的Thordon轴承的经验强调了我们差不多40年前所做的事情很大，并继续伟大 - 并且只通过条件监测等发展改善了。”
CCGS Griffon, which entered service in December 1970, is a high endurance multi-tasked vessel and light icebreaker based out of Prescott, Ontario. It provides icebreaking services on the Great Lakes during the winter months, and works as a buoy tending vessel between spring and fall each year.
The four Thordon bearings are fore and aft on each of the two 457mm (18-in.) propeller shafts that are powered by four Fairbanks-Morse 38D8-1/8 8-cylinder diesel-electric generators. The 71.3m (234-ft) LOA vessel is rated Arctic Class 2, carries a crew of 25, has a maximum speed of 14 knots, and a maximum range of 5,500 nautical miles.
While Thordon’s extensive product range is in service with customers throughout Canada, 95% of the company’s manufacturing output is exported from its facility in Burlington.
