Thordon’s heavy-duty elastomeric bearing materials have been keeping the Comeau Marine Railway operational under locally concentrated loads and in some of the harshest, abrasive waterways for more than forty years.
Comeau Marine’s 600t-capacity railway, one of Nova Scotia’s oldest patent slips, operates year-round to maintain and service much of the inshore fishing fleet as well as parent company Comeau’s Sea Foods Ltd.’s fishing fleet.
“The patent slip, or marine railway, a cost-effective alternative to a conventional drydock or synchrolift, uses a large cradle on rolling stock to hoist vessels out of the water up an inclined rail track,” said Thom Hofmann, President, Avalon Marine, Thordon Bearings’ Nova Scotia-based distributor.
“Over the past 40 years, the railway has used all types of bearings, including phenolics, bronze, Lubrite, but as far as I can tell the best success the yard has had has been with ThorPlas-Blue.”
该应用程序也使用了Thordon的XL和SXL轴承，但在2018年，Comeau决定将直径110毫米（4.3英寸）直径的Thrplas-Blue轴承安装在船舶摇篮高载轮的关键区域。
霍夫曼说：“在检查了几个轮子并研究了船的吊车如何操作之后，我们得知两艘船只经常同时装载。”“这意味着整个负载能力集中在摇篮的纵向中心部分上，需要使用极端性能轴承材料。
“全年运营的海洋铁路都位于新斯科舍省西南海岸的芬迪湾（Bay of Fundy），这一事实进一步加剧了表演。大量的磨砂沙子和沉积物经常冲向河口，最终覆盖轨道和轮子。”
霍夫曼补充说：“虽然较早的XL和SXL轴承的性能以及预期的是，摇篮需要更健壮的东西。我们考虑了许多Thordon选项，并且在考虑了商业含义之后，业主选择使用Thrplas-Blue材料，因为这是最好的选择。”
Avalon designed the bearings and supplied the material as rough molded tubes so the shipyard could quickly and easily machine and install the bearings between drydockings.
Comeau Marine Railway总经理Joe MacDougall以及他的助手Brian Amirault表示：“我们尚未遇到任何问题，一切都很好。Thorplas-Blue现在已经使用了几年，到目前为止，尽管负载，沙子和碎屑不均匀，材料并未失败。”
轴承的成功在很大程度上是Avalon的前期工程的结果。使用这种出色的轴承材料使Comeau能够提高轴承磨损率并减少维护时间和成本，同时大大改善了院子的性能。
Scott Groves, Thordon Bearings’ VP – Sales, added: “It is not uncommon for Thordon’s proprietary polymer bearings to be used in this type of application and other ship repair yard facilities, such as dock gates, water pumps, and cranes, largely due to the ability of the material to withstand extreme loads and abrasion.”
Thorplas-Blue是一种自润滑的聚合物轴承，能够承受以全格式的干扰拟合配置安装的高达45 MPa（6,527 psi）的操作压力。Thorplas-Blue不需要油脂以确保平稳运行。在整个均匀的Thrplas-Blue聚合物基质中配制的润滑剂，即使轴承磨损，也能确保低，稳定的摩擦系数。
