One of the many issues with traditional spherical arrangements on heave compensators is that they can be very difficult to reach for standard servicing and maintenance. Due to the harsh nature of the environment, traditional spherical bearing arrangements, can and often will fail. This is due to the lack of servicing and greasing that can be applied, this can cause and exacerbate fretting or bimetallic corrosion.
Over the years Tufcot has provided many customers with our composite spherical bearings and housings to much success. However, in this application the load bearing capabilities of a complete composite arrangement won’t sustain the requirements of this offshore applications. Through years of experience in various industries, the Tufcot technical team came up with a solution.
The idea used to solve this issue brings together the best of both worlds. The load carrying capabilities of stainless steel, coupled with Tufcot's self-lubricating, no maintenance material.
To manufacture this no maintenance solution, we designed an arrangement that would use a stainless-steel ball with a composite bush pressed into the ID, coupled with a composite housing. This solution not only provides the best load carrying capabilities we have to offer, that will never need maintaining or greasing, it will also prevent fretting or bimetallic corrosion. The perfect no maintenance solution for those tough to reach spots!
