SKF, the knowledge engineering company, introduced offerings to improve the reliability, safety and performance of jack-up gearboxes. These are used in the offshore oil and gas industry for Mobile Offshore Drilling Units, and in the renewable energy industry in the liftboats for the construction of offshore wind turbines.
The product solution includes the CARB toroidal roller bearings and SKF Explorer Spherical Roller Bearings (SRB), which have been proven in many of the most challenging applications, plus high performance seals. Unlike the traditional bearing arrangements used in jack up gearboxes, the CARB enables an improved gear-to-gear contact during severe load conditions and a greater load carrying capacity. This plays an important role in extending the total system life while reducing the risk of failure. Both CARB and Spherichal Roller Bearings feature the latest Explorer upgrade to a new generation of high performance bearing steels, manufactured using an improved heat treatment process.
Also available in the latest SKF offer is the HDSF2 large diameter seal, which incorporates a primary flouro-rubber sealing lip, PTFE excluder lip and chrome plated, carbon steel wear sleeve to prevent the ingress of contaminants and protect the integrity of the gearbox units. Furthermore, SKF lubrication solutions include automatic systems to keep the rack and pinion gear assembly precisely lubricated, thereby increasing productivity, reducing labour and improving safety.
