Single-row cylindrical bearing ups spindle speeds
A completely new kind of high precision cylindrical roller bearing, developed by SKF, enables high-speed spindles to achieve very high rigidity without design compromise.
Fan upgrades cut maintenance costs
SKF fan upgrade solutions employ self-aligning bearings, advanced plummer (pillow) block housings and automatic lubrication systems.
Seals boost food production safey
SKF Economos' new seals can be quickly and simply found with standard metal detection equipment should any small pieces fall into the product being processed.
Its design brief called for a decrease in the measuring point of wind speed, better protection for the bearings from the effect of salt water and an increase the service life.
It also needed two such spindles, to cope with both wind speed and direction.
SKF had to address those needs in combination with a ready-to-mount, self-contained, maintenance-free design that exhibited low friction.
It set up a special design team, with members from different disciplines within the company, and set to work.
Raymarine originally presumed that it would need a hybrid (ceramic) bearing for the spindle, but, after significant analysis and development work SKF was able to offer a complete unit that comprised two shielded stainless steel deep groove ball bearings, a shaft, springs and a two-part, snap together plastic housing.
Shielded bearings were used instead of separate seals because additional seals would increase friction on the shaft.
A labyrinth seal was used to prevent water ingress.
Benefits to Raymarine from the new solution from SKF include a reduced number of suppliers, fewer problems and a longer life.
This project was a success because SKF was able to call on all of its expertise across a great many disciplines.
The company was able to help with many facets of the anemometer's evolution from design and development through to its manufacture and assembly.
The end product meets all of the functional needs as well as offering Raymarine the advantages of reduced logistics and administrative costs said SKF. Request a free brochure from SKF UK ...
