SKF Ball Bearing, Cylindrical Bore Type, 45mm ID, 85mm OD, 19mm Race Width - 6209-Z/C3 Keep things running smoothly with this ball bearing from SKF. As a deep-groove unit, it supports breakneck reference speeds of up to 17,000r/min like those found in fast-paced motors. Rest assured, it also handles impressive loads up to 35.1kN, making it ideal for heavy-duty applications. Since the assembly comes unlubricated, you can use the grease or oil best suited for your system. Once greased, you can seal the single-sided shield into your machinery to minimise maintenance. Features & Benefits • Sheet metal cage keeps spheres in line to prolong performance and service life
• Bearing steel resists wear and tear to suit use in demanding applications
• Race width of 19mm provides larger surface area for stable mounting Applications • Robotics design
• Automotive industry
• Aerospace engineering
• Manufacturing equipment What's the difference between limiting speed and reference speed? Limiting speed is how fast the bearing can run continuously without generating critical heat. For example, this bearing's reference speed of 17,000r/min is suitable for short periods, while the limiting rate of 11,000r/min can be maintained continuously.
