SKF High Temperature Deep Groove Ball Bearings
The SKF range of deep groove ball bearings for high temperature applications provides solutions for various combinations of operating temperature and speed. All variants are lubricated for the life of the bearing, except for open VA201 bearings (that is, without integral shields) which require relubrication.
VA228 – SKF highest performance at temperatures up to 350 °C (660 °F)VA228 is an excellent choice for machinery operating with low speeds or oscillating movements in combination with very high operating temperatures. This bearing offers outstanding performance at temperatures up to 350 °C (660 °F) through the combination of the solid graphite cage, an adjusted high temperature bearing radial internal clearance and integral shields.
VA208 – Improved performance at temperatures up to 350 °C (660 °F)The VA208 bearing is lubricated by a segmented graphite cage. The large amount of lubricating graphite gives a long service life at temperatures up to 350 °C (660 °F).
VA201 – Basic performance at temperatures up to 250 °C (480 °F)The VA201 bearing is lubricated with a polyalkylene glycol/graphite mixture suitable for temperatures up to 250 °C (480 °F). Version VA201 is an open bearing (without shields) while the 2Z/VA201 has an integral shield on both sides. Both versions are supplied pre-filled with lubricant. VA201 can be re-lubricated whilst-2Z/ VA201 is lubricated for the life of the bearing. Depending on the speed and operating temperature, a special running-in procedure might be required
