High-temperature BW Angular Contact Ball Bearings

High-temperature angular contact ball bearing national standard size, the same type of any national standard bearings can be replaced, is a more general type of high-temperature conditions use, divided into single-row and double-row, four-point angular contact, high-temperature conditions are divided into high-speed and low-speed, corresponding to the cage and full ball structure, working temperature range 150 ° ~ 1200 °, according to different materials to meet the requirements, support non-standard custom!

High temperature angular contact ball bearings in the kiln car, blast furnace or paint spraying equipment and other transmission systems, bearings must work in extremely high temperature, or must withstand a great temperature difference, ordinary bearings are not applicable, high temperature bearings mainly through bearing materials, structure, internal process dimensions, lubrication conditions four aspects of optimal design, a greater degree to meet a variety of different working conditions requirements.
High temperature high speed angular contact ball bearing: with stamping steel cage, lubricated by high quality white high temperature grease, this grease is based on fluorinated polyether oil mixed with PTFE, which can meet the working conditions within 300℃ and DN value about 100,000.
Super high temperature and heavy load low speed angular contact ball bearing: without cage, fully loaded rolling body, the load is 1.4 times of the bearing with cage. Lubricated with black high temperature grease, this lubricant is a mixture of polydiol and graphite. At 200℃ or above, no residual volatilization of polydiol, forming graphite solid lubrication. It is suitable for the working condition within 500℃ and speed＜100r/min. It is usually checked once about 2 months of operation. If there is no longer a dry lubricating film shown by shiny metal flash marks on the raceway, the above high temperature grease lubrication should be added.
