Company: WuXi JOBST BEARING CO.,LTD Located in WuXi, China, JOBST Bearings is a leading bearing manufacturer that only offers the latest, state of the art ball bearings and roller bearings around the world. From miniature bearings to huge heavy industry bearings, we're committed to providing our customers with only the best. Key Words: China Bearing; Cheap Bearings; 6203 Bearing Website: www.bearing-china.cc Installation Tips High-speed precision angular contact ball bearings, mainly for high-speed rotating light load situations requiring high precision bearings, high speed, low vibration, low temperature rise and a certain life. Often high-speed spindle bearing installed in pairs, the inner surface grinder spindle speed key component parts. Main Specifications: 1. Bearing accuracy indicators: more than GB / 307.1-94 P4-level accuracy 2. High-speed performance: dmN value of 1.3 ~ 1.8x 106 / min 3. life (average):> 1500 h Precautions: High-speed precision angular contact ball bearing life of a great relationship with the installation, you should note the following 1. Bearing installation should be in clean, clean a room, to go through carefully matching bearing, bearing spacer to go through the grind, while maintaining the inner and outer ring spacers contour premise spacer parallelism should be controlled in 1um the following; 2. The bearings should be cleaned before installation clean, cleaning the inner slope upward, feel should be flexible, no sense of stagnation, dried, placed in a predetermined amount of oil, oil mist lubrication should be placed in the case of a small amount of oil mist; 3. Install bearing special tools should be used, even by force, non-beat; 4. Bearings shall be stored in clean and ventilated, non-corrosive gases, relative humidity not more than 65% of long-term storage should be regularly rust. Maintenance 1, when the bearing is run to a certain period of time (maintenance or warranty support period), all bearing removed; 2, cleaning with diesel or kerosene soaked cleaning bearings, if technical conditions are preferably sealed cover cleaning; 3, air dry after cleaning cleaning the oil, check the appearance of damage; 4, with about a 150mm, diameter angular contact ball bearing diameter equal to the stick (preferably hollow tube), one end of a fixed bearing; 5, hand fast rolling bearing, while the stick (woodwind) at the other end of the audio amplifier microphone on top or on the ear to listen to debate the bearing rotation noise; 6, after the fixed lateral slide bearing sticks, check whether the bearing wear loose; 7, serious loose rotation noise is too large, there is a serious defect FAG bearings should be eliminated, replaced with the same model; 8, take a bucket of the amount of grease (high yellow grease) with gentle heat to melt (non-thermal), will detect over-bearing into the bucket to soak no bubbles overflow. Cooling before removing grease bearing grease residue less. After cooling remove grease angular contact ball bearings, grease residue quantity. Determine how much grease residues as required. 9, with a soft cloth or tissue to wipe the outside of the bearing grease FAG Bearings will fit into the pulley undisturbed security, maintenance work is completed.
