Pillow block bearing lubrication maintenance of heating methods

Initial radial clearance for spherical roller bearings in the push in the process of gradually reducing and pushing in the volume determined by the size of the tie level. Therefore, prior to installation, you must first measure the initial radial clearance of spherical roller bearings. Push the bearing process, continuous measurement of radial clearance, until it reaches the required reduction of radial clearance and interference fit is ideal so far.
Due to temperature, speed, load, lubrication and environmental impact. Of fatigue life of rolling bearings lubrication on bearing lubrication and friction, abrasion, temperature, vibration, and so have an important impact, not lubricated properly, with spherical bearings will not work. Causes analysis of bearing damage showed that associated 40% left and right bearing damage and poor lubrication.
Application procedure with spherical bearings, special is for bearing lubrication time, pay attention to amount of grease. What precisely the use of grease, fill in the movement of rolling bearing grease, bearing changes can generally be divided into two stages. Bearing grease in the bearing that form the outline of the differences are differences of the opening, must constitute the outline draft should be time to go short, and in fact moving in the pillow block bearing temperature is low and smooth, this is a fantasy of grease, so the bearing grease into drains special primary.
Under special conditions, the lubricant must be made the following special requirements:
1, long-life requirements of particularly long service life of the lubricant.
2, soundness requirements
3, low temperature requirements the ability-63 under the low temperature.
4, low friction torque requirements of low friction of lubricants.
5, boundary lubrication characteristics of good requirements
6, heat resistance requirements can do more than 250 ℃ high temperature.
7, high vacuum requirements under conditions of high vacuum, is not volatile, not lost, not bad, especially under high vacuum conditions of weightlessness.
