This class is designed to make the inner bearing raceway, outer raceway and the apex of the cone surface roller rolling surfaces intersect at a point bearing center line. In addition to metric series, there are a variety of British products. Suitable to withstand heavy load and shock load. In addition to single row tapered roller bearings bearings, there are double row bearings, pairs of double bearings and four bearings. Tapered roller bearing cage generally use stamping cage. 30202DZ series spindle bearings are mainly used for cotton, wool, linen, silk, chemical fiber, spinning pure, blended spinning and twisting machine, such as supporting the use of textile machinery spindles. For those cotton spinning enterprises, how to better use, care and maintenance of these special pieces of good is very important. In this, mainly from the perspective of product manufacturers and with the user's usage, to talk about the use of spindle bearing products, maintenance
