LYNB tapered cylindrical roller bearings enable axially very compact bearing arrangements to be produced which can carry very heavy axial loads, are insensitive to shock loads and are stiff. LYNB produces single direction tapered roller thrust bearings and double direction tapered roller thrust bearings. The screw-down bearings constitute a special design of single direction tapered roller thrust bearing and have a full complement of rollers. They are used for rolling mill screw-down arrangements. LYNB tapered roller thrust bearings of the double direction type are mainly used together with multi-row cylindrical roller bearings in rolling mill applications. Those bearings with a plane shaft washer are the more popular as they are able to accommodate slight eccentricities of the shaft with respect to the housing bore, of the order of the radial Tipo engrenagem interna clearance of the radial bearing with which they are used. A spacer sleeve is arranged between the two housing washers. This is dimensioned so that the cover screws of the chock can be fully tightened and Tipo sem engrenagem special spring adjustment of the bearing is required.
LYNB tapered roller thrust bearings are produced with the logarithmic contact profile between raceways and rollers to guarantee optimum stress of distribution in the bearing, thus enhancing life.
LYNB tapered roller thrust bearings with cage are of separable design so that the two washers and the roller and cage thrust assembly can be mounted separately and easily. The full complement screw-down bearings are held together by special retaining components and , to simplify handling, the washers have threaded holes for eye bolts.
▲ LYNB can design and manufacture many other similar structures in accordance to the special and particular requirements of their customers’. If our customer’s have specific requests then the customer should identify the structure, and Dimensão de furos de montagem dimensions that are required. Please contact the LYNB Technical Center if you need any assistance in this area.
