Product Description

LYHY Bearing is short for LUOYANG HUAYANG SPECIAL HEAVY-DUTY AND LARGE BEARING MANUFACTURING CO., LTD.

Rolling mill bearings are very heavily loaded and subjected to high unit or specific pressure. Also, the mounting space particularly in radial direction is severely restricted. In consequence, a bearing of low sectional height yet with a very good load carrying capacity has to be provided.

The radial mounting space of a roll neck bearing is limited in that the outside diameter of the bearing is dictated by the roll body diameter minus a certain amount of stock allowed for roll regrinding and minus the wall thickness of the chock. Also, the roll neck diameter which controls the bearing bore diameter has, under high loading, to have adequate bending strength. A compromise will therefore have to be found between the diameter of the roll neck and its bending strength on the one hand and the bearing section height and its load carrying capacity on the other.
The available mounting space should be primarily used to accommodate the radial bearings since, compared to the radial loads, the axial loads are relatively small. Roller bearings have a higher load carrying capacity than ball bearings.

Cylindrical roller bearings, tapered roller bearings or spherical roller bearings, become the automatic choice for carrying the radial loads. These bearings are made of through-hardened rolling bearing steel or in some cases of casehardening steel. Four-row tapered roller bearings or
A pair of spherical roller bearings generally are loose-fitted on a cylindrical roll neck. If radial cylindrical roller bearings are used, the thrust loads have to be accommodated by a separate bearing. The provision of separate bearings. For the individual accommodation of
Radial and axial loads is particularly desirable in mills where close axial control is necessary for holding specified stock tolerances as is the case in shape-section rolling stands. Thrust bearings provide an extremely good axial guiding accuracy due to the very small or even zero axial clearance to which these bearings can be fitted. Radial bearings, on the other hand, having to perform the dual function of radial and axial guidance, will always have a larger axial clearance.

LYHY can also design and make other standard and non-standard Slewing Drives as per customer's different technical requirements. For more information about the Rolling mill bearings, please contact LYHY Bearing sales department. We will give you the best technical support.
