Model No.: 013.50.2980
Windmill slewing bearings are usually made as per single row ball Slewing Bearing structure, and most of them are external gear types,but some are internal gear types.
LYHY is specialized in producing:
Single row slewing bearing (01 series, HS series, Q series)
Single row slewing bearing has compact structure, and the ball arc raceway four-point contact. Mainly used for truck cranes, tower cranes, excavators, piling machines, construction vehicles, radar scanning equipment to withstand the overturning moment, vertical axial force, the level of force tends to machinery.
Single row cross roller type (11 series);
Single row cross roller consists of two seats, compact structure, light weight, high manufacturing precision, small assembly clearance. Install accuracy requirement is high, the roller as 1:1 cross arrangement, can bear axial force and overturning moment and larger radial force, widely used for transportation machinery, engineering machinery and military products.
Double row ball slewing bearing (02 Series);
Double-row slewing bearing has three seat, steel balls and isolation blocks can be directly discharged into the upper and lower raceway. According to the situation by force, arranged up and down two rows of different diameter steel balls. This assembly is very easy to open, the upper and lower bearing raceway arc angles are 90 °, can withstand great axial force and tilting moment. When the axial force radial force is greater than 0.1 times, the raceway must be specially designed. Double-row ball slewing bearing axial and radial dimension larger than the structure of the fastening. Especially suitable for the tower cranes, truck cranes and other handling machinery.
Three row roller sleiwng bearing (13);
Three-row roller slewing bearing has three seat, and the upper and lower radial raceway each separately so that each row roller load can be determined exactly. Able to withstand various loads. Axial and radial dimensions are larger, solid structure, especially suitable for applications requiring larger diameter heavy machinery, such as bucket wheel excavators, wheeled cranes, ship cranes, harbor cranes, steel operating table and large-tonnage truck cranes and other machinery on. Light slewing ring slewing ring having the same general structure, light weight, flexible rotation. Widely used in food machinery, filling machinery, environmental protection machinery, and other fields.
Widely used in construction machinery, construction machinery, metallurgical mining machinery, ship port machinery, environmental protection machinery, light industrial machinery, petrochemical machinery, engineering vehicles, military equipment and other industries. Product model covering 4500mm - 200mm various standard and non-standard specifications.
