KOYO angular touch bearing This type of bearing is uniquely suitable for the device with combined axial and axial load conditions; it is also suitable for pure axial load working conditions, the cylindrical cylindrical bearing assembly completes axial positioning; for bidirectional axial load Three-point QJS or four-point QJF touch ball bearings should be used in the Ministry of Construction; two single-row angular touch ball bearings are also available; back-to-back or face-to-face devices; combined devices with paired or multi-row one-way angular contact ball bearings are used for high precision The axial positioning of the machine tool spindle; its axial radial clearance adjustment function is better than the three-point and four-point angular touch ball knot.
The angular touch ball bearings are: 7000C type (âˆ=15Â°), 7000AC type (âˆ=25Â°) and 7000B (âˆ=40Â°). The lock of this kind of bearing is on the outer ring; usually the inner and outer rings Can not be separated; can accept the combined load of radial and axial and the axial load in one direction. The ability to accept the axial load can be determined by the touch angle; the touch angle is large; the ability to accept the axial load is high. Axial displacement of the shaft or casing in one direction.
Corner joint ball bearings; can accept radial load and axial load together; can also accept pure axial load; high limit speed. The bearing can accept the axial load can be determined by the touch angle; the touch angle is large; the axial load is accepted The talent is high.
Angular touch ball bearings; divided into single-row angular touch ball bearings and double-row angular touch ball bearings. Single-row angular touch ball bearings are divided into two types: non-detachable and non-detachable. The inner and outer rings cannot be separated. The touch angles are 15", 25" and 40" respectively; the lock can be divided into two types on the inner ring and the outer ring. The limit rotation speed of the bearing on the inner ring is higher than the limit of the bearing on the outer ring of the lock ring. Rotating speed.
Double row angular contact ball bearings; radial and axial combined load and moment loads capable of accepting large radial loads; primarily used for components that constrain axial and axial displacement of shafts and casings.
Single-row angular touch ball bearings; when receiving radial loads; will cause additional axial forces. Therefore, they usually need to be used in pairs; the bearings of the paired devices are divided into different combinations of end faces of the outer ring: back-to-back equipment, face-to-face equipment, The series method is equipped with three types. This type of bearing can accept radial and axial combined loads with radial load; it can also accept pure radial load; except for series equipment; the other two equipments can accept either direction. Axial load.
The four-point touch ball bearing is a separate bearing; the steel ball and the bushing are four-point touch; the touch angle is 35"; it has a double semi-inner ring or a double-half outer ring type. The bearing can accept radial load and any direction. Axial load or radial and axial combined load; both single-row and double-row angular touch ball bearings; its load capacity is large; the limit speed is higher.
