1. Thrust angle touch ball bearing thrust angle in NTN bearing The contact angle of the ball bearing is usually 60°. The commonly used thrust angle touch ball bearing is usually a two-way thrust angle touch ball bearing; the first is used for fine machine tool spindle; usually with double row cylinder Roller bearings work together; can accept two-way axial load; with high precision; good rigidity; low temperature rise; high speed; easy to assemble and disassemble.
2. Deep groove ball bearings in NTN bearings In the layout, each ferrule of deep groove ball bearings has a groove-type raceway with a cross-section of approximately one-third of the circumference of the equator of the ball. Deep groove ball bearings are the primary Used to accept radial loads; also accepts a certain axial load. When the radial clearance of the bearing increases; has the property of angular touch ball bearings; can accept the axial load alternating in two directions. Comparison of other types of bearings; friction coefficient of this type of bearing. 俑撸痪 俑撸痪 撸 撸 怯 ⌒ ⌒ ⌒ 〉 〉 〉 〉 〉 〉 〉 〉 〉 〉 〉 深 深 深 深 深 深 深 深 深 深 深 深 深 深 深 深 深 深 深 深 深 深 深A wide range of NTN bearings.
3. Thrust tapered roller bearings in NTN bearings Because the rolling body in the thrust tapered roller bearing is a tapered roller; in the layout, the rolling busbars of the rolling busbar and the washer are all connected to a point on the axial center of the bearing; Therefore, the tumbling appearance can constitute a pure tumbling, the limit rotation speed is higher than the thrust cylindrical roller bearing. Features: The thrust tapered roller bearing can accept one-way axial load. The type of thrust tapered roller bearing is 90000.
4, NTN bearing double row tapered roller bearing layout, functional characteristics Double row tapered roller bearing layout is complicated; the largest amount is 35000 type; there is a double raceway outer ring and two inner rings; between the two inner rings There is a spacer; the thickness of the spacer can be adjusted to adjust the clearance. These bearings can accept the biaxial axial load together with the radial load; the axial displacement of the shaft and the outer casing can be constrained within the axial clearance of the bearing. The layout characteristics of tapered roller bearings. The type of tapered roller bearing is 30,000; the tapered roller bearing is a separate bearing. The tapered roller bearing is mainly used to accept radial and axial combined loads mainly based on radial load. Compared with the angular touch ball bearing, the bearing capacity is large; the limit rotation speed is low. The tapered roller bearing can accept the axial load in one direction; it can restrain the axial displacement of the shaft or the casing in one direction.
