Imported bearing structure and performance characteristics

Characteristics of the structure and performance of imported bearings 1. Axial angular contact ball bearings in imported bearings Axial angular contact ball bearings The contact angle is generally 60°. The commonly used thrust angular contact ball bearings are generally two-way thrust angular contact ball bearings and are mainly used for precision machine tools. Spindle, generally used with double row cylindrical roller bearings, can withstand two-way axial load, with high precision, good rigidity, low temperature rise, high speed, easy assembly and disassembly.

2. Deep Groove Ball Bearings in Imported Bearings Each ring of a deep groove ball bearing in the structure has a cross-section approximately of stainless steel pipe fittings. Com stainless steel elbow is a continuous groove type raceway with a third of the equatorial circumference of the ball. Deep groove ball bearings are mainly used to withstand radial loads and can also withstand certain axial loads. When the radial clearance of the bearing increases, it has the properties of angular contact ball bearings and can withstand alternating axial loads in both directions. Compared with other types of bearings with the same size, this type of bearing has a small coefficient of friction, high limit rotation speed and high precision, and is the preferred type of bearing for user selection. Deep groove ball bearings are simple in structure and easy to use. They are the largest production batch and the most widely used type of imported bearings.

3. Thrust tapered roller bearings in imported bearings As the rolling elements in the thrust tapered roller bearings are tapered roller hygienic butterfly valves. Com Stainless steel pipe fittings, the rolling busbars of the rolling busbars and washers on the structure meet at a certain point on the axle line of the bearing, so the rolling surface can form a pure rolling, and the rotational speed is higher than the thrust cylindrical roller bearings. Features: Thrust tapered roller bearings can withstand one-way axial load. Thrust tapered roller bearing type code 90000.

4. Structure and performance characteristics of double-row tapered roller bearings in imported bearings The double-row tapered roller bearings have a variety of structures. The maximum amount is 35000 type. There is a double raceway outer ring and two inner rings, between the two inner rings. There is a spacer, change the thickness of the spacer to adjust the clearance. This type of bearing can bear two-way axial load while bearing radial load, and can limit axial displacement of the shaft and housing within the axial clearance of the bearing. Tapered roller bearing structure features. Stainless steel elbow. The com butt welded tapered roller bearings are code-named 30,000, and tapered roller bearings are separate bearings. Tapered roller bearings are mainly used to withstand the radial and axial combined load mainly radial load. Compared with angular contact ball bearings, the bearing capacity is large and the limiting speed is low. Tapered roller bearings can withstand axial loads in one direction and can limit the axial displacement of a shaft or housing in one direction.
