What do you know about taper roller auto bearings?

Taper roller auto bearing is a kind of rolling bearing and one of the most commonly used parts in modern machinery. It is based on rolling contact between the main elements to support the rotating parts. Today, rolling bearings are mostly standardized. Roller bearings have the advantages of low torque required to start, high rotational accuracy and convenient selection.

What are the common taper roller auto bearings on the market?

1. The outer ring (or inner ring) of double row taper roller auto bearing is one piece. The small end faces of the two inner rings (or outer rings) are similar, and there is a spacer in the middle. The game is adjusted by the thickness of the spacer. The preload of the double row taper roller auto bearing can also be adjusted via the thickness of the spacer piece.

   
   

2. Four row taper roller auto bearing, the performance of this bearing type is basically the same as that of double row taper roller auto bearing, but the radial load is greater than that of double row taper roller auto bearing and the limit speed is slightly lower and is mainly used for heavy machinery.

   
   

3. Multi-sealed double and four row taper roller auto bearings, ZWZ provides durable, multi-sealed double and four row taper roller auto bearings. Perform a new personalized design for the bearing, change the traditional construction method of the fully sealed bearing, and adopt a new type of sealing structure that combines seal and dust seal to improve sealing performance and improve sealing performance. Compared to open structure bearings, the multi-sealed double row and four row taper roller auto bearings have a service life of 20% to 40% and an 80% lower lubricant consumption.

What are the structural features of taper roller auto bearing?

taper roller auto bearings mainly carry the combined radial and axial loads mainly in the radial direction. The load-bearing capacity depends on the raceway angle of the outer ring, and the greater the angle, the greater the load-bearing capacity. This type of bearing is a dismountable bearing which is divided into single row, double row and four row taper roller auto bearings depending on the number of rows of rolling elements in the bearing. The play of single row taper roller auto bearings must be set by the user during installation; The play of double row and four row taper roller auto bearings was set according to the user's requirements when the product leaves the factory, and does not need to be adjusted by the user.

What is the definition of the suffix of taper roller auto bearing?

A: Internal structural change

B: Increased contact angle

X: The external dimension adopts the international standard

CD: Double outer ring with oil holes or grooves.

TD: Double inner ring with tapered bore.
