Product Description

Product Description

Taper roller bearings are generally used to support combined load mainly consisting of radial load.
Their cups are separable for easy assembling. During mounting and using, radial clearance and axial clearance can be adjusted and preloaded mounting can be made.

Taper roller bearings are uniquely designed to manage both thrust and radial loads on rotating shafts and in housings. Taper roller bearings are designed to carry both thrust and radial loads and consist of four components: the cone, or inner ring; the cup, or outer ring; the tapered rollers, or rolling elements; and the cage, or roller retainer.

Taper roller bearings mainly carry radial, axial combined load with radial load in the main. The capacity of axial load carrying depends on the contact angle of outer ring's raceway. The bigger the contact angle is, the greater the capacity will be.

Taper roller bearing the angle between the outer raceway generatrix and line, the bearing can bear heavy load and other Tapered Roller Bearings, it mainly bears joint load based on one-way axial load, but not only radial load.

Taper roller bearings have tapered inner and outer ring raceways, The tapered roller is in the middle of the two raceways. This kind of bearings is usually separatable, namely the retainer, inner ring and outer ring can be installed apart. They can withstand immense radial direction load and certain axial load. They are designed in different sizes and styles to meet all kinds of functions.

Basic knowledge of bearings

 

Why choose rolling bearings?

Rolling bearings support and guide the rotation or oscillation of machine components - such as axles, axles, or wheels - with minimal friction and transmit loads between machine components. Rolling bearings have high precision and low friction performance, thus achieving high rotational speeds while reducing noise, heat, energy consumption, and wear. This type of bearing is cost-effective and is a typical interchangeable machine component that meets national or international dimensional standards.

Ball and roller bearings

Distinguish the two basic types of rolling bearings using the two basic types of rolling elements:
 * Ball → Ball bearing
 * Roller → Roller bearing

The difference between a ball and a roller is the way it contacts the raceway.
The ball makes point contact with the bearing ring raceway. As the load acting on the bearing increases, the contact point becomes an elliptical area. If the contact area is small, the rolling friction is also small, which allows the ball bearing to adapt to high-speed operation, but limits its load-bearing capacity.
The roller and bearing ring raceway make line contact. As the load on the bearing increases, the contact line becomes a rectangle. Due to the larger contact area and the resulting friction, roller bearings can withstand heavier loads but lower speeds compared to ball bearings of the same size.

 

Radial and thrust bearings

 

Rolling bearings are divided into two categories based on the main load direction they bear:
  * Radial bearing
    Radial bearings can withstand loads perpendicular to the shaft. Some radial bearings can only withstand pure radial loads, while most radial bearings can also withstand axial loads in one direction, and in some cases, they can also withstand axial loads in both directions.

  * Thrust bearing
   The thrust bearing mainly bears loads along the axial direction. According to the design, thrust bearings can support unidirectional or bidirectional pure axial loads, but some can additionally withstand radial loads. Thrust bearings cannot achieve speeds as high as radial bearings of the same size.

 

   The contact angle determines which category the bearing belongs to. Bearings with a contact angle ≤ 45 ° are radial bearings, while others are thrust bearings.
