A bearing is a machine element that constrains relative movement to the desired motion and reduces friction between moving parts. The design of the bearing may, for example, provide for free linear movement of the moving part or for free rotation around a fixed axis; or, it may prevent a motion by controlling the vectors of normal forces that bear on the moving parts. Most bearings facilitate the desired motion by minimizing friction. Bearings are classified broadly according to the type of operation, the motions allowed, or to the directions of the loads (forces) applied to the parts.

Our company is an expert in bearings products. In the ZVL catalog below you will find the different models of ball and roller bearings included all types.

​

​​

• Single Row Deep Groove Ball Bearings:

​

They can carry axial and radial loads in both directions and are suitable even for high rotation speeds. These bearings are manufactured in a broad selection of types and are the most common rolling bearing type. (For more information please download the catalog mentioned below and open page 83)

​

• Single Row Angular Contact Ball Bearings.

​​

Single row angular contact ball bearings designated for high rotation  speed and high precision of seating differ from standard​ angular contact ball bearings by inner design of bearing rings, contact angle dimension of the ball with the raceways​ of the rings, construction of cage, high precision degree of operation. The bearings are non-separable and their correct arrangement assures required firmness and precision of seating.  (For more information please download the catalog mentioned below and open page 93)

​

• Single Row Four-Point Angular Contact Ball Bearings.

​

Single row four-point angular contact ball bearings are single row angular contact bearings. The raceways of these bearings are designed to accept axial load in both directions. (For more information please download the catalog mentioned below and open page 99)

​

• Double Row Angular Contact Ball Bearings. 

​

Double row angular contact ball bearings correspond with their construction and function to a pair of single row angular contact ball bearings in an “O” arrangement. They have relatively deep raceways on both rings, filling slot on one side and they are non-separable. (For more information please download the catalog mentioned below and open page 103)

​

• Double Row Self-Aligning Ball Bearings. 

 

Double row self-aligning ball bearings have spherical raceway on the outer ring. They can misalign and also the misalignment of seating is acceptable for them. Double row self-aligning ball bearings are produced with cylindrical or tapered bore and they are non-separable.(For more information please download the catalog mentioned below and open page 109)

​

• Single Row Cylindrical Roller Bearings. 

​

Single row cylindrical roller bearings are able to carry large radial load on a relatively small space. Some applications are able to carry also axial load in one or both directions. Raceways of the outer and inner rings together with the sheet profile of the cylindrical rollers in the shape of ZB allow optimal distribution of the contact pressure in the rolling space. This arrangement also allows advantageous formation of lubrication film between the contact parts of the bearing, optimal rolling, decrease of friction, growth of temperature and therefore lower stress of the junction in the arrangement.(For more information please download the catalog mentioned below and open page 115) 

​​

• Double Row Spherical Roller Bearings with Cylindrical and Tapered Bore.

​

The spherical shape of the raceway in the outer ring enables the
misalignment of the rings and ensures balanced distribution of load
over the rolling elements even under the slightest shaft deflection, or
even when the alignment of the bearing beds is not kept. (For more information please download the catalog mentioned below and open page 157)

​

• Single Direction and Double Direction Thrust Ball Bearings.

In terms of construction the thrust ball bearings are divided into single direction and double direction thrust ball bearings. (For more information please download the catalog mentioned below and open page 171)

​

• Cylindrical Roller Thrust Bearings. 

​

Cylindrical roller thrust bearings are suitable for arrangements that are stiff and can carry high loads, they are resistant to shock loads. (For more information please download the catalog mentioned below and open page 179)

​

• Spherical Roller Thrust Bearings.

​

Spherical roller thrust bearings are able to carry high axial load. Because of their construction with spherical raceways and transmission of load at a certain angle they can carry radial load as well. They are dismountable which allows simpler installation of individual rings into the arrangement. (For more information please download the catalog mentioned below and open page 185)
