JOJI bearing is a kind of high-quality bearing products widely used in machinery manufacturing, engineering technology and industrial fields, which is produced by Germany JOJI group with excellent performance and reliable quality.

I. JOJI bearings are of various types, which can be classified into the following categories according to different structures, applications and working conditions:

1, deep groove ball bearings: this is one of the most common types of bearings, it can withstand radial load and axial load, suitable for high speed and low noise occasions.JOJI deep groove ball bearings have single row and double row two kinds of structure, and there are variants with dust cover, seals, or with stop groove.

2, cylindrical roller bearings: this is a suitable for bearing high radial load bearing type, it is by the inner ring, outer ring and rolling body, rolling body is cylindrical, and bearing seat between the line contact, friction coefficient is small, high speed.JOJI cylindrical roller bearings have a single row, double rows and multiple rows of three kinds of structure, there are also with stopping grooves or without stopping groove variant.

3, tapered roller bearings: this is a kind of bearing type that can withstand radial load and axial load at the same time, it consists of inner ring, outer ring and rolling body, the rolling body is tapered, with a little bit of contact between the bearing seat, you can adjust the axial clearance between the inner ring and the outer ring. joji tapered roller bearings have a single, double and four rows of three kinds of structure, there are also variants with stop groove or without stop groove.

4, spherical roller bearings: this is a kind of automatic adjustment of the heart of the bearing type, it is by the inner ring, outer ring and rolling body, rolling body for the ball, and bearing seat between a little contact, can compensate for the bearing seat deviation, suitable for bearing heavy load and shock load occasions.JOJI spherical roller bearings with stop groove or without stop groove variant, there are with seals or without sealing ring variant.

5, thrust ball bearings: this is a kind of bearing type which can only bear one-way axial load, it is composed of bearing seat, bearing cover and rolling body, the rolling body is spherical, and the bearing seat between the point of contact, suitable for low-speed operation and low friction occasions. joji thrust ball bearings have one-way and two-way two kinds of structure, there are also with stopping groove or without stopping groove variant.

6, angular contact ball bearing: this is a kind of can bear radial load and axial load bearing type at the same time, it is by the inner circle, outer ring and rolling body, rolling body for spherical, and bearing seat between wired contact, contact angle of 15 °, 25 ° or 40 °, suitable for high speed and high precision occasions.JOJI angular contact ball bearings have a single row and two rows of two kinds of structure, there are also with stopping groove or without stopping groove variant. JOJI angular contact ball bearings have single-row and double-row structure, with or without stop groove.

7、Four point contact ball bearing: this is a kind of bearing type that can bear two-way axial load and small radial load at the same time, it consists of inner ring, outer ring and rolling body, the rolling body is spherical, there are four points of contact with the bearing seat, suitable for high speed and high rigidity occasions.JOJI four point contact ball bearing has a stop groove or no stop groove variant, and there are seals with or without sealing ring variant.

Second, the characteristics of JOJI bearings are mainly in the following aspects:

1, JOJI bearings are made of high-quality bearing steel, heat-treated and friction-welded process, with high strength and high toughness, the surface has been specially treated to increase the hardness and wear resistance, prolonging the service life, and reducing maintenance costs.

2、JOJI bearings adopt advanced processing technology, such as cold rolling process and drawing process, which optimises the shape and size of the bearings, improves the precision and performance of the bearings, reduces friction and noise, and improves the efficiency and quality of the bearings.

3、JOJI bearings adopt flexible design, according to different working conditions and needs, provide a variety of structures, sizes and variants of bearings, to meet a variety of mechanical equipment and industrial applications, improve the adaptability and reliability of bearings.

4, JOJI bearings adopt strict quality control, from the selection of raw materials, production process, product testing, to after-sales service, all follow the international standards and customer requirements, to ensure the quality and reputation of bearings.

In a word, JOJI bearing is a kind of high-quality bearing products widely used in machinery manufacturing, engineering technology and industrial field, which has many kinds of types and features to meet different working conditions and needs, and to improve the efficiency and quality of machinery and equipment and industrial field.
