Sealed Spherical Plain Bearing GE30ES 2RS for Construction Machine

Description – GJP sealed spherical plain bearing for construction machine GE30ES 2RS (30x47x22mm)

GJP Bar Code Number: 6935329820944

GJP has been developing this sealed split spherical roller bearing for construction machine with high quality level, which requires this bearing to afford heavy loading, and slow rotation, this type of spherical plain bearing is made of two round races (inner race and outer race) and with phosplating and blackening treatment on the surface, because of it’s roundness of the bearing race, the bearing itself could rotate freely in any angle, the bearing has grease hole and one grease groove on bearing race, and there is one axial split in outer race, and has double seals on both side of bearing, GJP produce this bearing with radial internal clearance at 0.05 to 0.1mm and 62KN dynamic loading, 310KN static loading capacity.

Split spherical roller bearing for construction machine is a special structure of sliding bearing. Its structure is simpler than that of rolling bearings. It is mainly composed of an inner ring with an outer spherical surface and an outer ring with an inner spherical surface. It can withstand large loads. According to its different types and structures, it can withstand radial loads, shaft Radial load or combined radial and axial load. Joint bearings are generally used for low-speed swinging motion (ie angular motion). Since the sliding surface is spherical, it can also perform tilting motion (ie self-aligning motion) within a certain angle range. When the degree is large, it can still work normally.

Split spherical roller bearing for construction machine can withstand larger loads. According to its different types and structures, it can bear radial load, axial load or combined radial and axial load at the same time. Since the outer spherical surface of the inner ring is inlaid with composite materials, the bearing can produce self-lubrication during operation. It is generally used for low-speed swing motion and low-speed rotation. It can also be used for tilting motion within a certain angle range. When the misalignment between the support shaft and the shaft housing hole is large, it can still work normally. Self-lubricating spherical plain bearings are used in water conservancy, professional machinery and other industries.

Application of split spherical roller bearing

Spherical sealed plain bearings are widely used in engineering hydraulic cylinders, forging machine tools, engineering machinery, automation equipment, automotive shock absorbers, water conservancy machinery and other industries. Brief introduction and classification of spherical plain bearings The inner and outer rings of the contact surface are composed. Depending on its structure and type, it can bear radial load, axial load, or combined radial and axial loads at the same time. Because the spherical sliding contact area of ​​the spherical plain bearing is large, the inclination angle is large, and because most of the split spherical roller bearings adopt special processing methods, such as surface phosphating, galvanizing, chrome plating or outer sliding surface lining, padding, spraying, etc. Therefore, it has a large load capacity and impact resistance, and has the characteristics of corrosion resistance, wear resistance, self-alignment, good lubrication or self-lubricating without lubrication and dirt pollution, and can work normally even if the installation is misplaced. Therefore, spherical plain bearings are widely used for low-speed oscillating motion, tilting motion and rotational motion.

Features of split spherical roller bearing

The main features of split spherical roller bearings are:

1. Split design: Allows for easy installation and maintenance without disturbing the shaft or housing.
2. High load capacity: The roller design and large cross-section area provide high radial and axial load capacity.
3. Versatility: Available in a wide range of sizes and configurations for various industrial applications.
4. Improved reliability: The split design reduces the risk of bearing failure and increases overall reliability.
5. Cost-effective: The split design results in lower costs for manufacturing, transportation, and maintenance.
6. Self-aligning capability: The spherical roller design allows for misalignment in the shaft and housing, improving overall performance.
7. Robust construction: Split spherical roller bearings are built for durability and have a high resistance to impact and shock loads.

How to choose the right split spherical roller bearing

When choosing a split spherical roller bearing, there are several factors to consider:

1. Load: The bearing must be able to handle the radial and axial loads that the application will impose on it.

2. Speed: The bearing must be able to handle the rotational speed of the shaft.

3. Temperature: The bearing must be able to operate in the temperature range of the application.

4. Alignment: The bearing must be able to accommodate any misalignment that may occur in the application.

5. Size and space: The bearing must fit in the space available and be the appropriate size for the application.

6. Environment: The bearing must be able to withstand any harsh environmental conditions, such as dust, moisture, or corrosive materials, that may be present in the application.

7. Vibration: The bearing must be able to handle the vibration that may occur in the application.

8. Price and availability: The bearing should be cost-effective and readily available.

After considering all these factors, you should consult with a bearing supplier to ensure you are choosing the right bearing for your specific application.
