GJP Double Row Tapered Roller Bearings LL582949/LL582910, which is a large size with 736.6MM Inner Diameter, 825.5MM for Outer Diameter, and with a total height of 114.3MM, this bearing is a double row cylindrical roller bearing, which contains two cups, two cones, two spacers in the middle (spacers are used for adjust the clearance also) and two steel cage, two sets of steel ball with 100MM diameter of balls, GJP produce this bearing with outer ring rotation eccentricity of 100um, C3 clearance, and has a 3000 hours of “LB10” Bearing Life under 500RPM according to SKF stardard, and could have a loading capacity with Cor 3500KN, Cr 1450KN.

GJP designs all of our Tapered Roller Bearing with good manufactured Gcr15 material, which has the metallographic structure from Grade 2 to 4 according to ISO stardard, with tapered angle race way on bearing race including cone and cup and normally they are split type, which Cone and Cup could be separated, and we designed all of our rollers with crowning machinery technology, so that we could reduce the stress of the contacting place between rollers and bearing race, and could enlarge the bearing life for all GJP products, normally there is a tapered angle for cup with 10-19 degree and if this data is bigger, the loading capacity is bigger for the whole bearing sets.

A double row cylindrical roller bearing is a type of roller bearing that consists of two rows of cylindrical rollers arranged in a 90-degree angle to each other. These bearings are typically used in applications where high radial loads and moderate axial loads are present, such as in heavy machinery, gearboxes, and wind turbines. They can also be used in applications where the shaft is misaligned or where the shaft has to be adjusted during operation. They are also able to withstand high vibration and shock loads. These bearings come in different designs like with full complement or with cage, depending on the application, the design of the bearing will affect the load capacity and speed rating.

Features of double row cylindrical roller bearing

1. Large radial bearing capacity, suitable for bearing heavy loads and impact loads.
2. The friction coefficient is small, suitable for high speed, and the limit speed is close to that of deep groove ball bearings.
3. The inner ring or outer ring can be separated for easy installation and removal.

Installation of double row cylindrical roller bearing

The installation of a double row cylindrical roller bearing typically involves the following steps:

1. Cleaning: Clean the shaft and housing to remove any dirt, rust, or other contaminants.
2. Inspection: Inspect the shaft and housing for any damage, such as pitting or cracks, and replace if necessary.
3. Lubrication: Apply a suitable lubricant to the bearing and shaft to reduce friction and ensure proper operation.
4. Heating: If necessary, heat the bearing to expand it and make it easier to install.
5. Assembly: Place the bearing on the shaft or in the housing and align it correctly.
6. Tightening: Use an appropriate tool, such as a hydraulic press, to tighten the bearing into place.
7. Testing: After installation, test the bearing to ensure it operates correctly and there is no excessive play or binding.
8. Note: It’s important to follow the manufacturer’s instructions for installation to ensure proper fit, function, and longevity of the bearing.

Precautions when using double row cylindrical roller bearing

When using double row cylindrical roller bearings, it’s important to take the following precautions:

1. Proper installation: The bearing must be installed correctly and tightened to the correct torque. Improper installation can cause damage to the bearing and affect its performance.
2. Lubrication: The bearing must be lubricated with the appropriate lubricant, and the lubricant level should be checked and maintained regularly.
3. Cleanliness: The bearing and surrounding area must be kept clean to prevent contamination, which can cause damage to the bearing and affect its performance.
4. Overloading: The bearing must not be overloaded, as this can cause damage to the bearing and affect its performance.
5. Temperature: The bearing must not be exposed to temperatures outside of its operating range, as this can cause damage to the bearing and affect its performance.
6. Speed: The bearing must not be operated at speeds above its rated speed, as this can cause damage to the bearing and affect its performance.
7. Vibration: The bearing must not be exposed to excessive vibration, as this can cause damage to the bearing and affect its performance.
8. Alignment: The shaft and housing must be aligned correctly to prevent misalignment, which can cause damage to the bearing and affect its performance.
9. Maintenance: Regular inspections and maintenance should be performed to ensure the bearing is in good working condition and to identify and address any issues.

By following these precautions, you can help ensure that your double row cylindrical roller bearing operates correctly and has a long service life.
