genuine koyo 308/800R tapered roller bearing manufacture high-capacity load support for industrial machinery

Model Number：

308/800R

Single row tapered roller bearings

Single row tapered roller bearings are designed to accommodate combined radial and axial loads and provide low friction during operation. 

The inner ring, with rollers and cage, can be mounted separately from the outer ring. 

These separable and interchangeable components facilitate mounting, dismounting and maintenance. 

By mounting one single row tapered roller bearing against another and applying a preload, a rigid bearing application can be achieved.

High radial and axial load carrying capacity accommodate axial loads in one direction. 

It has Low friction and long service life, eparable and interchangeable components.

Installation Method and Usage Precautions of Tapered Roller Bearings: :                                                 

Tapered roller bearings are commonly used in various machinery and equipment for their ability to support high radial and axial loads. 

Proper installation and maintenance are crucial to ensure their performance and longevity. 

 

Installation Method: 

 

1.Clean the shaft and housing before installation to remove any dirt or debris that could affect the bearing's performance. 

2.Apply a thin layer of lubricant to the bearing surfaces to reduce friction during installation. 

3.Use a suitable tool, such as a press or a mounting sleeve, to apply force evenly on the inner ring while mounting the bearing onto the shaft. 

4.Ensure that the bearing is seated properly and securely on the shaft without any misalignment. 

5.Install the bearing housing carefully to avoid any damage to the bearing or the housing itself. 

6.Tighten the mounting bolts to the recommended torque values to secure the bearing in place. 

Usage Precautions: 

 

1.Regularly inspect the bearing for any signs of wear, damage, or contamination. Replace the bearing if any abnormality is detected. 

2.Monitor the operating temperature of the bearing to prevent overheating, which can lead to premature failure. 

3.Maintain the proper lubrication level and replenish the lubricant as needed to ensure smooth operation. 

4.Avoid overloading the bearing beyond its rated capacity to prevent excessive wear and potential failure. 

5.Protect the bearing from contaminants such as dust, dirt, and moisture, which can accelerate wear and reduce the bearing's lifespan. 

6.Follow the manufacturer's recommendations for maintenance intervals and procedures to prolong the bearing's service life. 

In conclusion, proper installation and regular maintenance are essential for ensuring the reliable performance of tapered roller bearings. 

By following the recommended installation method and usage precautions, you can maximize the bearing's efficiency and durability in your machinery and equipment.

Introduction about Tapered Roller Bearings                                                                                                                                               

The KOYO 308/800R is a single row tapered roller bearing designed to handle heavy loads and impact loads commonly found in industrial applications.

This bearing is known for its robust construction and high performance capabilities.

1. Specifications:

   The bearing has an inner diameter (d) of 800 mm and an outer diameter (D) of 1220 mm, with a width (B) of 270 mm
   

2. Load Ratings:

• Basic dynamic load rating (Cr) is 74000 kN, and the basic static load rating (C0r) is 143000 kN
  

• The fatigue load limit (Cu) is 7700 kN.

3. Limiting Speeds:

   The limiting speed with grease lubrication is 130 min-1, and with oil lubrication, it can reach up to 180 min-1
   

4. Mounting Dimensions:

   The minimum inner diameter (da) and maximum outer diameter (Da) are critical for proper fitting and installation
   

5. Design and Construction:

   Tapered roller bearings consist of an outer ring, an inner ring, rollers, and a cage.

   The raceway surfaces of the inner and outer rings and the rolling contact surface of the rollers are designed

   so that their respective apexes converge at a point on the bearing center line
