Product Description
Single-Row Tapered Roller Bearing Inner Diameter 60-900 mm
Double-row Tapered Roller Bearing Inner Diameter of 70-1120 mm
Four-row Tapered Roller Bearing Inner Diameter 139.7-780 mm
The tapered roller bearing is designed to have the taper surfaces of the Inner ring raceway, outer ring raceway and the rolling surface of the roller interest at 1 point in the central line of the bearing.
Products in the metric system as well as in the English system are available. For more information, please contact WGYS.
They suit for heavy load and impact load.
Single-row Tapered Roller Bearing
It can bear both radial load and one-way axial load.
The axial thrust load will occur when these bearings are bearing radial load, so 2 bearings should be used face to face or back to back(or in combination) .
According to different contact angles, they can be classified into 3 patterns: small taper angle, medium taper angle and big taper angle.
Double-row Tapered Roller Bearing
They can be divided into 2 kinds: TDO and TDI.
The former 1 has a outer ring with a double raceway and a inner ring with 2 single raceways while the latter 1 has a outer ring with 2 single raceways and a inner ring with a double raceway. Both can bear radial load and two-way axial load.
The sizes of Inner ring and out ring should be coped in advance to ensure the required internal clearance after installation.
Four-row Tapered Roller Bearing
They suit for low and medium speed rolling mills.
After investigation into the internal clearance in advance, they are easy to use.

What is the temperature tolerance for block bearings?
The temperature tolerance for block bearings can vary depending on factors such as the bearing design, materials used, lubrication, and specific application requirements. Block bearings are designed to operate within a certain temperature range to ensure optimal performance, lubrication effectiveness, and overall bearing life. Here are some key points regarding the temperature tolerance of block bearings:
1. Standard Temperature Range: In general, standard block bearings are designed to operate within a temperature range of -20°C to +120°C (-4°F to +248°F). This temperature range covers a wide range of industrial applications and is suitable for many common operating conditions. It is important to note that this is a general guideline, and specific bearing models or manufacturers may have their own temperature specifications.
2. High-Temperature Bearings: For applications that involve higher temperatures beyond the standard range, special high-temperature block bearings are available. These bearings are designed to withstand elevated temperatures and can operate reliably in conditions up to 200°C (392°F) or higher, depending on the specific design and materials used. High-temperature bearings typically incorporate heat-resistant materials and special lubricants to ensure stability and performance under extreme temperatures.
3. Low-Temperature Bearings: In applications where extremely low temperatures are encountered, such as in refrigeration or cryogenic environments, low-temperature block bearings may be required. These bearings are designed to withstand cold temperatures and maintain their performance even at temperatures as low as -50°C (-58°F) or lower. Special attention is given to the selection of materials and lubricants that can withstand low temperatures without compromising the bearing’s functionality.
4. Temperature Limitations: It’s crucial to consider the temperature limitations specified by the bearing manufacturer. Operating a block bearing outside of its recommended temperature range can lead to premature wear, lubrication breakdown, reduced load capacity, or even catastrophic failure. Factors such as the bearing’s materials, lubrication type, sealing, and cage design can all contribute to the temperature limitations of the bearing.
5. Lubrication Considerations: Proper lubrication is essential for maintaining the performance and temperature tolerance of block bearings. Lubricants have specific temperature ranges within which they can effectively operate. It’s important to select lubricants that are suitable for the anticipated operating temperatures to ensure proper lubrication and prevent issues like excessive friction, overheating, or lubricant degradation.
6. Consult Manufacturer Specifications: To determine the temperature tolerance of a specific block bearing, it is important to consult the manufacturer’s specifications, technical data sheets, or contact the manufacturer directly. They can provide detailed information about the recommended temperature range, limitations, and any special considerations for the specific bearing model.
Overall, the temperature tolerance of block bearings can vary depending on the specific design, materials, and lubrication used. It is crucial to select the appropriate bearing that matches the anticipated operating temperature to ensure reliable performance, minimize wear, and prolong the bearing’s service life.
How do I install a block bearing correctly?
Proper installation of a block bearing is crucial to ensure its optimal performance and longevity. Here’s a detailed explanation of the correct installation process for a block bearing:
- Prepare the Mounting Surface: Start by preparing the mounting surface where the block bearing will be installed. Ensure that the surface is clean, flat, and free from any debris or contaminants that could affect the bearing’s performance.
- Inspect the Bearing and Housing: Before installation, carefully inspect the block bearing and its housing for any signs of damage or defects. Check for any cracks, dents, or misalignment. Ensure that the bearing insert is clean and properly lubricated.
- Align the Mounting Holes: Align the mounting holes on the block bearing’s housing with the corresponding holes on the mounting surface. Use a level or straight edge to ensure proper alignment and prevent any misalignment that could lead to premature wear or failure.
- Secure the Bearing: Once the alignment is ensured, secure the block bearing onto the mounting surface using appropriate bolts or fasteners. Tighten the bolts gradually and evenly, following the manufacturer’s recommended torque specifications. Avoid over-tightening, as it can cause damage to the bearing or housing.
- Verify Shaft Alignment: After securing the block bearing, check the alignment of the shaft or rod that will be inserted into the bearing. Ensure that the shaft is properly aligned with the bearing’s inner race to prevent excessive load or stress on the bearing during operation.
- Apply Lubrication: Apply the recommended lubricant to the bearing insert according to the manufacturer’s guidelines. Proper lubrication is essential to minimize friction and wear, and it helps ensure smooth rotation and prolonged bearing life. Some block bearings have grease fittings or seals that allow for easy lubrication.
- Perform a Function Test: Once the block bearing is installed and lubricated, perform a function test to ensure smooth rotation and proper operation. Rotate the shaft or apply a load to the bearing and check for any abnormal noise, vibration, or resistance. If any issues are detected, double-check the installation and consult the manufacturer or technical support for further guidance.
It’s important to follow the manufacturer’s instructions and guidelines specific to the block bearing you are installing. These instructions may vary depending on the bearing size, type, and design. If in doubt, consult the manufacturer’s documentation, installation guides, or contact their technical support for assistance.
By following the correct installation procedures and ensuring proper alignment, securing, and lubrication, you can maximize the performance and service life of the block bearing.
