SL Double Row Full Complement Cylindrical Roller Bearings

SL double row full complement cylindrical roller bearings are a type of rolling-element bearing that have two rows of cylindrical rollers with no cage, allowing for maximum roller filling. This design provides high radial load-carrying capacity and enables the bearing to operate at high speeds while reducing friction. SL bearings are commonly used in heavy-duty applications such as construction equipment, mining machinery, and wind turbines. Their unique design also allows for easy installation and maintenance.

Advantages

SL double row full complement cylindrical roller bearings have the following advantages:

1. High load carrying capacity: Due to their high roller filling ratio, SL bearings can withstand higher radial loads.

2. High rigidity: Since there is no cage inside the bearing, SL bearings have higher rigidity.

3. Suitable for higher speeds: Compared to other types of cylindrical roller bearings, SL bearings have less friction due to the absence of a cage, making them suitable for higher rotating speeds.

4. Good self-lubricating performance: The high roller filling ratio inside the bearing provides good self-lubricating performance, reducing friction and wear.

5. Easy to install and maintain: The simple structure of SL bearings without a cage makes them easy to install and maintain.

In summary, SL double row full complement cylindrical roller bearings are high-load carrying, high-rigidity, suitable for high-speed, good self-lubricating performance, and easy-to-install and maintain rolling bearings.
