SKF BS2-2211-2RSK/VT143 Spherical Roller Bearing 55x100x31

Sealed Spherical Roller Bearing for Heavy-Duty Operation

High Durability and Contamination Protection

Industrial Applications and Bearing Units

Main Description:
The SKF BS2-2211-2RSK/VT143 is a double-row spherical roller bearing with dimensions 55x100x31 mm, engineered for demanding industrial environments. Its spherical roller design allows compensation for shaft misalignment and housing deflection, making it a reliable solution in heavy-duty machinery and dynamic operating conditions.

The 2RSK designation indicates double-sided sealing, effectively protecting the bearing against dust, moisture and contamination. This integrated sealing system significantly extends service life compared to open designs. The VT143 specification confirms factory filling with a high-quality grease optimized for specific load and temperature conditions, reducing maintenance requirements and improving operational reliability.

This spherical roller bearing is designed to carry high radial loads and moderate axial loads in both directions. Compared to a standard ball bearing, it provides superior performance under heavy loads and misalignment. Its high durability and robust internal construction ensure stable performance in gearboxes, industrial fans, conveyors, crushers and processing equipment.

SKF BS2-2211-2RSK/VT143 can be installed in a bearing housing or used as part of a bearing unit where long service intervals and operational safety are critical. The sealed and pre-lubricated configuration minimizes downtime and supports efficient maintenance planning in industrial facilities.

For maintenance engineers, procurement managers and industrial service providers, this bearing delivers dependable performance in applications where reliability and load capacity are essential.
