Sealing, C3 Clearance and Durability

Main Description

The 63005 2RS C3 TIMKEN 25x47x16 is a precision deep groove ball bearing designed for reliable operation in demanding industrial applications. This bearing combines a proven single-row ball bearing design with 2RS sealing and increased C3 internal clearance, making it suitable for higher speeds, elevated temperatures, and continuous-duty operation.

The 2RS seals on both sides effectively protect the bearing against dust, moisture, and industrial contaminants while retaining lubrication inside the bearing. This sealed configuration reduces maintenance requirements and supports long service life, even in challenging operating environments. The C3 clearance provides additional internal space to compensate for thermal expansion and shaft fit effects, ensuring stable performance where standard clearance may be insufficient.

With dimensions of 25x47x16 mm, this ball bearing is capable of carrying radial loads as well as moderate axial loads in both directions. It is commonly used in industrial sealing and bearing units, electric motors, pumps, gearboxes, fans, conveyors, and assemblies installed in a rigid bearing housing. The bearing can operate as a standalone component or as part of a complete bearing unit, supporting smooth rotation and consistent alignment.

TIMKEN is recognized in the B2B sector for manufacturing bearings with repeatable quality and robust performance. The 63005 2RS C3 model is selected by maintenance teams and equipment manufacturers who require high durability, operational stability, and predictable behavior under variable load and temperature conditions. Its optimized internal geometry minimizes friction and vibration, contributing to efficient and reliable machine operation.

Designed for industrial use, this bearing supports reduced downtime, longer maintenance intervals, and dependable performance in both new installations and replacement applications.
