SW 6208-2Z/C3THD Deep Groove Ball Bearing | 40x80x18mm | Heavy Duty | High Temperature C3 Clearance
The SW 6208-2Z/C3THD is a high-performance single-row deep groove ball bearing engineered for demanding industrial environments. Featuring a standard dimension of 40x80x18 mm, this bearing is equipped with two low-friction non-contact metal shields (2Z) that effectively retain the specialized internal lubricant while protecting against dust ingress. The defining feature is the internal radial clearance classification of C3, which is greater than normal and essential for applications experiencing significant thermal expansion or high internal loads, such as electric motors, heavy-duty gearboxes, and high-speed pumps. The specialized SW THD suffix denotes a robust cage design and a proprietary High-Temperature/High-Density grease formulation optimized for extended operational life under severe duty cycles.
Designed as a direct replacement and performance upgrade over standard 6208 components, the SW 6208-2Z/C3THD ensures maximum reliability and reduced maintenance intervals. Its optimized geometry handles both radial and axial loads efficiently, providing stable operation even at high operational speeds (up to 11,000 RPM limit). The combination of the C3 clearance and the advanced THD grease makes this bearing exceptionally suited for critical infrastructure where uptime is paramount, delivering superior heat dissipation and vibration mitigation compared to standard or off-the-shelf bearings. This product is key to maximizing efficiency in rotating machinery.
