FAQ

What does the '2Z' suffix mean on the SKF 635-2Z bearing?
The '2Z' (or 'ZZ') suffix indicates that the bearing is fitted with two metal shields, one on each side. These shields protect the bearing's internal components from larger contaminants without making contact with the inner ring, resulting in low friction and suitability for high-speed applications.

Is this SKF Explorer bearing interchangeable with a standard 635-2Z bearing?
Yes, it is dimensionally interchangeable with any standard 635-2Z bearing (5x19x6mm). The 'Explorer' designation signifies a higher performance class from SKF, featuring optimized internal geometry, improved steel purity, and a unique heat treatment process. This typically results in a longer service life and higher dynamic load capacity compared to standard bearings.

What kind of lubrication is used in a sealed 635-2Z bearing?
SKF 635-2Z bearings are lubricated for life and filled with a high-quality grease at the factory. The specific grease type is chosen by SKF to provide excellent performance across a wide range of temperatures and operating conditions. The shields help retain this grease for the entire lifespan of the bearing.
