Deep Groove Ball Bearings SKF 625 -2Z/C3

Compact SKF deep-groove ball bearing 625 -2Z/C3, measuring 5x16x5 mm, with sheet metal end plates on both sides and increased radial clearance for smooth-running small drives.

The SKF 625 -2Z/C3 deep groove ball bearing is a single-row miniature rolling bearing made from standard bearing steel (100Cr6) with a bore of 5 mm, an outer diameter of 16 mm and a width of 5 mm. The design primarily accommodates radial loads and guides shafts precisely in compact installations. Fitted with a robust sheet steel cage and metal shields on both sides, the unit resists ingress of foreign particles without incurring additional friction losses. This makes the bearing suitable for precision mechanical applications.

In which applications is the 625-2Z/C3 deep-groove ball bearing used?

This miniature deep-groove ball bearing is primarily used in small drives, precision mechanical devices and compact bearing arrangements. With dimensions of 5 × 16 × 5 mm, the component fits into housings with limited installation space. As the sheet metal cover plates operate without contact, the bearing causes virtually no torque loss at higher speeds. In clean to slightly dusty working environments, the covers shield the rolling elements from coarser dirt particles.

What does the designation -2Z/C3 mean in terms of design?

The suffixes denote key technical characteristics: the abbreviation 2Z stands for sheet steel cover plates pressed in on both sides, which reduce lubricant leakage and repel particles. The suffix C3 denotes a slightly increased radial bearing clearance compared with the standard version. This prevents the rolling elements from seizing up if temperature differences occur between the inner and outer rings during operation, or if tight fits reduce the clearance. The bearing is designed for a temperature range of -20 to +120 degrees.
