Deep Groove Ball Bearings SKF 6210 -2Z/C3

The SKF 6210 -2Z/C3 single-row deep groove ball bearing, measuring 50x90x20 mm and featuring cover plates on both sides and a C3 clearance, provides mechanical protection against dirt particles.

The SKF 6210 -2Z/C3 deep groove ball bearing is a versatile radial ball bearing for industrial drives and mechanical designs. Fitted with an inner and outer ring made of standard roller bearing steel (100Cr6), this single-row bearing guides the rolling elements within a sturdy sheet steel cage. The design accommodates both radial forces and axial forces acting in both directions. Thanks to the non-contact gap seal, the lubricant remains within the bearing chamber, whilst friction losses are minimal compared to those caused by sliding seal lips.

What is the 6210-2Z/C3 deep-groove ball bearing suitable for?

This rolling bearing is suitable for rotating shafts in industrial drive systems and mechanical structures subject to moderate dust exposure. Designers prefer to use the combination of non-contact cover plates and increased operating clearance in applications where higher speeds occur and frictional heat is generated. The metal shields repel coarse dirt particles and foreign matter. Furthermore, the cylindrical outer ring, which has no groove or flange, ensures easy installation in standardised housing bores.

What distinguishes the version with C3 bearing clearance and 2Z cover plates?

The suffix C3 denotes a slightly increased radial bearing clearance compared with the standard version. This increased radial clearance compensates for thermal expansion when the shaft heats up more than the housing during operation. It prevents stress build-up in the bearing when tight fits are selected for the shaft and housing. The designation 2Z refers to cover plates made of sheet steel, pressed in on both sides. This gap cover does not generate any additional frictional torque and supports operation within a temperature range of -20 to +120 degrees Celsius.
