SKF 6207-2Z Metal Shielded Single Row Deep Groove Ball Bearing 35x72x17mm

The SKF 6207-2Z double-shielded deep groove ball bearing provides rotational support for industrial machinery fitted with a 35mm shaft and a 72mm bearing housing. Its 17mm width and single row deep groove design offer a practical balance of load capacity, compact dimensions and high-speed performance. The bearing accommodates predominantly radial loads together with axial forces in either direction, within its rated limits. SKF specifies a 27kN basic dynamic load rating and a 15.3kN basic static load rating, providing useful data for calculating bearing life and assessing operating loads. Its SKF Explorer performance classification reflects the manufacturer's optimised bearing design for friction, vibration and rotational performance.

The 2Z suffix identifies metal shields on both sides, rather than contact rubber seals. These shields help retain the factory-applied grease and restrict the entry of larger contaminants without rubbing against the inner ring in normal operation. This reduces sealing friction and makes the bearing particularly suitable for clean, higher-speed machinery, although it provides less protection against fine dust and moisture than a contact-sealed 2RS1 bearing. SKF lists a 20,000rpm reference speed and 10,000rpm limiting speed for the 6207-2Z. Actual operating speed must be assessed against load, lubrication and temperature. The bearing features normal (CN) radial internal clearance and a sheet metal cage. When replacing a bearing, confirm that the original equipment requires the 2Z shielded arrangement rather than a 2RS1 or C3 variant.
