Deep Groove Ball Bearings SKF 6209

The SKF 6209 deep groove ball bearing, with a 45 mm bore and an 85 mm outer diameter, offers a tried-and-tested design for predominantly radial loads.

The 6209 deep groove ball bearing is a versatile, single-row rolling bearing in an open design. With key dimensions of 45 mm inner diameter, 85 mm outer diameter and 19 mm width, this radial ball bearing complies with standardised dimensions. Manufactured from standard roller bearing steel (100Cr6), the component withstands continuous mechanical stresses in industrial and trade applications. SKF’s Explorer design is engineered for smooth running, low friction and an operating temperature range of –20 to +120 degrees.

What is the 6209 deep groove ball bearing suitable for in machinery and plant?

The 6209 deep groove ball bearing primarily accommodates high radial forces as well as moderate axial forces in both directions. Installation is particularly recommended in enclosed housings with an existing lubrication system, as the open design does not feature integrated sealing protection. The dimensionally stable sheet steel cage guides the rolling elements with minimal vibration and is designed to withstand the dynamic loads encountered during continuous industrial operation.

What are the characteristics of the open design with standard bearing clearance?

The open design without sealing washers allows direct access of lubricant to the balls and raceways via an oil or grease supply within the housing. This ensures the bearing remains easily accessible for visual inspections and relubrication. With standard radial bearing clearance (standard), the bearing provides the appropriate clearance between the rolling elements and raceways at standard operating temperatures and with standard fits. Combined with tolerance class P0 (ABEC 1), this provides you with a precise guidance element for classic industrial applications.
