Deep Groove Ball Bearings FAG 6309 -RSR
The FAG 6309-RSR deep-groove ball bearing combines dimensions of 45 × 100 × 25 mm with a single-sided RSR seal for protected bearing installations in continuous operation.
The 6309-RSR deep groove ball bearing is a single-row rolling bearing designed for combined radial and axial loads. FAG manufactures this model from standard roller bearing steel (100Cr6) with a bore of 45 mm, an outside diameter of 100 mm and a width of 25 mm. The design complies with tolerance class P0/PN (ABEC 1) and has standard radial clearance. A robust sheet steel cage guides the rolling elements with minimal vibration.
In which applications is the 6309-RSR deep groove ball bearing used?
This bearing design is primarily suitable for industrial applications involving combined loads. The bearing accommodates radial loads and provides axial support for the shaft in both directions. With an operating temperature range of –30 to +100 degrees, the component is suitable for a wide range of operating conditions. The cylindrical outer surface, which has no flange or groove, allows for direct mounting in standard housing bores.
What is the function of the single-sided RSR seal?
The factory-fitted, single-sided seal protects the interior of the bearing against dirt particles and moisture. At the same time, the opposite side remains open. This design is recommended when the component is supplied with lubricant from one side, but the outer side needs to be sealed against environmental influences. During assembly, the sealing lip is aligned towards the side at risk of contamination.
What are the dimensions of the 6309-RSR deep-groove ball bearing?
The bearing has an internal diameter of 45 mm, an external diameter of 100 mm and a width of 25 mm. These dimensions comply with the standardised 6309 series and allow for a precise fit in standardised housings and on corresponding shaft seats.
What does the suffix RSR mean in relation to this roller bearing?
The designation RSR stands for a single-sided sliding seal. The sealing lip contacts the inner ring and helps to keep out dirt and moisture, whilst the open rear side remains accessible for lubricant supply.
What is the bearing clearance of the component?
This model features standard radial bearing clearance (often referred to as CN). This defines the radial clearance of the rolling elements between the inner and outer rings when the bearing is unloaded. This standard clearance is entirely sufficient for typical fit selections and moderate operating temperatures without extreme thermal expansion.
What is the temperature range for which the 6309-RSR deep-groove ball bearing is designed?
The manufacturer specifies an permissible operating range of -30 to +100 degrees. Within these limits, both the standard roller bearing steel and the sealing material are designed for continuous use in mechanical engineering.
What material is the cage made of?
Inside, a guided sheet steel cage ensures that the rolling elements are evenly spaced. Sheet steel cages are characterised by their low weight, good strength and high resistance to lubricants, and have proven their worth in standard industrial applications.
Which tolerance class does the ball bearing correspond to?
The roller bearing is manufactured to tolerance class P0/PN, which corresponds to the ABEC 1 classification. This represents the industrial standard for dimensional, geometric and running accuracy, and is sufficient for the vast majority of applications in general mechanical and plant engineering.
