F-809030.05 Combined Bearing 79.9×140.2×52 mm for Industrial Air Compressor Assemblies
Contact Supplier
Product Highlights
- Combined bearing arrangement - Integrated shaft support: Combines different rolling-element functions within a compact compressor bearing assembly, subject to the confirmed original design.
- Angular contact ball bearing section - Axial positioning capability: Angular contact geometry can support axial loading while contributing to controlled shaft location.
- Cylindrical roller bearing section - High radial load capability: Roller contact geometry provides efficient support for substantial radial loads.
- Special compressor-specific construction - Application-focused replacement: Designed for a particular bearing arrangement rather than general-purpose industrial interchange.
- 79.9*140.2*52 mm catalog dimensions - Accurate identification: Helps distinguish this special reference from conventional 80*140 mm bearings.
- Compact integrated assembly - Efficient installation space: Multiple bearing functions may be accommodated within one defined mounting envelope.
- Application-specific internal geometry - Controlled operating performance: Correct internal arrangement is important for load distribution and shaft positioning.

Why Combined Bearings Matter in Compressor Assemblies
Compressor shaft support may require more than one bearing function.
A cylindrical roller bearing section is primarily suited to radial loading, while an angular contact ball bearing section can provide axial positioning capability.
Combining these functions may allow the bearing assembly to support the compressor shaft within a compact arrangement.
However, the actual load distribution depends on the original internal design, bearing arrangement, preload or clearance, lubrication and operating conditions.
