DKFL 5305 2RS C3 P5 Angular Contact Ball Bearin
The DKFL 5305 2RS C3 P5 is a double row angular contact ball bearing, with a design equivalent to the 3305 configuration. Its construction functions similarly to two single-row angular contact bearings arranged back-to-back. This enables it to support heavy radial loads as well as axial loads in both directions, while providing high moment rigidity in the assembly.

Product Detail
Double Row Angular Contact Ball Bearing DKFL 5305 2RS C3 P5 25 × 62 × 25.4 mm | Double Rubber Seals (2RS) | C3 Clearance & P5 Precision
The DKFL 5305 2RS C3 P5 double row angular contact ball bearing is designed to accommodate combined radial and axial loads in both directions. Equipped with rubber seals, C3 internal clearance, and P5 precision, it is an engineered solution for sensitive, high-precision industrial equipment, supplied by Kamyar Gostar Iranian Co. (KGICO).
Technical Overview of the DKFL 5305 2RS C3 P5 Angular Contact Bearing
The DKFL 5305 2RS C3 P5 is a double row angular contact ball bearing, with a design equivalent to the 3305 configuration. Its construction functions similarly to two single-row angular contact bearings arranged back-to-back. This enables it to support heavy radial loads as well as axial loads in both directions, while providing high moment rigidity in the assembly.
The 2RS suffix indicates rubber seals on both sides. These help retain the factory-applied grease and protect the bearing against dust and moisture. The C3 internal clearance provides additional room for thermal expansion under suitable operating conditions, while the P5 precision class indicates tighter dimensional and rotational tolerances than the normal class.
Designation & Structural Analysis (5305 2RS C3 P5)
Basic designation "5305": Identifies a wide double row angular contact ball bearing with a 25 mm bore (the 05 bore code corresponds to 25 mm).
Suffix "2RS": Indicates rubber seals on both sides, helping protect the bearing from environmental contaminants and retain its grease.
Suffix "C3": Specifies greater-than-normal internal radial clearance, which may be suitable for certain thermal expansion conditions or tight shaft fits.
Precision class "P5": Indicates ISO Class 5 dimensional and rotational precision, which is tighter than normal P0 tolerances and may suit applications requiring increased precision.
Supply & support: Supplied by Kamyar Gostar Iranian Co. (KGICO), with product authenticity and quality support.

Key Features & Advantages of the DKFL 5305
Bidirectional Combined Load Capacity
Designed to accommodate radial and axial loads in both directions, subject to the application and manufacturer’s ratings.
High Precision Class (P5)
Tighter dimensional and rotational tolerances can help support accurate, stable operation in precision applications.
C3 Internal Clearance
Provides greater-than-normal internal clearance, which may help accommodate operating temperature changes and certain fits.
Rubber Seals (2RS)
Seals on both sides help retain the factory-applied grease and protect against common contaminants. Relubrication requirements depend on the bearing design and operating conditions.
Double Row Construction
Provides a compact bearing arrangement for applications requiring support for combined radial and axial loads.
DKFL Brand
A precision bearing option for industrial equipment, supplied with technical support from KGICO.
Common Industrial Applications
- Industrial Pumps & Compressors: Supporting shafts and accommodating combined loads where the bearing arrangement is suitable.
- Light- and Medium-Duty Gearboxes: Supporting rotating components subject to radial and axial forces.
- Machine Tools & Precision Equipment: Suitable for selected shafts and rotating assemblies requiring controlled precision.
- Special-Purpose Electric Motors: Used in applications where bearing arrangement, load, speed, and fit requirements are compatible.
- Packaging & Printing Equipment: Supporting rotating assemblies where smooth operation and accurate fits are required.
Installation, Maintenance & Engineering Recommendations
Because this is a precision bearing, apply mounting force evenly to the ring with the interference fit. Do not transmit installation force through the rolling elements, and never strike the seals directly. Use suitable mounting tools and follow the bearing manufacturer’s instructions.
The 2RS seals help retain grease and protect the bearing. Avoid damaging the seal lips during handling or installation, and avoid exposure to incompatible solvents or excessive heat.
Check Alignment and Operating Conditions
Angular contact bearings can be sensitive to misalignment. Before commissioning, check shaft and housing alignment, fits, applied loads, and operating speed against the manufacturer’s specifications. C3 clearance and P5 precision should be verified against the requirements of the complete bearing arrangement.
Frequently Asked Questions (FAQ)
1. How does the 5305 differ from a 6205 deep groove ball bearing?
The 5305 is a double row angular contact ball bearing designed to support combined radial and axial loads. A 6205 is a single-row deep groove ball bearing with a different internal design and load-carrying characteristics. Check the manufacturer’s catalogue when comparing ratings and dimensions.
2. What does the P5 suffix mean?
P5 denotes an ISO Class 5 precision tolerance class, tighter than the normal tolerance class. The suitability of P5 depends on the precision and operating requirements of the application.
3. Does this bearing require relubrication?
The 2RS seals help retain the factory-applied grease, but whether relubrication is possible or required depends on the specific bearing design and operating conditions. Follow the manufacturer’s maintenance guidance.
