DKFL 62310 2RS C3 Deep Groove Ball Bearing
Deep groove ball bearings are the most widely used bearing type across various industries. The DKFL 62310 2RS C3 model, with its specific geometric profile, is designed to accommodate radial loads as well as axial loads in both directions. The 2RS suffix indicates rubber contact seals on both sides, which effectively prevent the ingress of dust, moisture, and foreign particles into the internal mechanism while retaining the factory-packed grease.

The DKFL 62310 2RS C3 deep groove ball bearing features advanced manufacturing technology, dual rubber seals, and specialized C3 clearance, making it an ideal choice for heavy industrial operations, contaminated environments, and high thermal conditions, distributed by Kamyar Gostar Iranian Co. (KGICO).
Technical Overview of DKFL 62310 2RS C3 Bearing
Deep groove ball bearings are the most widely used bearing type across various industries. The DKFL 62310 2RS C3 model, with its specific geometric profile, is designed to accommodate radial loads as well as axial loads in both directions. The 2RS suffix indicates rubber contact seals on both sides, which effectively prevent the ingress of dust, moisture, and foreign particles into the internal mechanism while retaining the factory-packed grease.
Furthermore, the C3 internal clearance provides greater internal freedom between the rolling elements and rings compared to normal clearance. This specialized feature allows the bearing to accommodate thermal expansions resulting from continuous operation or high rotational speeds without binding or increasing internal friction.
Designation & Structural Analysis (62310 2RS C3)
Series "62": Indicates standard deep groove ball bearings designed for moderate to high radial load capacities.
Size "310" (Special Dimension): Denotes a 50 mm bore diameter with reinforced cross-section dimensions within the dedicated 62300 series, offering higher load ratings than standard 6210 models.
Suffix "2RS": Equipped with synthetic rubber (NBR) contact seals reinforced with steel inserts on both sides for superior environmental protection.
C3 Clearance: Radial internal clearance greater than normal, ideal for applications with high temperature differentials between shaft and housing or high speeds.
DKFL Brand Quality: Manufactured from premium alloy steel, precise heat treatment, and strict quality control, supplied by Kamyar Gostar Iranian Co. (KGICO).

DKFL Brand Authenticity
Direct supply meeting international standards with full technical support from Kamyar Gostar Iranian Co. (KGICO).
Common Industrial Applications
- Heavy Electric Motors: Handling high temperatures and speeds in large ventilation and pump motors.
- Industrial Fans & Blowers: Stability against shaft thermal expansion caused by airflow and operating heat.
- Agricultural & Construction Machinery: Excellent resistance to dust, mud, and environmental shock loads.
- Cement, Steel & Mining Industries: Utilized in power transmission sections and belt conveyors.
- Industrial Gearboxes: Reliable performance on high-speed shafts under specified radial loads.
Installation Guidelines & Engineering Recommendations
Due to C3 internal clearance, a slight radial play in the cold state is normal. This clearance reaches its optimal operational level under operating heat and shaft expansion and should not be mistaken for excessive wear or damage.
Never use direct open flames or heat exceeding 110°C (230°F) to mount the bearing, as excessive heat will severely damage the 2RS rubber seals and internal grease. Use standard induction heaters instead.
Shaft and Housing Tolerances
It is recommended to machine the shaft with proper tolerance fits (such as k5 or j6) and the housing to standard tolerances to prevent stress concentrations and ring damage.
Frequently Asked Questions (FAQ)
1. What is the main difference between series 62310 and standard 6210?
The 62300 series features a greater width and cross-section compared to standard 6200 bearings, enabling it to handle heavier loads and harsher operating conditions.
2. Does the 2RS suffix require re-greasing?
No, these bearings are packed with high-quality grease at the factory and sealed with rubber contact seals, requiring no re-greasing under normal operating conditions.
3. Why is C3 clearance used in this model?
C3 clearance provides extra internal room for thermal expansion of components at high speeds or elevated operating temperatures, preventing bearing binding.
