MGK 61802 2RS 15x24x5 mm Deep Groove Ball Bearing

1. Technical Specifications – MGK 61802 2RS

Technical verification: The 15x24x5 mm dimensions, deep groove ball bearing construction and double-sided sealing correspond to the 61802 2RS designation. Load ratings and operating speeds published for bearings from other manufacturers must not automatically be assigned to the MGK version.

2. Construction of the MGK 61802 2RS Bearing

The bearing consists of an inner ring, outer ring, balls, cage and two seals.

Both rings contain deep raceway grooves that guide the rolling elements and allow the bearing to accommodate radial and limited axial loads.

Inner Ring

The inner ring has a nominal bore diameter of 15 mm.

It is designed for installation on a shaft using an appropriate fit.

Outer Ring

The nominal outside diameter is 24 mm.

The outer ring is installed in the housing bore or another suitable supporting component.

Balls and Cage

The balls transmit loads between the inner and outer raceways.

The cage maintains the spacing between the rolling elements and reduces direct contact between adjacent balls.

The exact cage design and material require confirmation for the MGK version.

3. MGK 61802 2RS Designation Explained

61802 – Bearing Designation

Identifies a single-row, thin-section deep groove ball bearing with nominal dimensions of 15x24x5 mm.

618 – Dimensional Series

The 618 series includes bearings with a relatively small radial cross-section.

02 – Bore Code

In this designation, the bore code 02 corresponds to a nominal inside diameter of 15 mm.

2RS – Double-Sided Sealing

Indicates the presence of two elastomer seals, one on each side of the bearing.

The exact sealing lip geometry and contact characteristics require confirmation in MGK technical documentation.

MGK – Brand

Identifies the brand under which the bearing is supplied.

4. Thin-Section Design – Series 618

Bearings in the 618 series are characterised by a small radial cross-section.

For MGK 61802 2RS:

• Bore diameter: 15 mm.

• Outside diameter: 24 mm.

• Width: 5 mm.

• Difference between outside and inside diameters: 9 mm.

• Nominal radial cross-sectional height: 4.5 mm.

These dimensions allow the bearing to be used in compact rotating assemblies where installation space is limited.

However, thin-section bearings require particular attention to housing rigidity, loading conditions and mounting accuracy.

5. 2RS Seals – Function and Characteristics

The MGK 61802 2RS bearing features elastomer seals on both sides.

Their primary functions include:

• Limiting the ingress of dust and contaminants.

• Reducing lubricant leakage.

• Protecting the internal bearing components.

• Reducing the risk of contamination-related raceway and rolling element damage.

2RS vs 2Z

The two designs should not automatically be considered equivalent in terms of friction, sealing performance or permissible operating speed.

6. Radial and Axial Load Capacity

Radial Loads

Deep groove ball bearings are designed primarily to accommodate loads acting perpendicular to the shaft axis.

Axial Loads

The deep raceway geometry also allows limited axial loads to be accommodated in both directions.

Permissible axial loading depends on the bearing's internal geometry, clearance, operating speed and other service conditions.

Combined Loads

The bearing can operate under simultaneous radial and axial loading.

Selection requires calculation of the equivalent bearing load and verification of the expected fatigue life.

Without confirmed MGK load ratings, final engineering calculations should not rely on values published for other manufacturers.

7. Load Ratings and Fatigue Life

The basic dynamic load rating, C, is used to calculate nominal rolling bearing fatigue life.

The basic static load rating, C0, is used to evaluate bearing performance under static loading or very low rotational speeds.

For the exact MGK 61802 2RS designation, these values require confirmation.

Load ratings published by SKF, FAG, NSK, EZO or other manufacturers should not automatically be applied to this MGK bearing, even when nominal dimensions are identical.

8. Operating Speed

The permissible operating speed depends on:

• Seal construction.

• Lubricant type.

• Operating temperature.

• Applied loads.

• Internal clearance.

• Mounting fits and accuracy.

A 2RS bearing may have different speed limitations from an equivalent open bearing or a version fitted with 2Z shields.

The limiting speed of MGK 61802 2RS must be confirmed using the relevant product documentation.

9. Lubrication and Maintenance

Deep groove ball bearings fitted with 2RS seals are generally supplied with grease inside the bearing.

However, the exact grease type and quantity used in MGK 61802 2RS have not been confirmed.

Before using the bearing at elevated temperatures, high rotational speeds or in chemically demanding environments, the lubricant specification should be verified.

Seals should not be removed, and additional grease should not be introduced without an appropriate technical procedure.

10. Internal Clearance and Precision

Radial internal clearance affects bearing behaviour after mounting.

Common rolling bearing clearance classes include:

• CN – normal internal clearance.

• C3 – greater than normal clearance.

• C2 – less than normal clearance.

The absence of an additional clearance suffix in the product designation is not sufficient to confirm the exact clearance class of the MGK bearing.

The bearing precision class also requires manufacturer confirmation.

11. Mounting the 15x24x5 mm Bearing

Before installation, verify the shaft and housing dimensions.

Shaft Fit

The inner ring has a nominal bore diameter of 15 mm.

The appropriate shaft fit depends on the direction and magnitude of the applied loads.

Housing Fit

The outer ring is intended for a housing bore with a nominal diameter of 24 mm.

The required tolerance depends on the loading conditions and bearing arrangement.

Mounting Force

Mounting force must not be transmitted through the rolling elements.

The force should be applied directly to the ring being installed with an interference fit.

Incorrect mounting can cause permanent damage to the raceways.

12. MGK 61802 2RS vs 6802 2RS

The designations 61802 and 6802 are used for the same basic dimensional size of deep groove ball bearing.

Identical nominal dimensions and the same general bearing type do not guarantee identical load ratings, operating speeds, internal clearance, precision or sealing materials.

Before selecting a replacement, the technical specifications of both bearings must be compared.

13. Comparison with Other Bearing Series

This comparison describes general construction differences between bearing series.

Bearings with different outside dimensions are not direct dimensional replacements.

14. Industrial Applications

Deep groove ball bearings from the 618 series may be used in mechanical assemblies requiring compact installation dimensions.

General application categories include:

• Small rotating mechanisms.

• Shaft support assemblies.

• Compact gear mechanisms.

• Precision mechanical assemblies.

• Automation equipment.

• Manufacturing machinery components.

• Designs with restricted mounting space.

These are general applications of the 618 bearing series and do not establish that the exact MGK 61802 2RS is approved for a particular machine or device.

15. Bearing Selection and Pre-Installation Checks
