61824 ABEG 120x150x16 mm - Deep Groove Ball Bearing

61824 ABEG 120x150x16 mm - Deep Groove Ball Bearing

61824 ABEG is a single-row deep groove ball bearing with dimensions of 120x150x16 mm. It belongs to the thin-section 618 dimensional series, characterized by a large bore combined with a relatively small radial cross-section. The deep groove design is primarily suitable for radial loads and can also accommodate axial loads in both directions within the limits of the bearing design.

Technical data - 61824 ABEG

What does 61824 mean?

The designation 61824 identifies a single-row deep groove ball bearing from the thin-section 618 dimensional series.

Its principal dimensions are:

• d = 120 mm

• D = 150 mm

• B = 16 mm

The bore code 24 corresponds to a nominal bore diameter of 120 mm.

61824 ABEG dimensions

The bearing measures:

120x150x16 mm

where:

• 120 mm - bore diameter

• 150 mm - outside diameter

• 16 mm - bearing width

With a 120 mm bore and an outside diameter of only 150 mm, the bearing has a particularly compact radial cross-section.

This is one of the key characteristics of the 618 series.

Thin-section 618 series

The 618 series is designed for bearing arrangements where a relatively large shaft diameter must be accommodated within restricted radial and axial installation space.

Compared with heavier deep groove ball bearing series with the same 120 mm bore, a 61824 has a substantially smaller cross-section.

This can help reduce:

• bearing arrangement outside diameter

• axial installation width

• radial installation space

• overall dimensions of the assembly

However, a 61824 should not be replaced by another 120 mm bore bearing without checking all principal dimensions and technical requirements.

61824 bearing construction

61824 ABEG is a single-row deep groove ball bearing.

Its basic construction consists of:

• inner ring

• outer ring

• one row of balls

• cage separating the rolling elements

• deep raceway grooves

Deep groove ball bearings are non-separable and are among the most versatile rolling bearing designs.

What loads can a 61824 bearing accommodate?

Deep groove ball bearings are primarily designed to accommodate radial loads.

Their raceway geometry also enables them to accommodate axial loads acting in both directions.

The actual permissible load depends on the specific bearing execution and manufacturer's technical data.

For this reason, dynamic or static load ratings from another manufacturer's 61824 should not automatically be assigned to the ABEG bearing.

Open bearing execution

The designation 61824 without an additional sealing or shielding suffix identifies the basic open execution.

In an open bearing, the rolling elements are not enclosed on both sides by integrated shields or seals.

Depending on the requirements of the bearing arrangement, different versions may use:

• open construction

• metal shields

• contact seals

• non-contact seals

• external sealing provided by the machine

The closure system can affect contamination protection, lubrication, friction and permissible operating conditions.

61824 vs 61824 2RS

The principal dimensions may remain:

120x150x16 mm

but the closure system differs.

61824

• open execution

• no integrated seals on both sides

61824 2RS

• sealed on both sides

• increased protection of the bearing interior

• different friction and speed characteristics

The closure type should therefore be selected according to the operating environment.

61824 vs 61824 ZZ

A ZZ version uses metal shields on both sides.

Therefore:

61824 - open bearing

61824 ZZ - bearing with metal shields on both sides

The closure suffix should not be ignored when selecting a replacement.

61824 vs 16024

The designations 61824 and 16024 may appear similar, but they belong to different dimensional series.

They should not be treated as interchangeable simply because the bore code 24 corresponds to 120 mm.

When comparing bearings, check:

• bore diameter d

• outside diameter D

• width B

• dimensional series

• closure

• radial internal clearance

• precision class

• operating requirements

The same bore diameter does not mean the bearings have the same installation dimensions.

61824 vs 61924

61824 and 61924 belong to different thin-section deep groove ball bearing series.

Although both use the bore code 24, their outside dimensions should not be assumed to be identical.

Correct identification requires the complete bearing designation and all principal dimensions.

How to select a replacement for 61824 ABEG

When selecting an alternative bearing, verify the following.

Dimensions

The principal dimensions must be:

120x150x16 mm

Bearing type

Single-row deep groove ball bearing.

Execution

Open, when replacing a bearing identified simply as 61824 without an additional closure suffix.

Radial internal clearance

Do not automatically assume Normal, C3 or another clearance class unless confirmed by the complete bearing designation.

Precision class

The bearing precision should meet the requirements of the application.

Cage

If cage material or cage design is important for the application, it should be confirmed for the specific bearing.

Operating parameters

Required load capacity, rotational speed, temperature, lubrication and environmental conditions should be checked.

Matching dimensions of 120x150x16 mm alone do not guarantee complete interchangeability.

Typical applications of 618 series bearings

Thin-section deep groove ball bearings from the 618 series can be used where a large shaft diameter is required but the available radial installation space is restricted.

Typical application groups for this bearing type can include:

• industrial machinery

• rotating mechanisms

• compact drive systems

• production equipment

• machinery with restricted radial installation space

• assemblies requiring a large shaft diameter with a compact bearing outside diameter

These are general applications of the 618 bearing series and do not confirm compatibility of 61824 ABEG with a particular machine.

Mounting 61824 ABEG

Before installation, check:

• shaft cleanliness

• housing cleanliness

• condition of the bearing seats

• correct shaft and housing fits

• alignment of the bearing arrangement

When an interference fit is used, mounting force should be applied directly to the ring being fitted.

Mounting force should not be transmitted through the balls and raceways, as this can damage the bearing's working surfaces.

Because of the thin-section construction, correct fits, alignment and prevention of ring deformation are particularly important.
