JP 12049A/10 NAF 120x170x27 mm - Tapered Roller Bearing

JP 12049A/10 NAF 120x170x27 mm - Tapered Roller Bearing

JP 12049A/10 NAF is a single-row tapered roller bearing set with dimensions 120x170x27 mm. The bearing consists of the inner ring with tapered rollers, designated JP12049A, and the separate outer ring, designated JP12010. Its tapered roller geometry is designed to accommodate combined radial and axial loads.

JP 12049A/10 NAF - Technical Data

Dimensions

The principal dimensions of JP 12049A/10 NAF are:

120x170x27 mm

• bore diameter d: 120 mm

• outside diameter D: 170 mm

• total bearing width T: 27 mm

• inner ring width B: 25 mm

• outer ring width C: 19.5 mm

These dimensions are important when identifying an existing bearing or selecting an equivalent.

JP12049A and JP12010 Bearing Set

The complete bearing consists of two matching components:

JP12049A - cone

and

JP12010 - cup

The cone assembly incorporates the inner ring, tapered rollers and cage, while JP12010 is the corresponding outer ring.

For complete bearing replacement, both components must correspond to the required bearing set.

Single-Row Tapered Roller Bearing Design

JP 12049A/10 is a single-row tapered roller bearing.

The raceways of the inner and outer rings and the tapered rolling elements are designed so that their geometry works together to transmit combined loads.

This bearing type is particularly suitable for applications where significant radial loading occurs together with axial loading.

Radial and Axial Load Capability

Unlike a conventional radial ball bearing, a tapered roller bearing is specifically designed for combined loading.

JP 12049A/10 can support:

• radial loads

• axial loads in one direction

• combined radial and axial loads

When axial forces must be supported in both directions, tapered roller bearings are commonly arranged in pairs or combined with another suitable locating bearing.

The exact bearing arrangement must correspond to the machine manufacturer's design.

Bearing Adjustment and Internal Clearance

A single-row tapered roller bearing does not use interchangeability rules identical to those of a standard deep groove ball bearing.

The operating clearance or preload depends on the complete bearing arrangement and installation.

Correct adjustment is important because excessive clearance or excessive preload can negatively affect:

• load distribution

• operating temperature

• running accuracy

• friction

• bearing service life

The bearing should therefore be installed and adjusted according to the requirements of the original machine or axle assembly.

Alternative Designations

JP 12049A/10 may be encountered under several designation formats:

• JP 12049A/10

• JP12049A/10

• JP12049A / JP12010

• JP12049A/JP12010

• JP 12049A / JP 12010

• JP12049/10

• JP 12049/10

• JP12049/JP12010

• JP12049A/12010

• JP 12049A/12010

• T4CB120

• T4CB 120

• 4T-T4CB120

• 12049/12010

• 515-911

• 515911

When searching for a replacement, the complete dimensions and bearing construction should always be checked in addition to the reference number.

Cross-Reference T4CB120

The JP12049A/JP12010 bearing set is also associated in bearing catalogues with the designation:

T4CB120

and, depending on manufacturer notation:

4T-T4CB120

These references are useful when searching industrial and agricultural bearing catalogues.

However, a cross-reference should always be verified against the complete dimensional and application requirements before replacement.

Application References

JP 12049A/10 is found in aftermarket catalogues for agricultural machinery, construction equipment and drivetrain applications.

Catalogue references associated with this bearing family include:

These numbers should be treated as identification and cross-reference information. Exact compatibility must be confirmed for the specific machine, axle or bearing position.

Agricultural and Construction Machinery Applications

The JP12049A/JP12010 bearing family appears in aftermarket catalogues in connection with selected machinery and components from manufacturers including:

• John Deere

• Fendt

• Renault

• SAME

• Carraro

It is also encountered in bearing applications for tractors, agricultural machinery, excavators and backhoe loaders.

This does not mean that JP 12049A/10 fits every machine from these manufacturers.

The original bearing number, OEM reference, dimensions and installation position should always be verified.

JP 12049A/10 vs JP 12049/10

Both JP 12049A/10 and JP 12049/10 appear in aftermarket bearing catalogues.

The complete supplied designation should therefore be retained when identifying existing stock.

For the NAF product, the bearing may be encountered as:

JP 12049/10 NAF

while the bearing family is also widely searchable as:

JP 12049A/10

The principal dimensions remain:

120x170x27 mm

Selection and Interchangeability

Before replacing JP 12049A/10 NAF, verify:

1. Bearing designation.

2. Cone designation JP12049A.

3. Cup designation JP12010.

4. Bore diameter 120 mm.

5. Outside diameter 170 mm.

6. Total width 27 mm.

7. Cone and cup dimensions.

8. Bearing arrangement.

9. Required operating clearance or preload.

10. Original equipment or machine reference.

Matching the dimensions alone does not automatically guarantee complete interchangeability.

Installation

Before installing JP 12049A/10 NAF:

• clean the shaft and housing seats

• inspect the mating surfaces

• check shaft and housing tolerances

• keep the bearing components free from contamination

• use appropriate bearing mounting tools

• apply installation force to the ring being fitted

• ensure correct seating of the cup

• verify the required bearing adjustment

• use the lubrication specified for the application

Do not transmit mounting forces through the tapered rollers.

After installation, the complete bearing arrangement should rotate correctly without inappropriate play, excessive preload or abnormal resistance.
