TIMKEN 26883 35 mm - Tapered Roller Bearing Cone

TIMKEN 26883 35 mm - Tapered Roller Bearing Cone

TIMKEN 26883 is a cone assembly for an inch-series single-row tapered roller bearing. The 26883 designation identifies the inner ring assembly with tapered rollers and cage, not a complete bearing. The cone has a 35.000 mm bore diameter. To form a complete tapered roller bearing, TIMKEN 26883 must be combined with the appropriate outer race, referred to as a cup.

Technical data - TIMKEN 26883

What does TIMKEN 26883 mean?

26883 is the TIMKEN catalogue designation for a cone assembly used in tapered roller bearings.

A conventional single-row tapered roller bearing consists of two separable components:

• cone - inner ring, tapered rollers and cage assembly

• cup - outer ring

TIMKEN 26883 is the cone component.

For this reason, the designation 26883 alone should not be presented as a complete tapered roller bearing.

TIMKEN 26883 bore diameter

The principal dimension identifying the 26883 cone is:

d - 35.000 mm

This is the bore diameter of the inner ring.

The corresponding nominal inch dimension is:

1.3780 in

A single outside diameter D or overall bearing width T should not be assigned to TIMKEN 26883 alone because these dimensions depend on the cup used to form the complete bearing assembly.

TIMKEN 26883 cone construction

TIMKEN 26883 is the inner assembly of a tapered roller bearing.

The cone assembly consists of:

• inner ring

• inner raceway

• tapered rollers

• cage

When combined with the correct outer cup, these components form a complete single-row tapered roller bearing.

The tapered geometry of the raceways and rolling elements allows tapered roller bearings to accommodate combined radial and axial loads.

TIMKEN 26883 and 26820

One TIMKEN bearing combination using the 26883 cone is:

TIMKEN 26883/26820

This assembly consists of:

• Cone: 26883

• Cup: 26820

• d - bore diameter: 35.000 mm

• D - outside diameter: 80.167 mm

• T - overall width: 25.400 mm

The complete TIMKEN 26883/26820 bearing therefore has dimensions:

35x80.167x25.400 mm

It is important to distinguish between:

26883 - cone

26820 - cup

26883/26820 - complete tapered roller bearing assembly

Does TIMKEN 26883 fit only the 26820 cup?

No.

The TIMKEN 26883 cone can be catalogued in different cone/cup combinations. Examples include:

• 26883/26820

• 26883/26822

• 26883/26822A

• 26883/26823

• 26883/26824

Different cups can produce different outside dimensions and overall widths for the complete bearing assembly.

For this reason, the 26883 designation alone does not define one complete d x D x T bearing size.

TIMKEN 26883/26822

For the TIMKEN 26883/26822 combination:

• d: 35.000 mm

• D: 79.375 mm

• T: 23.812 mm

Complete bearing dimensions:

35x79.375x23.812 mm

TIMKEN 26883/26824

For the TIMKEN 26883/26824 combination:

• d: 35.000 mm

• D: 80.000 mm

• T: 23.813 mm

Complete bearing dimensions:

35x80x23.813 mm

These different combinations demonstrate why TIMKEN 26883 should not be assigned a single outside diameter or overall width when sold as an individual cone.

TIMKEN 26883 vs complete tapered roller bearing

If a removed component is marked TIMKEN 26883, the marking identifies the cone assembly.

If a complete bearing is required, the cup designation must also be determined.

For example:

26883 + 26820 = 26883/26820

while:

26883 + 26822 = 26883/26822

These are different bearing assemblies with different external dimensions.

How to select a cup for TIMKEN 26883

The safest method is to identify the designation marked on the original outer race.

Before ordering a complete bearing, verify:

• cone designation 26883

• cup designation

• shaft diameter

• housing bore

• overall bearing width

• operating requirements of the application

A cup should not be selected solely because it belongs to the same numerical bearing series.

Alternative designations and search references

TIMKEN 26883 may also be searched as:

• TIMKEN 26883

• 26883 TIMKEN

• Timken 26883 cone

• 26883/26820 TIMKEN

Designations containing a slash refer to specific cone/cup bearing assemblies, not to the individual 26883 cone.

Installation

During installation, all bearing components and mating surfaces should be kept clean. The cone should be mounted using appropriate tools, and installation force should not be transmitted through the tapered rollers.

If an existing cup is to be reused, inspect its raceway for wear, pitting, corrosion or other damage before installing the new cone.

The compatibility of the cone and cup should always be verified before assembly.

FAQ

What is TIMKEN 26883?

TIMKEN 26883 is a cone assembly for a tapered roller bearing. It consists of the inner ring, tapered rollers and cage.

Is TIMKEN 26883 a complete bearing?

No. TIMKEN 26883 is the cone only. A compatible cup is required to form a complete tapered roller bearing.

What is the bore diameter of TIMKEN 26883?

The bore diameter is 35.000 mm, corresponding to a nominal inch dimension of 1.3780 in.

Which cup fits TIMKEN 26883?

TIMKEN 26883 can be used in different catalogued cone/cup combinations, including assemblies with 26820, 26822, 26822A, 26823 and 26824 cups. The correct cup must be selected for the required bearing configuration.

What are the dimensions of TIMKEN 26883/26820?

The complete TIMKEN 26883/26820 bearing has dimensions of 35x80.167x25.400 mm.

What are the dimensions of TIMKEN 26883/26822?
