807813 CT 65x110x30,5 mm - Single Row Tapered Roller Bearing

807813 CT - Product Characteristics

The 807813 CT belongs to the family of single row tapered roller bearings designed for mechanical assemblies subjected to combined radial and axial loading.

Unlike cylindrical roller bearings, tapered roller bearings have conical raceways and tapered rolling elements. This geometry enables them to accommodate radial loads together with axial loads acting in one direction.

When axial shaft location is required in both directions, tapered roller bearings are commonly arranged in opposed pairs or used in another appropriately engineered bearing arrangement.

The separable design allows the outer ring to be installed independently from the inner ring assembly, which includes the tapered rollers and cage.

Correct adjustment of axial clearance or preload is particularly important for achieving the intended operating performance.

Technical Specifications - 807813 CT

What Does 807813 CT Mean?

The designation consists of a bearing reference number and a brand identifier.

807813 - the catalogue designation of a single row tapered roller bearing with nominal dimensions of 65x110x30,5 mm. The 807813 reference is also found in bearing catalogues associated with brands such as GPZ and URB.

CT - the brand identifier supplied for this product. Without manufacturer documentation, CT should not be interpreted as an internal clearance class, cage material or precision grade.

65x110x30,5 mm - the nominal bore diameter, outside diameter and overall assembled bearing width.

For tapered roller bearings, the overall width T must be distinguished from the individual widths of the inner and outer rings.

These dimensions are important when evaluating replacement bearings and mounting compatibility.

Construction and Operating Principle

The 807813 CT tapered roller bearing consists of four principal components:

• Inner ring: Contains the inner tapered raceway and provides the mounting surface for the shaft.

• Outer ring: Contains the outer tapered raceway and fits into the housing.

• Tapered rollers: Transmit combined radial and axial forces between the raceways.

• Cage: Maintains the relative positioning and spacing of the rolling elements.

The tapered geometry of the rolling elements and raceways enables the bearing to accommodate combined loading.

Under radial loading, the geometry also generates an axial force component that must be considered when designing the bearing arrangement.

A single row tapered roller bearing supports externally applied axial loads in one direction. Opposed bearing arrangements are therefore commonly used where axial location is required in both directions.

The bearing is separable, allowing the inner ring and roller assembly to be mounted independently of the outer ring.

As an open bearing, it requires an appropriate lubrication system and protection against external contamination.

807813 CT Compared with Other 807813 Bearing Variants

The 807813 designation is used in bearing catalogues by different manufacturers. However, matching reference numbers or nominal dimensions do not necessarily guarantee complete interchangeability.

Some catalogues list the 34513 URB bearing with an overall width of 29,5 mm rather than 30,5 mm.

This dimensional difference means that 34513 URB should not automatically be used as a replacement for 807813 CT.

The complete ring dimensions, internal geometry and mounting requirements must be verified before substitution.

Alternative Designations and Reference Formats

The bearing may be identified using the following designation formats:

• 807813 CT

• CT 807813

• CT tapered roller bearing 807813

• 807813 CT 65x110x30,5 mm

• Single row tapered roller bearing 807813

Other manufacturers may offer bearings under the 807813 reference. However, no direct replacement for the exact CT version should be assumed without technical confirmation.

Applications of 807813 CT

Bearings with the 807813 designation are found in aftermarket catalogues for vehicle running gear and mechanical assemblies.

Some commercial references associate 807813 CT with wheel hub applications in GAZ and ZIL vehicles. These listings should be treated as identification information rather than confirmation of compatibility with every model.

From a mechanical engineering perspective, single row tapered roller bearings are suitable for appropriately designed assemblies where combined radial and axial loads must be accommodated.

Typical applications for this bearing type include wheel hub arrangements, rotating shaft supports and mechanical transmission assemblies.

The exact application of 807813 CT must be verified using the equipment manufacturer's parts documentation and the original bearing reference.

Bearing Selection and Interchangeability

Before purchasing 807813 CT or selecting a replacement, verify the following:

1. Complete designation: 807813 CT.

2. Bore diameter: 65 mm.

3. Outside diameter: 110 mm.

4. Overall width: 30,5 mm.

5. Individual ring dimensions: Inner ring width, outer ring width and assembly geometry.

6. Axial adjustment: Required endplay or preload.

7. Load requirements: Magnitude and direction of radial and axial forces.

8. Operating conditions: Rotational speed, temperature, lubrication and contamination protection.

Matching the three principal dimensions does not automatically establish interchangeability.

Differences in contact angle, internal geometry, tolerances and load ratings can affect the operation of the complete bearing arrangement.

Installation and Operating Recommendations

Before installation, clean the shaft, housing bore and all mounting surfaces. Inspect them for wear, damage and dimensional accuracy.

When mounting the bearing, apply installation force only to the ring being fitted with an interference fit.

Never transmit installation force through the tapered rollers and raceways.

Because the bearing is separable, the outer ring and inner ring assembly must be installed correctly and kept free from contamination.

Correct adjustment of axial clearance or preload is essential.

Excessive preload can increase friction and operating temperature, while excessive clearance can reduce shaft positioning accuracy and affect bearing service life.

Use the lubricant and lubrication method specified for the mechanical assembly.

Store the bearing in its original protective packaging in a clean, dry environment until installation.

Frequently Asked Questions - FAQ

What are the dimensions of 807813 CT?

The bearing has nominal dimensions of 65x110x30,5 mm. Its bore diameter is 65 mm, outside diameter is 110 mm and overall assembled width is 30,5 mm.

What type of bearing is 807813 CT?

It is a single row tapered roller bearing designed to accommodate combined radial and axial loads.

What does CT mean in 807813 CT?

CT is the brand identifier associated with the supplied bearing. It should not be interpreted as a specific clearance class, cage material or precision grade without manufacturer documentation.

Can 807813 CT accommodate axial loads in both directions?

A single row tapered roller bearing supports axial loads in one direction. For axial location in both directions, an appropriately designed bearing arrangement is required, commonly using two opposed tapered roller bearings.

Are 807813 CT and 807813 GPZ interchangeable?

Both references are associated with the same nominal dimensions of 65x110x30,5 mm. However, interchangeability requires verification of internal geometry, ring dimensions, tolerances and operating characteristics.

Can 34513 URB replace 807813 CT?

Not without additional technical verification. Some catalogues indicate a different overall width for 34513 URB, which may prevent direct replacement.

Is 807813 CT a sealed bearing?

The bearing is described as an open tapered roller bearing. Lubricant retention and contamination protection must be provided by the surrounding mechanical assembly.

Does 807813 CT require preload adjustment?

Tapered roller bearings require appropriate axial adjustment. Depending on the application, this may involve a specified endplay or preload. The correct setting must be taken from the equipment manufacturer's technical documentation.
