807813 P6 BBC-R 65x110x30,5 mm - Single Row Tapered Roller Bearing

807813 P6 BBC-R - Product Characteristics

The 807813 P6 BBC-R belongs to the family of single row tapered roller bearings designed for mechanical assemblies subjected to combined radial and axial loading.

Its tapered rolling elements operate between conical inner and outer raceways. This geometry allows the bearing to accommodate radial forces together with axial forces acting in one direction.

The separable construction enables the outer ring to be installed independently from the inner ring assembly, which contains the tapered rollers and cage.

The distinguishing feature of this variant is its P6 precision designation, which specifies tighter dimensional and running tolerances than the normal precision class.

Precision class P6 does not automatically indicate higher dynamic load capacity, greater fatigue life or higher permissible rotational speed.

Correct mounting, lubrication and axial adjustment remain essential to bearing performance.

Technical Specifications - 807813 P6 BBC-R

The discrepancy between the specified width of 30,5 mm and the 30,25 mm width listed for the base BBC-R 807813 reference must be resolved before confirming dimensional interchangeability.

What Does 807813 P6 BBC-R Mean?

The designation identifies the bearing reference, precision class and brand.

807813 - Bearing Reference

807813 identifies a single row tapered roller bearing within the manufacturer's catalogue system.

The reference is associated with a nominal bore diameter of 65 mm and outside diameter of 110 mm.

However, the exact overall width must be checked against the full manufacturer designation because catalogue information differs between related variants.

P6 - Precision Class

P6 identifies a bearing precision class corresponding to ISO tolerance class 6.

Compared with the normal precision class, P6 provides tighter tolerances for specified dimensional and rotational accuracy characteristics.

These may include bore and outside diameter tolerances, dimensional variation and running accuracy.

The exact permitted deviations depend on the applicable standard and bearing type.

P6 does not mean that the bearing has increased radial internal clearance. Precision class and internal clearance are different technical characteristics.

BBC-R - Bearing Brand

BBC-R identifies the bearing brand.

The brand designation alone does not define the cage material, lubricant, load rating or operating temperature range.

65x110x30,5 mm - Nominal Dimensions

The supplied dimensional designation refers to:

• 65 mm bore diameter.

• 110 mm outside diameter.

• 30,5 mm overall bearing width.

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

The exact overall width of this BBC-R variant requires confirmation.

Construction and Operating Principle

The 807813 P6 BBC-R tapered roller bearing consists of an inner ring, outer ring, tapered rollers and a cage.

The inner and outer rings contain conical raceways. The tapered rollers transmit forces between these raceways, allowing the bearing to accommodate combined radial and axial loading.

The tapered geometry also produces an axial force component when the bearing is subjected to radial loading. This must be considered when designing the bearing arrangement.

A single row tapered roller bearing supports externally applied axial loads in one direction.

Where axial location is required in both directions, an appropriate opposed bearing arrangement is commonly used.

The separable construction allows independent installation of the outer ring and inner ring assembly.

The open design requires suitable lubrication and protection against contamination.

807813 P6 BBC-R Compared with Other 807813 Variants

Bearings within the 807813 reference family may differ in precision class, construction details and overall width.

807813 P6 vs 807813 without P6

The P6 designation identifies a tighter tolerance class.

A bearing without P6 should not automatically be used as a replacement when the application requires the specified precision.

807813 P6 vs 807813 A P6

The additional A designation may identify a technically significant construction or dimensional variant.

Commercial listings associate 807813 A P6 BBC-R with dimensions of 65x110x30,5 mm.

However, this does not establish that the designation without A has identical dimensions or internal geometry.

Before substitution, the full manufacturer reference must be verified.

Alternative Designations and Reference Formats

The following formats may be useful for identifying the product:

• 807813 P6 BBC-R

• BBC-R 807813 P6

• 807813 P6 tapered roller bearing

• BBC-R tapered roller bearing 807813 P6

• 807813 P6 BBC-R 65x110x30,5 mm

A related commercial designation is 807813 A P6 BBC-R.

The additional A element must not be omitted when confirming an exact replacement.

No unverified OEM references or direct interchangeability claims are assigned to the specified product.

Applications of 807813 P6 BBC-R

Single row tapered roller bearings are used in mechanical assemblies requiring combined radial and axial load support.

Typical applications for this bearing construction include appropriately designed wheel hub assemblies, mechanical transmissions and rotating shaft supports.

The P6 precision class may be specified where tighter dimensional and running accuracy is required.

However, this does not establish a confirmed application of the exact 807813 P6 BBC-R reference in any particular vehicle or machine.

Compatibility must be determined using the original equipment documentation and the complete bearing designation.

Bearing Selection and Interchangeability

Before purchasing 807813 P6 BBC-R or selecting an alternative, verify the following:

1. Complete bearing designation: 807813 P6 BBC-R, including any additional A designation.

2. Bore diameter: 65 mm.

3. Outside diameter: 110 mm.

4. Overall width: Confirm whether the required dimension is 30,5 mm or 30,25 mm.

5. Precision class: P6.

6. Individual ring dimensions: Inner ring width, outer ring width and assembled geometry.

7. Internal construction: Contact angle, roller geometry and cage configuration.

8. Operating requirements: Load, speed, lubrication, temperature and axial adjustment.

Matching bore and outside diameters does not guarantee interchangeability.

Even a small difference in overall width can affect axial positioning, bearing adjustment and the operation of the complete assembly.

Installation and Operating Recommendations

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

Apply mounting force only to the ring being installed 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 protected from contamination.

Axial endplay or preload must be adjusted according to the equipment manufacturer's specifications.

Excessive preload can increase friction and operating temperature. Excessive clearance can affect running accuracy and shaft positioning.

Use the specified lubricant and follow the recommended lubrication procedure.

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