T7FC 080/QCL7C Dimensions 80x160x45 mm

The principal dimensions of the SKF T7FC 080/QCL7C bearing are:

d: 80 mm
D: 160 mm
T: 45 mm
B: 41 mm
C: 31 mm

An important distinction when identifying this bearing is that 45 mm represents the overall bearing width T.

The inner ring width B is 41 mm, while the outer ring width C is 31 mm.

These dimensions should not be treated as interchangeable when comparing the T7FC 080/QCL7C with another tapered roller bearing.

Single Row Tapered Roller Bearing Design

The T7FC 080/QCL7C SKF uses tapered rollers operating between tapered inner and outer ring raceways.

The geometry of a tapered roller bearing is designed so that the contact lines of the rolling elements and raceways converge toward a common point on the bearing axis.

This construction allows the bearing to accommodate radial and axial forces simultaneously.

A single-row tapered roller bearing primarily supports axial load in one direction. Where axial loads act in both directions, tapered roller bearings are commonly used in opposed or paired arrangements according to the requirements of the assembly.

Combined Radial and Axial Load Capacity

A key characteristic of the SKF T7FC 080/QCL7C is its ability to operate under combined loading.

Unlike a bearing intended primarily for radial loads, tapered roller geometry allows forces to be transmitted at an angle through the rollers and raceways.

This makes tapered roller bearings particularly relevant to mechanical systems exposed to:

• high radial loads
• simultaneous radial and axial forces
• shaft positioning requirements
• demanding transmission loads
• continuously changing mechanical forces

Actual permissible loads depend on the complete bearing arrangement, lubrication, speed, temperature and operating conditions.

Separable Cup and Cone Construction

The bearing consists of two principal assemblies.

The cone includes the inner ring together with the tapered rollers and cage.

The cup is the separate outer ring.

This separable construction facilitates mounting and allows the components to be installed independently during assembly.

It also makes correct adjustment particularly important. Depending on the bearing arrangement, the required operating clearance or preload must be established according to the machine design and installation requirements.

T7FC 080/QCL7C for Heavy Industrial Applications

With an 80 mm bore and 160 mm outside diameter, the T7FC 080/QCL7C belongs to a size range relevant to substantial rotating assemblies.

The bearing can be considered for appropriately designed:

• industrial gearboxes
• heavy-duty transmissions
• drive systems
• industrial machinery
• construction equipment
• agricultural machinery
• mechanical power transmission systems
• large rotating shafts
• heavy equipment

The exact application should always be verified against the machine manufacturer's technical requirements.

Bearing Width T, B and C Explained

Tapered roller bearings commonly specify several different width dimensions.

For the T7FC 080/QCL7C:

T = 45 mm - total assembled bearing width
B = 41 mm - inner ring width
C = 31 mm - outer ring width

This distinction is important when identifying a replacement bearing.

For example, specifying the bearing simply as 80x160x41 mm would be misleading because 41 mm represents the inner ring width rather than the complete bearing width.

The primary dimensional designation should therefore remain 80x160x45 mm.

Correct Mounting and Adjustment

Correct installation is particularly important for tapered roller bearings.

The mounting procedure should take into account:

• shaft and housing fits
• bearing alignment
• operating clearance
• preload where specified
• lubrication
• shaft rigidity
• operating temperature
• load direction

Incorrect adjustment can increase friction and operating temperature or negatively affect load distribution and bearing service life.

Lubrication of Tapered Roller Bearings

Lubrication creates a separating film between the rolling elements, raceways and other contacting surfaces.

The lubricant should be selected according to operating speed, temperature, load and environmental conditions.

Both grease and oil lubrication may be used in tapered roller bearing arrangements depending on the machine design.

Contamination control is also important because hard particles entering the bearing can damage the precision raceway and roller surfaces.

Operational Advantages

Combined load capability: tapered geometry enables simultaneous accommodation of radial and axial forces.

80x160x45 mm dimensions: clearly defined geometry for bearing identification and replacement selection.

Single-row construction: suitable for applications requiring axial load accommodation primarily in one direction.

Separable design: the cup can be separated from the cone assembly, facilitating mounting and adjustment.

Large 80 mm bore: suitable for appropriately dimensioned industrial shafts and heavy mechanical assemblies.

SKF identification: provides precise manufacturer and bearing designation for purchasing, MRO and warehouse stock management.

Frequently Asked Questions by Engineers

Why are T, B and C different in a tapered roller bearing?
The cone and cup have different axial widths. T represents the total assembled bearing width, while B and C describe the widths of the inner and outer rings respectively.

Is 80x160x45 sufficient for identifying the correct replacement?
No. The complete designation T7FC 080/QCL7C SKF should also be verified because bearings with similar principal dimensions can differ in internal design and performance characteristics.

Can T7FC 080/QCL7C operate under combined loading?
Yes. Combined radial and axial load accommodation is one of the fundamental characteristics of tapered roller bearing geometry.

Can two tapered roller bearings support axial loads in both directions?
Yes. Appropriate opposed bearing arrangements can provide axial location in both directions. The specific arrangement and adjustment depend on the machine design.

Why is bearing adjustment important?
Tapered roller bearing performance depends on the operating clearance or preload established in the complete arrangement. Incorrect adjustment can adversely affect friction, temperature, load distribution and service life.
