DURBAL DGE 10 AW 10x30x7.9 Axial Spherical Plain Bearing

DURBAL DGE 10 AW is a maintenance-free axial spherical plain bearing from the DURBAL BASIC Line with principal dimensions of 10x30x7.9 mm. It uses a steel/PTFE sliding contact combination and has boundary dimensions according to DIN ISO 12240-3. For the exact DGE 10 AW size, DURBAL specifies a dynamic load rating of C = 36 kN, static load rating of C0 = 72 kN and tilt angle α = 10°.

The key technical identification is:

DURBAL + DGE 10 AW + 10x30x7.9 mm + steel/PTFE

DURBAL DGE 10 AW Dimensions

The manufacturer specifies:

d = 10 mm

d1 = 27.5 mm

dk = 32 mm

D = 30 mm

D1 = 16.5 mm

B = 7.9 mm

C = 6 mm

s = 7 mm

T = 9.5 mm

rs = 0.6 mm

r1s = 0.2 mm

The commonly used commercial size:

10x30x7.9 mm

corresponds to:

d x D x B

Therefore:

d = 10 mm

D = 30 mm

B = 7.9 mm

For engineering and installation purposes, however, the complete bearing geometry should be considered rather than relying solely on these three principal dimensions.

Axial Spherical Plain Bearing Design

DGE 10 AW is an axial spherical plain bearing designed primarily to accommodate axial loading through spherical sliding contact surfaces.

Unlike a ball or roller bearing, it does not use rolling elements.

Relative movement takes place between the spherical sliding surfaces, allowing the bearing to accommodate angular movement and misalignment within its permitted geometry.

For DGE 10 AW, the specified tilt angle is:

α = 10°

Steel/PTFE Sliding Contact Combination

DURBAL specifies the sliding contact combination as:

Steel / PTFE

The outer ring is manufactured from bearing steel, hardened and ground, with bonded PTFE fabric.

The spherical bearing component is manufactured from bearing steel and is:

hardened

ground

polished

and

hard chromium plated on the sliding surface.

This steel/PTFE combination is a key construction feature of the DGE AW series.

Maintenance-Free Design

DURBAL classifies the DGE AW series as:

Maintenance-free

The maintenance-free operating principle is associated with the steel/PTFE sliding contact combination.

The bearing should therefore not be treated as a conventional steel/steel spherical plain bearing requiring periodic relubrication of the sliding contact surfaces.

Installation and operating conditions must nevertheless comply with the manufacturer's requirements.

DURBAL DGE 10 AW Load Ratings

For the exact DGE 10 AW, DURBAL specifies:

Dynamic load rating C = 36 kN

Static load rating C0 = 72 kN

These ratings apply to this specific bearing size.

The C and C0 values of a spherical plain bearing should be interpreted using the manufacturer's calculation and selection principles rather than automatically applying the same service-life methodology used for conventional rolling bearings.

Tilt Angle

The specified value is:

α = 10°

This represents the angular movement permitted by the bearing geometry.

The ability to accommodate angular movement is one of the fundamental characteristics of a spherical plain bearing.

In an actual assembly, the usable angle may additionally be restricted by adjacent components and installation geometry.

DGE 10 AW and DIN ISO 12240-3

DURBAL states that the boundary dimensions of the DGE AW series comply with:

DIN ISO 12240-3

This standardization is relevant when evaluating dimensional compatibility.

However, compliance with the same dimensional standard does not by itself establish complete interchangeability between bearings from different manufacturers.

Sliding materials, internal geometry, load ratings and operating requirements must also be considered.

Selection and Interchangeability

When selecting a replacement for DURBAL DGE 10 AW, verify at least:

DURBAL designation DGE 10 AW

bearing type - axial spherical plain bearing

d = 10 mm

D = 30 mm

B = 7.9 mm

complete installation dimensions

steel/PTFE sliding contact combination

maintenance-free design

required axial load capacity

required tilt angle

adjacent component geometry

operating conditions

A bearing with nominal dimensions of 10x30x7.9 mm should not automatically be considered technically interchangeable with DGE 10 AW solely because its three principal dimensions are identical.

FAQ

What are the dimensions of DURBAL DGE 10 AW?

The principal dimensions are d = 10 mm, D = 30 mm and B = 7.9 mm, commonly expressed as 10x30x7.9 mm.

What type of bearing is DURBAL DGE 10 AW?

It is an axial spherical plain bearing.

Is DGE 10 AW a ball bearing?

No. It is a spherical plain bearing and does not contain balls, rollers or other rolling elements.

What is the sliding contact combination?

DURBAL specifies a steel/PTFE sliding contact combination.

Does DURBAL DGE 10 AW require relubrication?

DURBAL classifies the DGE AW series as maintenance-free.

What is the load rating of DGE 10 AW?

The manufacturer specifies a dynamic load rating C = 36 kN and static load rating C0 = 72 kN.

What is the tilt angle of DGE 10 AW?

The specified tilt angle is α = 10°.

Is every 10x30x7.9 bearing interchangeable with DGE 10 AW?

No. Bearing type, complete geometry, sliding contact materials, load ratings and application requirements must also be verified.

Engineer FAQ

Does 10x30x7.9 represent the complete geometry of DGE 10 AW?

No. It represents the principal d x D x B dimensions. DURBAL also specifies dimensions including d1, dk, D1, C, s and T.

What is the total dimension T?

For DGE 10 AW, DURBAL specifies T = 9.5 mm. This should not be confused with B = 7.9 mm.

Can C = 36 kN be interpreted like the dynamic rating of a ball bearing?

Not directly. Spherical plain bearings use manufacturer-specific selection and life calculation principles. The rating should be applied according to DURBAL's engineering guidance.

Does DIN ISO 12240-3 guarantee interchangeability?

No. Standardized boundary dimensions support dimensional comparison, but sliding materials, internal construction, load ratings and operating requirements must also be verified.

What is the safest identification when selecting a replacement?

Use the complete combination:

DURBAL + DGE 10 AW + axial spherical plain bearing + steel/PTFE + 10x30x7.9 mm
