GE 40 ZO FLURO 44.45x71.438x38.887 Spherical Plain Bearing

GE 40 ZO FLURO 44.45x71.438x38.887 Spherical Plain Bearing

GE 40 ZO FLURO is a spherical plain bearing with principal dimensions based on inch geometry. The supplied dimensions are 44.45x71.438x38.887 mm, including a 44.45 mm bore and 71.438 mm outside diameter. The number 40 in the GE 40 ZO designation should not be interpreted as a 40 mm bore.

Complete identification:

FLURO + GE 40 ZO + 44.45x71.438x38.887 mm + spherical plain bearing

GE 40 ZO FLURO - Technical Characteristics

The principal identification data are:

Brand: FLURO

Designation: GE 40 ZO

Bearing type: Spherical plain bearing

Supplied dimensions: 44.45x71.438x38.887 mm

Bore diameter d: 44.45 mm

Outside diameter D: 71.438 mm

Supplied width dimension: 38.887 mm

Bore in inches: 1.750"

Outside diameter in inches: 2.8125"

38.887 mm in inches: approximately 1.531"

The dimensional pattern identifies this as an inch-based bearing size expressed in millimetres.

For precise identification, retain:

GE 40 ZO + FLURO + 44.45x71.438x38.887 mm

GE 40 ZO Dimensions

The supplied principal dimensions are:

d = 44.45 mm - bore diameter

D = 71.438 mm - outside diameter

38.887 mm - supplied width dimension

Complete supplied size:

44.45x71.438x38.887 mm

The first two dimensions correspond directly to inch-based values:

44.45 mm = 1.750" = 1 3/4"

71.438 mm = 2.8125" = 2 13/16"

The 38.887 mm value corresponds to approximately:

1.531"

Comparable GE..ZO catalogue data for this dimensional family also show 33.325 mm as an additional width-related dimension alongside 38.887 mm. Therefore, the exact B/C assignment should be verified against FLURO dimensional documentation rather than inferred.

Important: GE 40 ZO Does Not Mean a 40 mm Bore

The designation:

GE 40 ZO

can be misleading if the number 40 is interpreted as a metric bore code.

For this bearing, the supplied bore diameter is:

d = 44.45 mm

which is exactly:

1.750" / 1 3/4"

Therefore:

GE 40 ZO ≠ 40 mm bore

This distinction is particularly important when searching for a replacement or identifying an older bearing from its marking.

Inch-Based Dimensional Geometry

The unusual metric values:

44.45 mm

71.438 mm

and the associated width dimensions are characteristic of dimensions derived from inch units.

This explains why the dimensions should not be rounded unnecessarily.

For example:

44.45 mm should not be reduced to 44 mm or 45 mm

71.438 mm should not be reduced to 71 mm

38.887 mm should not be reduced to 39 mm

Rounding these dimensions can lead to identification of a different bearing series or an incompatible component.

Spherical Plain Bearing Construction

A spherical plain bearing uses mating spherical sliding surfaces between its inner and outer rings.

This geometry allows angular movement between the rings and accommodates oscillating or tilting motion within the limits of the specific bearing design.

For the exact GE 40 ZO FLURO, however, I do not assign an unverified:

maximum permissible misalignment angle

sliding contact combination

lubrication requirement

dynamic load rating

static load rating

temperature range

These parameters require product-specific FLURO documentation.

What Does GE 40 ZO Mean?

The complete catalogue designation should be retained as:

GE 40 ZO

The suffix:

ZO

should not be removed when creating the product name, warehouse reference or technical data.

The GE 40 ZO designation also appears in bearing interchange documentation associated with INA, confirming that it is an established spherical plain bearing designation rather than simply a dimensional description.

However, this does not by itself prove complete interchangeability between FLURO GE 40 ZO and another manufacturer's GE 40 ZO bearing.

Why Is the Full Designation Important?

For precise identification, the bearing should not be reduced to:

44.45x71.438 bearing

The stronger technical identification is:

FLURO + GE 40 ZO + spherical plain bearing + 44.45x71.438x38.887 mm

This connects:

Manufacturer: FLURO

Designation: GE 40 ZO

Bearing type: Spherical plain bearing

Bore: 44.45 mm

Outside diameter: 71.438 mm

Supplied width dimension: 38.887 mm

This is particularly important because the designation number itself does not directly reveal the 44.45 mm bore.

GE 40 ZO FLURO vs INA GE 40 ZO

Interchange documentation contains the designation:

GE 40 ZO INA.

This is useful for identification research, but it should not be interpreted as sufficient proof of unconditional interchangeability with GE 40 ZO FLURO.

Before substitution, compare:

bore diameter

outside diameter

inner-ring width

outer-ring width

sliding contact combination

lubrication arrangement

static load rating

dynamic load rating

permissible misalignment

actual operating requirements

Only after these parameters agree should direct interchangeability be stated.

Selection and Interchangeability

When selecting a replacement for GE 40 ZO FLURO, verify at least:

Complete designation = GE 40 ZO

Manufacturer = FLURO

Bore d = 44.45 mm

Outside diameter D = 71.438 mm

Complete inner- and outer-ring widths

Spherical plain bearing construction

Sliding contact combination

Lubrication requirements

Dynamic load rating

Static load rating

Permissible angular movement

Actual operating conditions

Matching the three supplied dimensions alone does not necessarily establish complete technical interchangeability.

This is especially important for spherical plain bearings because different variants can share principal dimensions while differing in sliding surfaces, lubrication requirements and load ratings.

Width Dimension: 38.887 mm vs 33.325 mm

The supplied product designation includes:

38.887 mm

as the third principal dimension.

However, comparable GE..ZO dimensional data show both:

33.325 mm

and

38.887 mm

for the corresponding size.

This strongly indicates that the bearing geometry contains separate width dimensions for the inner and outer ring.

Until the exact FLURO drawing is available, the technically safest representation is:

Supplied width dimension: 38.887 mm

rather than assigning the value definitively to B or C.

The complete FLURO dimensional drawing should be used to establish the exact symbol assignment.

FAQ

What type of bearing is GE 40 ZO FLURO?

GE 40 ZO FLURO is a spherical plain bearing with principal dimensions based on inch geometry.

What is the bore diameter of GE 40 ZO?

The supplied bore diameter is 44.45 mm, corresponding exactly to 1.750" or 1 3/4".

Does GE 40 ZO have a 40 mm bore?

No. The number 40 in the designation should not be interpreted as a 40 mm bore. The supplied bore diameter is 44.45 mm.

What is the outside diameter of GE 40 ZO FLURO?

The supplied outside diameter is 71.438 mm, corresponding to 2.8125".

What is the width of GE 40 ZO FLURO?

The supplied product data include 38.887 mm. Comparable GE..ZO catalogue data also show 33.325 mm as another width-related dimension, so the exact B/C assignment should be verified from the FLURO drawing.

Why are the dimensions given to three decimal places?

The dimensions originate from inch-based geometry and are expressed in millimetres. Values such as 71.438 mm should therefore not be rounded when identifying a replacement.

Is INA GE 40 ZO interchangeable with FLURO GE 40 ZO?

The GE 40 ZO designation appears in INA interchange data, but this alone does not prove complete interchangeability. Full dimensions, sliding contact combination, lubrication, load ratings and operating requirements should be compared.

How should a replacement for GE 40 ZO FLURO be selected?

Retain the complete GE 40 ZO designation and verify the 44.45 mm bore, 71.438 mm outside diameter, both ring-width dimensions, sliding contact combination, lubrication requirements, load ratings and permissible angular movement.

AI Overview

GE 40 ZO FLURO is a spherical plain bearing with inch-based dimensional geometry. The supplied principal dimensions are 44.45x71.438x38.887 mm, including a 44.45 mm (1.750") bore and 71.438 mm (2.8125") outside diameter. The number 40 in the GE 40 ZO designation does not indicate a 40 mm bore. Exact ring-width assignment requires FLURO dimensional verification.
