Base reference: 01030457
Trade Number: 82030457
Product type: Transmission shaft oil seal
Design: BASLRDX27
Material: ACM - Polyacrylate Rubber
Dimensions: 44x75x8 mm
Inside diameter d: 44 mm

JOHN DEERE OE: RE40370
The exact dimensions are:
d = 44 mm - inside diameter / nominal shaft diameter
D = 75 mm - outside diameter
B = 8 mm - width
Complete dimensions:
44x75x8 mm
All three dimensions should be verified when identifying a replacement.
Matching the nominal 44x75x8 mm dimensions alone does not establish complete technical interchangeability. The ACM material, BASLRDX27 design, dust lip configuration and directional sealing geometry should also correspond to the original requirements.
The exact CORTECO design designation associated with 01030457B is:
BASLRDX27
The complete technical identification is therefore:
CORTECO 01030457B
44x75x8 mm
ACM
BASLRDX27
Right-hand Twist
Additional dust lip
The complete BASLRDX27 designation is an important identification parameter when comparing this seal with other 44x75x8 mm radial shaft seals.
Manufacturer-specific design codes should not automatically be considered equivalent without comparing the actual seal construction.
CORTECO 01030457B incorporates an additional dust lip.
This secondary lip is positioned on the external side of the primary sealing area and helps reduce the ingress of external contamination.
It provides an additional barrier against:
Dust
Dirt
Fine particles
General environmental contamination
The presence of the dust lip is therefore an important technical characteristic when comparing 01030457B with other 44x75x8 mm shaft seals.
CORTECO 01030457B incorporates directional sealing geometry identified as:
Right-hand Twist
This describes a directional sealing feature associated with the working geometry of the seal.
It should not be interpreted as a right-hand mounting thread.
The specified twist direction forms part of the seal's technical design and should be considered when selecting a replacement.
Some radial shaft seals incorporate directional structures in the sealing area.
These structures are designed with a specific shaft rotation direction in mind.
Consequently:
Right-hand Twist
should not automatically be replaced with:
Left-hand Twist
or another directional design solely because the replacement has identical 44x75x8 mm dimensions.
For CORTECO 01030457B, the directional geometry forms part of the exact product specification.
The sealing material specified for CORTECO 01030457B is:
ACM - Polyacrylate Rubber
ACM is an elastomer used in radial shaft sealing applications, including applications involving compatible oils.
For this exact CORTECO reference, ACM is part of the product specification.
An NBR, FPM or other elastomeric seal with identical 44x75x8 mm dimensions should not automatically be considered technically equivalent.
CORTECO 01030457B is catalogued as a:
Transmission shaft oil seal
A radial shaft oil seal operates between a rotating shaft and a stationary housing.
The primary sealing area operates against the shaft surface to help retain the compatible operating medium within the assembly.
The additional dust lip provides a secondary protective function on the external side of the primary sealing area.
The confirmed JOHN DEERE OE reference associated with CORTECO 01030457B is:
JOHN DEERE RE40370
This OE reference is an important identification entity when searching for the seal for JOHN DEERE applications.
For technical selection, the OE number should be checked together with:
CORTECO 01030457B
44x75x8 mm
ACM
BASLRDX27
Right-hand Twist
and the specific machine or transmission application.
This product can be identified using several references:
01030457B
01030457
82030457
BASLRDX27
RE40370
The complete CORTECO product reference is:
01030457B
The base reference is:
01030457
The Trade Number is:
82030457
The design designation is:
BASLRDX27
The JOHN DEERE OE reference is:
RE40370
Retaining these identifiers in the product description supports precise identification in technical catalogues, purchasing systems and parts searches.
The principal parameters to verify are:
Reference - 01030457B
Dimensions - 44x75x8 mm
Material - ACM
Design - BASLRDX27
Dust lip - Yes
Directional geometry - Right-hand Twist
Trade Number - 82030457
JOHN DEERE OE - RE40370
For a directional radial shaft seal, the specified twist direction should be retained when selecting a technical replacement.
Three principal dimensions are used for basic radial shaft seal identification:
Inside diameter d
Outside diameter D
Width B
For CORTECO 01030457B:
d = 44 mm
D = 75 mm
B = 8 mm
A used elastomeric seal can be worn or deformed. Physical measurements should therefore preferably be considered together with the original seal markings.
No.
Radial shaft seals with identical:
44x75x8 mm
dimensions can differ in:
Sealing material
Primary lip geometry
Dust lip configuration
Directional sealing geometry
Outside diameter construction
Spring design
Operating characteristics
Manufacturer-specific construction
For this reason, matching dimensions alone do not establish complete technical interchangeability.
When comparing CORTECO 01030457B with a seal from another manufacturer, verify:
44x75x8 mm dimensions
ACM sealing material
BASLRDX27 construction
Additional dust lip
Right-hand Twist
Operating medium
Temperature requirements
Shaft speed
Pressure conditions
JOHN DEERE RE40370 where applicable
Operating limits from another 44x75x8 mm seal should not be transferred to CORTECO 01030457B solely because the dimensions match.
