Simrit 105x140x12 FPM Radial Shaft Seal

Simrit 105x140x12 FPM Radial Shaft Seal

Simrit 105x140x12 FPM is a radial shaft seal / rotary shaft seal / oil seal with nominal dimensions of 105x140x12 mm, manufactured from FPM fluoroelastomer. Its principal installation dimensions are d = 105 mm, D = 140 mm and B = 12 mm.

Based on the available identification, the technically safe product specification is:

Simrit + 105x140x12 mm + FPM

The exact Simrit/Freudenberg design profile should not be inferred without the corresponding article number or complete manufacturer designation.

Simrit 105x140x12 FPM - Technical Characteristics

Brand: Simrit

Product type: Radial Shaft Seal / Rotary Shaft Seal / Oil Seal

Material: FPM

Material family: Fluoroelastomer

Dimensions: 105x140x12 mm

Shaft diameter d: 105 mm

Outside diameter D: 140 mm

Width B: 12 mm

Seal design/profile: Not confirmed

Additional dust lip: Not confirmed

The dimensions and elastomer material should be retained together when identifying this seal.

Simrit 105x140x12 Dimensions

Nominal dimensions:

d = 105 mm - nominal shaft diameter

D = 140 mm - nominal outside diameter / housing bore diameter

B = 12 mm - nominal axial width

Complete dimensions:

105x140x12 mm

All three dimensions are relevant to installation and replacement selection.

The designation should not be simplified to 105x140 mm, because the 12 mm axial width is an integral part of the dimensional specification.

FPM Fluoroelastomer

The specified material is:

FPM - fluoroelastomer

Material is an integral part of the exact product identification:

105x140x12 + FPM

A shaft seal with identical 105x140x12 mm dimensions but manufactured from NBR, ACM, MVQ or another elastomer represents a different material variant.

The exact FPM compound used for this specific Simrit product has not been identified. Therefore, a specific hardness, exact operating temperature range, maximum pressure or maximum shaft speed should not be assigned without the corresponding product-specific manufacturer data.

FPM vs FKM vs Viton®

FPM is a designation commonly used in European technical documentation for fluoroelastomer materials. FKM is another widely used designation for this elastomer family.

However, Viton® is a trademark and should not automatically be used as a synonym for every FPM/FKM shaft seal.

Unless the specific compound is confirmed as genuine Viton®, the technically appropriate description for this product is:

FPM fluoroelastomer

Simrit Seal Design

The available designation:

Simrit 105x140x12 FPM

does not identify the exact manufacturer-specific seal profile.

Therefore, this product should not automatically be classified as:

BA

BASL

B1SL

or another Simrit/Freudenberg design.

Likewise, the presence or absence of an additional dust lip should not be inferred from dimensions and material alone.

The exact article number or manufacturer designation is required for precise identification of the seal construction.

How Does a Radial Shaft Seal Work?

A radial shaft seal operates between a:

rotating shaft

and a

stationary housing

For this product, the nominal installation dimensions are:

Shaft: 105 mm

Housing bore: 140 mm

Axial width: 12 mm

The precise sealing-lip configuration depends on the exact Simrit design variant.

Actual sealing performance also depends on application conditions such as shaft surface condition, runout, alignment, rotational speed, temperature, pressure, lubrication and the sealed medium.

Simrit 105x140x12 vs 105x140x13

The two sizes share:

d = 105 mm

D = 140 mm

but differ in axial width:

105x140x12: B = 12 mm

105x140x13: B = 13 mm

The difference is 1 mm.

They should not automatically be considered interchangeable. A different axial width can affect installation depth and the axial position of the sealing lip on the shaft surface.

Simrit 105x140x12 FPM vs CORTECO 12001466 ACM B2SL

The previously identified CORTECO variant has:

CORTECO 12001466

105x140x13 mm

ACM

B2SL

This Simrit product is identified as:

Simrit

105x140x12 mm

FPM

The products therefore differ in at least two fundamental parameters:

Width: 12 mm vs 13 mm

Material: FPM vs ACM

They should not be considered interchangeable solely because both have 105 mm shaft and 140 mm outside diameters.

Selection and Interchangeability

When selecting a replacement for Simrit 105x140x12 FPM, verify:

d = 105 mm

D = 140 mm

B = 12 mm

FPM material

exact Simrit design profile

lip configuration

sealed medium

operating temperature

shaft rotational speed

pressure conditions

shaft surface condition

runout and alignment

installation geometry

If the Freudenberg/Simrit article number is available, it should be used together with dimensions, material and design profile for precise replacement identification.

FAQ

What are the dimensions of the Simrit 105x140x12 FPM seal?

The nominal dimensions are 105x140x12 mm: d = 105 mm, D = 140 mm and B = 12 mm.

What material is this Simrit seal made from?

The specified material is FPM fluoroelastomer.

Is FPM the same as Viton®?

Not automatically. Viton® is a trademark. It should only be used when the specific material has been confirmed as genuine Viton®.

Does this Simrit 105x140x12 seal have a dust lip?

The lip configuration cannot be reliably determined from the dimensions and FPM material alone. The exact Simrit/Freudenberg article number is required.

Is 105x140x12 interchangeable with 105x140x13?

Not automatically. The axial widths differ by 1 mm, which can affect installation geometry and sealing-lip position.

Can an NBR 105x140x12 seal replace this FPM variant?

Not automatically. NBR and FPM are different elastomer families. Material compatibility with the operating conditions must be verified.

How can the exact Simrit design be identified?

Use the Freudenberg/Simrit article number, complete dimensions, material and manufacturer-specific design designation.

Is every 105x140x12 oil seal interchangeable?

No. Identical dimensions alone do not establish interchangeability. Material, lip design and application requirements must also be checked.

Engineer FAQ

What does d = 105 mm represent?

It is the nominal shaft diameter associated with the seal.

What does D = 140 mm represent?

It is the nominal outside diameter corresponding to the nominal housing bore diameter.

What does B = 12 mm represent?

It is the nominal axial width of the seal and an integral installation parameter.

Can an exact operating temperature be specified?

Not without confirmation of the exact FPM compound used for this specific Simrit product.

What is the safest identification for replacement selection?

With the currently available data, use:

Simrit + 105x140x12 mm + FPM

and verify the exact article number and seal profile before establishing technical interchangeability.
