SIMRIT 45x65x15 COMBI SF1 NBR Rotary Shaft Seal

SIMRIT 45x65x15 COMBI SF1 NBR Rotary Shaft Seal

SIMRIT 45x65x15 COMBI SF1 NBR is a rotary shaft seal with nominal dimensions 45x65x15 mm, manufactured with the specific COMBI SF1 construction and an NBR sealing element. The product is identified by reference 12001894, with 82001894 used as an additional trade reference.

The complete technical identity is:

SIMRIT + 45x65x15 + COMBI SF1 + NBR + 12001894

SIMRIT 45x65x15 COMBI SF1 – Technical Characteristics

SIMRIT 45x65x15 Dimensions

The nominal dimensions are:

d: 45 mm – inside / shaft diameter

D: 65 mm – outside diameter

B: 15 mm – overall width

Complete dimensional designation:

45x65x15 mm

For this product, dimensions alone should not be used to determine interchangeability. The COMBI SF1 construction is an essential part of the product identification.

COMBI SF1 Construction

The key technical feature of SIMRIT 45x65x15 is its:

COMBI SF1

construction.

This distinguishes the product from a conventional radial shaft seal having the same nominal dimensions.

COMBI designs provide a more complex sealing arrangement for applications where the sealing area requires additional protection compared with a conventional single radial shaft sealing element.

For replacement identification, COMBI SF1 must therefore be treated as part of the exact product specification.

It should not be automatically converted to or replaced by generic designations such as TC, AO or BASL simply because another seal has the same 45x65x15 mm dimensions.

NBR Sealing Material

The specified sealing material is:

NBR – Nitrile Butadiene Rubber.

For this product, the material forms part of the exact identification:

45x65x15 + COMBI SF1 + NBR

The NBR designation alone does not confirm the exact compound or all operating limits of this specific seal.

Therefore, the following parameters should not be assigned without exact reference-specific technical documentation:

• exact NBR compound
• Shore A hardness
• minimum operating temperature
• maximum operating temperature
• maximum operating pressure
• maximum shaft surface speed

SIMRIT 12001894 / 82001894

The principal reference associated with the 45x65x15 COMBI NBR seal is:

12001894

An additional trade reference is:

82001894

EAN:

3358960018946

These identifiers provide a considerably more precise method of searching for the product than using SIMRIT 45x65x15 alone.

For B2B purchasing, maintenance and replacement identification, the complete combination:

12001894 + COMBI SF1 + 45x65x15 + NBR

should be used whenever possible.

JCB and New Holland Applications

Catalogue cross-reference data associates this 45x65x15 COMBI SF1 seal with applications for:

JCB

and

New Holland.

Additional numbers associated with this product include:

90450009

5135990

49351034

These numbers can be useful when identifying a seal removed from a particular machine.

The presence of JCB or New Holland in catalogue application data does not mean that this seal fits every machine produced by these manufacturers. The exact machine, assembly and OE/reference number should always be checked.

Why COMBI SF1 Matters When Selecting a Replacement

Two shaft seals may share the same basic dimensions:

45x65x15 mm

while having substantially different constructions.

When comparing an alternative with SIMRIT 45x65x15 COMBI SF1 NBR, verify:

• d: 45 mm
• D: 65 mm
• B: 15 mm
• COMBI SF1 construction
• NBR sealing material
• reference 12001894 / 82001894
• relevant machine or OE reference
• complete sealing geometry
• actual operating conditions

A standard 45x65x15 mm oil seal should therefore not automatically be considered interchangeable with this COMBI SF1 seal.

Technical Specification

FAQ

What are the dimensions of SIMRIT 12001894 COMBI SF1?

The nominal dimensions are d: 45 mm, D: 65 mm, B: 15 mm, giving the complete size 45x65x15 mm.

What type of seal is SIMRIT 45x65x15?

It is a COMBI SF1 rotary shaft seal, rather than a conventional TC or BASL radial shaft seal.

What material is SIMRIT 45x65x15 COMBI SF1 made from?

The specified sealing material is NBR – Nitrile Butadiene Rubber.

What is the reference for SIMRIT 45x65x15 COMBI SF1?

The principal reference is 12001894. The product is also associated with the additional trade reference 82001894.

What is the EAN for SIMRIT 12001894?

The EAN associated with this reference is 3358960018946.

Is SIMRIT 45x65x15 COMBI SF1 used in JCB machines?

Catalogue cross-reference data associates the seal with JCB applications, as well as New Holland. The exact machine and reference should be verified before installation.

Can a standard 45x65x15 oil seal replace COMBI SF1?

Not automatically. The COMBI SF1 construction is a key part of the technical specification, so identical 45x65x15 mm dimensions alone do not establish interchangeability.

Is COMBI SF1 the same as a TC oil seal?

No automatic equivalence should be assumed. COMBI SF1 should be retained as the exact construction designation when identifying this SIMRIT product.
