CORTECO 01032573 NBR 35x62x10 - Radial Shaft Oil Seal

CORTECO 01032573 NBR 35x62x10 - Radial Shaft Oil Seal

CORTECO 01032573 is an NBR radial shaft oil seal with dimensions 35x62x10 mm, designed for dynamic sealing between a rotating shaft and a stationary housing. The seal helps retain oil or grease inside the mechanical assembly while protecting the sealing area against external contamination. The 35 mm shaft diameter, 62 mm housing diameter and 10 mm width make the complete CORTECO part number important when selecting a replacement for gearboxes, drive systems, machinery and other rotating assemblies.

Dimensions 35x62x10 mm

The principal dimensions are:

Shaft diameter d: 35 mm
Housing diameter D: 62 mm
Seal width b: 10 mm

The 35x62x10 mm dimensions define the basic installation geometry.

However, dimensions alone should not be used to determine full interchangeability. Radial shaft seals with identical dimensions can differ in lip geometry, elastomer material and application-specific construction.

NBR Sealing Material

CORTECO 01032573 is manufactured with an NBR sealing element.

NBR, or nitrile butadiene rubber, is one of the most widely used elastomers for industrial and automotive shaft seals because it provides good resistance to:

• mineral oils
• lubricating greases
• many mineral oil based fluids
• abrasion under correctly specified operating conditions

Its properties make NBR particularly suitable for general oil sealing applications in transmissions, gearboxes and mechanical drive systems.

Radial Shaft Sealing Function

A Simmerring operates at the interface between a rotating shaft and stationary housing.

The sealing lip remains in contact with the shaft surface and creates a controlled sealing zone designed to limit lubricant leakage.

The main functions of CORTECO 01032573 include:

• retaining oil or grease
• reducing lubricant leakage along the shaft
• separating the lubricated mechanism from the external environment
• protecting internal mechanical components
• supporting stable lubrication conditions

Correct operation depends not only on the seal itself but also on shaft condition, alignment, surface finish, rotational speed and operating temperature.

Shaft Surface Requirements

The condition of the 35 mm shaft sealing surface has a direct influence on seal performance.

Before installing a new Simmerring, the shaft should be inspected for:

• wear grooves
• corrosion
• scratches
• mechanical damage
• excessive surface roughness

A new oil seal installed on a severely worn shaft may continue to leak even when the seal dimensions and material are correct.

Applications of CORTECO 01032573

The 35x62x10 mm radial shaft seal can be used in appropriately specified:

• gearboxes
• transmission systems
• rotating shafts
• industrial machinery
• agricultural machinery
• mechanical drive systems
• reduction gears
• automotive assemblies
• oil-lubricated mechanisms

The exact application should be confirmed against the CORTECO part number or the original equipment specification.

Replacement Selection - CORTECO 01032573

When identifying a replacement, verify:

Manufacturer: CORTECO
Part number: 01032573
Material: NBR
Dimensions: 35x62x10 mm
Shaft diameter: 35 mm
Housing diameter: 62 mm
Width: 10 mm
Seal design: according to the exact CORTECO specification

A generic NBR 35x62x10 oil seal should not automatically be considered a direct replacement. The complete design and application requirements should also correspond to the original seal.

Why the CORTECO Part Number Matters

The dimensions 35x62x10 mm are used by different radial shaft seals. Two products can therefore fit the same basic shaft and housing dimensions while differing in:

• sealing lip geometry
• secondary lip configuration
• external surface design
• elastomer specification
• application requirements

Using CORTECO 01032573 as the primary identification reference reduces the risk of selecting an incorrect seal based solely on dimensions.

Operational Advantages

NBR elastomer: suitable for many mineral oil and grease sealing applications.

35x62x10 mm geometry: clearly defined dimensions for shaft and housing installation.

Dynamic shaft sealing: designed for operation against a rotating shaft surface.

Lubricant retention: helps keep oil or grease inside the mechanical assembly.

Application versatility: suitable for many gearbox, transmission and machinery sealing positions.

CORTECO identification: the 01032573 reference enables precise product identification beyond dimensions alone.

FAQ - CORTECO 01032573

What are the dimensions of CORTECO 01032573?
The seal measures 35x62x10 mm, with a 35 mm inner diameter, 62 mm outer diameter and 10 mm width.

What material is CORTECO 01032573 made from?
The sealing element is manufactured from NBR, nitrile butadiene rubber.

Is CORTECO 01032573 a Simmerring?
Yes. It is a radial shaft sealing element commonly referred to as a Simmerring or rotary shaft oil seal.

Can CORTECO 01032573 be used with oil?
NBR is commonly used with many mineral oils and lubricating greases. Compatibility should always be checked for the specific operating fluid and temperature.

What shaft diameter is required for CORTECO 01032573?
