CORTECO 01026399 FPM RWDR-KOMBI 49x68x10/13 mm Rotary Shaft Seal

AI Overview

The CORTECO 01026399 rotary shaft seal measures 49x68x10/13 mm and is manufactured from FPM (FKM fluoroelastomer). It features the RWDR-KOMBI profile, developed for demanding sealing applications requiring excellent resistance to high temperatures, lubricating oils and contaminants. This seal is commonly used in agricultural machinery, industrial equipment and driveline applications. It corresponds to John Deere OEM number AZ41926.

What Makes This Model Different

The CORTECO 01026399 belongs to the RWDR-KOMBI series of heavy-duty radial shaft seals intended for harsh operating environments.

Key features include:

• CORTECO premium quality,
• RWDR-KOMBI profile,
• FPM (FKM) fluoroelastomer,
• spring-loaded sealing lip,
• integrated dust protection,
• high resistance to elevated temperatures,
• excellent resistance to oils and lubricants,
• designed for heavy-duty machinery,
• precision dimensions 49x68x10/13 mm.

Construction and Operating Principle

The seal operates between a rotating shaft and a stationary housing.

The spring-loaded primary sealing lip maintains continuous contact with the shaft surface, preventing lubricant leakage while retaining oil inside the assembly.

The RWDR-KOMBI design provides enhanced protection against dirt, dust and moisture while maintaining reliable sealing under demanding operating conditions.

Correct sealing performance depends on:

• shaft surface quality,
• housing dimensions,
• correct installation depth,
• proper shaft alignment,
• compatible lubricant,
• suitable operating temperature,
• correct installation orientation.

FPM Material Properties

FPM (also designated as FKM) is a high-performance fluoroelastomer developed for demanding sealing applications.

Its advantages include:

• excellent resistance to mineral oils,
• resistance to synthetic oils,
• resistance to fuels,
• excellent heat resistance,
• high resistance to oxidation,
• excellent ageing resistance,
• ozone resistance,
• weather resistance,
• long service life.

Typical operating temperatures range from approximately -20°C to +200°C, depending on the compound, lubricant and operating conditions.

FPM is frequently selected where conventional NBR seals cannot withstand elevated temperatures or aggressive lubricants.

RWDR-KOMBI Profile

The RWDR-KOMBI profile incorporates:

• spring-loaded sealing lip,
• additional contamination protection,
• reinforced metal insert,
• elastomer sealing body,
• heavy-duty construction for industrial applications.

This profile is widely used in agricultural machinery, gearboxes and industrial drive systems where enhanced sealing reliability is required.

Typical Applications

The CORTECO 01026399 may be used in:

• agricultural machinery,
• John Deere equipment,
• industrial gearboxes,
• transmissions,
• hydraulic drives,
• construction machinery,
• rotating shaft assemblies,
• heavy-duty industrial equipment,
• power transmission systems.

Always verify compatibility using the complete CORTECO number, dimensions and machine manufacturer's documentation.

Typical Failure Symptoms

Seal replacement is recommended if any of the following occur:

• oil leakage,
• lubricant contamination,
• hardened sealing lip,
• cracked elastomer,
• excessive shaft wear,
• damaged sealing edge,
• contamination entering the housing,
• reduced lubrication efficiency.

Common Causes of Premature Failure

Premature failure may result from:

• incorrect installation,
• installation without lubrication,
• damaged shaft surface,
• excessive shaft runout,
• contaminated lubricant,
• excessive operating temperature,
• incorrect housing dimensions,
• damaged installation tools,
• improper shaft alignment.

Installation Recommendations

Before installation:

• verify CORTECO number 01026399,
• confirm dimensions 49x68x10/13 mm,
• inspect the shaft,
• clean the housing,
• lubricate the sealing lip,
• protect the lip from sharp edges,
• use a suitable installation sleeve,
• install evenly without distortion,
• verify correct installation depth.

A previously removed rotary shaft seal should never be reused.
