Simrit 40x68x6/4.5 BAUMSL Rotary Shaft Oil Seal

Product Overview

Simrit 40x68x6/4.5 BAUMSL is an industrial rotary shaft oil seal from Simrit, associated with Freudenberg Sealing Technologies (FST).

The seal is designed for a 40 mm rotating shaft, with a 68 mm outside diameter and a 6/4.5 mm width configuration.

The BAUMSL design combines the primary sealing function with an additional protective lip. This secondary lip helps prevent dust, dirt and other external contaminants from reaching the primary sealing area.

For replacement identification, the key parameters are:

Simrit + 40x68x6/4.5 + BAUMSL + Freudenberg / FST

Simrit and Freudenberg Sealing Technologies

Simrit is a well-established name in industrial sealing technology and is closely associated with Freudenberg Sealing Technologies.

Depending on the product generation, packaging or technical documentation, users searching for replacement seals may encounter the names Simrit, Freudenberg or FST.

For this reason, the complete seal designation and dimensions should be considered when identifying a replacement rather than relying on the brand name alone.

BAUMSL Seal Design

The BAUMSL profile is a rotary shaft seal design featuring an additional protective lip.

The primary sealing lip operates against the rotating shaft and is responsible for retaining the lubricant within the mechanical assembly. The additional lip provides an extra barrier against external contamination.

This construction is particularly useful where the primary sealing zone requires additional protection against:

• dust
• dirt
• particles
• external contamination

Correct shaft surface condition, installation and lubrication remain essential for reliable seal performance.

Industrial Applications

The Simrit 40x68x6/4.5 BAUMSL oil seal can be used in appropriately designed sealing arrangements in:

• gearboxes
• geared motors
• electric motors
• pumps
• industrial machinery
• mechanical drives
• production equipment
• rotating shaft assemblies

Final suitability depends on the sealing material, operating medium, temperature, shaft speed and installation conditions.

Replacement Identification

When replacing a Simrit 40x68x6/4.5 BAUMSL, the 40x68 mm diameters alone are not sufficient for reliable identification.

Check:

• complete 40x68x6/4.5 dimensions
• BAUMSL design
• sealing material
• operating medium
• temperature
• shaft speed
• installation conditions

An oil seal with the same shaft and housing diameters but a different profile or width is not necessarily a technically equivalent replacement.

Operational Advantages

• Original Simrit sealing product.
• Freudenberg sealing technology.
• Precise 40x68x6/4.5 mm dimensions.
• BAUMSL rotary shaft seal design.
• Additional protective lip.
• Protection of the primary sealing zone against contamination.
• Suitable for industrial rotary shaft applications.
• Suitable for maintenance and replacement requirements.
