CORTECO 19034042 ACM RHSC Rotary Shaft Seal 68x88x8

Main Description

The CORTECO 19034042 ACM RHSC is a premium rotary shaft seal designed for challenging industrial and automotive applications. With its 68 mm inside diameter, 88 mm outside diameter, and 8 mm cross-section, this oil seal provides a secure and efficient seal on rotating shafts where long-lasting performance is essential.

Constructed from ACM (acrylic rubber), this seal offers outstanding resistance to oils, grease, and high temperatures, making it ideal for both engine and mechanical environments. The RHSC design provides a double-lip configuration that significantly improves protection— the primary lip ensures tight sealing, while the secondary lip keeps out contaminants such as dust and debris.

This shaft sealing ring is engineered for high durability and reliable operation in applications that demand robust sealing. Its rotary seal design ensures low friction and minimal leakage, helping to maintain system integrity over prolonged use. Whether in industrial machinery, gearboxes, transmissions, or engine assemblies, this oil seal delivers excellent performance under variable operating conditions.

As a technical seal, it reduces maintenance needs due to its durable construction and resistant material. The combination of ACM and the RHSC geometry helps to accommodate shaft misalignments and thermal expansions, preserving the seal’s effectiveness throughout its service life.

FAQ

Q1: What does ‘RHSC’ mean for this seal?
A1: RHSC describes a double-lip seal design: a primary sealing lip for oil retention and a secondary dust lip to block contaminants, improving sealing reliability.

Q2: Why is ACM used for this type of oil seal?
A2: ACM (acrylic rubber) offers excellent chemical resistance to lubricants, grease, and oils, as well as good temperature stability, which ensures long-term performance.

Q3: How do I choose the correct rotary shaft seal size?
A3: Measure the shaft diameter (inner seal dimension), the housing bore diameter (outer seal dimension), and required thickness or cross-section. For this seal, the correct size is 68x88x8 mm.

Q4: In which applications is this seal most useful?
A4: It is highly suitable for industrial machines, transmission units, automotive engine shafts, and other assemblies where high durability and oil resistance are required.

Q5: Is this seal suitable for dusty or contaminated environments?
A5: Yes, the RHSC double-lip design includes a dust lip that significantly improves resistance to contamination, making it effective in harsher environments.
