The CR08-B profile is a high-reliability rotary shaft seal specifically engineered for grease-based applications in drive systems and pumps where a springless design is required. This interference-fit seal operates optimally in non-pressurized (0 Bar / 0 Mpa & 0 PSI) environments, providing an exceptional static seal even in split housings or bores with increased surface roughness. Its flexible sealing lip is designed to compensate for shaft-to-bore misalignment, ensuring low breakaway torque and a consistent barrier against environmental contamination.

• Superior Static Sealing: Interference fit ensures reliable performance in split housings and surfaces with high roughness or thermal variance.
• Misalignment Tolerance: Flexible lip design effectively manages shaft run-out and bore misalignment, maintaining integrity during dynamic rotation.
• Advanced Production: Manufactured via Computer-Controlled Turning, offering Zero-Tooling Lead Times for high-precision custom batches.
• Heavy-Duty Reliability: Robust sealing solutions for 3000mm large-bore hydraulics and high-performance large seals for extreme heavy machinery.
• Maintenance Friendly: Simple installation and removal process that protects the housing bore, reducing long-term equipment downtime.
The CR08-B is a versatile springless seal offering a secure press-fit in open housings through axial clamping, making it ideal for applications with different thermal expansion rates. It functions effectively as a primary grease seal or as a secondary protective element to keep dust and dirt away from main sealing components. Its design allows for simple mounting and dismounting without risking damage to the housing bore. This profile is particularly favored in scenarios where metal springs are restricted, providing a durable, low-friction solution for modern rotating machinery.
