Designed as unbalanced, single-acting helical coil spring seals that operate independently of the direction of rotation, Single Spring Unbalanced Seals offer versatile sealing solutions. These seals, driven by a helical coil spring, remain unbalanced and are conveniently mounted internally, simplifying the installation process. The rotary seal ring derives its motion directly from the shaft, ensuring a seamless and slippage-free operation that safeguards both the shaft and sleeve from fretting.

With the spring entirely shielded from the product, these seals prove highly practical for handling abrasive particles and solids in the media. Their inherent design enhances convenience, making them particularly suitable for applications where durability and ease of use are paramount.
