Maintenance free by reducing grease loss

Product catalog summary

Overview: The document details the NB Reverse-Seal, a maintenance-free seal unit designed to reduce grease loss. It consists of a reverse plate, seal, and cover, with an additional side-seal oriented in reverse to the block.

Specifications: The Reverse-Seal is available for sizes 15 to 25 of standard SGL types. The block total length varies by type, with specific dimensions provided for each model (e.g., SGL-HTEX, SGL-HYE, etc.).

Advantages: The Reverse-Seal creates a "Grease Pocket" between two seals, minimizing grease leakage and loss, thus making it maintenance-free. It is suitable for food processing applications when combined with stainless steel guide SGLS type and NSF H1 certified grease.

Performance Data: Grease dry-up and leakage tests show significant improvements with the Reverse-Seal. For instance, the SGL25TF model with the Reverse-Seal achieved a travel distance of 4,500 km compared to 315 km for the standard model.
