Double Lip Seals for Slide Bush

Product catalog summary

Introduction
The document discusses the SM ZZ16 G Slide Bush with a Doublelip-seal Z Option, designed to reduce grease leakage and promote ecological benefits through grease saving.

Structure and Part Number
The slide bush is available in various types including standard, long, double-wide, and flange types. The part numbers range from SM(S)6 to 30 and TRF6 to 30. The ZZ option is applicable to these types, providing a doublelip-seal feature.

Doublelip-Seal Mechanism
The doublelip-seal consists of an outside lip-seal to prevent foreign particles from entering and an inside lip-seal to prevent grease leakage. This design increases seal resistance.

Advantages
The doublelip-seal offers enhanced protection against grease leakage compared to standard seals, as demonstrated in grease-leak comparison tests.

Grease-Leak Comparison Test
Tests conducted under specific conditions (horizontal axis, no load, maximum speed of 60m/min, stroke of 300mm) show reduced grease leakage in models with doublelip-seals compared to those with standard seals.

NB Corporation of America and its regional offices in the USA, Europe, and Japan provide contact details for further inquiries.
