Sealing structure

The outer ring of the sealing structure features a metal skeleton, while the inner side is equipped with a rubber lip. A spring is fitted in the middle. The multi-lip design not only prevents external mud, water, and dust from entering but also effectively seals against internal grease leakage. The outer ring of the sealing structure consists of a metal skeleton integrated with rubber through vulcanization. The inner ring is a rigid stainless steel ring, and the rubber lip area is filled with grease. This design is suitable for sealing rotating components while maintaining low torque.

Product Description

Product Introduction

The outer ring of the sealing structure features a metal skeleton, while the inner side is equipped with a rubber lip. A spring is fitted in the middle. The multi-lip design not only prevents external mud, water, and dust from entering but also effectively seals against internal grease leakage.
The outer ring of the sealing structure consists of a metal skeleton integrated with rubber through vulcanization. The inner ring is a rigid stainless steel ring, and the rubber lip area is filled with grease. This design is suitable for sealing rotating components while maintaining low torque.

Technical Parameters

Mud durability: ≥400 h;
High-speed fat removal: ≤0.2 g;
Wear: ≥100 h;

Torque: ≤0.3 N.m;
Single-unit sealing: ≥400 hours.

Product Advantages

The spring-loaded design increases the radial force of the sealing lip against the shaft and compensates for the elasticity of the rubber. When combined with a dust cover, this forms a labyrinth seal, resulting in even better sealing performance.

The sealing structure adopts a combination of inner and outer rings, which not only ensures an effective seal but also reduces the relative torque.

Product Use

The oil seal is used in maintenance-free Universal joint and ultimately in automotive propeller shaft assemblies.

The sealing assembly is used for automotive wheel hub unit bearings.
