Ball bearing
Contact-type sealed bearings come equipped with integral sealing rings that are in direct contact with the inner race of the bearing, leaving no gap between them. Because this sealing design requires the sealing element to be in direct contact with the mating component, contact-type seals for bearings include: felt seals, lip seals, labyrinth seals, and skeleton seals, among others.

Product Description
Product Introduction
Contact-type sealed bearings come equipped with integral sealing rings that are in direct contact with the inner race of the bearing, leaving no gap between them. Because this sealing design requires the sealing element to be in direct contact with the mating component, contact-type seals for bearings include: felt seals, lip seals, labyrinth seals, and skeleton seals, among others.
Technical Parameters
Accuracy class: P6;
Vibration level: V3 Z3;
Lifetime indicator: ≥5L10;
Low temperature rise: <35℃.
Product Advantages
Contact seals tend to suffer from wear and tear during rotation, generating frictional heat that can degrade sealing performance. Our company has developed a lightweight contact seal through optimized design, which boosts the maximum rotational speed by more than 30% and keeps the temperature rise below 35°C.
Product Use
The sealed bearing is a mechanical component widely used in industrial equipment. It prevents lubricant leakage and the ingress of external contaminants—such as dust and moisture—into the bearing interior, thereby ensuring the bearing’s smooth operation and extending its service life. This project is applied to the transmission system of unmanned helicopters.
