Features & Benefits

The slewing bearing consists of five essential components: the inner ring, which rotates; the outer ring, which remains stationary; rolling elements that facilitate movement; spacers for even distribution; and seals that protect against contaminants and retain lubrication.

The outer ring has excellent mechanical performance, with high strength and toughness. After quenching and tempering (Q+T), it exhibits fatigue resistance, impact resistance, and excellent low-temperature impact toughness.
The inner ring has excellent mechanical performance, with high strength and toughness. After quenching and tempering (Q+T), it exhibits fatigue resistance, impact resistance, and excellent low-temperature impact toughness.
Rollers and balls are both types of rolling elements, which are the most crucial components of rotary support bearings and the most commonly used rolling elements in the bearing industry.
It is located between the outer raceway, inner raceway, and rollers/balls of the bearing. It is a isolator block that serves as a cage.
Its role serves two purposes: Firstly, to prevent the loss of lubricating grease or oil inside the bearing, ensuring proper lubrication. Secondly, to shield the bearing from external dust or harmful gases, thus preventing damage.
To ensure the smooth operation of the bearing, it is necessary to inject lubricating grease or oil between the inner and outer rings of the bearing. The function of lubricating grease or oil is to reduce friction coefficient and wear, minimize bearing heat and friction losses, and enhance bearing lifespan.
