DAC152TN9 Automotive Steering System Bearings

DAC152TN9 Automotive Steering System Bearings

⚙️Product description:

DAC152TN9 is a commonly used bearing in automotive steering systems. As a key component of the automotive steering system, it is mainly responsible for supporting the rotation of the steering shaft or steering gears, ensuring the smoothness and accuracy of the steering operation, converting the rotational motion of the steering wheel into linear motion of the rack (in gear-rack type steering systems), thereby enabling the wheels to turn.

Material configuration: The raceways and rolling elements are made of chrome steel (the mainstream bearing steel material in the industry), featuring high hardness (HRC 58-62) and fatigue resistance; the cage is made of glass fiber reinforced nylon PA66 (indicated by suffix TN9), combining lightweight and friction resistance properties.

Performance indicators: The static radial load is approximately 800-1000N, the dynamic radial load can reach over 1800N, the maximum rotational speed is not less than 8000r/min, meeting the rotational speed requirements of the steering gear under normal working conditions.

⚙️Performance Advantages:

Silent optimization design:

The steering gear bearings are precisely matched with the rolling elements through nylon cages, reducing metal friction noise during operation and meeting the quietness requirements of the vehicle steering system.

Adaptability to working conditions:

It adopts an open structure (without sealing design) and needs to be used in conjunction with steering machine-specific lubricating grease. It can operate stably within a temperature range of -30℃ to 120℃, resisting the start-stop impact and continuous load of the steering system.

Installation ease：

The bearings adopt a cylindrical inner hole design, combined with shoulder positioning or locking devices, which simplifies the assembly process of the steering gear shaft system and reduces maintenance difficulty.

⚙️Precautions:

1. Keep clean	2. Use with caution	3. appropriate tool	4. Hot-loading	5. Be careful of rust
Dust will have a bad effect on the bearing, so keep the surrounding clean.	Strong impact during use can easily cause scratches and indentations.	Avoid replacing existing tools, and use appropriate tools.	Bearings are precision parts, so hot installation is recommended.	Sweat on your hands during operation will cause rust, so it is best to wear gloves.
