6902Z Thin Section Bearings

The 6902Z thin section bearings are a small sealed bearing in the deep groove ball bearing series. It adopts a single-sided metal dust cover (Z type) and a thin-walled lightweight design. It is optimized for medium and low load scenarios with compact space and basic dust protection. It has a compact structure, low friction, and is economical and practical. It is widely used in micro motors, precision instruments, household appliances, and consumer electronics. It is especially suitable for high-speed rotating parts in dry and low-pollution environments, and has both high cost performance and reliability.

Parameter

Core Features

Ultra-thin and compact design:

The outer diameter is 28mm, the width is only 7mm, the wall thickness is optimized, and it is suitable for micro devices (such as drone motors and smart wearable devices).

The weight is about 18% lighter than that of standard bearings, which reduces inertial resistance and improves dynamic response performance.

Single-sided dust protection (Z type):

The metal dust cover (galvanized steel plate) is fixed to the outer ring to prevent large dust particles from invading and extend the lubrication life.

| **Inner diameter (d)** | 15 mm |

| **Outer diameter (D)** | 28 mm |

| **Width (B)** | 7 mm |

Typical application areas

Office equipment:

Laser printer drive shaft, scanner guide rail, suitable for high speed and low maintenance requirements.

Household appliances:

Electric toothbrush motor, air purifier fan, resistant to intermittent high-speed operation.

Industrial instruments:

Optical platform adjustment mechanism, semiconductor detection equipment turntable, high precision and dustproof are required.

Bearing preservation

Bearings are precise parts. In order to maintain the accuracy and reliability of bearings, they must be handled carefully during operation, especially to keep the bearings clean and avoid strong collisions and rust.

The 6902Z thin section bearings produced by the company are all attached with rust inhibitors on the surface and should be stored at room temperature with a relative humidity below 60%.
