6901Z Thin Section Bearings

The 6901Z thin section bearings are a small sealed bearing with 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. Its small structure, low friction, economical and practical, widely used in micro motors, consumer electronics, precision instruments and household appliances, especially for high-speed rotating parts in dry and low-pollution environments.

Parameter

Core Features

Single-sided dust protection (Z type):

The metal dust cover is fixed to the outer ring to prevent large dust particles from intruding and extend the lubrication life.

Limitations: Not waterproof, suitable for dry and low-humidity environments (such as indoor equipment).

Standard material: high carbon chromium steel (GCr15), surface hardness HRC 58-62, excellent wear resistance.

Typical application areas

Consumer electronics:

Drone gimbal motor, smart watch vibration motor, camera focus module.

Case: TWS headset charging case opening and closing bearing, requiring ultra-thin design and silent operation.

Medical equipment:

Dental drill spindle, insulin pump micro motor, requiring sterility and low noise.

Office equipment:

Laser printer drum shaft, scanner guide rail, adapted to high speed and low maintenance requirements.

Household appliances:

Electric shaver motor, air fryer fan, high temperature resistant intermittent operation.

Industrial precision instruments:

Optical platform adjustment mechanism, semiconductor testing equipment turntable, requiring high precision and dustproof.

Installation and maintenance

Installation points:

1. Miniaturization operation:

- Use tweezers or vacuum suction pen to install to avoid hand grease contamination.

2. Anti-static measures:

- When used in electronic equipment, it is necessary to ground and eliminate static electricity before installation to prevent breakdown of microcircuits.

Maintenance strategy:

Maintenance-free design: Most micro-devices are disposable packages and do not require additional lubrication.

Failure detection:

Bearings need to be replaced when the speed decreases or the vibration increases
