16002 Bearing | Open / ZZ / RS Seals | High Durability Multi-Material Micro Bearing

The 16002 bearing is a robust micro deep groove ball bearing with optimized thin-wall structure, designed for space-constrained mechanical assemblies and light-duty transmission systems. It features consistent rotational smoothness, low operational torque and outstanding dimensional stability during long-cycle operation. Offered in three distinct sealing configurations and five industrial-grade materials, this multi-functional bearing delivers reliable performance for commercial, precision and corrosive environment applications.

16002 Bearing Seal Type Performance

16002 Open Bearing: No shield and seal structure achieves maximum air permeability and ultra-low running torque. It facilitates quick heat dissipation and easy regular lubrication replenishment, supporting prolonged high-speed rotation. Suitable for dry, clean laboratory and industrial indoor environments, ideal for precision positioning modules, micro transmission shafts and high-speed electronic mechanical systems.

16002ZZ Bearing (Double Metal Shields): Features dual non-contact metal protective covers that effectively isolate dry dust, fine industrial particles and floating debris. Without increasing rotational friction, it maintains stable high-speed precision and excellent heat aging resistance, perfectly suited for dry working scenarios such as small industrial motors, precision detection instruments and intelligent terminal equipment.

16002RS Bearing (Double Rubber Seals): Adopts double-sided contact rubber seal rings with enhanced waterproof and anti-fouling properties. It effectively resists moisture penetration, dust accumulation and minor pollutant erosion, realizing long-term maintenance-free operation. Widely applicable to humid workshops, outdoor precision devices and automated mechanical accessory systems with complex ambient conditions.

16002 Bearing Material Traits And Industrial Applications

Bearing Steel: High-performance bearing base material with exceptional hardness, strong wear resistance and stable dynamic load capacity. Featuring durable service life and high cost-effectiveness, it is the preferred option for general mechanical transmission, micro motor accessories and conventional industrial precision equipment.

304 Stainless Steel: Possesses excellent anti-oxidation and daily rust-proof capabilities, maintaining stable mechanical performance in normal humid and atmospheric environments. It serves as a cost-efficient solution for consumer electronic parts, light industrial machinery and general low-load outdoor equipment.
