693 Bearing | Open / ZZ / RS Seals | High-Precision Materials And Industrial Application
The 693 bearing is a thin-wall deep groove ball bearing with enlarged micro size, designed for compact mechanical assembly systems. It features low vibration, consistent rotational accuracy and outstanding load stability during continuous cyclic operation. Available in Open, ZZ and RS sealing configurations and multiple corrosion-resistant material grades, this versatile micro bearing caters to high-precision and multi-environment industrial assembly scenarios.
693 Bearing Different Seal Types
693 Open Bearing: Adopts fully open structure with unobstructed heat dissipation and zero rotational resistance. It supports long-duration high-speed cycling and flexible lubrication maintenance. Suitable for indoor dust-free industrial environments, widely used in precision automation modules, micro transmission shafts and laboratory testing machinery.
693ZZ Bearing (Double Metal Shields): Designed with double-sided non-contact metal shields to isolate dry dust, fine particles and airborne impurities effectively. It retains stable high-speed performance without friction loss, featuring excellent thermal stability. Ideal for dry working conditions such as miniature drive motors, precision detection instruments and intelligent terminal equipment.
693RS Bearing (Double Rubber Seals): Equipped with double-sided contact rubber sealing rings for enhanced waterproof, dustproof and moisture-proof protection. It resists external environmental interference and realizes long-term maintenance-free operation, perfectly suited for humid, dusty and variable scenarios like outdoor monitoring devices, smart automation accessories and household precision electromechanics.
693 Bearing Material Features And Industrial Applications
Bearing Steel: Premium industrial base material with strong compression resistance, excellent wear resistance and stable dynamic load performance. With high cost-performance and long service life, it is widely used in general machinery assembly, micro motor accessories and conventional precision transmission equipment.
304 Stainless Steel: Offers reliable oxidation resistance and stable mechanical rigidity, effectively resisting mild humid rust and daily abrasion. It is an economical choice for civilian electronic devices, light industrial assembly parts and ordinary low-load outdoor machinery.
420 Stainless Steel: Boasts high hardness, excellent toughness and weak corrosion resistance, maintaining stable precision operation under long-term light load. Mainly applied in optical precision equipment, portable medical devices and high-end intelligent micro machinery systems.
440 Stainless Steel: Features ultra-high hardness and superior anti-wear performance, with strong tolerance to medium corrosive environments. It is widely adopted in industrial precision fittings, hydraulic auxiliary components and high-stability mechanical transmission systems.
316 Stainless Steel: Provides exceptional acid-base, salt fog and high-temperature oxidation resistance, adapting to harsh corrosive working conditions. It is the preferred material for food processing machinery, marine equipment parts, chemical instruments and medical sanitary facilities.
Product Advantages: The 693 thin-wall bearing offers diversified sealing and material solutions, featuring high rotational precision, low vibration, stable operation and strong environmental adaptability. It covers light industry, automation, medical sanitation, marine and chemical fields, meeting multi-scenario high-precision assembly and transmission requirements.
