6915 Deep Groove Ball Bearing | Open, ZZ, 2RS Ultra-Thin Precision Bearings
The 6915 deep groove ball bearing is a heavy-duty ultra-thin precision component in the 6900 series, featuring upgraded thickened raceways and optimized rolling element arrangement for enhanced structural rigidity and reliable medium-load bearing capacity. Designed for ultra-compact, space-limited industrial installation environments, this single-row thin-wall bearing delivers stable low-friction rotation, superior dimensional consistency and excellent anti-fatigue performance. It supports long-term ultra-quiet, high-speed cyclic continuous operation, serving as a critical core rotary component for medium-sized miniaturized electromechanical equipment and industrial precision transmission systems. The 6915 series provides three standard industrial configurations: open type, 6915ZZ double metal shield type and 6915-2RS double rubber sealed type, with five industrial-grade materials to adapt to economical, sanitary, wear-resistant and corrosive complex working scenarios.
6915 Open / ZZ / 2RS Structural Features
6915 Open Type: The unsealed open structure enables unobstructed air circulation and efficient heat dissipation, effectively eliminating thermal accumulation during prolonged high-speed operation. It supports tool-free grease replenishment and effortless routine maintenance without generating extra rotational resistance. Ideal for clean, dry indoor workshops and fully enclosed precision equipment, it maintains stable running accuracy and consistent performance during long-cycle medium-load operation.
6915ZZ Double Metal Shields: Equipped with dual-sided non-contact steel shields, this premium dust-proof bearing effectively blocks fine dry dust, floating micro particles and tiny industrial debris. The non-contact protective design retains original high-speed precision and rotational smoothness with minimal friction loss. Featuring long-lasting durability and excellent cost performance, 6915ZZ bearings are widely applied in dry high-speed miniature motors, precision consumer electronics, automated micro components and compact industrial transmission systems.
6915-2RS Double Rubber Seals: This fully sealed variant adopts double-sided contact rubber seals to comprehensively isolate moisture, water splashes, oil mist and corrosive fine dust. It tightly locks internal lubricating grease to prevent leakage, oxidation and aging, realizing long-term maintenance-free operation. It stably adapts to humid, dusty and mildly harsh working conditions for outdoor and industrial high-precision electromechanical devices.
6915 Bearing Material Performance
Carbon Steel: High cost-performance standard industrial material with uniform hardness and stable anti-fatigue properties. It delivers dependable wear resistance and smooth high-speed rotation for conventional precision equipment, providing optimal cost efficiency for mass electronic and industrial batch applications.
304 Stainless Steel: Food-grade stainless steel with outstanding oxidation and rust resistance. It prevents surface corrosion and precision degradation in humid and open environments, ideal for food processing machinery, sanitary equipment and daily precision electromechanical devices.
316 Stainless Steel: Marine-grade corrosion-resistant material with strong tolerance to acid, alkali and salt spray. It withstands mild chemical corrosion and coastal high humidity, perfect for marine precision parts, sanitary instruments and chemical processing equipment.
420 Stainless Steel: High-toughness martensitic stainless steel balancing moderate corrosion resistance and high surface hardness. It features stable wear and impact resistance, maintaining accurate dimensional stability during long-term continuous high-speed operation.
440 Stainless Steel: Ultra-high hardness stainless steel with top-tier abrasion resistance and structural stability. It sustains precise, stable operation under severe wear and corrosive conditions, customized for high-end ultra-thin precision industrial equipment.
