MR62 Bearing | Open / ZZ / RS Seals | Compact Metric Micro Bearings for Small-Scale Mechanical Assembly
The MR62 bearing is a compact metric micro deep groove ball bearing developed for miniature assembly systems and limited-structure mechanical equipment. With optimized inner bore design, lightweight build and consistent low-friction operation, this micro bearing delivers reliable dynamic stability during continuous low-load operation. Available in three mainstream sealing variants including Open, ZZ and RS, and configurable with five industrial-grade metal materials, MR62 bearings provide targeted anti-wear, anti-dust, waterproof and anti-corrosion solutions for diverse small precision mechanical applications.
MR62 Bearing Seal Type Features And Application Environments
MR62 Open Bearing: Features a uncovered open structure with unobstructed heat dissipation and minimal running resistance. It supports long-duration high-speed rotation and easy on-site lubrication refilling, greatly simplifying daily maintenance procedures. Ideal for clean, dry indoor working conditions, widely used in precision micro transmission structures, tiny instrument rotating parts and desktop experimental precision equipment.
MR62ZZ Bearing (Double Metal Shields): Equipped with dual non-contact metal shielding plates on both sides, effectively blocking dry fine dust, floating industrial particles and tiny debris. The non-contact structure creates no extra operating resistance, retaining stable rotation accuracy and excellent heat-resistant aging performance. Perfect for dry indoor working scenarios such as micro fan motors, precision sensing equipment and portable intelligent electronic products.
MR62RS Bearing (Double Rubber Seals): Adopts double-sided contact rubber sealing rings with excellent fitting tightness, forming a reliable protective barrier against moisture, water splash and mixed dust pollution. It effectively avoids internal grease failure and particle accumulation, realizing long-term maintenance-free operation. Suitable for complex environments including semi-humid workshops, small outdoor intelligent devices and automated miniature assembly accessories.
MR62 Bearing Material Characteristics And Industrial Application Fields
Bearing Steel: Standard high-strength bearing alloy with outstanding surface hardness, excellent anti-wear performance and stable micro-load bearing capacity. It features high structural durability and cost-effectiveness, serving as the preferred conventional material for small motors, daily miniature machinery and general precision transmission components.
304 Stainless Steel: Offers excellent atmospheric oxidation resistance and daily rust-proof capability, maintaining stable mechanical performance in conventional humid and ventilated environments. It is an economical practical material for consumer electronics, light industrial miniature fittings and ordinary low-load civilian mechanical equipment.
420 Stainless Steel: Balances high hardness and mechanical toughness with slight chemical corrosion resistance, maintaining smooth and accurate rotation under long-term intermittent operation. Mainly applied in miniature medical auxiliary equipment, portable optical instruments and compact high-end intelligent machinery.
440 Stainless Steel: Possesses ultra-high hardness and superior abrasion resistance, with strong adaptability to medium corrosive working environments. It ensures long-term stable operation for precision automation micro components, miniature transmission accessories and industrial precision matching parts.
316 Stainless Steel: Features exceptional salt spray resistance, acid and alkali corrosion resistance, adapting to harsh corrosive working conditions. It is widely used in marine miniature accessories, food processing precision equipment, chemical testing instruments and medical sanitary devices.
Product Core Advantages: The MR62 compact micro bearing supports diversified sealing and material customization, featuring flexible installation, steady low-friction operation, low noise and strong environmental adaptability. It covers consumer electronics, industrial automation, precision instrumentation, medical health, food processing and marine industries, meeting diverse miniature precision assembly and transmission requirements.
