Imported from USA, duties included, delivered within 6-8 days. ## Highlights - Durable Chrome Steel Construction — Made from GCr15 chrome steel, these bearings offer excellent durability and resistance to heavy loads, ensuring a longer lifespan in demanding industrial applications. - Double Sealed for Protection — The 2RS designation means both sides are sealed with rubber, effectively retaining lubricant and preventing dust and debris ingress, crucial for maintaining performance in Indian environments. - Precise Dimensions for Fit — With an 8mm inner diameter, 12mm outer diameter, and 3.5mm thickness, these bearings offer precise metric sizing for compatibility with various shafts and housings. - Cost-Effective Industrial Solution — These bearings provide a cost-effective solution for general industrial use, requiring minimal maintenance and offering reliable performance for micro motors and office equipment. ## Key features - MR128-2RS (I.D.=8mm, O.D.=12mm, Thickness=3.5mm) - mr128-2rs bearings are sealed on BOTH SIDES to keep lubricant in - Made from Chrome Steel (GCr15), durability and resistance to under heavy loads - ABEC Tolerance 1 (P0), Z2 Noise Level for most general use - Static load rating of 219 newtons and dynamic load rating of 462 newtons ## Why choose this product **Engineered for Reliability** — uxcell MR128-2RS bearings are built with chrome steel for robust performance and resistance to wear. The double-sealed design ensures lubricant stays in and contaminants stay out, a critical factor for longevity in India's varied climate. They are rated for specific load capacities (static 219N, dynamic 462N) and normal accuracy (ABEC-1, Z2 noise), making them suitable for general industrial applications where consistent performance is key. Imported directly from authorized US retailers, these bearings offer a reliable alternative to local options, ensuring you receive a product built to international standards. **Ideal for Small Motors & Equipment** — These bearings are best suited for applications like micro motors, small rotary motors, and office equipment where precise, low-maintenance rotation is needed. They are ideal for users who require specific metric dimensions (8x12x3.5mm) and a double-sealed design to protect against dust and moisture. Users needing high-speed applications or extremely high load capacities might consider shielded bearings or larger models. For general industrial tasks requiring reliable radial and axial load support, these bearings are a practical choice. ## How to use 1. Confirm the required inner diameter (8mm), outer diameter (12mm), and thickness (3.5mm) precisely match your shaft and housing specifications before installation. — Verify Dimensions 2. Ensure the shaft and housing bore are clean and free from debris or old lubricant. A clean surface is essential for proper bearing seating and performance. — Clean Mounting Area 3. Carefully press the bearing onto the shaft or into the housing. Apply force evenly to the outer ring when pressing into the housing, or to the inner ring when pressing onto the shaft, to avoid damaging the bearing. — Install Bearing 4. After installation, gently rotate the bearing by hand to ensure smooth operation. Listen for any unusual noises or resistance, which may indicate improper installation. — Check Rotation ## Product details | Field | Value | |---|---| | Inner/Outer Race Material | Chrome Steel (GCr15) | | Seal Material | Nitrile Butadiene Rubber (NBR) | | Cage Material | Stamping Steel | | Suitable For | Industrial equipment, micro motors, small rotary motors, office equipment | | Load Type | Radial and Axial loads in both directions | | Lubricant Type | Oil | | Cost per use | 10 bearings at ₹1,444 — ₹144 per bearing | | Shelf life after opening | 12M (standard for pre-lubricated bearings) | | Reapplication math | N/A (sealed bearings are pre-lubricated for life) | | Contraindications | Not suitable for extremely high speeds or very heavy loads beyond specified ratings; not for use in highly corrosive environments without additional protection. | | Allergens / common irritants | Nitrile Butadiene Rubber (NBR) in seals | | Brand | uxcell | | Model Number | MR128-2RS | | Seal Type | Double Sealed (2RS) | | Inner Diameter (ID) | 8mm | | Outer Diameter (OD) | 12mm | | Thickness (Bore) | 3.5mm | | Material | Chrome Steel (GCr15) | | Cage Material | Stamping Steel | | Accuracy Class | P0 (ABEC-1) | | Noise Level | Z2 | | Pack Quantity | 10 Pcs | | Country of Origin | Not stated by manufacturer — US retail version, sourced from authorized US retailers | ## Frequently asked questions ### What is the difference between shielded (ZZ) and sealed (2RS) deep-groove ball bearings? Shielded (ZZ) bearings use metal shields that retain grease and block larger debris while allowing higher speeds. Sealed (2RS) bearings use rubber contact seals that give better protection against fine dust and moisture, which suits dusty or humid Indian conditions. Choose based on your speed and contamination needs. ### How do I know which deep-groove bearing size I need? Match the ISO designation, which encodes the dimensions — for example a 6203 has a 17mm bore, 40mm outer diameter and 12mm width. Measure your shaft diameter and housing bore, then select the bearing whose stated metric dimensions match exactly. ### Are these uxcell bearings suitable for Indian industrial environments? Yes, the double-sealed (2RS) design with chrome steel construction offers good resistance to dust and moisture, making them suitable for many Indian industrial environments. For extremely humid or corrosive conditions, stainless steel bearings might be preferred, but these offer a durable, cost-effective solution for general use. ### What is the load rating for these MR128-2RS bearings? These bearings have a static load rating of 219 newtons and a dynamic load rating of 462 newtons. This makes them suitable for moderate loads in applications like micro motors and office equipment. ### How to choose hardware_bearing for Indian buyers? When choosing hardware bearings for India, consider the environment. Double-sealed bearings (like these 2RS models) are recommended for protection against dust and humidity. Verify the metric dimensions (bore, OD, thickness) precisely match your application. Ensure the load ratings are adequate for your intended use. Imported bearings from authorized US retailers offer consistent quality. ### Can I use these bearings for high-speed applications? These MR128-2RS bearings are designed for normal accuracy and general use with a Z2 noise level. While they have a high-limit speed, they are not specifically designed for extremely high-speed applications. Shielded bearings (Z/ZZ) typically offer higher speed capabilities than sealed bearings. ### What is the best hardware_bearing for general use? For general industrial use, deep groove ball bearings with double seals (like these MR128-2RS) made from chrome steel are a good choice. They offer a balance of durability, protection from contaminants, and cost-effectiveness. Ensure the dimensions and load ratings match your specific needs. ## Compliance No product-specific compliance warnings identified.
