Confirm your application requires bearings with a 4mm inner diameter, 8mm outer diameter, and 3mm thickness. Ensure compatibility with the shaft and housing before proceeding. — Verify Dimensions 2. Gently press the bearing onto the shaft or into the housing. Avoid applying excessive force or hammering, which can damage the bearing races or seals. — Install Carefully 3. Ensure the bearing rotates freely and smoothly without binding or excessive noise. The double seals are pre-lubricated for immediate use. — Check Rotation ## Product details | Field | Value | |---|---| | Inner Race/Outer Race Material | Chrome Steel (GCr15) | | Cage Material | Stamping Steel | | Seal Material | Nitrile Butadiene Rubber (Reinforced) | | Suitable For | Industrial equipment, micro motor, small rotary motor, office equipment | | Load Rating (Dynamic) | 336N | | Load Rating (Static) | 113N | | Cost per use | 10 pcs at ₹1,394 — ₹139 per bearing | | Shelf life after opening | 12M (typical for sealed bearings) | | Reapplication math | N/A (durables) | | Contraindications | Applications requiring extremely high speeds or specialized materials beyond chrome steel. | | Allergens / common irritants | Nitrile Butadiene Rubber (in seals) | | Brand | uxcell | | Model | MR84-2RS | | Seal Type | Double Sealed (2RS) | | Material | Chrome Steel (GCr15) | | Cage Material | Stamping Steel | | Inner Diameter | 4mm | | Outer Diameter | 8mm | | Thickness | 3mm | | Accuracy Class | P0 (ABEC-1) | | Noise Level | Z2 | | Number of Pack | 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 MR84-2RS has a 4mm inner diameter, 8mm outer diameter and 3mm thickness. Measure your shaft diameter and housing bore, then select the bearing whose stated metric dimensions match exactly. ### Are uxcell MR84-2RS ball bearings suitable for Indian industrial environments? Yes, the double-sealed Chrome Steel construction offers durability and protection against dust and moisture, making them suitable for various Indian industrial environments. They are designed for general use with low maintenance requirements. ### What is the load capacity of these bearings? The uxcell MR84-2RS bearings have a static load rating of 113 newtons and a dynamic load rating of 336 newtons, suitable for general industrial applications with moderate loads. ### Can I buy original uxcell ball bearings in India?
