Reliable Bearings for Industrial Equipment
uxcell MR84-2RS deep groove ball bearings provide reliable performance for various industrial applications. These bearings feature a 4mm inner diameter, 8mm outer diameter, and 3mm thickness, constructed from durable Chrome Steel (GCr15) with double seals to retain lubricant. They are suitable for general use, offering resistance to heavy loads and a Z2 noise level. Imported from authorized US retailers and authorized brand partners, these bearings ensure quality for your machinery.
With a static load rating of 113N and dynamic load rating of 336N, these ABEC-1 (P0) rated bearings are designed for applications with low Mohs hardness requirements. The double-sealed design protects the internal lubricant from contamination, extending the bearing's lifespan and reducing maintenance needs, which is crucial for equipment operating in India's varied environmental conditions.
These bearings are cost-effective and require little maintenance, making them suitable for micro motors, small rotary motors, and office equipment. All customs duties and GST are included in the listed price, with delivery via ExpressBox tracked shipping to your pincode.

Reliable Performance for Industrial Needs
uxcell MR84-2RS deep groove ball bearings are engineered for consistent performance. Their Chrome Steel construction and double-sealed design provide protection against contaminants, vital for machinery operating in India's diverse climates. The ABEC-1 (P0) accuracy and Z2 noise level make them suitable for general industrial use, ensuring your equipment runs smoothly without excessive wear or noise. Imported directly from authorized US retailers and authorized brand partners, these bearings offer a dependable alternative to local options, backed by our commitment to quality and transparent pricing with all duties included.
Ideal for Small Motors & Equipment
These bearings are best suited for applications requiring small, precise components like micro motors, small rotary motors, and office equipment. They are ideal for users who need reliable, low-maintenance bearings for general industrial tasks. Skip if your application demands extremely high speeds or specialized materials beyond chrome steel, as these are designed for cost-effectiveness and general durability rather than extreme performance conditions.
