What is the difference between shielded (ZZ) and sealed (2RS) deep-groove ball bearings?

Shielded (ZZ) bearings, like these uxcell 6812ZZ, 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, the 6812ZZ has a 60mm bore, 78mm outer diameter and 10mm thickness. Measure your shaft diameter and housing bore, then select the bearing whose stated metric dimensions match exactly.

Are uxcell 6812ZZ bearings suitable for Indian industrial environments?

Yes, the double shielded design (ZZ) helps protect the lubricant from dust and moisture common in Indian industrial settings. The Chromium Steel construction also offers good durability. For extremely wet or corrosive environments, stainless steel bearings might be preferred, but these offer robust performance for general use.

What is the load capacity of these uxcell bearings?

These 6812ZZ bearings have a static load rating of 10600 Newtons and a dynamic load rating of 11500 Newtons. This indicates their ability to withstand significant forces, making them suitable for various industrial machinery and equipment.

Can I buy original uxcell bearings in India?

Yes, you can buy original uxcell bearings in India through crowcrowcrow. We import directly from authorized US retailers and brand partners, ensuring authenticity and quality. All customs duties and GST are included in the price, and delivery is tracked via ExpressBox.

What is the noise level of these bearings?

These uxcell 6812ZZ bearings have a Z2 noise level. This rating is generally suitable for most general-use applications where extreme quiet operation is not the primary requirement.

How do I maintain these deep-groove ball bearings?

These bearings come pre-lubricated and are double shielded to retain grease. For general use, they require minimal maintenance. If operating in very dusty or high-temperature conditions, periodic re-lubrication might be beneficial, but for most applications, they are designed for long service life without frequent intervention.

Why choose this product

Engineered for Industrial Precision

These uxcell 6812ZZ bearings are built with Chromium Steel (GCr15) for superior hardness and wear resistance. The double-shielded design ensures lubricant stays in and contaminants stay out, critical for maintaining performance in India's varied industrial environments. With ABEC 1 tolerance and Z2 noise levels, they are suitable for general-purpose machinery. Unlike some local alternatives that may offer inconsistent material grades or less robust shielding, these bearings provide a verifiable standard of quality and durability, ensuring your equipment runs smoothly and reliably.

Ideal for Machinery & Equipment

These bearings are perfect for applications like micro motors, small rotary motors, office equipment, and general industrial machinery. They are best suited for environments where moderate speeds and consistent loads are expected. Individuals seeking replacements for worn-out bearings in machinery or looking to upgrade existing components for better durability and lower maintenance will find these suitable. Those requiring extremely high-speed applications or specialized load capacities might need to explore different bearing types.

How to use

Confirm your existing bearing's inner diameter (60mm), outer diameter (78mm), and thickness (10mm) match the uxcell 6812ZZ specifications before removal. — Verify Dimensions
Carefully remove the old bearing from the housing and shaft using appropriate bearing puller tools to avoid damaging the equipment or the new bearing. — Remove Old Bearing
Gently press the new uxcell 6812ZZ bearing into the housing, ensuring it sits flush and square. Avoid applying excessive force directly to the shields or cage; press on the outer ring. — Install New Bearing
Rotate the shaft or component manually to check for smooth operation and any signs of binding. Reassemble the equipment and test under normal operating conditions. — Test Operation
