Need a Reliable 61902 Deep Groove Ball Bearing? Avoid Common Pitfalls
Many buyers struggle with mismatched bearing dimensions causing installation delays, or low-quality bearings failing prematurely with excessive noise and vibration. Sourcing from multiple suppliers for different brands only adds complexity to your procurement process.
Built for Consistent Performance in Demanding Applications
Our 61902 deep groove ball bearing addresses these challenges with ISO 9001-certified manufacturing processes and strict quality control. Available in open (61902), single shielded (61902-Z), and double shielded (61902-2Z) configurations, it fits seamlessly into automotive electric motors, conveyor systems, and hydraulic pumps. With access to international brands like NTN and extensive inventory, we streamline your sourcing needs.
Optimal Performance in Radial Load Scenarios
This single-row radial bearing excels in applications with pure radial loads, operating at moderate speeds. The 0° contact angle ensures efficient load distribution, while the bearing steel construction provides durability in temperatures ranging from -30°C to 120°C. Its compact 15x28x7mm dimensions make it ideal for space-constrained industrial equipment where reliable rotation is critical.
Key Engineering Features Explained
The bearing steel material offers excellent hardness and wear resistance, essential for withstanding continuous operation. Shielded variants (Z/2Z) protect internal components from contaminants, reducing maintenance needs in dusty environments. Precise 15mm bore diameter and 28mm outer diameter ensure interchangeability with major international standards, simplifying replacement. The 7mm width balances load capacity and space efficiency, making it suitable for both light and medium-duty applications.
Why Correct Bearing Selection Lowers Total Cost
Choosing the right deep groove ball bearing directly impacts equipment uptime and maintenance expenses. Inferior bearings with substandard material hardness often fail within months, causing unplanned downtime and costly repairs. Our bearings undergo rigorous dimension and hardness testing, ensuring they meet original equipment specifications. By selecting the appropriate configuration (open or shielded) for your environment, you reduce lubrication requirements and extend service life, lowering long-term operational costs.
Quality You Can Rely On
Our production and inspection processes comply with ISO 9001 standards, covering raw material verification through final dimensional and hardness testing. Each bearing is packed to prevent damage during transport and comes with a manufacturer-backed warranty against defects. We maintain extensive inventory across multiple international brands, supporting quick delivery for both small and large orders. For specialized requirements, OEM/ODM customization options are available to match your exact specifications.
Packaging & Shipping
- Standard industrial packaging to ensure product integrity during transit
- Readily available from stock for prompt dispatch
