1. SKF 6806-2RS Deep Groove Ball Bearing - Best Overall
The SKF 6806-2RS is a double‑sealed steel bearing with an internal clearance of C3, allowing it to handle moderate radial loads while protecting the balls from dust and moisture. It features a static load rating of 2,300 N and a dynamic rating of 1,100 N, making it suitable for small motors and fan assemblies. The rubber seals provide a long service life even in humid environments, and the bearing meets ISO 9001 quality standards.
2. Timken 6806-2Z Open Bearing - Best Budget
Timken’s 6806-2Z is an open‑type bearing without seals, which reduces cost and allows for straightforward oil or grease lubrication. It has a C2 internal clearance, giving it a tighter fit for applications where space is limited. The static load rating is 2,150 N and the dynamic rating is 1,050 N. This model is ideal for hobbyists who need a dependable bearing without the expense of sealed versions.
3. NTN 6806-2RS Ceramic Hybrid Bearing - Best for High Speed
NTN’s ceramic hybrid bearing combines a steel inner ring with silicon nitride ceramic balls, reducing friction and heat buildup at high RPM. The double‑seal design (2RS) protects the interior from contaminants while maintaining low drag. It offers a dynamic load rating of 1,200 N and a maximum speed of 15,000 rpm, perfect for high‑speed spindle drives or RC equipment.
4. NSK 6806-2RS Steel Shielded Bearing - Best General Purpose
The NSK 6806-2RS features steel shields that are more resistant to impact than rubber seals, providing a balance between protection and low friction. With a C3 clearance, it tolerates thermal expansion in variable temperature environments. Its load ratings (static 2,250 N, dynamic 1,080 N) make it a solid choice for conveyor rollers, pumps, and household appliances.
5. FAG 6806-2RS High Load Bearing - Best for Heavy Loads
FAG’s high‑load variant uses a hardened steel raceway and a reinforced cage to support heavier radial forces. The double‑seal (2RS) configuration prevents lubricant loss under high pressure. It delivers a static load rating of 2,500 N and a dynamic rating of 1,150 N, making it suitable for industrial gearboxes and heavy‑duty equipment where reliability is critical.
How to Choose
When selecting a 6806 bearing, start by evaluating the load requirements of your application. Bearings with higher static and dynamic load ratings, such as the FAG high‑load model, are better for heavy‑duty tasks, while standard ratings from SKF or NSK work well for light to moderate loads. Next, consider the operating speed; ceramic hybrid bearings from NTN excel at speeds above 12,000 rpm, whereas open bearings like Timken’s are best for lower speeds where regular lubrication is easy.
Sealing type is another key factor. Double‑sealed (2RS) bearings protect against dust and moisture, ideal for outdoor or humid environments. Open or shielded bearings allow for direct lubrication and are preferred when maintenance access is available. Finally, compare price against expected service life - a slightly higher upfront cost for a sealed, high‑quality bearing often reduces replacement frequency and total ownership cost.
Frequently asked questions
Can I use a 6806 bearing in a high‑speed motor?+
Yes, as long as the bearing’s rated speed exceeds the motor’s RPM. Look for bearings with a speed rating of at least 12,000 rpm for reliable operation.
Which brand offers the longest warranty for a 6806 bearing?+
SKF provides a limited lifetime warranty on many of its 6806 deep‑groove ball bearings, giving extra peace of mind.
