Super Precision Cylindrical Roller Bearings from Schaeffler.
N10 and NN30 super precision cylindrical roller bearings in X-life quality
The performance capacity and operating life of our single-row N10 cylindrical roller bearings and double-row NN30 cylindrical roller bearings have significant greater performance capacity and longer operating life compared in the market. Comprehensive tests carried out on Schaeffler test rigs clearly show that our bearings are the benchmark and deliver the highest limiting speeds, the least heat generation, and the lowest running temperatures. This means an increase in both operating life and operational reliability together with lower operating costs.
Proven to be better compared in the market
- Up to 65% longer operating life
- Up to 35% increase in limiting speeds
- Up to 19% higher dynamic load ratings
- Running temperatures reduced by up to 12 K
- Longer grease operating life
- Lower levels of friction and quieter running
- Lubrication groove and lubrication bore omitted as a standard feature
- Can be used as a 1-to-1 replacement for competitors’ products (particularly N10)
The reasons for this superior performance lies in the groundbreaking design, optimized manufacturing methods, and a window cage made from PPA high-performance polyamide (polyphthalamide, suffix TVP).
The bearings offer machine designers a larger degree of freedom during product development. Machine operators, on the other hand, can change over from our main competitors’ bearings to our bearings without any problems. The mounting dimensions of all the common sizes are now identical thanks to the adaptation of the enveloping circle to match non-Schaeffler bearings.
Increased performance and new design options
Optimized surfaces and an improved internal construction open up a range of new bearing design options. Depending on requirements, design engineers can place the focus on a higher load carrying capacity or a longer operating life. The PPA window cage additionally ensures lower friction, resulting in reduced heat generation and enabling significantly higher limiting speeds up to the speed levels of axial bearings (BAX bearings). This allows significantly improved designs to be achieved, particularly when the bearings are used in conjunction with high-speed axial bearings.
Conclusion
Our cylindrical roller bearings are one of the best-performing and most durable cylindrical roller bearings on the market. Schaeffler offer new design options, which can simply replace non-Schaeffler bearings, and are available now.
