RNA Needle Roller Bearing with cylindrical rollers that are small in diameter. In spite of their low cross section,
needle roller bearing have a high load carrying capacity and are therefore extremely suitable for bearing
arrangements where radial space is limited.supplies needle roller bearing in different designs and a wide range
of sizes, which are appropriate for different applications.
RNA Needle Roller Bearing Advantage
- Smaller cross-section leading to greated rigidity,higher load-carrying capacity & lower inertia of the needle
roller bearings help size and weight reductions in machinery.
- Though they are less wide,their load carrying capacity is high and is most suitable for applications where the
load is high & the radial space is less.
- Needle roller bearings,which are designed to withstand oscillation can operate under severe conditions &
interchange with sliding bearings.
