Cylindrical Roller Bearing have rollers which are essentially cylindrical in shape. This provides a modified line contact with the cylindrical inner and outer ring raceways, while the rollers are guided by ground ribs on either the inner or outer ring. The cylindrical shape allows the inner ring to have axial movement relative to the outer ring (except the NH type). This is especially important when accommodating thermal expansion when both rings must be press fitted. In this series, the NJ, NF and NH types can carry light or intermittent thrust loads. The NN3000 and NN3000K series are available in high precision tolerances and are well suited for use in machine tool spindles.

Luminescence intensity in photodetectors, radiation imagers and light-emitting diodes is proportional to the thickness of the light-emitting layer. However, a thick emitting layer reduces light output because of incoherent photon scattering and attenuation. Here we present the design of double-tapered optical-fibre arrays that can drastically increase the light output of thick light-emitting layers by progressively filling more propagation modes along the fibre’s depth. To enhance the light-collection efficiency and imaging resolution, the upper taper angle of each fibre is greater than the lower angle. By filling the fibre substrate with perovskite nanocrystals from a scale of micrometres thick to centimetres thick, large-scale pixel-dense X-ray or gamma-ray detector arrays can be fabricated. We demonstrate X-ray imaging with a spatial resolution of 22 lp mm−1. Pixelated gamma-ray imaging is also demonstrated using a nanocrystal scintillator film with a thickness of 4 mm and ~10,000 pixels under focused 6-MeV irradiation. Dynamic changes in the energy spectrum (5 keV to 10 MeV) and dose rate (3.5 nGy s−1 to 96 mGy s−1) can be conveniently monitored using a hemispherical fibre array dosimeter with a field of view of 150°. This study presents a high-throughput approach for fabricating thick emitter layers that could be applied to biomolecular or mechanical force sensing, medical imaging and ion beam therapy.
