RNA6910 58x72x40mm Heavy Load Machined Needle Bearing Open Type For Construction Machinery Gearbox Transmission Parts
Product Overview
RNA6910 is an open double-row solid outer ring needle roller bearing without inner ring, standard dimension 58×72×40 mm. It is precisely manufactured from high-performance GCr15 bearing steel, fitted with stamped steel cage to stably retain two rows of needle rollers.Without independent inner ring, the quenched and precision-ground shaft surface acts directly as the rolling raceway, greatly saving radial installation space and allowing thicker shaft design for enhanced shaft strength. Featuring ultra-high radial load capacity and excellent structural rigidity, this open bearing supports convenient grease refilling and daily maintenance, widely adopted for heavy-duty compact transmission equipment in various industrial fields.
