Founded in 2014, Luoyang Ona Bearing Co., Ltd. is located at No.76 Airport Road, Luoyang Airport Industrial Cluster Area. It is an enterprise specializing in R & D, design, manufacture and sale of high-precision bearing products. The main products are: thin-walled cross roller bearings, high-precision ORT series turntable bearings, precision four-point turntable bearings, cross tapered roller bearings, precision ring guide rail series and hydrostatic turntable series, with accuracy grades of P5, P4 and P2, and sizes ranging from φ20mm to φ2500mm. It is widely used in various fields such as humanoid robot, high-precision CNC four-axis five-axis turntable, CNC vertical bed, dividing head, direct-drive motor, DD motor, high-end CNC grinder, industrial robot, five-axis machining center, automation equipment, carving machine, laser cutting machine, intelligent workshop, medical equipment, new energy field, precision measuring instrument, etc.

In the cross cylindrical roller bearing, since the cylindrical rollers are arranged perpendicularly to each other on a V-groove rolling surface of 90 deg by a spacer or a spacer block, a single bearing can bear loads in all directions such as radial load, axial load and overturning moment. The size of the inner and outer rings is minimized, and particularly the extremely thin type is a compact size close to the limit, and has high rigidity and high rotational accuracy and composite load capacity.

YRT rotary table bearing is included by a thrust race/radial race, a thrust gasket, two needle rollers with cage assembly and a set of centripetal roller. There is the screw holes which is used for installed on the race and circle. YRT bearings has the high axial rigidity, high radial loading capacity, high stiffness and high accuracy.
The main products are: thin-walled cross roller bearings, high-precision YRT series turntable bearings, precision four-ball bearings, special bearings for humanoid robots, special bearings for harmonic reducers, annular guide rails, non-standard customized bearing series, with precision grades of P5, P4 and P2, and sizes ranging from φ20mm to φ2500mm. Cross cylindrical roller bearings are ORAU, ORA, ORB, ORE, ORU series, ORB, ORBC, ORBF, ORBH, ORBS, ORBT series, OSX, OXU, OXSU, OXSA, OXSI series; cross tapered roller bearings are JXR, XR series.
