German ORION bearings ORION models ORION prices

ORION bearings are precision mechanical components that convert sliding friction between the rotating shaft and the bearing housing into rolling friction, thereby reducing frictional losses. Rolling bearings generally consist of four parts: inner ring, outer ring, rolling elements, and cage. The inner ring fits with the shaft and rotates with it; the outer ring fits with the bearing housing to provide support; the rolling elements are evenly distributed between the inner and outer rings by means of the cage, and their shape, size, and quantity directly affect the performance and service life of the rolling bearing; the cage ensures uniform distribution of the rolling elements, guides their rotation, and provides lubrication.

ORION bearing classification

Based on the structure of rolling elements and rings, they can be classified into: deep groove ball bearings, needle roller bearings, angular contact bearings, self-aligning ball bearings, self-aligning roller bearings, thrust ball bearings, thrust self-aligning roller bearings, cylindrical roller bearings, tapered roller bearings, mounted insert ball bearings, etc. 1) Deep groove ball bearings have a simple structure and are easy to use. They are the most mass-produced and widely used type of bearing. They are mainly used to withstand radial loads, but can also withstand certain axial loads. When the radial clearance of the bearing increases, it functions like an angular contact bearing and can withstand larger axial loads. Applied in automobiles, tractors, machine tools, motors, water pumps, agricultural machinery, textile machinery, etc. 2) Needle roller bearings are equipped with thin and long rollers (roller length is 3~10 times the diameter, and the diameter is generally not greater than 5mm), resulting in a compact radial structure. When the inner diameter and load capacity are the same as other types of bearings, the outer diameter is the smallest, making them particularly suitable for support structures with limited radial installation space. Depending on the application, bearings without inner rings or needle roller and cage assemblies can be selected. In this case, the journal surface of the shaft and the housing bore surface directly serve as the inner and outer rolling surfaces of the bearing. To maintain load capacity and operating performance equivalent to bearings with rings, the hardness, machining precision, and surface quality of the shaft or housing bore raceways should be similar to those of the bearing ring raceways. This type of bearing can only withstand radial loads. Examples include universal joint shafts, hydraulic pumps, sheet rolling mills, rock drills, machine tool gearboxes, automobile and tractor transmissions, etc. 3) Angular contact bearings have high limiting speeds and can simultaneously withstand radial and axial loads, as well as pure axial loads. Their axial load capacity is determined by the contact angle and increases with the contact angle. Commonly used in oil pumps, air compressors, various transmissions, fuel injection pumps, and printing machinery. 4) Self-aligning ball bearings have two rows of steel balls, two raceways in the inner ring, and a spherical inner surface in the outer ring raceway, providing automatic self-aligning capability. They can automatically compensate for coaxiality errors caused by shaft deflection and housing deformation, making them suitable for components where strict coaxiality of the support housing bores cannot be guaranteed. This type of bearing mainly withstands radial loads and can also withstand small axial loads while under radial load. They are usually not used for pure axial loads; if subjected to pure axial load, only one row of steel balls will bear the load. Mainly used in agricultural machinery such as combine harvesters, blowers, paper machines, textile machinery, woodworking machinery, bridge crane travel wheels, and transmission shafts. 5) Self-aligning roller bearings have two rows of rollers and are mainly used to withstand radial loads, while also being able to withstand axial loads in any direction. This type of bearing has high radial load capacity and is particularly suitable for operation under heavy loads or vibration loads, but cannot withstand pure axial loads. It has good self-aligning performance and can compensate for misalignment errors. Main applications: paper machinery, reduction devices, railway vehicle axles, rolling mill gearbox housings, crushers, various industrial gearboxes, etc.

ORION bearing advantages

1) Low friction resistance, low power consumption, high mechanical efficiency, and easy starting; 2) Standardized dimensions, interchangeability, easy installation and disassembly, and convenient maintenance; 3) Compact structure, lightweight, and reduced axial dimensions; 4) High precision, high load capacity, low wear, and long service life; 5) Some bearings have automatic self-aligning capabilities; 6) Suitable for mass production, stable and reliable quality, and high production efficiency; 7) Transmission friction torque is much lower than that of hydrodynamic bearings, resulting in lower friction temperature rise and power consumption; 8) Starting friction torque is only slightly higher than running friction torque; 9) Bearing deformation is less sensitive to load changes compared to hydrodynamic bearings; 10) Only a small amount of lubricant is required for normal operation, and lubrication can be provided for extended periods during operation; 11) Axial dimensions are smaller than traditional hydrodynamic bearings; 12) Can simultaneously withstand combined radial and thrust loads; 13) Unique design achieves excellent performance over a wide load-speed range; 14) Bearing performance is relatively insensitive to fluctuations in load, speed, and operating speed.

ORION bearing selection

There are various types of rolling bearings. When selecting, consider the following factors: a. Magnitude, direction, and nature of the load. Ball bearings are suitable for light loads, while roller bearings are suitable for heavy loads and impact loads. When the rolling bearing is subjected to pure axial load, thrust bearings are generally selected; when subjected to pure radial load, deep groove ball bearings or short cylindrical roller bearings are generally selected; when subjected to pure radial load along with a small axial load, deep groove ball bearings, angular contact ball bearings, tapered roller bearings, and self-aligning ball or self-aligning roller bearings can be selected; when the axial load is large, angular contact ball bearings with larger contact angles and tapered roller bearings can be selected, or a combination of radial and thrust bearings can be used, which is particularly suitable for extremely high axial loads or special requirements for high axial rigidity. b. Permissible speed varies significantly depending on the bearing type. Generally, bearings with low friction and low heat generation are suitable for high speeds. Design should aim for the rolling bearing to operate below its limiting speed. c. Rigidity. When the bearing bears a load, elastic deformation occurs at the contact points between the bearing rings and rolling elements. The deformation is proportional to the load, and this ratio determines the bearing's rigidity. Bearing rigidity can generally be improved by preloading; additionally, considering the combination and arrangement of bearings in the support design can improve support stiffness. d. Self-aligning performance and installation errors. After the bearing is installed in its working position, manufacturing errors often cause poor installation and positioning. In such cases, excessive loads may be imposed on the bearing due to shaft deflection and thermal expansion, leading to premature failure. Self-aligning bearings can overcome defects caused by installation errors, making them suitable for such applications. e. Installation and disassembly. Tapered roller bearings, needle roller bearings, etc., belong to separable bearing types (i.e., so-called separable bearings), allowing for easy installation and disassembly.
