Spherical Roller Bearings refer to bearings with drum rollers assembled between an inner ring with two raceways and an outer ring with spherical raceways. Spherical Roller Bearings have a high load rating and self-aligning capability. This spherical roller bearing catalogue provides complete bearing data, including price inquiry, size selection as well as CAD drawings for free download.
Spherical Roller Bearings can take very heavy radial loads and heavy axial loads. Spherical Roller Bearings are suitable for applications at low/medium speed which involve heavy load and vibration impact.
Chrome steel is the most common material for Spherical Roller Bearings because it has characteristics of high load capacity. When there is a need for rust prevention or high temperature working environment, 440c stainless steel material is usually used.
Bore diameters of Spherical Roller Bearings range from 30mm to 1800mm and outer diameters from 52mm to 2180mm.
Open Spherical Roller Bearings are usually lubricated with oil or grease.
Sealed spherical roller bearing series are characterised by having sealing shields mounted on the external edge of both sides of the bearing. Smaller diameter sealed Spherical Roller Bearings are sometimes wider than standard bearings. Spherical Roller Bearings with seals on both sides filled with grease before leaving the factory. Basically, there exists 25 – 45% of the effective bearing space, which can protect sealed Spherical Roller Bearings against particles entering the bearings. Sealed Spherical Roller Bearings can offer many benefits for a wide range of applications. The benefits are as follows:
longer operating life in contaminated environments
lower grease consumption
environmentally friendly characteristics.
Reduced maintenance and operating costs
Reduced risk of unplanned downtime
Spherical Roller Bearings with stamped window-type steel cages, an inner ring without flanges and a floating guide ring centred on the inner ring, deliver greater fatigue strength, increased wear-resistance and tougher protection against shock and acceleration. And they are common in bearings with the suffix C,CC or ECE,CC.
Spherical Roller Bearings with machined prong-type brass cage, an inner ring with a retaining flange on both sides and a floating guide ring centred on the inner ring, feature low torque and have a high-strength. Spherical Roller Bearings of this type can be better in extreme shock and vibration. Such bearings are common in bearings with the suffix CA or ECA.
Open Spherical Roller Bearings with brass or sheet steel cage can be used at constant temperatures of 120 °C, or intermittent temperatures of up to 200°. Sealed Spherical Roller Bearings can be used at 100 °C, for short periods up to 120 °C, limited by the lubricant and seal material.
In order to ensure good lubrication, most Spherical Roller Bearings have a circumferential groove and three lubrication holes in the outer ring. The lubricant is pressed into the bearings via the groove and holes. Due to the direct and symmetrical feed system, a uniform supply of lubricant to the rows of rollers is achieved. The amount of grease filling can refer to two general situations.
1) The horizontal installed Spherical Roller Bearings fill 2/3-3/4 of the cavity space;
2) The vertically installed Spherical Roller Bearings fill 1/2 (upper side) and 3/4 (lower side) of the cavity space;
The internal clearance of Spherical Roller Bearings is divided into original clearance, installation clearance and working clearance. Usually, the original radial clearance of Spherical Roller Bearings is larger than the working clearance. Bearing internal Clearance is an important technical parameter of the Spherical Roller Bearings. It directly affects the technical performance of the bearings. If the working clearance of bearings is too small, the friction torque of the bearings will be increased, which will easily lead to heat damage to the bearings. On the contrary, If the working clearance of bearings is too large, which will reduce the motion accuracy of the bearings, increase the vibration and noise, and reduce the service life of the bearings. Therefore, it is important to select different levels of bearing clearance according to operating conditions.
Spherical Roller Bearings, as a standard, have radial internal clearance CN (normal). Some bearings are also available by agreement with the smaller internal clearance C2 and with the larger internal clearance C3 and C4,C5.
Spherical Roller Bearings are widely used in different kinds of fields. Some typical applications are as follows:
Power Plant Maintenance Vibrating Screen
Printing Machine Crusher
Various Industrial Reducers Mechanical Fans and Blowers
Continuous Casting Machines Pumps
Mining and Construction Equipment Gearboxes
Wind Turbines Railway Vehicle Axles
Mill Rolls Off-road Vehicles
Woodworking Machinery Material Handling
Pulp and Paper Processing Equipment Cement Mixer
Marine Propulsion and Offshore Drilling
