The slewing bearing usually consists 4 parts: inner ring, outer ring, rolling element & toroid.
Thin-section bearings sometimes also were called slewing bearing, they were designed to save space, lower the overall weight of your designs, dramatically reduce friction, and provide excellent running accuracy.
Our OEM slewing bearing was successfully used on the reducer.

We know that the thermal power industry are generally more harsh environments , such as mill equipment must be dust pollution, high speed operating environment , in order to avoid issues such as maintenance and downtime , so its relevant components of the device is quite high technical requirements especially bearings and other components required quality and performance is outstanding , Timken Company, as many years of thermal power industry suppliers , and how to meet the requirements of the thermal power industry customers do ? Timken bearings distributor in China will take you to see this TIMKEN thin bearings thermal power industry applications. Thermal power industry an important machine mill , and mill roller ball bearing screwon the working environment is dust, high temperature low and insufficient lubrication of the environment, this has led to coal grinding equipment gearbox mounting or improper lubrication and reduce efficiency , Timken bearing thermal power industry in order to help solve these problems , the accumulation of years of experience under TIMKEN bearing technology has developed a lot in this regard Timken bearing products such as Abrasive bearings , DuraSpexx power density range of bearings and solid lubricated bearings. This column bearings can be used in harsh operating under production conditions , and the ability to extend the equipment uptime , which help customers improve the mill , gear boxes, and air preheater , conveyors and other equipment performance.

SKF distributor in China from the Swedish SKF Group has learned that in order to maintain optimal thermal power plant safety, reliability and availability, SKF thermal power plants tailored specifically for proactive maintenance plan integrated equipment reliability program solutions.Even for experienced plant manager, the construction of new power plants or existing plant operators are likely to be a big challenge. Must achieve and maintain optimal security, reliability and availability. To achieve these goals, we must develop a reliable and cost-effective maintenance plan, usually need to limit the number of personnel and expenditures. This requires an organized, dedicated integrated equipment reliability (IER) program, which the plant's CMMS or EAM system seamlessly to the existing number of personnel and technology will be able to manage.SKF Bearing Company of the slewing high speed bearingsof integrated equipment reliability programTo bring best practices knowledge Experiences using other plants Development of cost-effective PdM activities Integrated hardware, software and data configuration Small impact on staff Rapid results Use of existing tools and techniquesSweden SKF Bearing Applications integrated device reliability program case: In the 15 plants have 27 coal and gas supply companies operating unit is facing reliability and performance issues. The goal is to reduce equipment failure, appropriate centralized maintenance resources. SKF has developed a proactive maintenance program, focusing on critical equipment planned maintenance and major failure mechanism. As more attention to the task of those states to monitor and eliminate unnecessary tasks, the plant reduced maintenance costs, SKF Bearing solutions and improve the availability and reliability.
Cylindrical roller bearings |

Roller ball bearing is cylindrical, conical or drum-shaped roller for rolling element bearing. Roller bearings are mainly radial cylindrical roller, double row spherical roller, tapered roller and thrust roller and structure type.Edit this paragraphRoller BearingsSuch roller is mainly used for cylindrical roller bearings, roller assemblies can also be used directly for machinery. This class roller has been standardized in size, can be used as commodities roller for design and user choice. Long cylindrical roller bearingsThis class roller shaft divided in two with and without shaft, mainly for long cylindrical roller bearings, roller assemblies can also be used directly for machinery.Needle roller bearingsSuch is mainly used for needle roller bearings, needle roll bearings universal joints and thrust needle roller bearings, needle roller assembly can also be used directly for machinery. This class roller has been serialized in size for the design choices. Bearing structure according to the needs of both ends of the needle shape of cone-shaped head, flat head shape, round shape.Tapered Roller BearingsA circular truncated cone, the cone angle is typically 1 ° ~ 4 ° 20 ', is also less than 1 ° or greater than 4 ° 20', mostly 2 °. Roller length is generally not more than twice the diameter of the large end rollers. Such rollers are used for tapered roller bearings, roller large cone angle is basically used for thrust tapered roller bearings.Spherical roller bearingsRoller raceway spherical shape. With this roller bearings with self-aligning properties, can withstand large loads. Spherical roller of asymmetric and symmetric shape, generally large end asymmetrical spherical, symmetrical both end faces of the flat face. Symmetrical spherical roller better performance, rather than the symmetrical form for elimination. Such roller for spherical roller bearings and spherical roller thrust bearings.Spiral roller bearingsIt is a special section of the hollow roll made steel rollers, two kinds of left and right hand. The roller application is not very extensive, mainly used by the impact load spiral roller bearings.Pillar hole roller bearingsRoller central pillar holes band-pass hole that used to hold pillar to pillar cage fixed to the sheet. This class roller shape cylindrical, conical, spherical shape, mainly for large bearings.

Slewing bearing generally known as the machine connection parts for machinery is a must drive links, called slewing bearing macro-speaking parts, often as a supporting member before the base component of CNC machine tools, including uprights, rocker, knife and bed, as well as beams and lifts and other components. Where there is a known bearing supporting the auxiliary support, auxiliary support improves the rigidity of the workpiece, of course, plays a role in limiting freedom. In fact, two meanings play a role is the same: that he and processing, in order to achieve and improve the precision and efficiency, corresponding slewing different installation methods, impose constraints when applied to the surface can be fully constrained inner circle, can also be applied to the surface of foreign outsiders fully constrained. Different shape of the slewing ring raceway carrying capacity greater impact, oval raceway Mises stress than the circular raceway Mises stress should be small, ie oval raceway slewing ring bearing capacity than round slewing ring raceway higher carrying capacity. The level of increase of about 28% or so, slewing ring during use, generally axial force, radial force and overturning moment together, for different applications, as the host of the working methods and structures in different forms, the The role of three kinds of load combinations will change, as it involves a large bearings, manufacture and installation of a variety of factors will have a process failure, these failures are usually manifested through vibration.
