Bearing testing methods and strategies
Bearing testing methods and strategies
The main reasons for bearing testing are:•Technical validation / supplier approval•Comparative assessment (applies to different suppliers or to different production methods•Continuous quality control for incoming or outgoing inspectionsWe use an overview of different testing methods, the required equipment and testing strategies. The main testing methods are for frictional torque or temperature and for endurance. Both have their justification depending on what is most critical in the associated application. Testing methods:Among testing methods, one firstly has to distinguish between testing for frictional torque or temperature and testing for endurance. Friction and temperature testing can help understand the effect of various operating conditions on the frictional torque and the equilibrium temperature. Such tests can help to evaluate power losses due to friction which contribute to the overall system efficiency. As an example, the losses in individual bearing elements in the drivetrain of an automobile and hence the total efficiency of the drivetrain can be evaluated. This testing method can also be used to provide a quick evaluation of the quality standards of regular deliveries (incoming inspections) and to identify performance limits. Finally, steady state temperature can be a performance limiting criterion for grease lubricated bearings.Endurance testing is used in order to evaluate the bearing lifetime under sustained use. Testing can be used to validate if the performance of the bearing and the lubricant comply with the technical specifications or expectations. When switching to or acquiring a new supplier one typically needs to ensure that the performance of the new product is better – or at the least not worse – than the current supplier. An accelerated endurance test can provide a quick comparative assessment of different suppliers and help one to make an informed decision. An endurance test which extends beyond theoretical life rating can also provide a quick test for incoming inspection.
Stainless steel bearings
Stainless steel bearings
Specs•AISI 304 stainless steel ball bearings have much greater corrosion resistance than those made of SAE 52100 bearing steel or AISI 440C stainless steel•Heat resistant grease is used in AISI 304 and AISI 440C stainless steel ball bearings•AISI 440C stainless steel bearings have a high resistance to corrosion and chemicals, plus high stability in high temperaturesApplications:•Agricultural•Food Processing•Gearbox & Industrial Clutch•Health care•Material Handling•Packaging Machinery•Pump & Compressor•RoboticsStainless steel bearings provide a several notable benefits when other materials pose problems. Notably, stainless steel offers greater chemical and corrosion resistance, along with better stability in high temperature environments. These benefits make stainless steel bearings a great fit for applications in demanding environments or specialty circumstances.Stainless steel deep groove ball bearings are corrosion resistant when exposed to moisture and several other media. They are available capped (with seals or shields) or open. Open bearings that are also available capped may have recesses in the ring side faces.These bearings have a lower load carrying capacity than same-sized bearings made of high chromium steel.Stainless Steel Pillow Block Bearings not only have the characteristics of the ordinary bearings: Low vibration, low noise, high precision rotating, lower friction torque and high speed running but also have its special usage function.The range of application is wide: It is an acid-proof and alkali-proofIt can work in corrosion medium such as sea water, river aqua, distilled water, sparse nitric acid, maritime climate, steam and so onIt can work in the high or low temperature environmentCommon usage for Stainless Steel Pillow Block include: Agriculture, Automotive, Pump, Sporting and Consumer Goods, Construction, Manufacturing Equipment, Conveyor and Fan Assemblies,Farm Machinery, HVAC, Feed Mill, Economical housed bearing solution and many other Industrial Equipment.Main model: UCP , UCFL , UCF , UC

Customized thrust ball bearing manufacturers FromChina
Thrust ball bearings are separable bearings. Thrust ball bearings, composed of bearing balls supported in a ring, can be used in low thrust applications where there is little axial load.The thrust ball bearings are classified into two kinds: unidirectional thrust bearing and bidirectional thrust bearing. The former can bear the axial force in one direction and the latter can bear he axial forces in two directions. Both unidirectional and bidirectional thrust ball bearings cannot bear any radial force. Thrust ball bearing can limit axial displacement of shafts or housings in one or two direction, but not radial displacement. Therefore, the bearings are usally used with deep groove ball bearings.Features1.Available in two designs: single direction and double direction.2.To accommodate initial misalignments in an assembly both designs are available with spherical aligning seats or aligning seat washers.3.High quality steel-ultra clean steel to extend bearing life by up to 80%.4.Advanced Grease Technology — lubricants that can extend grease life and performance.5.High Grade Balls — Quiet and smooth operation even at high speed.6.Optional seating rings take initial misalignment.Wuxi LOTTON Bearing Manufacturing Co., Ltd.
