Whether buyers or sellers are concerned, the length of the bearing life. Such as: flanged bearing mainly take radial load, but also to support radial and axial load. But for the life of the Flange Slewing Bearing are not very understanding, the following three steps teach you extend bearing life:(1) In order to make a gap in the radial direction between the bearing retainer and the bearing ring is set larger than the eccentric amount of the internal structure has been improved;(2) the use of FEM analysis, by the shape and thickness were optimized to improve the strength of the holder;(3) In order to prevent reduce surface damage caused by lubricating oil in the bearing ring in the design of the guide groove.

Roller bearings and roller ball bearings of the same points that they are high-vice campaign; all rolling bearings, has the characteristics of the performance of rolling bearings. The difference is that roller bearings deputy campaign and roller bearings are point contact and line contact. The use of roller bearings, printer manufacturers are still making trouble in the need for processing high precision coat, and need an experienced installer to find the right needle group. To solve this problem, manufacturers developed a bearing outer ring flanged ball bearing. Roller bearings can achieve good precision and rigidity through preloaded. And you can also use the inner tapered to arbitrarily adjust the bearing clearance. Such solutions can achieve zero printer roller bearing clearance requirements. View Details

Slewing ring turntable bearings, also known, is a comprehensive large bearings to withstand load, can withstand large axial, radial load and overturning moment. Wheel bearings in general with mounting holes, internal gears or external gears, lubricants holes and sealing devices, which enable the host compact design, the guide is simple, easy to maintain. Have toothed wheel bearing, external tooth and internal tooth four-point contact ball bearings, double row angular contact ball bearings Crossed cylindrical roller bearings, tapered roller bearings and cross three-row cylindrical roller bearings four series compound , the wheel bearings large rotary devices are widely used in lifting machinery, mining machinery, construction machinery, port machinery, ship equipment and high-precision radar and missile launchers and other mechanical equipment. But also according to the user's specific requirements and design, development and production of special structures wheel bearings. View Details

Reason 1: excessive lubricant, countermeasures: reducing lubricant grease, proper use, select the hard.2 reasons: lack of lubricant or not suitable, countermeasures: thin section angular contact bearings add lubricant, select the appropriate lubricant.Reason 3: abnormal load, countermeasures: modify the coordination, clearance of bearing pre load, ... Reason 1: excessive lubricant, countermeasures: reducing lubricant grease, proper use, select the hard.2 reasons: lack of lubricant or not suitable, countermeasures: thin section angular contact bearings add lubricant, select the appropriate lubricant.Reason 3: abnormal load, countermeasures: modify the coordination, clearance of bearing pre load, adjust, modify the shoulder position of the shell.Reason 4: poor installation, countermeasures: improve machining precision, and shell axis installation accuracy, installation method.Reason 5: surface creep, seal friction is too large, countermeasures: replacement of bearings, study, modify the shaft and housing, changes the sealing form.Vibration (axial runout)Reasons: (1 Steel Carburized) surface deformation, Full complement cylindrical roller bearing countermeasures: Note bearing replacement operation.Reason 2: peel, countermeasures: replacement of dental bearings.Reason 3: poor installation, countermeasures: axis, shell shoulder pad angle, side angle.Reason 4: foreign intrusion, countermeasures: replacement of bearings, cleaning parts, improved sealing device.Lubricant leakage is overmuch, discolorationCause: excessive lubricant, foreign intrusion, wear powder foreign body, countermeasures: proper use of lubricant, change the selection of lubricant, the replacement of bearings, cleaning shell.

Heat treatment equipment bearing bearing directly affect the quality of heat treatment, as well as energy consumption and pollution. In recent years, with the advancement of technology, the development trend of heat treatment technology is mainly reflected in the following aspects:     (1) Clean the heat production and heat treatment of wastewater, waste gas, waste salt, oil and electromagnetic radiation on the environment etc forming pollution. Solve the heat problem of environmental pollution, the implementation of clean heat (or green heat) is one of the direction of the heat treatment technology. This atmosphere heat treatment, quenching oil, and cleaning equipment are high demands.     (2) Precision Precision heat is sufficient to ensure the optimization of the heat treatment process stability, and product quality the dispersion of small (or zero), heat distortion is zero, reducing the grinding allowance increase productivity, save material. Precision heat treatment must have good temperature uniformity, temperature control accuracy, as well as hardening agents good cooling and stability. Achieve high precision ball bearings heat can go the whole way hardening and induction hardening two. View Details
