NSK bearings agent: the difference between 6206 and 6306 bearing

Bearing material is correct, the quality of material is in compliance with relevant standards or design requirements, after collecting the actual background material in work, all it is hard to meet the above requirements. Caused by inadequate for cooling the bearing temperature rise should be timely check the cooling line or timely replacement cooler, FAG bearings and cooperation between shaft and bearing seat is by ISO tolerance and bearing inner hole tolerance Δ DMP and outer tolerance Δ DMP. Because of the silicon nitride high hardness, scrolling experience is creasing the convex edge smooth, until the raceway restore smooth, it will reduce the chance of local stress and spalling, significantly extend the service life of bearing. Measurement of carburized layer and multilayer metal surface strengthening layer organization such as the depth, shape and depth of corrosion pit or crack, and according to the shape of the crack and on both sides of the organizational characteristics determine the causes of cracks and properties. After machining of cleaning and pickling passivation & amp; emsp; & emsp; After machining on the surface of the stainless steel bearing usually residues at the end of the iron, steel and cooling emulsion such as dirt, can cause a blotch with stainless steel bearing surface rust, so should be skimmed oil removal, with a clean, both removed at the end of the iron steel, and has carried on the passivation. Bearing temperature is mainly by the rolling friction between the roller and the inner and outer ring raceway, the sliding friction between the roller and cage, roller end and sliding friction between the inner and outer ring guard, the quantity of heat of the friction between the roller and lubrication oil. Apart after packaging, first, to clean off rust-proof oil, cleaning of the tank by the rough washing and fine washing, and metal mesh pad on the bottom of the channel respectively, make the dirt inside the bearing is not direct contact with the cleaning trough. And provide the microhardness, friction coefficient and wear rate test: using GLC, compared with the typical bearing material, hardness is increased by two times, at least for % friction coefficient, wear rate as /. Mm, the width is two kinds of mm and mm, # mill turn ( The finished sheet frame) Quantity, between the wire to wire, bearing damage form below; Tutu figure is the group on both sides of the backing bearing inner ring damage form, on both sides of the damaged condition, the same damage location is # and # bearing inner ring in the picture. Back pack components: in order to install parts, bearing assembly suggested heated to - at the same time ℃, elevator shaft wear repair case grease or oil failure or choose wrong. For device, the rotation of the required high rotating speed and high precision of institutions, the class using level bearing, for example, the common machine tool spindle bearing, the front bearing adopts the level. Process: the lower bearing sleeve hanging out, be careful not to touch shaft neck injury, set air filter filtration precision in the item above, regular check clearing, a drain valve timing emissions at the bottom of the tank.
