Jiaxing bearing general agent for you to share the installation of precision bearing

There is rotational, have HRB bearing ( ) Jiaxing bearing general agent for you to share the installation of precision bearing. Jiaxing bearing group sales co. , LTD. ( The company) Is bearing group co. , LTD. Established in jiaxing spot sales window, specializing in HRB brand bearings, existing stocks of 50 million yuan, covers the whole bearing, have very strong cash supply ability. Precision bearing installation and installation tool spindle, screw with precision bearing as the basis of machine tool accessories, its performance directly affects the speed of the machine tool, rotary accuracy, rigidity, chatter vibration cutting resistance, noise, temperature rise and thermal deformation, etc. , which affect the precision and surface quality of machining parts, etc. 1. Precision bearing installation considerations for precision bearing assembly site should be kept clean; Avoid precision bearing pollution or the entry of foreign body, pollutants on the running and service life of bearing has great impact; Check the bearing hole and shaft with the geometric accuracy, dimensional accuracy, and cleanliness; When installation in ring mating surface coated with a little oil, or a little fat, precision bearings are easier to install to design parts; Design of bearing hole and shaft should be a 100 ~ 150 installation guide chamfer; Don't be cooling the bearing, because with condensation can lead to bearing and the bearing surface rust; Bearing inner ring and shaft assembly with the directional assembly method or Angle matching method, which is artificially control the direction of the radial runout of assembly errors, reduce the error offset each other instead of accumulation; After bearing pressure into the bearing should be flexible rotation without block feeling; After the installation is complete, check whether the precision bearing system is working properly. 2. The rational use of installation tools ( 1) When large amounts of interference, can use heating box, oil bath heating or heating bearings to install the sensor, the heating temperature range of 80 ℃ ~ 100 ℃, the highest must not exceed 120 ℃. At the same time, nut or other appropriate method is applied to tighten the bearing, in order to prevent the bearing width after cooling contraction and make the clearance between the ring and the shaft shoulder. ( 2) Bearing installation, it must be in the ring width on the circumference of a circle of equal pressure, to press the ring into, can not use ð ¨ +  top tools directly on bearing face, in order to avoid In the case of a small amount of interference, but at room temperature with the sleeve pin bearing ring end face, with a ð ¨ +  head tap the center of the sleeve assembly, through the sleeve ring is balanced Assembly force can't pass through rolling body, avoid direct hammer bearing ring. Fashionable, should guarantee the outer end face and the shell shoulder end face, inner ring end face and the shaft shoulder end face pressure, there is no gap. ( 3) Adopt mechanical press or hydraulic press must use assembly sleeve being connected, and guarantee in the level state, such as with sloping channel by mechanical damage can lead to bearing, and make the bearing produces sound. Assembly sleeve to fully contact bearing inner ring or outer ring width of the entire circumference. 。 24-hour customer service hotline: if you are interested in the above the bearing the general introduction of jiaxing industry information or have any questions, please click on contact us page on the right side of the online customer service, or call:, you close the way of jiaxing bearing purchasing advisors. - - - - - - Editor: jiaxing bearing general agent HRB bearing sourcing consultant LTD.
