[Music] 0:05 this 0:06 skf training film is about deep groove 0:09 ball bearings 0:10 the deep groove ball bearing is the most 0:12 commonly used bearing in industry 0:15 being ideal for light loads and high 0:17 speeds 0:18 it consists of an inner and outer ring 0:20 and a set of balls 0:21 separated by a cage this bearing can 0:24 accommodate 0:25 radial and a combination of light radial 0:27 and axial loads 0:29 the bearing can be supplied in open 0:31 condition or with one or two seals or 0:34 metal shields 0:35 completely sealed or shielded bearings 0:38 are pre-greased during the manufacturing 0:40 process 0:41 and cannot be re-lubricated 0:44 they are commonly used in small electric 0:46 motors gearboxes 0:48 conveyor support rollers and similar 0:50 equipment 0:52 [Music] 0:56 the most common way of mounting small 0:58 deep groove ball bearings is in a cold 1:01 condition 1:02 using the skf fitting tool the required 1:05 items are shown in the instructions for 1:08 [Music] 1:10 use 1:12 do not remove the bearing from its box 1:14 until everything is ready 1:16 before mounting deep groove ball 1:18 bearings care must be taken to ensure 1:20 that the shaft and housing are not 1:22 damaged or worn 1:24 the use of some light oil on the shaft 1:26 will assist the fitting 1:28 [Music] 1:31 for medium to large size deep groove 1:33 ball bearings 1:34 heat is often used to expand the bearing 1:36 inner ring 1:38 skf provides a wide range of bearing 1:40 induction heaters 1:41 for this purpose in this instance a 1:44 portable induction heater is used 1:48 do not heat the bearing above 110 1:50 degrees centigrade 1:51 and always use protective gloves 1:53 [Music] 2:00 the bearing should be held against the 2:02 shaft shoulder until it cooled 2:03 sufficiently to grip the shaft 2:08 from the dismounting of deep groove ball 2:10 bearings a number of methods are 2:12 available 2:13 depending on the setup of the bearing 2:16 the most frequently used method is for 2:18 bearings with an interference fit on the 2:20 shaft 2:21 for this application a jaw type puller 2:24 can be used 2:24 [Music] 2:31 the bearing can be easily dismounted 2:33 from the shaft with minimum damage to 2:35 the raceways 2:40 in applications where it is not possible 2:42 to get behind the bearing 2:44 skf provides a blind puller kit 2:47 select the parts according to the 2:48 instructions for use 2:50 [Music] 2:56 the puller is assembled by placing the 2:57 specially designed tips between the 2:59 inner 3:00 and outer raceways ensuring pulling 3:02 forces are on the outer bearing track 3:06 with this method the bearing should 3:08 never be reused 3:16 in applications where the only access is 3:18 through the bore of the bearing 3:20 skf provides a split collet impact 3:23 puller 3:24 the correct collet size is shown in the 3:26 instructions for use 3:32 [Music] 3:56 when mechanically mounting deep groove 3:58 ball bearings damage 4:00 to the bearing can occur if the mounting 4:02 force is applied to the non-locating 4:04 bearing ring 4:05 as this would allow the shock load to be 4:07 transmitted through the rolling elements 4:10 the force must always be applied to the 4:12 ring with the interference fit 4:14 deep groove ball bearings are supplied 4:16 with a range of predefined radial 4:18 internal clearances normal clearance is 4:21 not marked 4:23 bearings with a greater than normal 4:24 clearance are marked with the c3 mark 4:28 always make sure the replacement bearing 4:29 is identical and has the same 4:31 internal clearance as the original 4:46 [Music] 4:50 you
