A bearing: (a) general rolling bearing 1 bearing rolling bearing As the rolling motion of the bearing in the bearing load and the relative motion between the parts, which includes raceway parts and with or without rolling isolation or guide. Can be used for combined load bearing radial, axial or radial and axial. 2 single row bearing single row bearing With a rolling body rolling bearing. 3 row bearings double row bearing With two rows of rolling bodies in rolling bearing. More than 4 bearing multi-row bearing With more than two columns of rolling, rolling bearing the same direction load bearing, it is best to point out the column type, number and bearing for example: "four row cylindrical roller bearing". 5 full complement bearing full complement bearing Non retainer bearing clearance, the sum of each rolling body circumference less than between the roller diameter and as small as possible, so that the bearing has good performance. 6 angular contact bearing angular contact bearing Rolling bearing nominal contact angle greater than 0 degrees and less than 90 degrees. 7 self-aligning bearing self-aligning bearing A raceway is spherical shape, can adapt to the two bearing raceway deviation angle between the axis lines and angular motion. 8 separable bearing separable bearing Rolling bearing is separable parts. 9 non separable bearing non-separable bearing In the final assembly, the bearing rings are not arbitrarily separated from rolling freely. Note: for bearing different methods of separation of components, such as two half rings (02, 01, 08) of the ball bearing not elsewhere specified abbreviated term. 10 inch bearings inch bearing When the original design dimensions and tolerances expressed in Imperial units of rolling bearings. 11 open bearing open bearing No rolling bearing dustproof cover and sealing ring. The 12 seal ring bearing sealed bearing One side or both sides are provided with rolling bearing sealing ring. 13 dust cover bearing shielded bearing One side or both sides of the bearing with dust cover. 14 closed type bearing capped bearing With one or two seal ring, bearing one or two dustproof cover and a sealing ring and a dustproof cover. 15 to lubricate the bearing prelubricated bearing Manufacturer of rolling bearings have been filled with lubricant. The 16 instrument precision bearing instrument precision bearing Instrument for roller bearing. The 17 group match bearings matched bearing With the rolling bearing a pair or group of. (two) the radial bearing 1 radial bearing radial bearing Mainly used for rolling bearings bear radial load, the contact angle of 0 ° nominal in to 45 °, basic parts of inner ring, outer ring and with or without holding the rolling body frame. 2 radial contact bearing radial contact bearing Nominal contact angle of 0 ° centripetal rolling bearing. 3 angular contact bearing angular contact radial bearing Nominal contact angle is greater than 0 ° to 45 ° centripetal rolling bearing. The 4 outer spherical bearing insert bearing A spherical and a wide inner ring with a locking element centripetal rolling bearing. Mainly for the use of a simple shell. 5 cone bearing tapered bore bearing The inner hole of the centripetal rolling bearing. The 6 flange bearing flanged bearing In a ring, the outer ring is generally conical outer ring or to the flange diameter on the centripetal rolling bearing. 7 roller (rolling bearing) track roller (rolling bearing) Thick section of the outer ring of the centripetal rolling bearing, as the wheels on the rail, such as the cam rail. 8 ring type roller (rolling bearing) yoke type track roller (rolling bearing) Roller collar with a pair of flat rolling bearing. 9 universal matching bearing universal matching bearing Choose one or more sets of the same centripetal rolling bearing when used together, can get to the first character of pairs or groups provided for installation of the. (three) the thrust bearing 1 thrust bearing thrust bearing Mainly used for rolling bearing under axial load, the nominal contact angle greater than 45 DEG to 90 basic parts, shaft ring, ring and with or without holding the rolling body frame. 2 axial contact bearing axial contact bearing Thrust bearing nominal contact angle of 90 °. 3 angular contact thrust bearings of the angular contact thrust bearing Nominal contact angle greater than 45 degrees but less than 90 ° thrust bearing. The 4 single direction thrust bearing single direction thrust bearing Only can withstand the axial load in one direction thrust bearing. Bidirectional thrust bearing 5 double-direction thrust bearing Can bear axial load in the two direction thrust bearing. 6 double row two-way thrust bearing double row double-direction thrust bearing There are two rows of rolling bodies of bi-directional thrust bearing, each column in one direction only bear axial load. 7 linear (motion) bearing linear (motion) bearing Two raceways of rolling bearings relative motion in the direction of rolling. (four) the ball bearing 1 ball bearings ball bearing Rolling body is a ball bearing. 2 radial ball bearing radial ball bearing The rolling body is a ball bearing to the heart. 3 deep groove ball bearing deep groove ball bearing Radial ball bearing continuous groove type of each ring has a cross-section about ball week three raceway. 4 filling slot ball bearing filling slot ball bearing In the groove type ball bearing each ring of a wall is filled with groove, so as to filling the ball more. The 5 locking ball bearing counterbored ball bearing An outer wall to remove all or part of the groove type ball bearing. 6 three point contact ball bearing three point comtact ball bearing Single row angular contact ball bearing when subjected to pure radial loads, each load of the ball and a channel has two points contact, but another channel
