Cylindrical roller bearing cylindrical roller and track are line touch; radial load can be large; that is suitable for receiving heavy load and impact load; also suitable for high-speed rotation N-type and NU-type can be moved axially; can be used to thermal expansion or The change of the relative orientation of the shaft and the casing caused by the equipment error; the most suitable for the free end bearing NJ type and NF type can accept a certain degree of unidirectional axial load; NH type and NUP type can accept a certain degree of bidirectional axial load The ring or outer ring can be separated; it is easy to assemble and disassemble NNU type and NN type with strong rigidity against radial load; mostly used for machine tool spindle. /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
The first applicable adherence frame: steel plate stamping frame (Z-shaped), copper alloy cutting frame, pin-type frame, synthetic resin forming frame.
Primary use: medium and large motors, generators, internal combustion engines, gas turbines, machine tool spindles, gear reduction equipment, loading and unloading transfer machinery, various industrial machinery.
The basic layout of the solid needle bearing has the same inner ring bearing as the NU type cylindrical roller bearing; but because of the selection of the needle roller; the volume can be reduced. 15. The sand 惺艽缶 惺艽缶 蚋 晌 晌 晌 谌χ岢 谌χ岢 鲜 鲜The group of tortoises smashed the hustle and bustle.
The first applicable adherence frame: steel plate stamping adheres to the frame.
Primary use: automotive engines, transmissions, pumps, excavator track wheels, hoists, bridge cranes, compressors.
Tapered Roller Bearings This type of bearing is equipped with a truncated roller; the roller is guided by the large rib of the inner ring. The poles of the conical surfaces of the inner ring raceway surface, the outer ring raceway surface and the roller tumbling plane are depicted. A point on the middle of the bearing.
Single row bearings can accept radial loads and one-way axial loads; double row bearings can accept radial loads and bidirectional axial loads.
Applicable to accept heavy load and impact load; according to the touch chest (α) is different; divided into small cone angle, middle cone angle and large cone angle three types; the larger the touch angle, the greater the axial load can be. It can be separated from the inner components (inner ring and roller and the bracket assembly); it is easy to assemble and disassemble; the bearing with the rear code "J" or "JR" has world interchangeability. This type of bearing also uses the British series.
The first applicable adherence frame: steel plate stamping frame, synthetic resin forming frame, pin-type frame.
Primary use: Automobile: front wheel, rear wheel, transmission, differential pinion shaft. Machine tool spindle, construction machinery, large agricultural machinery, railway vehicle gear reduction equipment, rolling mill roll neck and deceleration equipment.
Spherical Roller Bearings This type of bearing is equipped with a spherical roller between the outer race of the spherical raceway and the inner race of the double raceway; it is different according to the internal layout; it is divided into four types: R, RH, RHA and SR; The middle of the arc of the track is common with the middle of the bearing; it has a self-aligning function; thus it can actively adjust the axial misalignment caused by the deflection of the shaft or the casing or the different core. Acceptable radial load and bidirectional axial load. Especially the diameter The load can be large; it is suitable for accepting heavy load and impact load. The tapered hole bearing can be assembled and disassembled on the shaft through the use of fasteners or withdrawal sleeves.
There are two types of tapered holes (taper):
1:30 (auxiliary code: K30) ... applies to the 240, 241 series.
1:12 (auxiliary code: K).........Applicable to other series.
Oil holes, oil grooves and positioning pin holes (one) can be set on the outer ring. Oil holes and oil grooves can also be opened on the inner ring.
The first applicable adherence frame: copper alloy cutting frame, steel plate stamping frame, pin-type frame, synthetic resin forming frame.
Primary use: paper machine, deceleration equipment, railway vehicle axle, rolling mill gear box seat, rolling mill roller table, crusher, vibrating screen, printing machinery, woodworking machinery, various industrial speed reducers, vertical belt seated self-aligning bearings .
The thrust ball bearing consists of a washer-shaped raceway with a raceway and a ball and a bracket assembly. The raceway ring that cooperates with the shaft is called a shaft ring; the raceway ring that cooperates with the outer casing is called a raceway. The two-way bearing is in the middle. Coupling shaft cooperation; one-way bearing can accept one-way axial load; two-way bearing can accept two-way axial load (both can not accept radial load).
The first applicable adherence frame: steel plate stamping frame, copper alloy or phenolic resin cutting frame, synthetic resin forming frame.
Primary use: car steering pin, machine tool spindle.
The thrust cylindrical roller bearing is composed of a washer-shaped raceway ring (shaft ring, race) and a cylindrical roller and a bracket assembly. The cylindrical roller is processed by convex surface; thus the pressure between the roller and the raceway surface is evenly distributed; Accepts one-way axial load; axial load can be large; axial rigidity is also strong.
The first applicable adherence frame: copper alloy cutting and sticking frame primary use: oil drilling rig, steel making steel mechanical thrust needle roller bearing separate bearing consists of raceway ring and needle roller and holding frame assembly; thin rolling with stamping processing The raceway (W) or the cut thickened raceway ring (WS) is a comfortable combination; the non-detachable bearing is a single-piece bearing consisting of a finely stamped raceway ring and a needle roller and a holder assembly. To the axial load. This type of bearing occupies space. Xin 诨 舸 舸 舸 舸 æ“ æ“ æ“ è – è – è – è – è – è – è – è – è – è – è – è – è – ç‰’æ… ç‰’æ… ç‰’æ… ç‰’æ… ç‰’æ… ç‰’æ… ç‰’æ… ç‰’æ…
The first applicable adherence frame: steel plate stamping, synthetic resin forming and holding frame.
Primary use: variable speed equipment for automobiles, cultivators, machine tools, etc.
Thrust tapered roller bearing This type of bearing is equipped with a truncated cone roller (the large end is a spherical surface); the roller is precisely guided by the raceway ring (shaft ring, race) rib; the bearing is made to make the shaft ring and raceway raceway surface And the poles of the conical surfaces of the roller rolling surface intersect at a point on the middle line of the bearing. The one-way bearing can accept the one-way axial load; the two-way bearing can accept the two-way axial load. The two-way bearing cooperates with the shaft in the middle ring; Because the use of voids cooperation; therefore, the axial alignment of the middle ring must be used with the bushings, etc. The first applicable support frame: copper alloy cutting support frame.
Primary use: one-way: crane hook, oil rig swivel,
Two-way: rolling mill roll neck.
Thrust spherical roller bearing The spherical roller in this type of bearing is placed obliquely; because the raceway surface of the raceway is spherical; it has a self-aligning function; therefore, it can be allowed to have a number of skews; the axial load can be very large; The load together can also accept a number of radial loads; the oil is usually selected for smooth application.
The first applicable shelf: copper alloy cutting frame.
Primary use: hydroelectric generators, vertical motors, propeller shafts for ships, reducers for rolling mill rolling screws, tower cranes, coal mills, extruders, forming machines.
