Tapered roller bearings are separated bearings, and the inner and outer rings of the bearings are equipped with tapered raceways. This kind of bearing is divided into single row, double row and four row tapered roller bearings and other different structural types according to the number of rows of rollers installed, and is widely used in automobile, rolling mill, mining, metallurgy, plastic machinery and other industries. Product name Professional Manufacturer Supply KOYO 32208JR Tapered Roller Bearing Bearings Feature 1 Long life span 2 low rotation&impact resistance&vibration resistance Material Chrome Steel Bearing Package Pallet,wooden case,commercial packaging or as customers' requirement. Service OEM service provided Delivery time 3-15 days depends on quantity needed Structure: This type of bearing is equipped with a round platform roller, the roller by the inner ring of the large rim. Single row bearings can bear radial load and unidirectional axial load, and double row bearings can bear radial load and bidirectional axial load.Suitable for bearing heavy load and shock load. According to the different contact Angle (α), it can be divided into three types: small cone Angle, middle cone Angle and large cone Angle. The larger the contact Angle is, the greater the axial load capacity is. Outer ring and inner assembly (inner ring and roller and cage assembly) can be separated for easy assembly and disassembly. Bearings with rear auxiliary code "J" or "JR" have international interchangeability. Common uses of tapered roller bearings A tapered roller bearing is appropriate wherever a bearing must handle combination loads. One of the most common uses is maintaining axial balance, achieved with multiple tapered roller bearings along an axle or shaft. The tapered bearings will evenly distribute loads when adequately aligned, minimizing wear and tear on the components. With higher surface area, tapered roller bearings can distribute friction and heat from combination loads more efficiently than non-tapered rollers (which are more efficient than tapered bearings only with the most straightforward non-combination forces). This reduced friction increases the rotational speed of interfacing parts and makes tapered roller bearings ideal for use in: Engines Motors Gearboxes (especially those with helical gears) Wheels & axles Turbines & propellers This equipment must combine many different angles and utilize them to drive motors, driveshafts, and other rotational components.
Tapered roller bearings are separated bearings, and the inner and outer rings of the bearings have tapered raceways. This kind of bearing is divided into single row, double row and four row tapered roller bearings and other different structural types according to the number of rows of rollers installed. Single row tapered roller bearings can bear radial loads and single direction axial loads. When the bearing bears radial load, an axial component will be generated, so it needs another bearing that can bear the axial force in the opposite direction to balance it.

A single-row tapered bearing is usually adequate for the most straightforward applications (e.g., angular forces on a fixed point and with only mild fluctuation). To find the right one, you'll need to determine whether the end-use of the tapered bearing will have more radial or axial loads. There are axial-only tapered roller bearings called thrust tapered bearings that resemble flat rings or disks where the rollers are perpendicular to the bearing bore axis. When multiple bearings are required, it could be advantageous to use two- or more single-row tapered bearings rather than multi-row bearings within a single housing. One such example is if one bearing will need to be maintained, adjusted, or replaced separately from the other. Another is when there is a need to allow for flexibility in design and add or subtract individual single-row tapered bearings, which is impossible with a multi-row tapered bearing.

It consists of an outer ring, an inner ring, a set of steel balls and a set of cages. It mainly bears pure radial loads, but also can bear joint loads. We have three seal types：ZZ type、2RS type、Open type.
Needle Roller Bearings (needle bearing) is a cylindrical roller with roller bearings, relative to its diameter, roller both thin and long. This is called needle roller. Despite having a smaller cross-section,has a higher load bearing capacity, equipped with a thin and long needle bearing roller (roller diameter D≤5mm,L / D≥2.5, L is the length of the roller), so radial structure is compact, its diameter size and load capacity and other types of bearings, minimum diameter, especially for radial dimensions limited support structure.
Single row cylindrical roller bearing is usually only subject to radial force, compared with the ball bearing of the same size, the radial bearing capacity is increased by 1.5-3 times, good rigidity, impact resistance, it is especially suitable for rigid support, and support the short shaft, heat elongation caused by axial displacement of the shaft and the installation and disassembly of the machine accessories need separation type bearing.
Spherical Roller Bearing: The outer ring is a sphere with the center point of the bearing as the ball center, with automatic aligning, linear contact between the rolling body and the inner and outer ring raceway and can withstand large radial load. Suitable for mining, metallurgy, paper making, construction and other large machinery and equipment.
Oil seals – often called grease, fluid or dirt seals – close spaces between stationary and moving components in mechanical equipment, helping prevent lubricant escape. 10*32*7 10*32*10 12*32*5 12*32*7 12*32*10 13*32*7 14*32*7 14*32*8 14*32*10 15*32*7 15*32*9 15*32*10 16*32*7 16*32*8 16*32*10 17*32*5 17*32*6 17*32*7 17*32*8 17*32*9 17*32*10 18*32*6 18*32*7 18*32*8 18*32*10 19*32*4 19*32*5 19*32*6 19*32*7 19*32*8 19*32*9 19*32*10 20*32*5 20*32*6 20*32*7 20*32*8 20*32*10 21*32*5 21*32*7 22*32*5 22*32*5.5 22*32*6 22*32*7 23*32*5 23*32*7 24*32*4 24*32*7 25*32*4 25*32*5 25*32*7 14*33*6 15*33*7 15*33*9 16*33*4 16*33*7 17*33*7 19*33*7 19*33*8 20*33*7 20*33*10 20*33*12 21*33*7 22*33*7 22*33*10 24*33*7 25*33*6 25*33*7 25*33*10 6*34*7 8*34*8 12*34*7 14*34*7 15*34*7 16*34*7 17*34*4 17*34*6 17*34*7 17*34*8 18*34*7 18*34*8 19*34*7 19*34*8 20*34*7 22*34*5 22*34*6 22*34*7 22*34*8 23*34*8 24*34*5 24*34*5.5 24*34*6 24*34*7 24*34*8 25*34*5 25*34*5.5 25*34*6 25*34*7 25*34*8 26*34*7 6*35*7 10*35*4 10*35*8 12*35*6 12*35*7 12*35*10 13*35*7 14*35*7 14*35*8 14*35*10 15*35*5 15*35*6 15*35*7 15*35*8 15*35*10 16*35*6 16*35*7 16*35*8 16*35*10 17*35*5 17*35*6 17*35*7 17*35*8 17*35*10 18*35*7 18*35*8 18*35*10 19*35*5 19*35*6 19*35*7 19*35*8 19*35*10 20*35*4 20*35*5 20*35*6 20*35*7 20*35*8 20*35*9 20*35*10 20*35*12 21*35*7 21*35*10 22*35*5 22*35*6 22*35*7 22*35*8 22*35*10 23*35*5 23*35*6 23*35*7 23*35*8 24*35*5 24*35*6 24*35*7 24*35*8 24*35*10 25*35*4 25*35*5 25*35*6 25*35*7 25*35*8 25*35*9 25*35*10 26*35*6 26*35*7 27*35*7 28*35*5 28*35*6 28*35*7 28*35*8 28*35*9 14*36*7 15*36*7 16*36*7 16*36*8 17*36*7 18*36*7 18*36*10 19*36*6 19*36*7 20*36*6 20*36*7 20*36*8 20*36*10 20*36*15 21*36*7 22*36*5 22*36*6 22*36*7 22*36*10 23*36*6 23*36*7 23*36*10 24*36*7 24*36*8 25*36*6 25*36*7 25*36*8 25*36*10 26*36*5 26*36*7 27*36*6 27*36*7 27*36*10 28*36*7 29*36*8 12*37*7 15*37*7 16*37*7 17*37*7 17*37*9 17*37*10 18*37*7 18*37*8 19*37*7 19*37*10 20*37*6 20*37*7 20*37*8 20*37*10 21*37*5 21*37*7 22*37*5 22*37*6 22*37*7 22*37*8 23*37*7 23*37*9 24*37*7 25*37*5 25*37*6 25*37*7 25*37*8 25*37*10 26*37*7 26*37*8 26*37*10.5 27*37*6 27*37*7 27*37*8 27*37*9 27*37*10 27*37*10.5 28*37*4 28*37*5 28*37*6 28*37*7 28*37*8 29*37*10 30*37*4 30*37*8 15*38*7 15*38*10 16*38*7 16*38*8 17*38*7 17*38*8 17*38*10 18*38*7 18*38*10 19*38*7 19*38*8 19*38*10 20*38*5 20*38*7 20*38*8 20*38*10 22*38*5 22*38*6 22*38*7 22*38*8 22*38*10 23*38*6 23*38*7 23*38*8 23*38*9 23*38*10 24*38*5 24*38*7 24*38*8 24*38*10 25*38*5 25*38*6 25*38*7 25*38*8 25*38*10 26*38*5 26*38*7 26*38*8 27*38*6 27*38*7 27*38*8 27*38*10 28*38*5 28*38*6 28*38*7 28*38*8 28*38*10 29*38*6 30*38*4 30*38*5 30*38*6 30*38*8 30*38*10 32*38*5 18*39*7 20*39*6 22*39*6 22*39*7 22*39*9 23*39*8 25*39*8 27*39*10 27*39*10.5 28*39*7 31*39*8 32*39*7 14*40*7 14*40*10 15*40*7 15*40*8 15*40*9 15*40*10 16*40*7 16*40*8 16*40*10 17*40*6 17*40*7 17*40*8 17*40*10 18*40*7 18*40*8 18*40*10 19*40*7 19*40*10 20*40*4 20*40*5 20*40*6 20*40*7 20*40*8 20*40*10 20*40*12 21*40*6 21*40*7 22*40*7 22*40*8 22*40*10 22*40*12 22*40*16 23*40*6 23*40*8 23*40*10 24*40*7 24*40*8 24*40*10 25*40*3 25*40*5 25*40*6 25*40*7 25*40*8 25*40*9 25*40*10 25*40*12 26*40*5 26*40*6 26*40*7 26*40*8 26*40*9 26*40*10 27*40*5 27*40*6 27*40*7 27*40*8 27*40*10 27*40*12 28*40*5 28*40*6 28*40*7 28*40*8 28*40*9 28*40*10 29*40*7 29*40*8 29*40*10 29.5*40*10 30*40*5 30*40*6 30*40*7 30*40*8 30*40*10 30*40*12 31*40*7 32*40*5 32*40*6 32*40*7 32*40*8 32*40*10 30*40.5*10.5 18*41*10 19*41*7 20*41*7 22*41*5 22*41*7 25*41*6 25*41*7 25*41*8 27*41*7 27*41*8 27*41*10 28*41*7 28*41*8 28*41*10 29*41*9 30*41*5 30*41*7 30*41*10 31*41*4 32*41*10 34*41*4 34*41*7 25*41.25*6 14*42*7 15*42*7 15*42*8 15*42*10 17*42*7 17*42*8 18*42*7 18*42*10 19*42*7 20*42*6 20*42*7 20*42*8 20*42*10 20*42*12 22*42*5 22*42*7 22*42*8 22*42*10 22*42*11 22*42*12 23*42*7 23*42*8 23*42*10 24*42*7 24*42*8 24*42*10 25*42*7 25*42*8 25*42*10 25*42*12 26*42*6 26*42*7 26*42*8 26*42*10 27*42*7 27*42*10 28*42*7 28*42*8 28*42*10 28*42*11 29*42*7 29*42*10 30*42*4.5 30*42*5
