For fixed end bearings NCL...V type:
Non-supporting cylindrical roller bearings with no ribs on the outer ring but with double locking rings.
This kind of bearing has no support frame; the number of rollers is large; other cylindrical roller bearings with the same scale can accept larger radial loads; but the limit rotation speed is lower. The inner and outer rings of the bearing are not separated; Can not be separated from the device; the axial displacement of the two directions that can constrain the shaft or the casing is within the axial clearance limit of the bearing.
NB type:
Cylindrical roller bearing without ribs.
The inner and outer rings of the bearing have no ribs; the outer ring has smooth oil holes; the inner ring, the outer ring and the holding frame with a full set of rollers can be separated from the device; the axial displacement of the bearing or the outer casing cannot be restrained; the axial direction cannot be accepted; Load.
NJ...V-type inner ring has a single-ribbed and non-supporting cylindrical roller bearing. This type of bearing has no support; the number of rollers is large; compared with other cylindrical roller bearings of the same external dimensions, there is a large radial load. Talent; but the limit speed is low; does not constrain the axial displacement of the shaft or the casing; can not accept the axial load.
NCF...V-type outer ring has a single-ribbed non-sticking centering short cylindrical roller bearing. This type of bearing has no holding frame; it is filled with rollers; it is comparable to other cylindrical roller bearings of the same scale; it can accept larger diameters. Toward the load; but its limit speed is lower.
The bearing can constrain the axial displacement of the shaft or the casing in both directions within the axial clearance limit of the bearing.
...N type (with stop groove bearing)
Some single row cylindrical roller bearings have a retaining groove on the outer ring; the rear code is indicated by "N". The bearing is axially positioned in the bearing housing by the retaining ring; the axial fastening of the bearing in the housing hole is simplified; The hole can be made into a through hole; then the axial dimension of the part is reduced.
Double row cylindrical roller bearings:
NN type:
The inner ring has a rib; the outer ring has no ribs. It can be separated from the outer ring and the inner component of the device; the axial displacement of the shaft or the outer casing is not constrained; the axial load cannot be accepted; and the single row cylindrical roller bearing is the same as the radial dimension; Can accept large radial loads.
Compact layout; deformation when receiving load. Despise Kamakura fashion hustle С.
NN...K type:
The layout is the same as the NN type; only the inner hole of the bearing is tapered; it is easy to adjust the radial clearance of the bearing; and the assembly and disassembly is convenient. The spindle of the machine tool is mostly used for this type of bearing; it is mounted on the cone shaft; The amount adjusts the radial clearance.
NNU type, NNU...K type:
The outer ring has a rib; the inner ring has no rib. There are two kinds of cylindrical holes and tapered holes. The axial displacement of the shaft or the outer casing is not constrained; the axial load cannot be accepted; and the single row cylindrical roller bearing with the same radial dimension is compared; Can accept large radial loads.
NNCF type:
The inner ring has three ribs; the outer ring has a rib; the axial direction can be positioned in one direction. The outer ring is provided with a fixing ring on the other side of the rib; so that the bearing adheres to one body.
NNCL type:
The inner ring has three ribs; the outer ring has no ribs; the two sides have a stop ring to become a non-detachable bearing.
NNCS type:
The inner ring has three ribs; the outer ring has no ribs; the center of the outer ring has a middle lock ring; it becomes a non-detachable bearing. It has a certain axial displacement of the shaft and the bearing seat; it can be used as a free end bearing.
Four-row cylindrical roller bearings Four-row cylindrical roller bearings can accept large radial loads and impact loads; high machining accuracy; suitable for high speed.
The inner ring raceway surface and the roller surface can be ground together after the inner ring is pressed into the roller diameter; it is beneficial to improve the rolling precision; and the bearing clearance of the bearing can be adjusted freely.
Mostly used in the work rolls or backup rolls of cold, hot rolling mills, blanking machines, etc.; but can also be used in other applications.
FC: double outer ring; single inner ring; inner ring without rib FCD: double outer ring; double inner ring; inner ring without rib FCDP: double outer ring; outer ring as long as middle rib but with flat ring; double inside Circle; inner ring without ribs â– The basic dimensions of scale-size ZWZ cylindrical roller bearings are listed in the scale data sheet;
Inner diameter scale: 25mm ~ 1900mm
Outer diameter scale: 52mm ~ 2300mm
Width scale: 13mm ~ 400 mm
â—† Public service ZWZ produces single-, double-, and four-row cylindrical roller bearings of P4 class or lower; together with special-grade SP and UP double-row cylindrical roller bearings for machine tool spindles.
â–² The standard product of the radial clearance single row cylindrical roller bearing has a fundamental set of radial clearance, and can also supply C3, C4 group clearance.
The double row cylindrical roller bearing specification product has C1 group clearance, the cylindrical hole can also supply C2 and C3 group clearance, and the tapered hole bearing can also supply C2 group clearance.
The four-row cylindrical roller bearing specification product has a C3 group clearance; together, it can also supply other clearance group products.
The standard clearance value can be found in the preamble table. Bearings with radial clearance greater or less than the specification value can also be produced according to user requirements.
★ Persistent single-row cylindrical roller bearings are mostly made of car-made solid body holders, stamping holders, nylon frames, etc. Double row cylindrical roller bearings are mostly made of brass brackets; sometimes they can also be supplied with nylon brackets. Roller bearings are mainly used to make brass brackets for the car; for larger scales, it is advisable to use the car body to support the frame.
Stick to the code name as follows:
1. When using the stamping frame; stick to the rear code of the rack to mark J; if the layout of the various stamping frames is different; use J, J1, J2 in sequence. . . Indicates that when the trough is selected, the post-coded CJ is attached to the frame.
3, select the brass entity to adhere to the frame; adhere to the rear post code M,
4. When the outer diameter of the bearing is D>400mm; use the steel body to adhere to the frame; adhere to the rear post code without marking; but if it is for internal and external guidance, it should mark the corresponding post code and guiding method together ( The outer boot is A; the inner boot is B).
Double row cylindrical roller bearings use brass solid body to adhere to the frame.
â– Equivalent dynamic load when only radial load is accepted; P = Fr
★ Equivalent static load P0r = Fr
Cylindrical roller bearings have both inner and outer rings with ribs or retaining rings; they also accept a certain amount of axial load when receiving radial loads. The axial load at this time depends on the end face of the roller. , the bearing capacity of the rib, the smooth condition and the rotational speed, etc.
