SKF needle roller bearing is a cylindrical roller bearing, although it has small cross section, but it has very high load capacity.
SKF needle roller bearings are cylindrical roller bearings, cylindrical roller compared with its diameter is more slender. Although these imported SKF bearings have small cross section, they have very high load capacity, so they are very suitable for bearing configurations with limited radial space.
SKF needle roller bearings have a variety of designs and various sizes, including:
SKF needle roller and cage assembly
SKF punching outer ring roller bearing
Open end locking and closed end
Full roller
Needle bearing for machining bearing ring with SKF belt machine
With or without flanges
Locking and without inner ring locking
With sealing, locking and locking, locking and without inner ring
SKF pair of needle roller bearing
SKF needle roller bearing with inner ring lock
SKF universal joint bearing lock
SKF combined needle roller bearing
SKF needle roller thrust bearing
SKF needle roller and cage assembly
SKF rollers and cage components are fast mounting independent components. They are excellent options for bearing configurations requiring very high rigidity and high load bearing capacity. If the shaft and bearing hole can be used as raceway, the needle roller and cage assembly only need very small radial space.
SKF provides single row and double row needle roller and cage assembly design. Their characteristics are simple and firm, and the roller guides accurate and good performance in the cage.
Other SKF needle roller and cage components, SKF's many needle roller and cage components products are only listed in the SKF bearing model table. SKF also provides other sizes and cage assemblies that are different from the standard design. For example, the assembled needle roller cage assembly can be used in the application of raceway concave shaft.
The type suffix of some characteristics of SKF needle roller and cage assembly is explained as follows:
DS: the spliced needle roller and the cage assembly
/SORT: the needle tolerance grade of needle roller and cage assembly, followed by the actual limit, the unit is micron, such as /SORT-2-4
TN: glass fiber reinforced polyamide 66 mold holder
VG052: polyethersulfone (PES) retainer
ZW: double row needle roller and cage assembly (double row cage).
SKF punching outer ring roller bearing
SKF needle punching bearing for outer ring, as the name suggests, is a needle roller bearing with open end or closed end deep drawing thin outer ring. Its characteristics are low section height and high carrying capacity. The punching outer ring roller bearing is usually used in the bearing seat holes that can not be used as the raceway of the needle roller and the cage assembly, but it also requires a very compact and economical application of the bearing configuration.
SKF provides a variety of punching outer ring roller bearings. Include：
SKF with open end punching outer ring roller bearing
SKF with closed end punching outer ring roller bearing
Roller bearing with an opening full roller punching outer ring
Imported SKF with closed end punching outer ring roller needle bearings is suitable for bearing configuration at shaft ends. The shape design of closed ends is suitable for applications with small axis guidance force. Needle roller bearings for stamping outer ring are usually used directly on the shaft. However, under the condition that the shaft can not be hardened and lapping, the needle bearing of the punching outer ring can be used in conjunction with the inner ring.
These SKF imported bearing hardened steel sheets, stamping outer rings, needle rollers and cage assemblies are made of non detachable components. The space for storing lubricants is large, and a longer lubrication interval can be obtained.
The type suffixes of some characteristics of the needle roller bearing for SKF punching outer ring are explained as follows:
AS1: a lubricating hole in the outer ring
RS: a contact seal on one side of the bearing
.2RS: double side encrypt seal, needle punched outer ring needle bearing with open end.
TN: glass fiber reinforced polyamide 66 mold holder
The needle bearing of the imported SKF belt machine bearing ring
The imported SKF needle roller bearing with carbon chromium bearing steel machined bearing ring has a very small cross section, and its bearing capacity is very high relative to its size. These bearings can be provided with or without inner rings according to the application situations.
If you can harden and grind the shaft, the needle roller bearing without inner ring is an excellent choice for compact bearing configuration. Because no inner ring is needed, the shaft diameter can be greater, so the strength and stiffness are higher. The axial displacement of the shaft relative to the bearing seat is limited only by the width of the raceway on the shaft. By machining the shaft raceway machine to the appropriate size and shape accuracy, it is possible to create a bearing configuration with improved operation accuracy.
SKF provides several design and size needle roller bearings with machined bearing rings.
Outer ring flange: sealed or not sealed, and with or without inner ring.
Outer ring without flange: without sealing and with or without inner ring.
The type suffix representing the characteristics of SKF needle roller bearings is explained below.
C3: the radial internal clearance is greater than the normal value
C4: radial internal clearance is greater than C3
H: without inner ring needle roller bearings, with reduced inner diameter tolerance (less than roller), followed by tolerance limit, unit of micron, such as H+27+20
IS1: a lubricating hole in the inner ring
P5: Dimensions and running accuracy are ISO tolerance 5 level specifications (above P6).
P6: size and running accuracy is ISO tolerance 6 level specification (higher than conventional level).
RS: NBR (NBR) contact seal, bearing with or without steel plate reinforcement.
2RS: there are RS contact seals on both sides of the bearing
TN: glass fiber reinforced polyamide 66 injection molding cage, concentric with rolling body.
