SKF Swedish bearing front and rear code (1)
| /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089'; |
B The touch angle is 40 degrees.
The CC touch angle is 12 degrees.
The CD touch angle is 15 degrees.
BE BE bearing with a touch angle of 40 degrees; steel ball is enlarged; glass fiber reinforced nylon 6.6 cage.
Double row angular contact ball bearing A Specification of bearing with outer diameter less than or equal to 90 mm; no ball gap; glass fiber reinforced nylon 6. 6 cage.
E bearing has a ball-filling port on one side; it can hold more steel balls; therefore, it has high radial and axial bearing capacity.
Spherical roller bearings CAC; ECAC; CA; ECA These are depicted for large-scale bearings; the rollers are symmetrical.
CC; C; EC such bearing roller is symmetrical; the inner ring has no ribs.
E is SKF's selection of the latest specifications. The outer ring of the E-type bearing has an oil groove and three oil holes; then the rear code must be added with W; to show the difference.
Cylindrical roller bearing B bearing uses externally treated roller (full complement roller bearing).
B4 bearing ring outer surface and roller appearance are treated (full complement roller bearing).
The internal shape of the EC bearing has been improved; the bearing capacity is high; the rib and roller end face have excellent touch and smooth conditions; and can accept high axial load.
(2) Externally depicted CA; CB; CC universal matched single-row angular touch ball bearing; optional (series; face-to-face or back-to-back) pairing device. Back-to-back or face-to-face placement; axial device front internal clearance to normal value ratio: small (CA); normal (CB); larger (CC).
-2F Spherical ball bearings with dust ring on both sides.
-2FF outer spherical ball bearing with combined dust ring on both sides.
G Universal pairing single row angular contact ball bearings. When placed face to face or back to back; there is a certain preload of the device in the bearing.
GA face to face; when placed back to back; there is a lighter preload in the bearing.
GB face to face; when placed back to back; medium preload in the bearing.
GC face to face; when placed back to back; heavy preload in the bearing.
K tapered hole; taper 1:12.
K30 tapered hole; taper 1:30.
-LS bearing has a touch seal on one side; there is no seal groove on the inner ring.
-2LS bearing has LS seal on both sides.
N bearing outer ring has a stop groove.
The NR bearing has a retaining groove on the outer ring and a snap ring.
There are two diametrically opposite notches on the N2 outer ring chamfer.
PP bearing (support roller bearing; cam follower bearing) has a touch seal on both sides.
The RS bearing (needle bearing) has a synthetic rubber or polyurethane touch seal on one side.
-RS1 bearing has a lining steel synthetic rubber touch seal on one side.
-2RS1 bearing has RS1 seal on both sides.
-2RS bearing (needle bearing) has RS seal on both sides.
-RZ bearing has a low-conflict seal on one side of the steel-lined synthetic rubber.
-2RZ bearing has RZ seal on both sides.
X 1. The fundamental scale has been revised to fit the ISO specification, 2. Cylindrical rolling surface (support roller bearing; cam follower bearing).
Z bearing has a dust cover on one side (non-conflicting seal).
-2Z bearing has a dust cover on both sides.
-ZN bearing has a dust cover on one side; there is a stop groove on the outer ring on the other side.
-2ZN bearing has a dust cover on both sides; the outer ring has a stop groove.
-2NR with -ZN; and with a snap ring.
-2ZNR with -2ZN; with a snap ring.

According to different materials, it can also be called iron wire ginning net, galvanized ginning net, white steel ginning net, black steel ginning net, stainless steel ginning wire, wire ginning net, copper clad steel ginning net. Depending on the application, the ginning nets can also be used as ore sieve ginning nets, pig ginning nets, barbecue ginning nets, granary ginning nets, and decorative ginning nets. According to the form, it can also be called ginning net, embossed ginning net, ginning net. The ginning net is a square mesh made by ginning and ginning and then passing through a new type of weaving machine to wire of different materials and different specifications. It has a variety of uses for wire mesh products.
The crimped net adopts the weaving method of first bending and then forming, including: two-way wave isolation bending, flat top bending, two-way bending, lock bending, first rolling and then weaving
Crimped Mesh material
Stainless steel wire, iron wire, black steel wire, lead wire, white steel wire, brass wire, copper wire and other non-ferrous metal wires.
