Used to identify the self-aligning roller bearings certain characteristics suffix is explained below. This does not include bearings used to identify (and cage) designed suffix, such as CC, or E.
C2 Radial internal clearance smaller than normal level
C3 radial internal clearance greater than normal level
C4 Radial internal clearance greater than C3
C5 Radial internal clearance greater than C4
C08 the increased running accuracy to ISO tolerance class 5
C083 C08 + C3
C084 C08 + C4
2CS bearing on both sides of the strip skeleton nitrile rubber (NBR) contact seal. Outer ring with annular groove and three lubrication holes covered with a polymer band. According to the table, in order to limit pressure grease.
2CS2 bearing on both sides of the strip skeleton Viton (FPM) contact seal. Outer ring with annular groove and three lubrication holes covered with a polymer band. Polyurea grease with high temperature
2CS5 bearing on both sides of the strip skeleton hydrogenated nitrile rubber (HNBR) contact seal. Other specifications same with 2CS2
HA3 hardened steel inner ring
K Tapered bore, taper 1:12
K30 tapered bore, taper 1:30
P5 dimensions and running accuracy to ISO tolerance class 5
P6 dimensions and running accuracy to ISO tolerance 6 standard
P62 P6 + C2
VA405 with vibration applications for surface hardening of the bearing cage
VA406 VA405 and PTFE-coated hole
VE552 (E) one side of the outer ring with three equally spaced threaded holes to use lifting block; E indicates the bearing to provide appropriate eyebolt
VE553 (E) and VE552 same, but with the screw holes on both sides
VG114 hardened pressed steel cage
VQ424 running accuracy better than C08
VT143 under extreme pressure grease filling tables use.
W without outer annular groove and lubrication hole
W20 outer ring with three lubrication holes
W26 lubrication hole in the inner ring with six
W33 outer ring with an annular groove and three lubrication holes
Plug-W33 W77 lubrication hole
W513 W26 + W33
235,220 hole with a spiral groove hardened steel inner ring
