Spherical roller bearings add code suffix used to identify the spherical roller bearing certain characteristics, including SKF spherical roller bearings, open design, sealed spherical roller bearings, mechanical vibration bearings: C2: radial clearance smaller than normal group C3: radial clearance greater than Normal C4: radial clearance than C3C5: radial clearance than C4C08: rotational accuracy to ISO tolerance class 5C083: C08 C3C084: C08 C42CS: bearings on both sides with a steel skeleton hydrogenated nitrile rubber (NBR) contact seals. Outer ring with lubrication groove and three lubrication holes, covered by a plastic band.
Spherical roller bearings 2CS2: bearings on both sides with a steel skeleton Viton (FPM) contact with the seal. Cylindrical outer ring with lubrication groove and three lubrication holes, covered by a plastic band. 2CS5: bearings on both sides with a steel skeleton of hydrogenated nitrile rubber (HNBR) contact seal. Other 2CS2 same HA3: hardened inner ring K: tapered bore, taper: 1:12 K30: tapered bore, taper: 1:30 P5: dimensional accuracy and rotational accuracy to ISO tolerance class 5P6: dimensional accuracy and rotational accuracy to ISO tolerance Level 6P62: P6 C2VA405: vibrating machinery bearings, hardened cage VA406: VA405 and an inner hole with a polytetrafluoroethylene (PTFE) coated VE552 (E): average published outer side with three threaded holes to connect the lifting device; E represents bearings with eyebolts VE553 (E): the VE552 same, but both sides are threaded holes VG114: hardened pressed steel cage VQ424: rotational accuracy than C08W: no outer lubrication groove and lubrication hole.
Spherical roller bearings W20: outer ring with three lubrication holes W26: inner ring with six lubrication hole W33: outer ring with lubrication groove and three lubrication holes W64: marked with solid oil bearing W77: W33 identical with, but the lubrication hole even stopper W513: W26 W33235220: hardened inner ring, bore with a spiral groove.
