SKF four-row taper roller bearings Open bearings
SKF four-row taper roller bearings are primarily produced with the TQO configuration
(➔ fig ) in the TQON design without spacer rings (➔ fig ) In the TQO configuration, there are two roller and cage assemblies arranged face-to-face. The bearings
are normally supplied with pressed steel window-type cages, although the
larger sizes may have pierced rollers and steel pin-type cages (➔ fig ).
Four-row taper roller bearings are also produced with extended inner
rings, which can serve as counterfaces for radial shaft seals (➔ fig ).
Also these bearings can be supplied without spacer rings (design TQOEN)
or with spacer rings (design TQOE). Four-row taper roller bearings that
are to be mounted with a loose fit on the roll neck, are normally supplied with a helical groove in the inner ringbore and lubrication grooves in the
side faces of the inner rings. The lubrication grooves enable lubricant to be
supplied to the contact surfaces of the inner rings and journal seating where there is a risk of wear occurring. Lubricant is stored and wear particles can be deposited in the helical grooves. This reduces wear of the roll neck.
