Rolling Mill Bearing 37244 For Roll Neck 220x310x226mm For Steel Plant
We/JINHANG Precision Bearing produces special executions of TQO made of four single cups and two double cone assemblies (design without spacers).
Most of TQO and TQI four row taper roller bearings are manufactured with inch dimensions as per American AFBMA 19/1974 and as per We/JINHANG Precision Bearing standard practice, dimensional and running accuracy grade is in accordance with class 2 or 4.
TQO and TQI configuration (face-to-face or back-toback arangement),
• sealed and open bearings,
• bearings with or without extended inner rings,
• bearings with cylindrical or tapered bore,
• bearings with and without spacer rings.

TQI design Open bearing, pairs of roller and cage assemblies arranged back-to back.
four-row taper roller bearings are primarily produced with the TQO configuration in the TQON design without spacer rings 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 Four-row taper roller bearings are also produced with extended inner rings, which can serve as counterfaces for radial shaft seals .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 ring bore 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.
| Component |
Two double cones, two single cups and a double cup with a cone spacer and two cup spacers. Spacers have slots or holes for lubrication. Cone spacers are hardened to reduce face wear. Numbered serially to assure correct installation sequence.
|
| Details |
TQO bearings are directly mounted and comprised of two double inner races, two single and one double outer race, with an inner race spacer and two outer race spacers. Slots in the inner race spacer permit lubricant to flow from the bearing chamber to the roll neck. The inner race spacers are hardened to minimize face wear. |
| Application |
heavy plate mills _ hot strip mills _ cold rolling mills _ skin pass mills _ roughing mills _ universal beam mills _ rod, bar and wire mills |
| Material | GCr15SiMn ,G20Cr2Ni4A( carburizing steel) |
| Packing |
