RKB TQOS series tapered roller bearings are double-row units that handle radial and axial loads in both directions, with the rigidity demanded by precision assemblies. They are used in gearboxes, rolling mill stands, spindles and equipment where the shaft must stay firm and centered. MR Accesorios Industriales sells them in Buenos Aires, Argentina, and quotes them by WhatsApp with the exact part number.

The designation of this line starts with the letters TQOS followed by a six-digit number, as in TQOS 328278, TQOS 328468 or TQOS 328546. That numeric block identifies each size and variant in the series: it is not a batch code or a date, but the reference that defines the assembly. So, to order the correct replacement, the most practical thing is to send the complete part number exactly as it appears on the drawing or on the old part. With that data, at MR we quote the corresponding bearing.

This type of bearing appears in equipment with shafts subjected to combined loads: gearboxes and gear units, rolling mills, road machinery, mills, presses and machine tool spindles. In Argentine industry it is found in steel plants, cement plants, paper mills, oilseed plants and in the mining sector, where the load is high and the assembly must withstand demanding cycles. It is also used in lifting and conveying equipment that works with impact and vibration.

To choose correctly, you need to look at internal clearance, the type of sealing and the intended lubrication. Double-row tapered rollers are usually mounted with a fit on the shaft and in the housing, and they need careful alignment so that both rows share the load. Lubrication can be grease or oil depending on the equipment, and the sealing defines whether the bearing is protected against dust, water or chips. During mounting, it is advisable to check the tightening and verify that the assembly turns without hard spots.

Bearings from different manufacturers with their own designations for equivalent functions coexist in the market. When the customer brings a part number from another brand or an unidentified part, dimensions, mounting type and load capacity are compared to find the right equivalent. Interchangeability between brands is not automatic: two bearings may share outer dimensions and differ in clearance, sealing or treatment. That is why prior technical verification prevents premature failures and plant downtime.
