Double-row tapered roller bearings in the RKB TQOS line are built for shafts that see radial and axial forces at the same time, in either direction, and that need to stay rigid and well centered. Gearboxes, rolling mill stands, spindles and similar precision assemblies are typical homes for these units. MR Industrial Accessories supplies them to customers throughout the United States and in several Latin American countries, quoting from the part number you send by WhatsApp or email.

Reading the code is the first step in ordering the right bearing. Every designation in this line opens with the letters TQOS and continues with a six-digit block, for example TQOS 328278, TQOS 328468 or TQOS 328546. That block is the size and variant identifier, not a production lot or a date. For a replacement, copy the full part number from the drawing or from the marking on the old bearing and send it over; the quote is then prepared against that exact reference.

You will find these bearings where shafts carry combined loads: gearboxes and gear units, rolling mills, road machinery, mills, presses and machine tool spindles. Steel plants, cement plants, paper mills, oilseed plants and mining operations rely on them where loads are heavy and duty cycles are demanding. Lifting and conveying equipment exposed to impact and vibration also uses this design.

Selection comes down to three things: internal clearance, sealing arrangement and the lubrication the equipment calls for. Double-row tapered rollers are generally fitted on both the shaft and the housing, and alignment matters so that the two rows share the load evenly. Grease or oil may be specified depending on the machine, while the seal type determines whether dust, water or chips can reach the rolling elements. At mounting, check the tightening and confirm the assembly rotates freely with no hard spots.

Bearings from various makers carry their own designations for comparable duties, so an unfamiliar number does not automatically rule out a match. When a customer provides a part number from another brand or an unmarked part, the comparison looks at dimensions, mounting style and load capacity. Interchangeability is never automatic: two bearings can share the same outer dimensions yet differ in clearance, sealing or heat treatment. A technical check before ordering helps avoid premature failure and unplanned downtime.
