Tapered roller bearings from RKB are supplied as two separate pieces: the cone, which holds the rollers and the cage on the inner race, and the cup, which is the outer race. Because each bearing takes radial and axial force in a single direction, they normally work in opposed pairs. Gearboxes, wheel hubs and transmission assemblies are typical places where this combination of stiffness and load capacity is needed.

The letters BT1B at the start of the reference mark the tapered roller family, and the digits that follow act as the internal size code. Three references that come through regularly are BT1B 328833, BT1B 332808 and BT1B 443786. For a replacement, the safest route is to read the full code stamped on the cone or the cup, or to take it from the machine drawing, rather than working from a partial number.

Food processing, metallurgy, cement and mining operations use this type of bearing, along with equipment such as conveyors, mills, pumps, fans and road machinery. Speed reducers, drive shafts and support rollers are common mounting points. Where the load direction shifts during operation, or where axial force is significant, the paired arrangement handles what a single-row bearing cannot.

Selection comes down to radial load, axial load, running speed and the conditions around the bearing. Alignment at mounting has to be accurate, and lubrication, whether grease or oil, must match the duty. Bearings are available open or with seals, and internal clearance should stay inside the manufacturer's recommended range so the bearing does not run hot or noisy. Using a press and the correct fitting tools protects the races during installation.

Cross-referencing between brands is routine when a replacement is needed. Tapered roller bearings are defined by their series number plus three main dimensions: bore, outer diameter and width. When the original code does not line up with another maker's numbering, equivalence tables or direct measurement of the part will get you there. If you send us the BT1B code and series number on WhatsApp, or the measurements, we will reply with a quote and point you to the reference that fits your equipment.
