The RKB tapered roller thrust bearing is built for equipment that carries heavy axial loads in a single direction while also tolerating moderate radial loads. Its tapered rollers and inclined raceways spread the load efficiently, which suits setups where rigidity and precision matter. MR Industrial Accessories LLC supplies this RKB series to maintenance and purchasing teams across the United States and Latin America.

RKB identifies these thrust bearings with a six-digit numeric code, for example 353020, 353024 or 353038. Each code points to one combination of dimensions and load capacity. Suffixes, when they appear, signal differences in internal design, heat treatment or sealing for a given application. Before ordering, confirm the shaft and housing dimensions together with the axial and radial loads the bearing will see.

Typical duty includes machine tool spindles, rotary tables, cranes, mining equipment, presses and heavy machinery, wherever considerable axial thrust has to be absorbed. They also appear in metallurgical, cement and oil industry operations and in power generation plants. Moderate speeds combined with high loads are their working range, and that is why they are chosen where precision and durability keep production running.

Selection comes down to load magnitude and direction, rotational speed and the surrounding environment. Alignment between shaft and housing must be precise, since these bearings do not tolerate misalignment well. Grease or oil lubrication has to be right to carry heat away and extend service life, and where dust or moisture is present, additional seals are worth evaluating. Respect the manufacturer's guidance on axial clearance and component tightening.

Bearings from different brands can be swapped when the main dimensions and load capacity line up, and codes from other manufacturers often map directly to the RKB series. For a replacement, the safest route is to send the complete code or the exact bore, outer diameter and height so the correct reference can be identified. Our team can also suggest equivalents and help you choose.
