Decoding RKB 32015

320Series
Tapered roller bearings, 320 series. Series differ in outside diameter and width even when the bore is the same.
15Bore
Bore 75 mm (15 × 5).

32015 is the standard ISO basic designation, which sets the bearing type, series and bore.

Description

RKB 32015 measures 75 mm across the bore and 115 mm across the outside diameter; its total width is 25 mm (75 x 115 x 25 mm).

For operations that combine radial and axial forces in one bearing position, RKB tapered roller bearings are a practical choice. The tapered geometry of races and rollers creates linear contact, which distributes the load across the assembly. Gearboxes, wheel axles and industrial machinery are typical homes for these bearings, where rigidity and precision matter. MR Industrial Accessories LLC supplies them and can help you match the right reference to your application.

Reading the part number helps you narrow down the options. In the 320 series, a designation like 320/22 or 320/28 tells you the bore size in millimeters—22 mm and 28 mm respectively—while the series number reflects the section and capacity. The 322 series, for instance 322/28, offers a higher capacity. Other references such as 255-417054 or 418/414 combine cone and cup numbers for specific assemblies. If you need to confirm which series fits your shaft, send the code over and our team will review it.

These bearings appear in automotive, metallurgical, food processing and mining environments. You will find them in gearboxes, reducers, transmission shafts, conveyor rollers and agricultural equipment. Their ability to handle combined loads and their stiffness suit applications with tilting moments, including earthmoving and oil industry machinery.

Selection depends on the radial and axial load, the speed and the conditions on site. During mounting, alignment must be precise and axial clearance set correctly using nuts, washers or shims. Grease or oil lubrication is chosen according to the application. Sealing is critical to keep contaminants out, so radial shaft seals or labyrinth seals are recommended. Proper installation supports a longer bearing service life.

Interchange between brands is possible when dimensions and load capacity align. Tolerances and contact angle can differ from one manufacturer to another, so those points deserve a check. If you have a part number from another brand, we can point you to a compatible option. Reviewing the technical data before replacing a bearing is always a good practice.

Frequently asked questions

RKB 32015 bearing: what are its dimensions?
RKB 32015 measures 75 mm across the bore and 115 mm across the outside diameter; its total width is 25 mm (75 x 115 x 25 mm). Those are the boundary dimensions standardized in ISO 355 for basic designation 32015.
What does the designation 320/28 mean?
It identifies a tapered roller bearing in the 320 series with a 28 mm bore. The series number indicates the section and load capacity. Ask us on WhatsApp for more details.
How is a tapered roller bearing mounted?
Align the shaft and housing, then set the axial clearance with nuts or shims. Lubricate as specified and check the sealing to keep contaminants out. Poor mounting can shorten bearing life.
Can I replace a bearing from another brand with an RKB one?
Yes, if dimensions and load capacity match. Check tolerances and contact angle, as they may vary. Send us the original part number by WhatsApp or email and we will help you find the right equivalent and quote it.
