Decoding RKB 7236
- 72Series
- Angular contact ball bearings, 72 series. Series differ in outside diameter and width even when the bore is the same.
- 36Bore
- Bore 180 mm (36 × 5).
7236 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
RKB 7236 measures 180 mm across the bore and 320 mm across the outside diameter; its width is 52 mm (180 x 320 x 52 mm).

RKB angular contact ball bearings are built to handle radial and axial loads in one direction. The offset raceways create an oblique contact angle between the balls and raceways, which gives these bearings a higher axial load capacity than deep groove ball bearings. They are commonly found in pumps, compressors, gearboxes and machine tool spindles. MR Industrial Accessories supplies this line to customers across the United States and in several Latin American countries.
The part numbering follows the dimension series. For example, designations such as 70/500, 70/530 and 70/560 belong to the 70 series, which features a thin section and a large bore. The digits after the slash give the bore diameter in millimeters. This system lets you identify size and series at a glance, so you can match the bearing to the space and load requirements of your equipment.
In industrial settings, angular contact bearings appear in pumping equipment, screw compressors, gearboxes, and milling machine and lathe spindles. They are also used in textile machines, cranes and power transmission systems. Their capacity for combined loads suits applications where precision and rigidity matter, such as machine tool spindles and high-speed equipment.
Selecting the right angular contact bearing means reviewing the magnitude and direction of the loads, the rotation speed and the operating environment. During mounting, pay attention to alignment and axial clearance, which can be set by installing bearings in pairs. Proper lubrication, with grease or oil, helps extend service life. Seals or shields keep contamination out, though an open design may be chosen for high-speed applications to help with heat dissipation.
Equivalent bearings exist across brands, but suffixes and tolerances can vary from one manufacturer to another. When you need a replacement, check the main dimensions and load conditions. MR Industrial Accessories can help you find a compatible option, whether you provide a part number from another brand or an unidentified part.

Frequently asked questions
- RKB 7236 bearing: what are its dimensions?
- RKB 7236 measures 180 mm across the bore and 320 mm across the outside diameter; its width is 52 mm (180 x 320 x 52 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 7236.
- What does the designation 70/500 mean in an angular contact bearing?
- The prefix 70 indicates the dimension series, which in this case is a thin section. The number 500 after the slash is the bore diameter in millimeters. This nomenclature helps you identify the size and series to select the right bearing for your space and loads.
- What is the difference between an angular contact bearing and a deep groove ball bearing?
- An angular contact bearing has offset raceways, which allows it to withstand axial loads in one direction and combined loads. A deep groove ball bearing mainly handles radial loads and limited axial loads. That is why angular contact bearings are used where axial loads are significant.
- How can I request a quote for an RKB angular contact bearing?
- Send us the part number or size you need on WhatsApp or by email. Our team replies promptly. If you have a part number from another brand, we can also suggest a compatible alternative.
