RKB ball bearings

The ball bearings (BBs) manufactured by RKB come in many designs, dimensions and series. They are conceived to withstand combined loads and high speeds, covering most requirements in a number of standard and special industrial applications. All RKB BBs are made from high quality materials and special heat treatments
for superior performance.
Available in single and double row con guration, in open or sealed version, they are low-maintenance, which makes them an irreplaceable cost-effective solution in many cases. For large size BBs, RKB can also apply Bainite Hardening Treatment (HB) and High Temperature Dimensional Stabilization (S) on rings and balls. The bearing dimensional and running accuracy conforms to ISO/ABMA/
GOST speci cations.

Angular contact ball bearings

The angular contact ball bearings (ACBBs) produced by RKB are used in a wide array of machines where combined loads, high speeds and runout accuracy are required. Available in single or double row con guration, they can be manufactured with different types of cage (machined brass, pressed steel or polyamide) and dimensional precisions.
Single row ACBBs can be directly paired by RKB in face-to-face (DF) or back- to-back (DB) con guration, depending on load conditions, presence of tilting moments and misalignment magnitude in the application.

RKB cylindrical roller bearings

The cylindrical roller bearings (CRBs) manufactured by RKB are produced in many designs, dimensions and series, to withstand heavy radial loads and medium speeds, covering most of the requirements in a variety of standard and special industrial applications. All CRBs manufactured by RKB offers the highest load rating capacities, improved internal geometry, high quality materials and special heat treatments for superior performance. RKB CRBs are available with cylindrical or tapered bore in single, double or multi row con guration. Depending on application requirements, RKB Bainite Hardening Treatment (HB) and High Temperature Dimensional Stabilization (S) can be applied on bearing rings and rollers. The bearing dimensional and running accuracy conforms to ISO/ ABMA/GOST speci cations.

Double row cylindrical roller bearings

With a wide range of executions of double row cylindrical roller bearings (DRCRBs), RKB is able to ful ll any requirement in demanding applications such as large size gearboxes, machine tools, grinding mills and crushers.
To ensure superior performance, RKB double row cylindrical roller bearings are manufactured from high quality special steels, heat treated in optimized automatic lines.
With improved internal geometry and pro le, DRCRBs can withstand high radial loads within a narrow cross section.
