718/97B is 40‑degree contact‑angle thin‑walled angular contact ball bearing for RV10C robot reducer. Optimized cross‑section fits RV10C internal installation space, withstands radial‑axial combined loads and overturning moment during joint swing. Standard supporting bearing for RV10C compact robot reducer units.

RV reducer precision bearings are core supporting components for industrial robot joints, consisting of three main product categories: 40° thin-section unequal-height angular contact main support bearings, miniature thin-section tapered roller bearings, and needle roller cage assemblies, fully compatible with RV6E to RV320E reducer series.

Manufactured from high-purity bearing steel with ultra-precision raceway grinding and specialized heat treatment, these bearings reliably withstand radial, axial, and tilting moment loads under frequent forward and reverse rotations. They deliver high impact resistance, exceptional rigidity, low friction torque, and accuracy grades up to P4/P5.

The ultra-thin unequal-height inner and outer ring design maximizes internal space savings within the reducer. Glass fiber-reinforced nylon cages provide high-temperature resistance and quiet operation, while proper preloading effectively controls backlash, ensuring precise robot repeatability.

Widely used in six-axis industrial robots, machine tool rotary tables, and heavy-duty automation joints. Available in comprehensive specifications with custom non-standard options to meet demanding requirements for heavy loads, high precision, and extended continuous operation.
