RKB bearings for concrete mixer gearboxes 🇲🇽
In 2019, RKB spherical roller bearings with a WOR (wide outer ring) design were first supplied as spare parts for concrete mixer gearboxes used by leading manufacturers in the Mexican cement sector, replacing earlier solutions.
The RKB steel cage design was soon preferred over polyamide alternatives, receiving positive feedback from users.
To date, almost 1,500 RKB spherical roller bearings with a WOR design have been delivered for Foton and McNeilus concrete mixer fleets. CRM Mircea Despa
These mixers are equipped with Danfoss gearboxes that use a specially engineered RKB bearing, which increases misalignment tolerance, sustains higher loads at low speeds, and reduces cracking risk through a specialized heat treatment process.
