Explore our foundational range of heavy industrial bearings, featuring internal gear, external gear, and gearless systems designed for continuous, high-performance load handling.
A comprehensive technical analysis of model numbering structures and dynamic selection guidelines for structural engineers.
Within mechanical engineering and heavy equipment fabrication, a Double Row Ball Bearing Number functions as a technical blueprint. It does not merely signify a catalog index; instead, it defines the load configurations, ball diameter metrics, internal structures, clearances, and precision thresholds. Typically, double-row equal-diameter or unequal-diameter configurations consist of three structural rings (outer, inner, and split rings), housing two distinct tracks of steel balls separated by high-strength cages.
By dissecting a standard double row ball slewing bearing number, engineers can immediately identify:
Through Jiangsu Manchen Transmission's customized OEM / ODM services, these model numbers are tailored to precise installation dimensions, accommodating highly specialized equipment demands like wind turbine yaw drives or marine cranes.
Engineered with dual raceways to distribute static and dynamic loads across a wider surface area, surpassing single-row assemblies in heavy crane and excavation systems.
Precise machining limits axial and radial play to minimal tolerances, guaranteeing high positioning accuracy in medical equipment and industrial robotics.
Specialized surface treatments (zinc plating, black oxide, phosphating) defend the slewing rings against harsh maritime and coastal environments.

Combining raw material access, cost efficiency, and strict quality verification to serve global enterprises.
Operating out of the Jiangyin industrial corridor allows Manchen Transmission to tap directly into regional raw steel casting and forging clusters. By utilizing top-tier bearing steels such as 50Mn and 42CrMo, we guarantee our double row ball bearing structures possess ideal core toughness paired with optimal wear resistance. This localized supply integration reduces structural raw material transport times and offers significant economies of scale, directly benefiting our global customers.
Additionally, we have built long-term cooperative partnerships with many well-known domestic enterprises. With stable quality and complete after-sales services, we have won wide recognition in the market. In the future, the company will continue to focus on technological upgrading in the transmission field, and strive to provide global customers with higher-quality and more cost-effective rotary transmission products and services.
Every bearing model leaving our workshop undergoes rigorous dimension checks, hardness testing, and ultrasonic inspection. Our strict quality control systems secure full historical traceability back to the raw steel ladle. This compliance setup protects operations across European, American, and Asian industrial markets, aligning with global mechanical design regulations.
From deep-sea marine platforms to solar tracking fields, our double row configurations ensure precise torque control.
High wind resistance and compact design characteristics make our double-row configurations ideal for supporting large-scale solar arrays subject to dynamic wind pressures.
Mounted in tower cranes, mobile excavators, and foundation drills to absorb heavy tilting moments, providing reliable and stable continuous rotation.
Engineered with tight clearances and low vibration thresholds, meeting the quiet rotation specifications required by CT scanners and precision imaging mounts.
Explore our extensive inventory of external gear, internal gear, and gearless bearing models designed to fit custom configurations.
Aligning with next-generation manufacturing technology, decarbonization mandates, and automated machine intelligence.
Modern industry demands bearings that operate in aggressive environments without premature fatigue. The trend points toward low-alloy steel variants enhanced by refined heating profiles. At Manchen, we deploy medium-frequency induction heating on our raceways, hardening them to between 55 and 62 HRC. This guarantees deep hardness layers while preserving structural core elasticity to absorb rapid shock loads.
Global demand increasingly values long maintenance cycles and low friction losses. To support carbon reduction goals, we are engineering slewing structures featuring lightweight high-density seals and low-friction cages. Looking ahead, our research team is exploring integrated digital sensor ports capable of reporting grease contamination, temperature changes, and vibration anomalies directly to central control networks.
