What is a Single-Row Ball Profile Bearing?
Our Slewing Ring solutions with a single ball raceway feature a four-point contact geometry, carrying axial, radial, and tilting moment loads in a single stage. In addition to standard diameters from Ø486 mm to Ø1600 mm, custom production is available up to Ø5000 mm. Compared to double-row designs, the single-row configuration offers 20% lower body height and lighter weight, providing space savings in compact machinery. Options include internal gear, external gear, or gearless designs, offering mounting flexibility for mobile cranes, packaging lines, robotic turntables, and medical gantry applications. The optimized ball pitch reduces friction, lowers energy consumption, and extends maintenance intervals.
Single-Row Ball Profile Bearing
Bearing
Single-Row Ball Profile Bearings offer high load capacity, low friction, and long service life, making them indispensable in industrial systems. Bearings manufactured by Reel Makina deliver efficiency in CNC machines, conveyor systems, industrial robots, and slewing applications. Our bearing systems provide quiet operation, impact absorption, and easy maintenance to maximize machine performance.
At Reel Makina, we produce bearings with precise tolerances and to the highest quality standards. Every bearing undergoes 100% inspection and can be custom-produced up to Ø5000 mm. Trusted in numerous projects within the food, energy, defense, and automation industries, our products add strength and continuity to your operations.
Internal Gear
Internal gear Slewing Rings stand out for their compact design in systems with limited outer space. Widely used in wind turbines, crane systems, tower platforms, and defense applications, internal gears ensure high torque transmission and secure positioning. Reel Makina’s internal gear solutions deliver durability and long-term performance.
Our internal gear bearings are manufactured with application-specific tooth profiles, low backlash tolerance, and precise heat treatment processes. Commonly preferred in defense, tunnel boring machines, and marine projects, our products perform exceptionally under challenging environmental conditions. They are provided with tailored technical support for every sector.
External Gear
External gear Slewing Rings offer high torque transmission and easy integration with external mechanisms in large-scale equipment. Frequently used in excavators, cranes, concrete pumps, and heavy industrial machinery, they deliver efficiency and robustness in operation. Reel Makina’s external gear bearings provide flawless solutions for heavy industrial loads.
Our external gear systems feature precisely milled tooth profiles and high surface hardness for long-lasting operation. With manufacturing precision beyond standard requirements, they serve a wide range of applications from port cranes to defense systems. Each bearing undergoes stringent quality control before delivery.
