What is a Single - Row Ball Profile Bearing?
Single - Row Ball Profile Bearings are generally used in light-load applications and are produced with a four-point contact ball system. They are classified into three main groups: bearing, internal gear, and external gear. In addition to standard sizes ranging from Ø518 mm to Ø1600 mm, custom dimensions can be manufactured according to your design requirements.
Single - Row Ball Profile Bearings
Bearing
Single -Row Ball Profile Bearings deliver high load capacity, low friction, and extended service life—making them indispensable for industrial systems. Reel Makina-manufactured bearings enhance efficiency in CNC machinery, conveyor systems, industrial robots, and slewing ring applications. Our bearings offer quiet operation, shock absorption, and ease of maintenance, maximizing machine performance.
At Reel Makina, we manufacture bearings with precise tolerances and high-quality standards. Every bearing undergoes 100% inspection and can be custom-produced up to 5000 mm
Internal Gear
Internal gear slewing rings excel in compact systems where external space is limited. Commonly 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 custom-designed tooth profiles, low backlash tolerances, and precise heat treatment processes. Frequently selected for defense, tunnel boring machines, and marine projects, these products offer superior performance against environmental challenges—tailored to each sector’s requirements with full technical support.
External Gear
External gear slewing rings provide high torque transmission and easy integration into external mechanisms for large-scale equipment. Widely used in excavators, cranes, concrete pumps, and heavy industrial machinery, these designs deliver operational strength and efficiency. Reel Makina’s external gear bearings offer a flawless solution for heavy-duty industrial loads.
Our external gear systems feature precisely milled tooth profiles and high surface hardness for long service life. With production precision exceeding industry standards, we serve applications from port cranes to defense systems. Every bearing undergoes rigorous quality control before delivery.
