# Three Row Roller Slew Ring Bearings Supplier

+91 9503911711 kaustubh@kavitsubearing.com Icon-facebook Linkedin Instagram Youtube Three Row Roller Slew Ring Bearing Home Products Three row roller slew ring bearing ” We are proud to be one of India’s few Three row roller slew ring bearing manufacturers who have developed these products indigenously. We can guarantee that our Three row roller slew ring bearing match global standards and are competitively priced. “ Three row roller slew ring bearing comes in three different parts of ring, upper race, lower race and inner/outer race. The loads coming on each row is different and this is the basic selection criteria for the rollers. Three row roller slew ring bearing is able to carry different loads at the same time, and their load carrying capacity is larger than that of a similar configuration of ball bearing. Since such type of bearings have bigger radial and axial dimensions, these bearings can be used where very heavy loads have to be slewed. The material that is generally used in these three row roller bearings is En19 or 42CrMO4 which complies with EN10083 and the rolling element, rollers, are made of high chromium steel, which comply with ISO 683-17. The roller elements are separated by spacers which can be individual or they can be segmented. Some of the heavy bearings incorporate the use of continuous cage, which are usually made from bronze. The raceways of Three row roller slew ring bearing are hardened by our in-house induction hardening machine to about 56-58 HRC. Before final assembly takes place, the three row roller bearings undergo stringent checks for axial and radial tilting clearance. Three row roller slew ring bearing is available in the following types: Ungeared three row roller bearing. Externally geared three row roller bearing. Internally geared three row roller bearing. Slew Ring Bearing details: MOC: 42CrMO or C45 MOC of cage: Nylon 6 / Nylon 66 Induction Hardening 55 – 58 HRC High tilting torque Application: Heavy Duty Cranes Wind Mills Crawler Cranes Radars Precision turntables and index tables, Test stands and testing equipment, Robotics, Medical diagnostic equipment, Radar and radio telescope antenna. Crawler crane, marine crane, bucket-wheel excavator, wind turbine, wheeled crane, ladle turret, heavy duty mobile cranes, harbor crane, offshore crane, tunnel boring machine.

FAQ What is a Three Row Roller Slew Ring Bearing? A Three Row Roller Slew Ring Bearing is a heavy-duty bearing with three separate rows of rollers that independently support axial, radial, and tilting moment loads. It is designed for applications requiring maximum load capacity and smooth 360° rotation. Why is a Three Row Roller Slew Ring Bearing used? It is used to handle extremely heavy loads, improve stability, reduce stress on rolling elements, and provide reliable rotational performance in demanding industrial applications. Where is a Three Row Roller Slew Ring Bearing used? These bearings are widely used in heavy-duty cranes, crawler cranes, harbor cranes, wind turbines, bucket-wheel excavators, tunnel boring machines, marine cranes, radar systems, robotics, and large industrial turntables. How does a Three Row Roller Slew Ring Bearing work? It uses three independent rows of rollers to separately carry axial, radial, and moment loads. This optimized load distribution reduces stress, increases rigidity, and ensures smooth, precise rotation under heavy loads. Which industries use Three Row Roller Slew Ring Bearings? Construction, mining, renewable energy, marine, port handling, steel, heavy engineering, defense, material handling, and industrial automation industries commonly use these bearings. How do you choose the right Three Row Roller Slew Ring Bearing? Choose the bearing based on load capacity, bearing diameter, gear type (internal, external, or ungeared), mounting dimensions, rotational speed, operating conditions, and application requirements. What maintenance is required for a Three Row Roller Slew Ring Bearing? Regular lubrication, bolt torque checks, seal inspection, gear inspection, cleaning, and periodic wear monitoring help maximize bearing performance, reduce downtime, and extend service life.
