Slewing Ring Bearings
Slewing ring bearings, also known as turntable bearings, are a type of ball or roller bearing are large bearings which allow for rotation between different components in large structural systems. Ritbearing is a premium supplier of both standard and custom slewing ring bearings and can provide your business with quality parts that match your design needs.
Slewing ring bearings offers several benefits for many different applications. Slewing ring bearings are often selected for their static load capacity. The special geometry of these parts allow them to withstand axial and radial static loads and even tilting moments. These capabilities make slewing ring bearings a natural match for heavy-duty applications with demanding load-carrying needs.
Turntable bearings can also be manufactured with holes to allow for easy mounting directly to a seating surface. This ability offers additional versatility in scenarios where precise positioning is necessary without sacrificing on other key factors.
