The EBL series is a compact slewing bearing solution combining an external gear on the outer ring with an integrated inner flange on the inner ring. This design is specifically developed for applications requiring a low-profile mounting arrangement without sacrificing the load-handling efficiency of four-point contact ball technology.
Space-constrained crane turntables and winch drives
Aerial work platforms with height limitations
Compact solar tracking systems
Light to medium-duty industrial turntables
Packaging and handling equipment
Medical equipment requiring low-profile rotary stage






The EBL series bearing comprises an inner ring with an integral radial flange, an outer ring with external gear teeth, and a single row of steel balls with nylon spacers arranged between precision-ground raceways. The four-point contact ball geometry enables the bearing to simultaneously support axial loads in both directions, radial loads, and tilting moments within a single, compact row of rolling elements.
What distinguishes the EBL series is its flange geometry: the inner flange is designed with a reduced axial height while maintaining sufficient structural stiffness for most light to medium-duty applications. This low-profile flange design makes the EBL series particularly suitable for applications where vertical space is at a premium. The external gear teeth are cut directly on the outer ring circumference, allowing direct pinion engagement with minimal transmission losses. Both the flange and the outer ring are provided with mounting holes for quick and secure bolted installation.
