VLA Series L shape

This is a specialized slewing bearing design featuring an external gear on the outer ring combined with an inner flange on the inner ring. This configuration is engineered for applications where compact mounting, easy assembly, and direct drive integration are essential. The flange mounting arrangement provides a practical solution for equipment with limited installation space, while the external gear enables efficient power transmission through direct pinion engagement.


Application Areas：

Compact crane turntables and winch drives

Aerial work platforms and lifting equipment

Solar tracking systems with space constraints

Light to medium-duty industrial turntables

Packaging and handling equipment

Medical equipment requiring compact rotary stages

The VLA series bearing consists of an inner ring with an integral flange, an outer ring with external gear teeth, and a single row of steel balls with spacers arranged between precision-ground raceways. The four-point contact ball geometry allows the bearing to simultaneously support axial loads in both directions, radial loads, and tilting moments within a compact, single-row configuration.

The inner flange serves as a mounting surface that simplifies attachment to the machine structure, eliminating the need for additional adaptor plates or complex fixturing. The outer ring features external gear teeth machined directly onto its circumference, enabling direct engagement with a drive pinion without requiring separate gear components. Both the flange and the outer ring are provided with mounting holes for straightforward bolted installation.
