231 Series inner flange slewing beairng with outer gear teeth

Longwei transmission slewing bearings in the 231 standard series have one row of four contact point ball bearings with spacers in Nylon. These products are comprised of forged rings, which are machined to form a structure with an outer, square section, rigid toothed ring and an inner flanged ring. Longwei transmission slewing bearings in the 231 standard series are supplied pre-greased.

Longwei transmission slewing bearings in the 231 standard series represent a good compromise between performance and rigidity, with only one flanged ring. The real advantage of this construction lies in its easy assembly, whilst the double seal means it can be installed even in outdoor or dusty environments. Longwei transmission 231 series standard slewing rings can also rotate at 30rpm under low loads.

* food machinery;
* welding tables;
* process automation industry;
* packaging industry;
* lightweight cranes;
