Oil rotary union SR series

multi-portindustrialhydraulic

Product series
Spherical hydraulic joints that allow hoses to swivel freely on both sides of the joint.

Overview
This design eliminates hose twisting and kinking, which are common causes of hydraulic hose failure. SWIROLLS joints are typically installed on harvester heads or rotating attachments, significantly reducing operational costs by minimizing maintenance, wear and hose replacement.

Applications

• Construction equipment
• Industrial
• Forestry
• Mining
