• With the excellent pressure balance design, thrust load generated from the internal pressurized fluid is balanced well so that excessive load is not added to the bearing.　They endure extreme pressures and provide stable operation with little rotary torque fluctuations due to pressure.
• Large mechanical strength due to an <O-ring> with special backup ring used in the seal seciton and 2 <radial ball bearings> contained in the bearing section.
• Maintenance is easy, with simple structure and <O-ring> and <backup ring> being the only consumables.

Flange-type joints (SRK-2F and 3F) can also be manufactured upon request. Please inform the flange specifications.
