2620-040-157 is a reliable dual joint designed specifically for high-speed rotating machine tool components that require two different media channels. Due to the cold operation of the joint, it is highly suitable for machine tool spindles and is recommended for use in plate clamps and rotary cylinders. Special models for variable pitch blower applications can also be provided. The original design of this joint can only use the same medium in two channels and cannot be used for different media, as channel leakage may occur when the seal wears out. We can provide E.L.S. (extended life type) seals for hydraulic systems according to user requirements.
Structural characteristics and advantages
Sealing design: Each channel is equipped with a balanced mechanical seal, which can maintain a closed seal even under maximum pressure, extending its lifespan and reducing torque.
Bearing protection: Equipped with dual precision ball bearings and a labyrinth structure to protect the bearings from medium contamination.
Cold operation characteristics: Adopting a “cold operation” design with low heat generation, it is particularly suitable for temperature sensitive applications such as machine tool spindles, plate clamps, and rotating cylinders.
Product Introduction
Two independent channels, suitable for applications such as clamping and releasing
Balancing mechanical seals in each channel can improve lifespan and reduce torque, even under high pressure
Closed seal provides continuous medium
Double precision ball bearings, smooth operation
Maze structure to protect ball bearings
When using multiple connectors, only one channel should be pressurized at a time. The other channel should have an open discharge outlet to prevent cross channel leakage.
Lubrication method:
1: Gas seal lubrication can be achieved through an oil cup or by using oil and gas
2: Gas seals do not require external lubrication
