Advantages of the hollow shaft slip rings
If the hollow shaft slip rings are to be installed on hot steam lines, an additional sleeve made of heat-insulating material is recommended. Hollow shaft slip rings are maintenance-free and have a precisely defined service life. As they are very inexpensive and easy to replace, their use ensures long-term operational reliability. In summary, hollow shaft slip rings offer the following advantages:
Impact-resistant housing, also made of metal on request
Maintenance-free and durable
Acid- and corrosion-resistant outer material
Reliable transmission of all power and control currents up to 690V
Slip rings are moving components. As a result, they are exposed to high mechanical loads. Even the smaller plastic housings are sufficiently impact-resistant against normal loads. In the metallic version, the hollow shaft slip rings can also withstand powerful lateral impacts. The slip rings can also be used in critical environments, for example in the vicinity of chemical or cooling lines. The transmission reliability of the currents is always guaranteed even at maximum temperature and highest speed. Our hollow-shaft slip rings are also sufficiently radio-interference suppressed so that they do not emit any interfering signals in the vicinity of transmitting and receiving equipment.







Q1: What technical data should be provided for our customized slip ring model.
A: If you want to customize the special slip ring model, you need provide details as below:
1.operating speed(RPM)
2.the type of installation
3.Installation size
4.channels(the No. of single wire besides cable)
5.rated voltage & current for power rings and signal rings
6.the signal type and related
parameters(very important)
7.operating temperature h.IP(sealing requirements)
Q2: How long is your production lead time?
A: It needs 7 to 15 days for standard products, 10 to 20 days for simple customized products,
15 to 40 days for complex customized products.
Q3: What's your delivery port?
A: Our delivery port is Jiujiang, China Mainland
Q4: How do you delivery our goods?
