Rotary Unions Catalogue WE WILL HOLD, WHT YOU PROMISE
Rotary Unions Introduction The name OTT has been standing for high technology for more than 13 years. Meeting the customer s requirements is our daily work. We are the right contact partner for you in the clamping sector. OTT stands for the state-of-the-art products. Our product s flexibility and adaptability are the basis for satisfied customers throughout world. OTT-JKOB s products are exported worldwide. The implementation of our drawbars provides the evidence of good quality. Contents OTT-JKOB s purpose has been to design rotary unions which perfectly harmonize with a power drawbar. The result is the type 1K-GD. The special feature of these rotary unions is the permanently closed sealing surface. The standard performance parameters are 36.000 RPM at bar coolant pressure and longest life expectancy caused by specially sealed and labyrinth-protected hybrid bearings. The required me dia purity is only <0 μm! dditionally we offer sev eral special GD rotary union types, like for example for high speed up to 7.000 RPM, for higher coolant pres sure, for special dry operations during rotation or higher flow volume. The rotary unions type GD are also suited for operations with an externally mixed erosol (MQS minimum volume lubrication). ll OTT-JKOB rotary unions are balanced and tested after the assembly. The closed sealing surface is unique on the market and proved in thou sands of rotary unions supplied. Due to these features, the volume of leakage is only small, the temperature is low and the life span of the sealing is well longer than the life span of the hybrid bearings. This is very important if the power drawbar is assembled in a very sensitive motor spindle. Rotary Unions Owing to the modularity of the OTT-Jakob rotary unions, it is possible to assemble them in all OTT-JKOB power drawbars with unclamp units connected. Constant interaction with our customers and our continuing development on customer demand has led to a far-reaching experience and a huge number of special rotary unions for the various operations. The following pages will show only a part of our product range, as well give you a short overview of our special-featured rotary unions, for example rotary unions with condition monitoring, temperature monitoring or wear monitor ing. Please contact us and tell us your field of opera tion, we are going to help you finding the right solu tions. Service & repair rotary union is a high-tech component. The OTT- JKOB service department offers the possibility to repair the rotary unions. The members of our service team are specially trained and experienced to suit the quality claims of OTT-JKOB. fter an initial test and inspection of the rotary union you will get a free quotation. ccording to the cause of failure, we are able to create a report for the customer and give advice for better lifetime of the rotary union.

Complete Systems Standardization requires meeting the needs of the user. The Ott universal inside spindle contour is an important step towards modular tooling. It offers the manufacturer of machines and /or spindle units the ability to clamp different steep taper tools (taper/retention knob standard) simply by exchanging the gripper unit. Several variations of power drawbars with or without coolant, with hydraulic or pneumatic unclamp units can be built into the same spindles. Our rotary unions and unclamp units together with our clamping systems and the original OTT-JKOB HSK-clamping units form a unbeatable team. OTT-JKOB HSK clamping units: Trust the original in all it s variations OTT-JKOB rotary unions: 1 and 2 channel rotary unions. We offer the right rotary union for your case of application. OTT-JKOB unclamp units: Hydraulic or pneumatic unclamping. OTT-JKOB Power Check: measuring device used check the force with which the tool is being pulled into the spindle taper. OTT-JKOB Position Controller: The position-controller is a module of the OTT-JKOB position monitoring system.
