What is lifetime of the parts?

Correctly installed sprung cores (following our catalogue installation instructions) can produce more than 1 million parts.

What is the maximum working temperature of the sprung cores?

The maximum working temperature is 150°C (302°F).

What properties provide Balinit C?

Balinit C is the best coating to apply into our Sprung Cores. It provides a high superficial hardness and a low friction coefficient, i.e., it protects the part and makes it slide smoothly.

What is the minimum opening dimension?

The opening of the sprung cores is a radial movement. Due to this, at the edge of the stroke, the opening is 2.8mm (0.110”). Here you can see a more detailed technical explanation.

Are the Tulip Ejector bushings interchangeable?

Every Ejector is adjusted individually with its bushing, with a tolerance g6/H7 between them. For this reason, it is important to keep track of both pieces in pairs while handling and installing.

Are there any important application details?

Yes, it is very important to give draft on the undercut, for the EE => 5º.
The shaft has to be keyed.
The radius of 0.10mm (0.004”), as minimum, has to be kept if the upper surface of the bushing is grinded or machined.

What is the maximum internal ejector that can be applied?

EE060175: It’s not possible.EE082175: 2mm (0.079”) diameter pin.EE103175: 3mm (0.118”) diameter pin.EE124175: 4mm (0.157”) diameter pin.EE168175: 8mm (0.315”) diameter pin.

It is possible to use the ED or EE without the bushing?

Yes, it is possible under the customer responsability. It is very important to assure the housing dimensions according to the ED or EE dimensions.
