The Braking and Clamping Element with membrane technology KB
The KB series is a hydraulically operated heavy load brake. The hydraulic oil presses the large-surface contact sections, which are equipped with a special brake lining, directly onto the section rail guide via a piston mechanism.
Because of the material combination of the linear guide/contact section, the linear guide won't be damaged by the contact section. In order to prevent damage from chips between the contact section and linear guide, the elements can be fitted with original seals from the respective linear guide manufacturer and longitudinal seals as accessories.
When the braking element is used in harsh work environments or with cooling liquid, seals should be used as well.
A pre-tensioned reset spring enables short cycle times. The special pressure membrane technology guarantees operational reliability. The pressure ranges from 20 bar to a 100 bar maximum for sizes 25 and 30. All sizes from 35 to 125 operate in a pressure range from 30 bar to a 150 bar.
The KB series features zero backlash and extremely low absorption volumes of maximum 7.6 cm3 per clamping operation.
