Material
ZX-100K

Description of the application
The cutters are fi xed onto the shaft with rubber laces. The shredded material is leaded from a side to the other one through the shredder shafts (depending on version, one up to four shafts). On the shaft’s side there are the cutters that provide to protect the bearing from very small particles. Once a minute the cutters go up and down the wavelength for 1.500 mm.

Problem
Due to the shredded material, the cutters are expose to abrasive wear and they should not have any gap to the shaft. Also screws, staples and nails should not damage the cutters. The sealing of the bearings against dirt ingress must be permanently guaranteed.

Problem-solving
An axially fi xed split bushing made of ZX-100K is used.

Advantages
The wipers do not need to be adjusted.
