K.Line is the exclusive dealers of STAF and TBI linear guides.

Linear guides and blocks are perfectly interchangeable within different precision classes and preloads, allowing customers to easily rationalize their warehouse.

Both sides of the rails can be used as reference and fixed on the machine shoulder; all rails are ground along the full length.

Key Features:

  • High load capacity and torques in all directions
  • Low noise and excellent rolling
  • Long re-lubrication intervals
  • Limitless interchangeability
  • High stiffness of the system
  • Screwing the blocks from the top and from the bottom (flanged types)
  • Rails with nickel coating protection available
  • Blocks with integrated double lip seals for a complete protection
  • Extra-long blocks available (exclusive)

K.Line produces Linear Modules that made linear motion systems very simple and saving costs.

Linear Modules are made of an extruded anodized aluminum guide, where two hardened and chromed shafts are being fixed on; concentric and eccentric wheels run on such shafts and they are integrated with the carriage. The linear units are particularly suitable when accurate positioning and high speeds are required in harsh and dusty environments.

K.Line also produces Linear Slides and Linear Tables, providing excellent positioning accuracy and high rigidity.

The sliding system is made of a carriage with ball bearings on hardened and chromed shafts, or alternatively a recirculating balls block on a liner guide can be used; the carriage is moved by a rolled (usually T7) ball screw.

K.Line is one of the exclusive dealer of TBI ball screws, very well know and established in the linear motion market thanks to their high reliability and precision, combined with long life and maximum performance.

All TBI ball screws components are designed and manufactured taking into consideration the highest market standards.

K.Line is able to provide end machined ball screws with assembled nuts, relying on vast experience and skills of its qualified personnel; preload is also made internally.

Thanks to TRM partnership, K. Line distributes a complete and wide range of bearings with its own EMMEVB brand and ROLLWAY.

The product is used in numerous applications and, thanks to its interesting quality/price ratio, it's greatly appreciated and consequently widely distributed in Italy and Europe.
