Roller circulation guides form a bearing system for linear movements with unlimited travel length. Due to their versatile arrangement options, roller circulation guides are suitable for numerous applications in general mechanical engineering, especially for linear guides in machine tools when high guiding and positioning accuracy over long travel distances are required.

Roller circulation guides (RUS) consist of:

• INA roller circulation guides with cylindrical rollers as rolling elements
• HYDREL guide rails with up to four raceways for the circulating shoes

Roller circulation guides:

• have very high load capacity
• can be preloaded using adjustment wedges
• are preloaded and extremely rigid
• offer high precision
• have low, consistent friction
• etc.

They are identified under the following designations:

• RUS
• PR
• RUSW

The rails are designated as:

• UG
• UGN
• UGS
• UGSN
• ZU
• UZN
• UZS
• UZSN
• UV
• UFA
• UFB
• UFK

The adapters are designated as:

• APUV
• AUV
• AUVL
• AV
• AVL
