Linear Guides - Chieftek Precision (Ball Bearing Type)


Chieftek Linear guide blocks and rail assemblies provide high capacity, low friction guidance of payloads.  With 4 rows of recirculating balls engaged in a precision ground rail, these bearings provide load capacity in all directions.

  • Industry standard sizes 15 to 55 are available
  • Load capacities from 17.5 kN to 240 kN (3934 lbs to 54000 lbs)
  • Rail lengths up to 4000 mm (157.5 inches) with splicing available longer lengths

As you go deeper into this section of our website you will find some preconfigured product is available for online ordering.  Most of this product is stocked locally Rails are cut to length at time of order.  This makes it convienient for us to cut a rail to your exact length requirement.  There are a significant number of combinations of rail lengths and block possbilities.  So if you have a particular requirement that could not be found on our website, please call (803) 396-5544 or email us your requirement and we will provide you with price and lead-time to do this.

Miniature Linear Guides

Miniature Linear Guides - Chieftek Precision (Ball Bearing Type)


Miniature Linear Guides provide precision, low friction guidance of payloads for machine and instrument applications.  These bearings have 2 rows of recirculating balls engaged with 4 point contact in a precision ground rail which provides load capacity in all directions.

  • Industry standard sizes 3 to 15 in both standard and wide format rails
  • Load capacities to 12 kN (2800lbs)
  • Rail lengths to 1200 mm
  • Options for seals, scrapers, and maintenance free lubrication
  • Stainless Steel construction and optional Raydent® treatment for corrosion resistance
Rosa Linear Guide Assembly

Linear Guides - ROSA Sistemi (Roller Bearing Type)


Rosa Systemi linear roller bearng type guide block and rail assemblies provide the highest load carrying capacity.  Four rows of recirculating rollers mate with a precision ground rail providing support in all directions.

Best for applications requiring:

  • Very high stiffness and rigidity
  • Extremely smooth movement
  • High load carrying capacity

Industry standard sizes 25 to 55 are available.   Load capacities range from 29 kN TO 351 kN (6500 lbs to 79,000 lbs).  Rail Lengths to 4000 mm with splicing (butt joints) available to make longer lengths

High Temp Bearings

High Temperature Linear Bearings


High Temperature Linear Bearings provide load capacity and precision guidance like standard linear guides but are modified for high temperature environments.  The all metal construction is suitable for temperatures up to 180°C (356°F).  Recirculating ball rails and economical cam rollers based designs are available. 

  • Industry standard sizes 15 to 55
  • Load capacities from 4.5kN to 320kN (1000lbs to 72,000lbs)
  • Rail lengths to 4000mm with splicing available for longer lengths
  • Corrosion resistant options for Raydent®, TDC, and TDNC
