With a growing presence in European and North American markets, popular linear guide manufacturer, SBC Korea, is at the forefront of technology in high quality linear motion components. We represent SBC exclusively in the UK and other specific markets and the SBC range provides a perfect compliment to the Jena Tec high quality ballscrew range helping us to provide customers with a real "one stop shop" for linear motion.
 
As you would expect the SBC ranges are compatible with many existing manufacturers so a direct drop in replacement rail and guide system is normally available for all major manufacturers.
 
Normal, High and Ultra precision grades are available with defined pre-load levels. Maintenance free options, corrosion resistant units and high load SBI type linear rails mean SBC has everything a mechanical designer needs for a high quality linear system.
 
With many sizes in stock and able to be cut to length within the same working day and shipped overnight, Jena Tec offers unrivalled service for the SBC range. Take a look at our website, for a brief glimpse of the SBC range or call our UK office for further technical support on the number below.

Jena Tec C Type Linear Guides Provide Better Rolling Performance
 
Jena Tec's the SBG(S) - C type linear guides adopt existing 4 row circular arc internal geometry and can therefore interchange with any carriage now operating on SBC standard rail profile. The C type design incorporates ball return tubes and reversing end plates now moulded together as a single component.  MF Block
 
This offers smoother operation than all previous internal designs for linear bearing motion in any plane whether vertical or horizontal. The C type single component mould achieves great reduction in ball direction reversing and "no-load return tube" noise, allowing better lubricant flow . Lubrication is simpler, as the grease nipple can be inserted in multiple orientations ( Front, Left and Right ).

 
 
 
 
Jena Tec MF option linear guides keep going and going........... 

Expensive lubrication systems become a thing of the past and for machines without lubrication, Jena Tec's SBC MF series linear rail option extends the life and performance of your linear system by a significant factor.WBSVH B&T VTL Grinding Spindle
 
  The MF Lubricating Seal now offers longer life for SBC Linear Rail Systems, eliminating the necessity for periodical greasing. The MF Unit contains high quality ,grease filled  fiber seals which will guarantee total surface lubrication and long maintenance free bearing life. The polymer housing containing the surface contact seals are tolerance matched to the guide rail to ensure perfect sealing and smooth motion.
  MF End Cap
MF Seal Units are grease filled and the lubricant  is contained , spread and absorbed by the fiber seals. Using grease rather than oil ensures that the lubricant is retained within the MF seal units  for a much longer working life than oil would remain. The grease used would be compatible with most standard industrial grades recommended for use in bearing blocks and provides excellent thermal stability and water proofing characteristics.

 
 
 
 
 
Tests conducted by SBC show a clear advantage of MF type seals, despite a modest increase in overall length through the slim line design of the fiber seal housing. Results show that for a standard theoretical distance life time calculation of a heavy pre-loaded guide block that the distance for an MF type under heavy load can be increased by 40% up to a 1000Km with no sign of degradation or wear affecting performance or accuracy. For light pre-loads the life extension can be up to a factor of 10 times. Even then replenishment with new MF end caps is a very simple straightforward procedure to give a further period of un-interrupted service.
