It's always great to hear of being able to achieve higher load capacities with a similarly sized product and so SBC have done it again in the SBI high load series providing up to 40% increased static and dynamic load bearing cability in a similarly sized cross section with only a minor increase on overall length.
 
If you'd like to hear more about what Jena Tec SBI series linear rail can do for you, then contact Jena Tec on +44 (0)1623 726010 or by email at sales@jena-tec.co.uk

Jena Tec SBI High Performance Linear Rails Improve Loading Capacity by up to 40%!!
 

The SBI range available from Jena Tec provides multiple benefits compared to those offered by the competition in relation to low noise, high rigidity and load coupled with a smooth movement and self adjusting mechanism. Increased load carrying capacities of 40% can be achieved compared to standard block and rail systems.

Compared to conventional linear rail cross sections, the SBI range is approximately 10% lower in height with a wider through section of nearly 20%. Its improved lower cross sectional centre point offers greater structural rigidity, improved straightness during manufacturing and therefore a higher level of straightness in application which benefits the customer for smooth running. Heat treated to HRC60 the SBI range is extremely stable, shorter cross sectional areas mean grinding time and plastic deformation are reduced also.

Similarly, linear blocks are constructed from a hardened steel rigid structure with the same lower cross section centre as the rail and slightly longer block length meaning a greater number of balls are used providing a smooth circular angular motion. This improved track profile and angle results in a smoother and quieter operation.

 
 
 

Standard across the range of SBC products is the heat and chemical resistant end plate with moulded return systems and a self aligning retainer designed to ensure the end plate is correctly fitted in line with the main steel block. Despite an increased load carrying capability the additional length attributable to the SBI range is approximately only 3-4 mm longer than the standard types dependant on carriage model made possible by an improved end plate design. When considering the advantage of 40% increase on load, the additional length is very modest.

Upper and bottom retainer plates fitted to each block ensure that loose steel balls are eliminated as well as skidding and poor rolling performance within the load zone. Additionally, this benefits the cleanliness of the block by preventing ingress of foreign substances. Advocating a simple design philosophy, the SBI retainers are snap assembled and self aligning. The moulded return plate contributes to the smooth running operation of the SBC range as well as keeping running noise low.

 

What about the high load performance? Shown here are some examples of load bearing increased capacity for the SBI range compared to conventional blocks. In some cases up to 40% increases of static and dynamic load capacity can be achieved.

The SBI range achieves this through an improved contact angle of 52% versus the industry standard of 53%. The lower radius of curvature provide a broader contact surface compared to the relevant ball size possible and therefore improves the rigidity.

The improved angular ball re-circulation system with 4 row 2 point contact and 45 degree angular orientation ensure that excellent rolling performance is maintained with low noise even at all grades of pre-load.
