SCHNEEBERGER cross-roller guideways of types R, RN and RNG – we guarantee the right solution

Type R cross-roller guideways
SCHNEEBERGER introduced the R linear guideway/cross-roller guideway and ball guideway as the first standardized frictionless guideways in the world.

Our type R, RN and RNG guideways are available in three quality classes (NQ, SQ and SSQ) for use under operating temperatures of -40° to +80°C. It is also possible to equip RN and RNG guideways with the FORMULA-S cage control to prevent cage creep. Similarly, it is possible to combine R and RD guideways with Type SK, SKD, SKC and SRrecirculating units.

Sizes:1, 2, 3, 6, 9, 12
Special sizes 15 to 24 are produced on request.

Lengths: 20 to 1500 mm

Accessories:

• AC, AK, EE, AA-RF cages
• SR, SK, SKC, SKD recirculating units
• GA, GB, GC, GC-A end pieces
• GD special fastening screws

Type RN
The RN linear guideway / cross-roller guideway is the advanced development version of the R linear guideway. Efficiency is greatly increased without the need for larger installed dimensions thanks to the larger contact surface between rollers and guideway. This guideway features three times more load capacity, high rigidity and precision, as well as the reduced contamination risk due to the narrow gap between the guide rails.

Sizes: 3, 4, 6, 9, 12

Lengths: 50 to 1500 mm

Accessories:

• KBN, KBS cage
• GA and GAN end screws
• GD special fastening screws
• FORMULA-S cage controls

Type RNG
Like the type RN, the linear guideway type RNG has larger contact surfaces for the guideway track. Compared to the R and RN guideways their cross-section is smaller, requiring minimal space and weight-optimization, which offers a decisive advantage in highly dynamic applications.

Sizes: 4, 6, 9, 12

Lengths: 50 to 1500 mm

Accessories

• KBN, KBS cage
• GBN, GCN, GCN-A end pieces
• GDN special fastening screws
• FORMULA-S cage control

The SCHNEEBERGER FORMULA-S cage control
The robust, simple design of the FORMULA-S cage control, consists of only a few components and meets all requirements in terms of productivity and cost-effectiveness. The sophisticated design means it can be easily integrated into existing constructions. FORMULA-S works in any installation orientation regardless of the preload of the guideway.

Advantages
The advantages of cage control include trouble-free operation, high acceleration, and no readjustment of the cage. Furthermore, the shape and position tolerances of the surrounding structure or temperature differences do not lead to cage creep. All in all, an excellent basis for a long service life.
