Linear bearing type RN

The RN linear bearing represents a consistent optimization of the R linear bearing. Thanks to the enlarged contact surface of the roller with the guideway, the performance capacitiy is significantly increased, with unchanged fitting dimensions. The features of the RN include: – approx. 3x higher load carrying capacity – significantly reduced susceptibility to cage drift – reduced danger of contamination due to narrower gap between individual guides.

Cage assist FORMULA-S from SCHNEEBERGER
 

The cage assist FORMULA-S completely fulfils these requirements in terms of productivity and economic efficiency.It is extremely robust, easy to assemble and consists of only a few components.
FORMULA S is based on the dimensions of our proven RN and RNG ranges. Its clever design means it is easy to incorporate into your existing construction. Above all: FORMULA-S works in any mounting position, regardless of the bearing’s preload.

Advantages

      •   Smooth, trouble-free operation and therefore a more productive period of use High acceleration allows distances to be travelled quickly and therefore reduces cycle times
      •   No readjustments to the cage, not even for vertical installation Geometric tolerances in the surrounding construction or differences in temperature do not lead to instances of cage creeping
      •   Long operating life

Linear bearing type RNG

The RNG linear bearing is a modern, high-performance design and was created through the consistent optimization of the R type bearing. Highly loadable guidance systems with the smallest dimensions can be realized. Through the high performance with comparably small bearing cross-sections, an unrivalled economic efficiency results in many applications.

Linear bearing type R

With the type R, SCHNEEBERGER introduced the first standardized linear bearing in the world. Today it is recognized as an industrial standard. The bearing can be used with rollers or balls and is suitable for many applications with medium to high demands. Combined with SCHNEEBERGER recirculating units, configurations with an unlimited stroke are feasible.

Linear ball bearing type RD​

The RD linear ball bearing complements the R type by providing space-saving solutions. In addition, the use of R and RD linear bearings provides a substantially more economical guidance concept in the user’s construction. Combined with SCHNEEBERGER recirculating units, configurations with an unlimited stroke are feasible.

Linear bearing type N/O
 

The N/O linear bearing has been designed for use with needle cages. These anti-friction guideways are suitable for high-load applications. Together with the closely arranged needle cage the bearing has a very high rigidity. The SCHNEEBERGER plastic and steel composite cage used in these guides gives less resistance to motion than similar needle cages.

Linear bearing type M/V​

Type M/V linear bearings are equipped with needle cages and are suitable for high load applications. The SCHNEEBERGER composite cages used with these guides ensure that there is little resistance to motion as compared to other similar needle bearing guides, while providing very great rigidity.

Sliding Bearings​

In some applications friction-bearings are the better choice compared with frictionless bearings. For such applications SCHNEEBERGER is supplying guideways out of steel, that are equipped with a sliding material specified by the customer.

Lubrication grooves are prepared on request.

Outer dimensions are free and could either be standardized, see linear bearings and customized.

We sell competence and know-how, not standard products!

Remark: In order to quote the correct and comparable product it is absolute necessary to specify the demands for surface quality, grinding pattern, runways, accuracy and application.

Special Bearings

It has to be a frictionless bearing, but the standard dimensions do not fit into your design?

No problem!

You can get any linear guideway! Typical out of through-hardened bearing steel. Single piece rails can be produced up to 6000mm (inductive hardened) resp. 3000mm (through-hardened).

Ball Recirculating Units Type SK

The type SK recirculating unit is equipped with balls and is suitable for low to medium loading. It is used with SCHNEEBERGER type R or RD linear bearings and can be uniformly loaded in every direction. Hence, space saving designs may be realized. Some sizes can be additionally fitted with damping elements (type designation SKD). These provide smoother operation but also have a somewhat reduced load carrying capacity.

Ball recirculating unit type SKC​
 

The recirculating unit type SKC provides unlimited stroke and equal load carrying capacity in all directions. The SKC, designed for low-to-medium loading conditions, operates dry – lubrication is not required! These units, used with SCHNEEBERGER linear bearings type R or RD, are drop-in replacements for SCHNEEBERGER SK and SR recirculating units. The combination of coated stainless steel, ceramic and teflon makes this recirculating unit suitable for lubrication free operation in high vacuum and clean room applications.

Recirculating Unit Type NRT and Preload Wedge Type NRV​

The roller recirculating units NRT are designed for medium to heavy loads, high rigidity and high precision. Together with suitable SCHNEEBERGER linear bearings, adjusting wedge or attaching part ingenious constructions can be realized.

These wedges are used normally to adjust the preload. At the same time, by suitably shaping the cylindrically ground wedge bars, small angular deviations and deformations in the surrounding construction can be compensated. The parts are made from hardened steel.

Standart version
 

The design of the twin race recirculating unit type NRT, is based on a through hardened, highly accurately ground steel careier and two plasic components to recirculate the rollers. On each front face there is a double lipped wiper and a lubricating nipple. There is also an additional lubricating hole in the roller return passage.
