Six-row linear recirculating ball bearing and guideway assemblies
Features
 

Linear recirculating ball bearing and guideway assemblies KUSE are full complement systems and are preloaded. They are used in applications with long unrestricted strokes, high and very high loads and high to very high rigidity.

 
 

A guidance system comprises at least one carriage with a full complement ball system, a guideway and plastic closing plugs.

 
 

The units can be ordered separately as carriage KWSE and guideway TKSD or as a unit KUSE. In a unit, one or more carriages are mounted on a guideway.

 
   

Load carrying capacity

 

The linear recirculating ball bearing and guideway assemblies have six rows of balls. The four outer rows have a contact angle
See
Operating contact angle
Nominal contact angle
of 45° and the two inner rows have a contact angle
See
Operating contact angle
Nominal contact angle
of 60° to the raceways, Figure 1.

 
 

Four rows of balls support compressive loads while two rows of balls support tensile loads and all six rows support lateral loads.

 
 

The units can support loads from all directions – except for the direction of travel – and moments about all axes, Figure 1.

Carriages

 

The carriages have saddle plates made from hardened steel and the rolling element raceways are precision ground. The balls are recirculated in enclosed channels with plastic return elements.

Guideways

raceways are precision ground.

 
   

Located from above or below

 

Guideways TKSD (-ADB, -ADB+K) are located from above, guideways TKSD..-U are located from below. All through holes have counterbores for the fixing screws or threaded blind holes.

 
   

Slot for covering strip

 

Guideways TKSD..-ADB have a slot for the adhesive bonded steel covering strip (ADB) and guideways TKSD..-ADB+K have a slot with undercut for a clip fit steel covering strip (ADB+K).

 
   

Multi-piece guideways

 

If the required guideway length lmax is greater than the value in the dimension tables, the guideways are supplied in several pieces, see link.

Operating temperature

 

KUSE units can be used at operating temperatures from –10 °C to +100 °C.

Carriages are always pushed directly from the guideway onto the dummy guideway and must remain there until they are reassembled.

 
   

Plastic closing plugs

 

The plugs close off the counterbores of the guideway holes flush with the surface of the guideway.

 
 

Optionally, brass closing plugs are also available, see link.

 
   

Corrosion-resistant designs

 

Six-row linear recirculating ball bearing and guideway assemblies KUSE are also available in corrosion-resistant designs with the special coatings Corrotect®, Protect A and Protect B.
