Four-row linear recirculating ball bearing and guideway assemblies with integral electronic-magnetic measuring system

Four-row linear recirculating ball bearing and guideway assemblies KUVE with an integral electronic-magnetic measuring system are ready-to-fit units. They comprise a carriage KWVE with a modified housing containing an integral measuring head and guideway TKVD with a longitudinal slot. A SIKO dimensional scale is fixed by adhesive in this slot. The dimensional scale is well protected against dust, contamination and wear by means of a covering strip.The system for absolute digital length measurement (LMSD) is supplied with an electronic evaluation system.In the system for incremental length measurement (LMST), this is already integrated in the measuring head.Since the system is integrated fully in the guidance system, it requires no additional space. As a result, the design of the adjacent construction can be made more compact.The measuring system is used for measuring the travel distance and gives direct measurement of the distance moved by magnetic sensing (either incremental or absolute measurement is possible). It operates without pitch-related or measurement errors.A single-track dimensional scale with a pole pitch of 5 mm is applied to the magnetic strip. The maximum travel speed of the carriage is 5 m/s, the maximum measurement length is 90 m.

The mechanical component of the monorail guidance system corresponds to the established linear ball bearing and guideway assembly KUVE. These units can support forces from all directions and moments about all axes, are preloaded and have high accuracy, rigidity and load carrying capacity.The combination of these proven linear ball bearing and guideway assemblies with the electronic-magnetic measuring system gives a very compact, cost-effective solution for applications that require particularly precise travel distances.

FeaturesFour-row linear recirculating ball bearing and guideway assemblies KUVE with an integral electronic-magnetic measuring system■ are complete units comprising:

– a carriage with a modified measuring head– a guideway suitable for accommodating the magnetic

strip and covering strip■ expand on the advantages of the proven linear

ball bearing and guideway assemblies KUVE without a measuring system by means of:– direct measurement of travel distances

(by incremental or absolute measurement)– considerably reduced installation work– increased accuracy– reduced logistical work

■ can support forces from all directions and moments about all axes

■ are preloaded■ have high accuracy, rigidity and load carrying capacity■ are protected against contamination by

– integral elastic wipers on the end faces of the carriage and sealing strips for sealing the carriage

■ can be lubricated with oil or grease– a lubrication nipple is screwed into the end piece of

the carriage for lubrication of the raceway.

Electronic-magnetic measuring systemThis system:■ is used to measure the travel distance■ measures the distance covered by direct means

– eliminating pitch-related or measurement errors arising from mechanical clearance

■ is completely wear-free and resistant to dust, contamination and vibration

■ is user-friendly■ is cost-effective■ is easy to handle.
