Track roller guidance systems
Features
Track roller guidance systems are available with a hollow section carriage, compact carriage, open carriage, non-locating bearing carriage or bogie carriage.
Track roller guidance system with bogie carriage
Bogie carriages LFDL..-B and LFDL..-SF can be used in combination with curved guideway elements LFSR..-ST to achieve almost any variant of oval and circular track guidance systems. The straight guideway elements are precisely matched to the arc.
The carriages LFDL..-B and LFDL..-SF comprise a steel carriage plate, two aluminium swivel brackets (supported axially and radially by rolling bearings). In the case of LFDL..-B, the preload of the four profiled track rollers can be set by means of two concentric and two eccentric bolts. In the case of LFDL..-SF, the preload is already preset to the optimum value by means of four concentric bolts, ➤ Figure.
ACHTUNG
LFDL..-SF cannot be mounted on closed curved guideway systems.
Bogie carriage
Sealing and lubrication
The track rollers have gap seals on both sides, are greased for life and are therefore maintenance-free.
The contact zone between the raceways and track rollers must be lubricated via the shaft.
Corrosion-resistant design
All steel parts, the inner and outer rings of the track rollers and the bolts, washers and nuts are made from corrosion-resistant steel. The rolling elements are protected against corrosion by the grease.
Corrosion-resistant designs have the suffix RB (available by agreement only).
ACHTUNG
The adjustable carriage LFDL..-B must be used in combination with a 360° guideway.
