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 compact carriage
The closed compact carriage LFKL..-SF gives a simple means of achieving track roller guidance systems for operation in contaminated environments. The track rollers are protected against contamination by the closed design. It has two integrated lubrication units for lubrication of the raceways.
A carriage comprises a saddle plate made from anodised, profiled aluminium, four concentric bolts, four track rollers, two sealing strips and two lubrication and wiper units, ➤ Figure. The track rollers are already fitted, the sealing strips as well as the lubrication and wiper units are included loose in the delivery.
Compact carriage
Preload and clearance
The carriages run clearance-free on all INA guideways and can be combined with all guideways of the relevant size, but not with the curved guideway elements LFSR. Due to the highly accurate guideways, it is not necessary to set the clearance.
Sealing and lubrication
The track rollers have gap seals on both sides, are greased for life and are therefore maintenance-free.
For lubrication of the raceways, the lubrication and wiper units have oil-soaked felt inserts that can be replenished with oil via lubrication nipples. In combination with the sealing strips (gap seals), these units protect the compact carriage on all sides against contamination.
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.
