Details
Through Fixing Type Long Stud Type Bearings The Twin Bearing type which is the default choice, comprises two individual deep groove ball bearings on a single stud. This construction offers compliance allowing smoother running, easy adjustment and greater tolerance of misalignment.
The Double Row Bearing type (DR) incorporates a one-piece bearing with two ball tracks. This offers higher load capacity, especially in the radial direction and is less susceptible to entrapment of debris.
Both types of bearing have been designed specially for Slide system applications and their performance confirmed by rigorous testing. External dimensions are identical.
The Nitrile Sealed option (NS) available for both bearing formats, provides a higher degree of sealing against ingress of water or debris than does the default metal shielded type. A small increase in friction may result.

The Through Hole Fixing type is available in two stud lengths covering most thicknesses of carriage or mounting plate, the short stud version being compatible with the carriage plates. Both versions are available in Concentric type (C) Full items in this series: SJ13,SJ18,SJ25,SJ34,SJ54,LJ13,LJ18,LJ25,LJ34,LJ54,BHJ13,BHJ18,BHJ25,BHJ34,BHJ54
