GQZ NUKR90 Concentric Stud Type Track Roller Bearing 90mm OD Double Row Full Complement Cylindrical Roller

NUKR90 is metric concentric bolt-type track roller bearing (cam follower).

• NUKR: Concentric stud design, without eccentric collar; eccentric version marked NUKRE90
• Double row full complement cylindrical rollers, no cage, maximum roller quantity for outstanding radial load capacity
• Thick-walled outer ring, standard crowned outer running surface; flat cylindrical surface optional (suffix X)
• Integral threaded stud M30×1.5, built-in hexagon socket for easy mounting
• Both-side labyrinth seals, equipped with re-lubriion channel on stud

Designed to roll directly on guide rails, cam surfaces. It withstands heavy radial loads and tolerates moderate axial loads caused by deflection or misalignment. Widely used on automated conveyor lines, printing machinery, packaging equipment, textile machinery, heavy cam transmission and low-medium speed linear motion systems.
