Product Description

1. Product Overview

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-lubrication 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.

Formal quotation will be sent within 24 hours upon your inquiry.
