F-53125.02.NUKR Heidelberg Printing Machine Cam Follower Roller Bearing 16x35x39mm

F-53125.02.NUKR is a NUKR type integrated combined needle roller bearing, integrating radial needle roller assembly and axial thrust retaining washer as one unit. This bearing structure can bear radial load and bidirectional axial load simultaneously, specially designed for cam drive, swing arm and reciprocating transmission positions of printing, packaging and automation machinery.

The outer rolling surface is precision ground thick wall outer ring, matched dense cylindrical needle rollers and stamped steel retainer, with integrated thrust washers on both sides to limit axial displacement. All rolling components and washers adopt fully quenched GCr15 bearing steel, ultra-smooth superfinished contact surface, low friction and stable precision during high-speed reciprocating swing operation. Compact integrated structure saves equipment internal installation space, eliminates the need for separate installation of thrust washers, simplifies assembly procedures. Widely matched printing press cam roller, packaging machine swing arm, textile equipment reciprocating transmission and light automation linear swing mechanisms.

Complete printing machine cam installation drawings, load matching selection guide and long-cycle reciprocating swing durability test reports can be provided upon customer request.

• NUKR integrated composite structure, realizes radial support and bidirectional axial limit at the same time, two-way thrust washers effectively prevent axial sliding of cam roller during high-speed reciprocating swing.
• Thickened outer ring rolling surface with high structural rigidity, strong wear resistance under long-term repeated cam impact load, effectively avoid outer ring surface indentation and peeling.
• Dense evenly distributed needle rollers realize line contact stress dispersion, stable radial load bearing capacity, low vibration and low noise during continuous high-frequency reciprocating movement.
• Precision stamped steel retainer firmly locks needle rollers, prevent needle deviation and shedding under frequent forward and reverse swing alternating load.
• Overall quenching heat treatment reaches HRC60-65 high hardness, excellent anti-fatigue performance, greatly extend overhaul cycle of printing and packaging automation equipment.
• All-in-one integrated forming design, direct press-fit installation on transmission shaft without additional positioning parts, improve production assembly efficiency and reduce spare part inventory types.
• Standard unified installation dimension, fully interchangeable with global NUKR series combined cam roller bearings, no modification to existing cam seat and shaft during aftermarket replacement.
• Comprehensive customized service: P4/P5 high precision upgrade, OEM laser marking on outer ring surface, neutral export carton anti-rust packaging, high temperature anti-wear lithium grease pre-filling.
