⚙️Product Description:
The NUKR47 / NUKR47/A (20x47x66mm, M20x1.5 thread) is a heavy-duty stud-type track roller (cam follower) engineered with a full complement double-row cylindrical roller assembly. Featuring a 20mm stud shank diameter, 47mm outer roller diameter, and 66mm overall length, this rigid unit replaces a standard inner ring with a solid, high-strength threaded stud. Designed with a thick-walled outer ring and integral axial guidance, it is built to sustain extremely high dynamic radial shock loads and dynamic tilting moments without roller tilt or housing deformation. Available in standard cylindrical outer ring or crowned outer ring (NUKR47/A) options, we supply these heavy-duty cam followers under our proprietary RMO brand while facilitating flexible multi-brand OEM direct sourcing for global automation machinery and heavy material handling manufacturers.
⚙️Product Features:
- Full Complement Cylindrical Roller Design: Maximize roller line contact density within the raceway to handle massive dynamic and static load capacities under continuous heavy rolling.
- Integral High-Strength Threaded Stud (M20x1.5): Solid cold-forged steel stud with integral mounting thread allows fast, rigid direct cantilever installation onto machine frames.
- Thick-Walled Outer Ring & Axial Flange Guidance: Heavy-section outer ring withstands severe edge pressures, while integral side flanges guide rollers under heavy lateral thrust.
- Labyrinth Seals & Relubrication Duct: Multi-stage labyrinth seals protect raceways from metal chips and dust, while internal grease ducts on the stud allow easy field maintenance.
⚙️Product Application:
Engineered for heavy cantilever mounting, high shock absorption, and high-load track guidance, the NUKR47 stud type track roller is widely specified in:
- Automation & material handling: automated transfer gantries, heavy palletizer indexing arms, and sorting system guide tracks.
- Metal forming & presses: stamping press slide mechanisms, sheet metal shears, and automated die lifters.
- Packaging & indexing machinery: continuous rotary indexing cams, bottle labeling drive tracks, and cartoning machine linkages.
- Heavy industrial machinery: foundry mold transfer cars, CNC machine tool slide ways, and textile loom cam drives.
⚙️Precautions:
| 1. Keep clean | 2. Use with caution | 3. appropriate tool | 4. Hot-loading | 5. Be careful of rust |
| Dust will have a bad effect on the bearing, so keep the surrounding clean. | Strong impact during use can easily cause scratches and indentations. | Avoid replacing existing tools, and use appropriate tools. | Bearings are precision parts, so hot installation is recommended. | Sweat on your hands during operation will cause rust, so it is best to wear gloves. |
