⚙️Product Description:
The SRF50 (34.925 x 63.5 x 25.273 mm / 1-3/8″ x 2-1/2″ x 0.995″) is a heavy-duty inch-series yoke-type track roller (yoke-type cam follower) engineered with a precision-caged needle roller complement. Precision-machined from high-grade AISI 420 martensitic stainless steel, this clevis-mounted unit replaces stud-type followers by fitting directly onto a support pin or clevis shaft. Featuring a thick-walled outer ring, integral side flanges, and a rigid needle roller retainer, it absorbs high dynamic radial shock loads while offering high-speed performance, low frictional heat, and outstanding resistance to rust and liquid washdown spray. Supplied under our proprietary RMO brand, we also offer flexible multi-brand OEM direct sourcing for food processing lines, bottling equipment, and marine material handling system builders.
⚙️Product Features:
- 420 Stainless Steel Construction: Martensitic stainless steel rings and caged needle rollers resist rusting, pitting, and chemical attack in harsh washdown environments.
- Clevis-Mounted Yoke Architecture: Designed without an integral stud to mount directly onto support pins, distributing high overhang loads evenly across dual support arms.
- Caged Needle Roller Assembly: Rigid retainer separates and guides needle rollers precisely, reducing internal friction, heat generation, and grease breakdown at higher speeds.
- Thick-Walled Outer Ring & Flange Guidance: Heavy-section outer ring absorbs severe rim crushing stress, while integral side flanges handle lateral axial thrust and alignment loads.
⚙️Product Application:
Engineered for dual-supported pin mounting, high-speed rolling, and severe rust prevention, the SRF50 stainless yoke-type track roller is widely specified in:
- Food & beverage processing: stainless chain conveyor tracks, bottle washing guide rails, and automated packaging sorters.
- Chemical & pharmaceutical lines: liquid filling line cam drives, sterile oven transfer carts, and pill box indexing linkages.
- Marine & offshore handling: deck crane trolley tracks, boat lift guide rollers, and port container spreader linkages.
- Automated assembly lines: automotive paint shop dip line rollers, heavy transfer gantries, and industrial furnace conveyors.
⚙️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. |
