⚙️Product Description:
The 305803C-2Z (17x47x17.5mm) is a heavy-duty, double-row angular contact track roller bearing (cam follower) engineered specifically to run directly on flat, curved, or profiled guide tracks. Featuring a 17mm inner bore, 47mm outer diameter, and 17.5mm total width, it is built with an extra-thick outer ring designed to withstand high radial impact loads and heavy contact stresses without structural ring deformation. Equipped with internal double-row angular contact ball geometry and dual steel dust shields (2Z), this unit delivers smooth guidance, high tilting moment resistance, and exceptional running accuracy. We supply these high-performance track rollers under our proprietary RMO brand, supported by global multi-brand OEM direct sourcing for automated machinery, material handling systems, and printing equipment manufacturers.
⚙️Product Features:
- Heavy-Duty Thickened Outer Ring: Specially reinforced outer ring resists high repetitive shock loads, track contact stresses, and edge crushing during continuous rail rolling.
- Double-Row Angular Contact Internal Geometry: High-rigidity internal layout accepts substantial combined radial forces, bi-directional thrust loads, and severe tilting moments.
- Optimized Running Surface Profile: Precisely ground outer cylindrical (or crowned) face ensures uniform pressure distribution along guide rails, preventing premature track wear.
- Dual Steel Shields (2Z) & Pre-Greased: Double metal dust shields safeguard internal raceways against metal debris and industrial grit while retaining factory synthetic grease.
⚙️Product Application:
Engineered for track guidance, high impact resistance, and heavy radial line contact, the 305803C-2Z track roller bearing is widely specified in:
- Conveyor & material handling: automated overhead conveyors, sorting line guide tracks, and pallet transfer cams.
- Printing & packaging machinery: offset press gripper cams, die-cutting guide rollers, and cartoning machine drive tracks.
- Industrial automation: linear gantry guide systems, rotary indexing cams, and automated assembly transfer stages.
- Textile & woodworking equipment: heavy loom cam drives, sliding panel saw guides, and veneer lathe tracking rollers.
⚙️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. |
