⚙️Product Description:
The SKFL004 (20x90x55mm, 20mm shaft bore) is an ultra-lightweight, compact 2-bolt oval flanged housing unit combining a precision-molded zinc-aluminum alloy housing with a high-grade 304 stainless steel insert ball bearing (insert model SUC004 / SUC204 derivative). Designed with a 20mm inner bore, 90mm overall housing length, and 55mm hole-to-hole height, it features a self-aligning spherical insert ball that automatically compensates for mounting misalignments. The combination of a rust-proof zinc alloy housing and a 304 stainless steel ball insert provides superior resistance against moisture, salt spray, and mild chemical washdowns without adding structural weight. Equipped with dual grub screws (set screws) for rigid shaft locking, we supply these lightweight flanged units under our proprietary RMO brand while facilitating flexible multi-brand OEM direct sourcing for food processing, medical automation, and packaging machine manufacturers.
⚙️Product Features:
- 304 Stainless Steel Insert Ball Core: Premium 304 stainless steel inner/outer rings and balls resist oxidation, fresh/saltwater corrosion, and rust under wet conditions.
- Corrosion-Proof Zinc Alloy Housing: Precision die-cast zinc-aluminum alloy body offers smooth surface finish, high strength-to-weight ratio, and complete immunity to rust.
- Automatic Spherical Self-Alignment: Spherical outer interface between bearing insert and housing automatically accommodates angular shaft misalignments.
- Dual Grub Screw Shaft Locking: Eccentric/grub set screw mechanism securely clamps onto 20mm shafts, preventing slip under bidirectional vibration.
⚙️Product Applications:
Engineered for lightweight equipment integration, corrosion protection, and zero-rust hygiene requirements, the SKFL004 zinc alloy flange bearing is widely specified in:
- Food & beverage machinery: light food conveyors, bakery dough rollers, beverage labeling drives, and fruit sorting lines.
- Medical & pharmaceutical automation: pill packaging machines, lab liquid dispensers, medical centrifuge drives, and sterile handling arms.
- Packaging & printing equipment: film slitting machines, cartoning machine rollers, code printing conveyors, and paper sorters.
- Light industrial & aquatic gear: seawater aquarium circulation pumps, hydroponic farm drives, and outdoor solar tracking mechanisms.
⚙️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. |
