⚙️Product Description:
The LMF30UU (30 x 45 x 64 mm) is a round flange linear motion ball bearing designed for secure face-mounting and rigid perpendicular guidance along 30mm precision linear shafts. Featuring a 30mm inner shaft diameter, 45mm outer cylinder diameter, and 64mm overall length, this flanged linear bushing incorporates an integrated pilot flange with pre-drilled mounting holes. It eliminates the need for external mounting blocks, providing direct bolt-on installation for heavy load stroke mechanisms. Dual rubber wiper seals (-UU) retain internal grease while excluding dust, swarf, and debris. We supply warehouse stock of our flagship RMO brand alongside global brand procurement to service CNC routers, plastic injection molding machinery, automated gantry systems, and heavy-duty 3D industrial printers.
⚙️Product Features:
- Integrated Round Flange Mounting: Built-in pilot flange allows direct bolt-on assembly against flat housing walls, ensuring perfect perpendicular alignment without extra adapters.
- Smooth Reciprocating Ball Motion: Precision steel ball circuit guides recirculating ball loops within a heat-treated outer sleeve for low-friction, stick-slip-free linear stroke.
- Dual-Lip Wiper Seals (-UU): Dual contact synthetic rubber wiper seals effectively wipe dirt off the 30mm guide shaft while preventing lubricant leakage.
- High Rigid Radial Load Capacity: Engineered for 30mm hardened shafts, providing superior load distribution and resistance to moment forces during rapid axial movement.
- Dual Supply Availability: Direct bulk factory delivery from RMO warehouse inventory combined with quick procurement channels for top international bearing brands.
⚙️Product Application:
- CNC Routers & Woodworking Machines: Multi-axis woodworking CNC gantries, heavy stone engraving spindles, and automated panel saws.
- Plastics & Injection Molding: Core puller guide shafts, mold ejector pin plates, and blow molding machine clamping mechanisms.
- Automated Gantry Systems: Material handling pick-and-place gantries, robotic palletizer slide rails, and automated warehouse lifters.
- Heavy Industrial Printing & Packaging: High-speed cartoning machines, flexographic printer guide rods, and industrial additive manufacturing beds.
⚙️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. |
