Pro Level 2Pc 30mm Bore Linear Bushing Featuring Hella Smooth Double Rubber Seal And Round Flange Design For CNC And 3D Printer Projects 45mm Outer Diameter 64mm Length 7mm Mounting Hole Heavy Duty Steel Construction

Smooth double sealed linear bushings for cnc projects
✔️ 30/1in bore, 45/2in OD, 64/2.5in L, 7mm hole steel slides

You get two heavy duty steel slide bushings designed for smooth travel on round shafts. These self sealing units handle steady loads while keeping dust out of your mechanical motion setups.

✅ Body clearance sits at 30mm / 1.18 inch width for shafts
✅ Casing extends 45mm / 1.77 inch outward from center track
✅ Total stretch hits 64mm / 2.52 inch length across frame gaps
✅ Base flange covers 74mm / 2.91 inch surface area for mounts
✅ Bolt apertures measure exactly 7mm / 0.28 inch across holes
✅ Dynamic push strength reaches 160 newtons under motion stress
✅ Static holding power tops 280 newtons when resting firmly
✅ Core metal grades deliver hardness ratings above typical steel
✅ Dual rubber lips block grit while locking lubricant inside

💡 How do sealed linear bearings reduce friction in cnc guides?

The design relies on precise ball tracks and robust shield rings to keep movement slick under pressure.

- Internal rollers glide along hardened grooves to minimize sliding resistance.

- Double seals trap factory grease while shutting out workshop debris.

- Ground steel housings maintain tight tolerances when bolted to flat tables.
