Pro Grade Oil Free Sintered Plain Bearings Dri Plane C Bushings 5 16 Bore 3 8 Od 5 8 Length Pack Of 3 Heavy Duty High Heat Resistant Up To 700 F Zero Grease Required Smooth Operation
High Temp Oil-Free Sintered Bushings Pack of 3
✔️ Bore 5/16 OD 3/8 Length 5/8 Metal Sintered 700°F Rated
These oil-free sintered bare bushings provide smooth rotation without grease maintenance. You can install them in heavy machinery shafts or conveyor rollers where dirt exposure risks traditional lubricants. The dense metal construction handles demanding cycles while resisting wear over time.
✅ Zero grease requirement keeps surfaces clean and avoids outgassing in sensitive areas.✅ Handles continuous heat resistance up to 700 degrees Fahrenheit under steady rolling loads.
✅ Matches ASTM specifications for chemical resistance and reliable physical strength in jobsites.
✅ Comes as a set of three units measuring 5/16 inch bore with 3/8 inch OD and 5/8 inch overall length.
💡 What are the main benefits of high temperature dry lubricated plain bushings for rugged applications?
Running sintered metallic rings stops old-school grease from baking hard on hot surfaces so your equipment stays reliable through the summer heat.
- Handy dry-film coatings slide against mating metal parts without dragging torque or grabbing when temperatures spike.
- Skip the drip and mess since there is zero oil to leak out and foul up nearby wiring or control panels.
- Porous shell design traps wear dust inside the ring so you avoid scoring expensive crankshafts from gritty debris.
- Built-in toughness takes punishment from shock loads and misalignment that would crack brittle polymer sleeves.
