3 Pack Heavy Duty Sleeve Bearings 6Mm X 8Mm X 15Mm Oilless Bushings Built Like A Tank Carbon Steel Bronze Core For Electrical Systems And Auto Mods Hassle Free Maintenance Pro Quality
3 Pack Oilless Sleeve Bearings 6mm Bore 8mm OD 15mm Length
✔️ Carbon steel with sintered bronze core self lubricating 3 pcs bulk pack
This 3-pack of oilless sleeve bearings offers a robust tri-metal build combining a carbon steel shell, sintered bronze backing, and a PTFE-lead lining for dependable sliding action. The copper-plated exterior ensures proper seating in housing bores while the self-lubricating core slashes maintenance needs across the board. Whether you are working on electrical motor shafts, auto racing components, or industrial actuators, these bushings handle moderate speeds and loads without leaking grease.
✅ Model 0615 design with carbon steel shell and sintered bronze insert for heavy load ratings✅ Inner diameter of 6mm matches 0.24 inch shafts while outer diameter sits at 8mm or 0.31 inch for snug fits
✅ Total length measures 15mm plus 0.59 inch allowing ample contact surface area along the bearing axis
✅ Dry friction coefficient ranging from 0.04 to 0.2 ensures slick movement even under moderate pressure conditions
✅ Pack contains three identical oilless bushings ready for immediate installation in workshop builds or production runs
💡 How do tri-metal sleeve bearings handle shock loads and misalignment better than simple cast iron designs?
Taking advantage of layered metallurgy, these oilless bushings make maintenance handy by eliminating lubrication schedules while delivering robust load handling for tough jobs.
- Carbon steel outer jacket provides structural rigidity to resist deformation under heavy radial forces without permanent distortion
- Porous bronze intermediate zone serves as both cushion and reservoir holding residual lubricant against hot running conditions
- Soft metal overlay coating creates an instant conformable seat over shaft irregularities preventing scoring during initial engagement phases
