Custom 316 Stainless Steel Bushing CNC Precision Machined Corrosion Resistant Sleeve Fittings
Situo Hardware is a professional CNC manufacturer specializing in corrosion-resistant stainless steel fittings. We focus on producing Custom 316 Stainless Steel Bushing and CNC Precision Machined Corrosion Resistant Stainless Steel Sleeve Fittings for marine equipment, chemical machinery, food medical equipment and industrial automation systems.
Made of authentic 316 solid stainless steel with molybdenum element, our custom bushings feature excellent acid and alkali resistance, salt spray resistance and seawater corrosion resistance, far exceeding ordinary 304 steel and carbon steel sleeves. Integral CNC one-piece machining ensures high roundness, smooth inner wall and precise matching clearance, effectively solving rusting, jamming and rapid wear problems of ordinary mechanical bushings.
Adopting industrial-grade 316 solid stainless steel raw material with molybdenum alloy composition, our bushings provide outstanding anti-corrosion performance in seawater, salt spray, acid-base and humid working environments. The dense and pore-free material structure undergoes professional stress relief treatment, ensuring stable mechanical performance for long-term outdoor and corrosive environment operation.
All 316 stainless steel bushings are completed in one clamping process, finishing inner and outer circle milling, step positioning, chamfering and grooving integrally. The stable tolerance reaches ±0.005mm with high coaxiality and smooth burr-free inner wall. Precise fitting clearance ensures smooth sliding and rotating operation without jamming, noise or shaking.
The solid one-piece cutting structure has no welding seams or hollow defects, providing high rigidity, impact resistance and fatigue resistance. Optimized for high-frequency reciprocating friction and heavy-load vibration working conditions, our 316 stainless steel sleeves maintain stable structural accuracy and wear resistance for a long time.
We provide full non-standard customization of all 316 stainless steel bushing types, including straight sleeves, stepped positioning bushings, flange fixing sleeves, slotted buffer bushings, thin-wall micro sleeves and special-shaped structural parts. Custom inner diameter, outer diameter, length and structure are available according to customer drawings and samples.
All finished 316 stainless steel bushings undergo full-dimensional inspection, salt spray sampling test, surface finishing and simulated assembly testing before delivery. The batch qualified rate exceeds 99%. Optional polishing and passivation treatments further enhance surface durability and anti-rust performance.

Material spectrum reports and full inspection documents can be provided.
A: 316 stainless steel contains molybdenum element, providing stronger seawater resistance, acid and alkali resistance and salt spray corrosion resistance. It is more suitable for marine, chemical and wet corrosive working environments than 304 steel.
A: Yes, we fully customize non-standard inner/outer diameter, length, step, flange and special-shaped structures according to customer drawings and samples.
A: We stably control the tolerance within ±0.005mm with high roundness and smooth inner wall, ensuring precise clearance fit and stable mechanical operation.
A: Yes. 316 stainless steel has high hardness and excellent friction resistance. Combined with precision CNC finishing, it maintains long-term stable wear resistance in continuous sliding and rotating working conditions.
