CXE supplies custom stainless steel sleeve bearings, shaft bushings, flanged sleeves, wear-resistant bushings, and special machined sleeve parts for industrial buyers. Many stainless sleeve bearing orders are not standard catalog items, so buyers can send drawings, samples, photos, dimensions, material requirements, and quantity for RFQ review.
Use this page to review representative stainless sleeve bearing types that CXE can manufacture or quote. The images below show common design directions, including cylindrical sleeves, flanged bushings, oil-groove bushings, heavy equipment sleeve bushings, and special-shaped stainless machined parts.
Custom Stainless Sleeve Bearing Types
Cylindrical sleeve bearings with oil holes, grooves, or sliding surfaces for rotary and linear motion assemblies.
Straight sleeves, stepped sleeves, grooved sleeves, spacer-type bushings, and custom machined bearing sleeves.
Flanged sleeve bearing designs help with axial positioning, mounting location, and stable fit in equipment housings.
Larger sleeve bushings can be quoted for repair, maintenance, and equipment rebuild projects when drawings or samples are available.
Oil grooves, lubrication holes, retaining grooves, chamfers, and stepped shoulders can be reviewed from drawings.
Non-standard shapes, threaded sleeve parts, stepped sleeves, and drawing-based custom stainless components can be quoted.
Send Drawing For Custom Sleeve Bearing Quote
For a faster quotation, send the drawing or sample information together with the required quantity and working environment. If a drawing is not ready, CXE can still review photos and key dimensions first, then confirm missing details before production.
Useful RFQ information:
- Drawing, sample photo, or existing part number
- Bore diameter, outside diameter, length, flange diameter, and flange thickness
- Material requirement such as 304 stainless steel, 316 stainless steel, or other stainless grade
- Oil groove, oil hole, retaining groove, chamfer, thread, or stepped profile details
- Surface finish, hardness, tolerance, and sliding surface requirement if specified
- Quantity, target application, shaft material, load direction, and working environment

What Are Stainless Steel Sleeve Bearings?
A stainless steel sleeve bearing is a cylindrical plain bearing that allows a shaft to rotate or slide inside a supporting sleeve. Unlike ball or roller bearings, sleeve bearings rely on sliding contact, material pairing, lubrication, or self-lubricating design to support motion.
Stainless steel construction is selected when corrosion resistance, washdown resistance, clean appearance, or improved durability is required. Common buying requirements include stainless shaft bushings, stainless plain bearings, flanged sleeve bearings, spacer sleeves, and custom machined bushings.
Common Custom Design Options
Straight Cylindrical Sleeves
Straight sleeve bearings are used where the housing already controls axial location. They are compact, simple, and suitable for many rotary or sliding shaft assemblies.
Flanged Sleeve Bearings
Flanged sleeve bearings include an integral shoulder that helps locate the part axially. This design is useful when mounting stability, positioning, or easier assembly is required.
Oil-Groove And Oil-Hole Bushings
Oil grooves and oil holes help distribute lubricant across the sliding surface. Send the groove position, hole count, hole diameter, and lubrication path if these details are critical.
Stepped And Special-Shaped Sleeves
Stepped sleeves, threaded parts, shouldered bushings, and non-standard stainless components are usually drawing-based. These should be quoted from a technical drawing or a physical sample.
Material Options
- 304 stainless steel: suitable for many clean, humid, and general corrosion-resistant applications.
- 316 stainless steel: selected when higher corrosion resistance is required, especially in marine, chemical, or stronger washdown environments.
- Other stainless grades: can be reviewed when hardness, wear resistance, magnetic behavior, or cost target is important.
- Solid lubricant or composite design: available for some self-lubricating sleeve bearing requirements when external lubrication is limited.
Stainless Sleeve Bearings Vs Bronze Bushings
Bronze bushings are widely used for sliding motion and load support, but stainless steel sleeve bearings may be preferred when the buyer needs corrosion resistance, cleaner appearance, stainless material compatibility, or a specific custom machined stainless part.
The best choice depends on load, shaft speed, lubrication, temperature, mating shaft material, surface finish, and environmental exposure. For custom projects, send the application details so CXE can review the design direction before quotation.
Applications
Stainless steel sleeve bearings and custom bushings can be used in industrial machinery, repair and maintenance projects, automation equipment, packaging machinery, food-related equipment, clean mechanical assemblies, marine-adjacent equipment, guide shafts, rotary shafts, and special OEM assemblies.
Frequently Asked Questions
Can CXE make stainless sleeve bearings from drawings?
Yes. Send the drawing, material requirement, quantity, and working environment. If only a sample or photo is available, send the key dimensions first for initial review.
Can oil grooves and oil holes be customized?
Yes. Oil grooves, oil holes, chamfers, steps, flanges, and retaining grooves can be reviewed when the drawing provides position, size, and tolerance details.
Which stainless material should I choose?
304 stainless steel is suitable for many clean and humid environments. 316 stainless steel is preferred when corrosion resistance is more demanding. Other stainless grades can be reviewed when wear resistance, hardness, or cost target is important.
Can these parts be ordered in small batches?
Small batch and bulk RFQ support can be reviewed. Send quantity, drawing, and material requirements so CXE can confirm feasibility and quotation details.
