Bearing Bushing
A bearing bushing is a sleeve that provides a sliding surface between a shaft or pivot pin and its supporting housing. Its bore, outside diameter and end faces must work with the mating parts, lubrication method and operating conditions.
CNCPioneer machines custom bushings from specified metal or engineering plastic stock. We review the complete drawing, including wall thickness, flanges, steps, grooves and oil holes, then plan machining and inspection around the dimensions that control assembly and motion.
- Shaft and Housing FitsDefine the shaft clearance, outside-diameter fit and whether the bore is inspected before or after installation.
- Bore and Datum ControlIdentify bore size, roundness, axis relationships and flange-face requirements on the drawing.
- Material and LubricationConfirm the alloy or polymer grade together with the mating shaft, lubrication and service conditions.
- Inspection to Your DrawingAgree measuring methods, sampling, material certificates and any assembly-gauge checks with the order.
Machining Your Bearing Bushing
Plan the process around the sliding surface, installation fit and features that locate the bushing in its assembly.
Thin-Wall Workholding
Review stock allowance, clamping and machining sequence to control distortion in slender sleeves. Agree the condition in which final dimensions will be measured.
Flanges and Special Features
Machine locating shoulders, lubrication grooves, cross-holes and slots to the supplied design. Coordinate secondary milling or drilling with the turned datums.
Material-Specific Planning
Choose tooling and machining allowances for the specified material. Include heat treatment, plating or polymer conditioning in the process review where required.
Drawing-Based Inspection
Check critical bores, outside diameters, lengths and face relationships using the agreed inspection plan. Surface finish and burr condition are reviewed at functional interfaces.
Prototype and Repeat Orders
Use drawing revision, material condition and approved inspection criteria to define each order. Quantity, finishing and documentation requirements inform the quotation.
Bearing Bushings We Manufacture
Representative bushing geometries. Material, wall thickness, fit and additional features are specified for your assembly.
Plain Sleeve Bushings
Straight cylindrical sleeves for shaft and pivot interfaces. Specify bore, outside diameter, overall length and entry chamfers, together with the required installation fit.
Flanged Bearing Bushings
Flanged sleeves with an axial locating face. Define flange diameter and thickness, the mating face and any thrust-surface requirements in addition to the bore fit.
Grooved Bearing Bushings
Bushings with specified internal or external grooves. Provide groove position, profile and purpose so lubrication channels and retaining features can be machined correctly.
Stepped Sleeve Bushings
Sleeves with multiple diameters or locating shoulders. Define each mating interface and the datum relationships between the bore, outside diameters and end faces.
Slotted Bushings
Custom sleeves with a drawing-defined slot. Slot width, depth, edge condition and the free-state or installed inspection condition are reviewed before machining.
Cross-Drilled Bushings
Bushings with radial holes for a specified lubrication or assembly function. Define hole size and location, and agree deburring requirements at the bore intersection.

Bearing Bushing FAQ
What is the difference between a bearing bushing and a bearing housing?
A bearing bushing provides a sliding interface for a shaft or pivot pin. A bearing housing is the supporting body that locates a bushing or a separate bearing. This page covers custom machined sleeves and bushings.
Which bushing designs can you machine?
We review plain sleeves, flanged bushings, stepped profiles, grooves, slots and cross-drilled features against your drawing. The machining route depends on material, wall thickness, feature access and order quantity.
What information is needed to quote a custom precision bearing bushing?
Send the 2D drawing and a 3D model where available, material grade, quantity, surface requirements and delivery needs. Identify bore and outside-diameter fits, mating parts and any inspection or certification requirements.
- Include flange dimensions, lubrication features and the current drawing revision.
- State whether critical bore checks apply before or after installation.
Can you supply bushings with a specified press fit or running clearance?
We machine to the dimensions and limits agreed on the drawing. Review the shaft and housing dimensions together with material and installation conditions. Do not assume that a free-state bore measurement alone defines the final assembled clearance.
Can every bearing bushing operate without lubrication?
Lubrication requirements depend on the material system, mating shaft, load, speed and operating environment. A solid machined metal bushing should not be assumed to be self-lubricating. Identify any specified liner, lubricant inserts or porous bearing material separately so the supply and manufacturing route can be confirmed.
Which inspection records and production quantities can be quoted?
Prototype and repeat-production enquiries are reviewed individually. Material certificates, dimensional reports and customer-specific first-article records can be included in the quotation scope. Price and delivery follow review of the drawing, quantity, material availability, finishing and inspection requirements.
