PEEK Bushings Manufacturer | Custom CNC Machined PEEK Parts Supplier

Quantity:



PEEK bushings are precision bearing sleeves used where heat, chemicals, wear, corrosion, or limited lubrication restrict the use of conventional polymers and metals. A machined PEEK bushing can support radial load, guide a shaft, isolate dissimilar metals, reduce noise, and protect expensive housings from wear.

PEEK Bushings

JUTAI manufactures custom PEEK bushings, sleeve bearings, flanged bushes, guide bushes, and wear sleeves from customer drawings. Material grade is selected according to load, speed, temperature, lubrication, counterface finish, chemical exposure, and allowable clearance. Natural PEEK provides balanced mechanical and electrical properties, while carbon-filled PEEK is often evaluated for greater stiffness, creep resistance, and tribological performance. Glass-filled PEEK can serve static or lightly moving applications where rigidity and dimensional stability are priorities. Accurate bore size, concentricity, wall thickness, flange geometry, and running clearance are critical because plastic bearings respond differently from metal as temperature and moisture change. JUTAI supports prototype qualification and repeat production, including close-tolerance turning, milling of lubrication features, and grinding where specified.

JUTAI supplies peek bushings, custom peek bushings components, and precision CNC machined high-performance plastic parts to drawing. Buyers seeking a peek bushings manufacturer, custom machining supplier, or engineered PEEK and PEI parts partner can submit CAD files for review.

Key Features

High-temperature bearing performance beyond common engineering plastics
Chemical and corrosion resistance in pumps, valves, and process equipment
Low-friction and wear-grade options for dry or lubricated operation
Electrical isolation and protection against galvanic contact
Custom flanged, split, grooved, thin-wall, and stepped designs
Low moisture absorption for stable running clearance
Reduced mass, noise, and shaft damage compared with selected metal bushings

Material Selection

Bushing grade decisions should follow bearing pressure, sliding velocity, shaft finish, lubrication, temperature, alignment, and allowable clearance change. The strongest grade is not automatically the best running surface.

Material Grade	Engineering Characteristics	Application Fit
PEEK Natural	Natural PEEK balances toughness, low moisture response, chemical resistance, and electrical isolation.	Fits moderate-load sleeves, clean equipment, and applications where an unfilled bearing surface is preferred.
PEEK CF30	Carbon fiber improves modulus, compressive behavior, creep control, and thermal transport through the bearing wall.	A strong candidate for higher-load bushings after shaft hardness and abrasive interaction are considered.
PEEK GF30	Glass-filled material produces a rigid sleeve with restrained thermal expansion and good static dimensional retention.	More appropriate for structural pivots or low-motion guides than for every continuous sliding duty.
ESD PEEK	Static-dissipative PEEK allows a bearing location to discharge accumulated electrical charge.	Relevant to rollers, pivots, and guides in electronic production equipment with a defined grounding concept.
PEI ULTEM 1000	ULTEM 1000 offers an insulating, lightweight sleeve material for lower bearing temperatures and intermittent movement.	Consider for light-duty pivots, instrument supports, or mechanisms benefiting from amber translucency.
PEI ULTEM 2300	Glass-filled PEI increases radial stiffness and reduces deformation around a press fit.	Useful for rigid insulating supports where sliding wear is secondary to positional stability.

Manufacturing Capability

Bushing production begins with the fit system. Bore size, wall thickness, flange face, lead-in, and inspection temperature are coordinated so the sleeve can be assembled without unintended distortion.

CNC turning: plain, flanged, stepped, and split-style bearing sleeves with controlled concentricity
Boring and reaming: finished internal diameters matched to specified clearance or press-fit strategy
Milling: lubrication slots, flats, anti-rotation keys, cross holes, and mounting details
Face finishing: flange thickness and shoulder squareness referenced to the functional bore
Custom batches: replacement bushings or new designs manufactured from drawings and operating data

Typical Applications

Pump and valve shaft guides
Reciprocating compressor and actuator bushings
Aerospace linkages and lightweight pivots
Semiconductor and clean-process automation
Food, beverage, and packaging machinery using qualified grades
Automotive, e-mobility, and industrial drive systems

Technical Advantages

Clearance review can account for shaft size and operating temperature
Bore and outside diameter are planned from shared rotational datums
Flanged and thin-wall forms can use dedicated soft support during cutting
Filled grades are evaluated against shaft wear instead of selected by strength alone
Inspection reports can identify bore, runout, flange thickness, and overall length
JUTAI has spent 15 years machining high-performance plastics for wear, medical, and industrial assemblies. Its material range includes Victrex PEEK, SABIC ULTEM PEI, PSU, and PI, while qualified bushing dimensions can be controlled to ±0.005 mm when size, stability, and measurement access support that tolerance.

FAQ

What is a PEEK bushing?

A PEEK bushing is a cylindrical or flanged plain-bearing sleeve that supports a shaft, pin, or pivot while separating moving surfaces.

Why replace a metal bushing with PEEK?

PEEK can eliminate corrosion, provide electrical isolation, reduce noise and weight, and run with limited lubrication in a properly engineered bearing system.

Can JUTAI manufacture custom PEEK bushings?

Yes. JUTAI turns custom bores, outside diameters, flanges, grooves, and anti-rotation features according to the drawing and required fit.

Which PEEK grade works best for a bushing?

Natural PEEK suits balanced or clean duty, whereas carbon-filled material supports greater stiffness and load. Shaft condition, PV value, and lubrication determine the final grade.

Which dimensions are critical when requesting a quote?

Include shaft diameter, installed bore clearance, housing fit, flange geometry, load direction, speed, temperature, lubricant, and mating-surface specification.

Request a Custom Machining Review

Send the bushing drawing together with load, speed, shaft material, lubrication method, and installation fit. JUTAI will review grade, machining allowance, tolerance feasibility, and inspection temperature.
