Reliable spacing and alignment across millions of cycles
Packaging equipment operates under continuous mechanical stress, high cycle rates, and strict alignment requirements. High-speed form-fill-seal machines, rotary cappers, automated case packers, and labeling systems depend on exact spacing and rigid mechanical support to maintain timing, prevent jam-ups, and reduce premature component wear.
SpacerMFG works directly with packaging machinery OEMs, automation integrators, and equipment rebuilders to deliver print-to-part components for rigorous production environments.
Technical demands
Components engineered for dynamic packaging machinery
Linear actuators, indexing tables, conveyor drives, and pneumatic pushers operate across millions of continuous cycles. Precision spacers and sleeves help preserve structural integrity in these moving assemblies.
Parallelism and flatness
Flat, parallel end faces distribute axial loads and help prevent shaft binding, angular deflection, and fatigue.
Controlled wall thickness
Consistent geometry supports concentric load sharing across sleeves, bushings, and stacked components.
Corrosion resistance
Material and finish options withstand washdowns and chemical exposure in food, beverage, and pharmaceutical lines.
Wear and friction control
Specified finishes and hardness help guide surfaces resist galling during high-velocity linear movement.
CNC machining capabilities
From precision spacers to complete automation components
SpacerMFG operates dedicated CNC turning and milling lines for low-to-high volume production. Components are manufactured according to customer-supplied CAD models, prints, and tolerance specifications.
Send Your DrawingPrecision spacers
Round, square, or hex profiles with controlled ID, OD, and length tolerances.
Sleeves and bushings
Thin- or heavy-wall cylindrical parts for shaft protection, bearing support, and mechanical separation.
Stepped and flanged spacers
Integrated shoulders and flanges simplify assembly and provide positive locating stops.
Threaded spacers and standoffs
Internal, external, or combined threads for sensors, frames, and control panels.
Custom turned and milled parts
Shafts, pins, mounting blocks, guide rails, and brackets designed for packaging automation.
| CNC turning | OD, ID, steps, grooves, chamfers, threads |
|---|---|
| CNC milling | Pockets, slots, holes, counterbores, profiles |
| Primary tolerances | Per customer drawing specifications |
| Secondary processes | Drilling, reaming, tapping, grinding, deburring |
Material selection
Match materials and finishes to the machine zone
The correct material and surface treatment depends on whether a component operates in a dry frame, sanitary washdown zone, or high-speed indexing mechanism.
| Material category | Typical grade | Primary application |
|---|---|---|
| Stainless steel | 304 / 316L | Washdown zones, filling heads |
| Stainless steel | 17-4 PH | High-stress indexing drives |
| Aluminum | 6061-T6 / 7075-T6 | Reciprocating arms, end-effectors |
| Carbon steel | 1018 / 1045 / 4140 | Internal drive frames, rollers |
| Brass / bronze | C360 / C932 | Low-friction sleeve bushings |
| Engineering plastics | POM / PEEK | Non-marring container guides |
Passivation
For stainless components exposed to humid, acidic, or food-contact environments.
Anodizing
Type II and Type III hardcoat options for wear protection and identification.
Electroless nickel
Uniform coverage for bores and complex threads with added hardness.
Protective plating
Black oxide and zinc plating for internal structural steel parts.
Laser marking
Part numbers, serial numbers, and batch codes for traceability.
Application guide
Component recommendations by packaging zone
Dry conveying
For cartoners, case packers, and palletizers, carbon steel and aluminum spacers provide rigid frame spacing, conveyor shaft positioning, and sensor bracket mounting where structural loads and vibration matter more than chemical exposure.
Washdown and sanitary
Liquid fillers, thermoformers, and pouch-sealing equipment benefit from passivated 304 or 316L stainless steel with smooth radii and zero-crevice geometry to limit liquid collection, bacterial growth, and chemical corrosion.
High-speed indexing
Pick-and-place grippers, flying cut-offs, and rotary turret indexers require low mass and tight length parallelism. Hardcoat-anodized 6061-T6 or 7075-T6 aluminum supports rapid acceleration and deceleration.
Quality assurance
Verified for seamless drop-in assembly
Every production lot is inspected against customer 2D and 3D drawings. Quality controls verify flatness, perpendicularity, thread pitch, surface finish uniformity, and coating thickness.
