Forging Press Spare Parts: What Wears and How to Source It
For buyers in Poland, Europe and export markets, standard forging press parts such as bearings, pneumatic valves and seals are available off-the-shelf from industrial suppliers. Structural assemblies such as eccentric shafts and knuckle levers are sourced through the original manufacturer, specialist machine-tool suppliers or remanufacturing. This guide explains how to separate mechanical forging press parts that you can buy quickly from parts that need drawings, samples, reverse engineering or a donor machine.

What Wears on a Forging Press?
Clutch and brake linings
Friction linings wear with every engagement. Pneumatic clutch and brake systems also need clean air supply, working pressure switches and reliable valves.
Knuckle pins and bushings
Knuckle joint presses load pins and bushings heavily near bottom dead centre. Excessive play changes slide position and reduces forging accuracy.
Slide guides and gibs
Guide faces, gibs and wear strips take side load from imperfect die alignment. Worn guides increase die wear and can make trimming or coining inconsistent.
Main shaft plain bearings
Large plain bearings on Soviet-era presses can wear, score or lose bearing metal. Remetalling the bearing shells is a common repair route.
Electrical cabinet components
Original electrical cabinets from the 1970s and 1980s usually need replacement before production. Contactors, relays, wiring insulation and safety circuits age even when the press stands idle.
Which Parts Are Off-the-Shelf and Which Are Manufacturer-Specific?
Off-the-shelf components
Bearings, pneumatic valves, seals, pressure switches, hoses and standard motors are usually bought from industrial component suppliers. Match dimensions and duty rating before ordering.
Factory assemblies
Eccentric shafts, knuckle levers, connecting rods, frame parts and large drive elements are model-specific. These parts need the original manufacturer, a specialist supplier or a rebuild shop.
Remanufactured parts
Repair firms can remetall plain bearings, grind shafts, make pins and bushings from a sample, and restore worn fits when new parts are not practical.
Drawings and documentation
Factory drawings shorten the sourcing process. Before buying a used press, check whether the machine documentation includes parts lists, assembly drawings and electrical diagrams.
Where Can You Source Parts by Brand?
TMP Voronezh
TMP Voronezh operates today as JSC Tjazhmekhpress and remains Russia's principal heavy mechanical press manufacturer, currently building presses up to 16,500 tonnes-force. The factory can supply parts for older TMP models directly.
Smeral Brno
Smeral Brno has manufactured forming machines since 1861 and remains an active, ISO 9001-certified manufacturer. The factory maintains an online spare parts inventory system for its press models, so original documentation and components for Smeral presses are traceable directly through the manufacturer.
Barnaul
Major Barnaul drive components usually come through specialist Eastern European machine-tool suppliers. Standard bearings and pneumatic parts are off-the-shelf.
Soviet press repair firms
For spare parts for Soviet forging presses, use repair firms and millwrights who know Soviet mechanical press construction. They can assess whether the practical route is a supplier, a drawing, a sample or a rebuild.
What Should You Check Before Buying a Used Press?
Check completeness during inspection
Confirm guards, lubrication parts, clutch elements, control gear, die clamps and documentation before purchase. Use a written forging press inspection checklist so missing small parts do not delay commissioning.
Consider a donor machine
Buying a second worn or incomplete machine as a parts donor is common for old Soviet and Eastern European presses. It can solve model-specific drive and frame component problems.
Budget for electrical replacement
Treat the electrical cabinet as a planned project, not a surprise repair. Old cabinets rarely meet production expectations after decades of use and storage.
Verify documentation language
Ask what manuals, drawings and electrical diagrams come with the press and note the language before buying. Soviet-era documentation is often in Russian.
Frequently Asked Questions
No. TRIGA sells machines as found and does not supply spare parts. The spare parts catalogue lists only positions that actually exist; currently these are Smeral LZK 4000 components at /spare-parts.
Yes. Remetalling plain bearings and making pins or bushings from a sample are normal jobs for repair firms familiar with heavy mechanical presses.
It depends on the machine. We pass on the documentation that comes with the press and state the language and completeness; Soviet-era documentation is usually in Russian.
Clutch and brake linings, pneumatic valves, knuckle bushings and slide guides are common wear points. Electrical components often need replacement because of age.
If a seller transfers a machine with spare parts, those parts are listed with that specific machine. TRIGA does not add separate spare parts packages.
Looking at a press with missing parts?
Send the model, nameplate photo and close-up photos of the missing parts. We will tell you what is realistic to find and what usually drives the lead time.
