Description
Rubber Parts for Agricultural Machinery
Barbieri Rubber produces rubber parts for agricultural machinery: bellows for joysticks and levers, bellows for hydraulic cylinders, anti-vibration feet, pads, flat seals, caps, grommets and accessories for tractors, harvesters, self-propelled equipment, sprayers and farm implements. Production includes standard catalog rubber components and custom-designed products for agricultural machinery manufacturers.
Typical agricultural machinery requirements
Agricultural machinery uses rubber components in severe conditions: prolonged outdoor exposure, UV, abrasive dust, mud, lubrication oils, fuels, temperature swings from -30 to +120 °C, vibration and long operating cycles. Protection of moving parts is critical for field reliability. Joystick and control-lever bellows must resist intense external contamination.
Most requested agricultural machinery components
Most requested sector components: bellows for joysticks and hydraulic pilot levers, modular and cone bellows for lifting and handling hydraulic cylinders, anti-vibration feet for cabs, engines and pump units, bumper pads, flat seals for hydraulic pumps and fittings, caps and protections, grommets for electrical cabinets and wire harnesses, elastic closures for technical accesses.
Typical compounds for agricultural machinery
EPDM for outdoor exposure, UV and ozone. NBR for mineral and hydraulic oils. HNBR for heavy-duty hydraulics with high temperatures. NR/SBR for anti-vibration and pads. VMQ silicone for extended temperature range. Choice depends on fluid, exposure and stress type: agricultural machinery typically combines several compounds on different components of the same machine.
| Compound | Temperature range | Feature | Typical applications |
| NBR (Nitrile) | -40 / +130 °C | Mineral oil resistance | Hydraulics, automotive |
| EPDM | -40 / +100 °C | Water, steam, ozone, UV | Hydraulics, outdoor, photovoltaic |
| VMQ (Silicone) | -60 / +200 °C | High temperature | Food, high-T |
| FKM (Viton®) | -10 / +180 °C | Aggressive oils, solvents | Chemical, automotive, hydraulics |
| HNBR | -20 / +160 °C | Oil + high temperature | Heavy-duty hydraulics |
| NR / SBR | -50 / +90 °C | Mechanical elasticity | Anti-vibration, general |
Standard and custom agricultural components
Most agricultural machinery components are available as catalog rubber items, with short lead times and no tooling cost. For tractor, harvester and self-propelled equipment manufacturers we produce items on drawing with dedicated tooling: at least a preliminary drawing from the customer is required. The dedicated mold is manufactured in cooperation with our trusted toolmaking partners.
Frequently asked questions
Which agricultural components are available from stock?
Joystick bellows, modular and cone bellows for cylinders, anti-vibration feet, pads, flat seals, grommets, elastic closures, caps. Most recurrent sizes are standard catalog items, with no tooling cost for the customer.
Which compound for outdoor exposure?
EPDM is the reference compound for UV, ozone, water and atmospheric agents. For combined oil exposure, NBR or HNBR are evaluated. For extended temperature range VMQ silicone.
Do you make bellows for hydraulic lifting cylinders?
Yes. Modular and cone bellows are catalog items for hydraulic lifting cylinders. For special sizes or geometries we produce custom versions.
Do you produce custom items for OEM manufacturers?
Yes. For tractor, harvester and self-propelled equipment manufacturers we produce dedicated items on drawing. At least a preliminary drawing from the customer is required. The dedicated mold is manufactured in cooperation with our trusted toolmaking partners.
Which quality standards do you follow?
ISO 9001 certified production with compound traceability and process control. Conformity documentation for OEM agricultural-machinery suppliers on request.
