Selecting the appropriate type of rubber bush is a function of selecting the material characteristics of the bush and matching them with the application requirements in order to ensure the long-term effectiveness and cost-effectiveness of the application. The following are the procedures to follow in selecting the appropriate type of rubber bush in accordance with the engineering standards set.
Step 1: Assess Load Capacity
Determine the radial and axial loads, such as 500-1000kg for a mining truck, and apply a safety factor of 2.5-4 times in dynamic applications. Conical bushes are used in the distribution of weights evenly, and the cylindrical type is used in the application of uniform pressures.
Step 2: Evaluate Environment
The nitrile oil/chemicals used in the production of the bushes have an oil swell of less than 10%.
UV/Coastal: EPDM (1,000h Resistant - ASTM G154)
Temperature Range: Silicone (-55°C - 230°C)
Temperature range: Ensure compliance with ASTM D2000 for -40°C - 150°C.
Step 3: Check Dimensions & Fit
Measure diameters of 20-200mm with tolerances. Match OEM specifications for deflection and hardness.
Step 4: Review Testing and Certifications
The tensile strength must be ≥15 MPa, elongation ≥300% (as per ASTM D412), and compression set <25% (in accordance with ASTM D395). The ISO 9001:2015 standard guarantees the integrity of bonds.
Step 5: Installation and Maintenance Requirements
Opt for designs that utilise a simple press-fit mechanism, taking torque specifications into account. Test samples under maximum load first.

Sources: ASTM D2000; DuPont/Dow
1. What is the best rubber bush material for mining applications?
For mining in South Africa, nitrile rubber bushes are typically the best choice because they resist oils, hydraulic fluids, and abrasion, with tensile strength. This makes them ideal for conveyor idler bushes, chassis mounts, and hydraulic‑cylinder joints in Johannesburg‑based mines.
2. Which rubber bush is oil-resistant?
Nitrile rubber bushes provide the best oil and fuel resistance among standard elastomers. They are commonly used as oil‑resistant rubber bushings for engine mounts, hydraulic‑system bushings, and automotive fuel lines, where they maintain load‑bearing capacity and low compression set when exposed to petroleum‑based fluids.
3. Are EPDM rubber bushes suitable for outdoor use?
Yes, EPDM rubber bushes are highly suitable for outdoor and coastal environments because EPDM offers excellent UV and ozone resistance, as well as good weathering performance up to around 1,000–1,500 hours in accelerated‑weathering tests. In South Africa, these bushes work well in Cape Town’s coastal HVAC systems, construction‑site machinery, and outdoor power‑cabinet mounts.
4. Do you export rubber bushes across Africa?
Yes, we export rubber bushes to other African markets, mainly via FOB Durban or CIF terms, with full commercial invoice, certificate of origin (COO), and any required fumigation or customs documentation. Shipment lead times for African destinations are typically 10–14 days, subject to local ports and customs clearance
5. Can you manufacture custom rubber bushes?
Yes, we manufacture custom rubber bushes to OEM and end‑user specifications. Using CAD‑based design and in‑house tooling, we can produce tailor‑made rubber bush profiles with specific inner and outer diameters, wall thickness, hardness, and material (nitrile, EPDM, natural rubber, etc.)
6. What hardness options are available for rubber bushes?
Our rubber bushes cover a Shore A hardness range of about 40–90, depending on material and design. Softer bushes are used where high vibration damping and low‑noise isolation are required, while harder compounds are selected for high‑load, high‑compression‑resistance applications such as heavy‑duty mounting systems.
7. What is the lifespan of rubber bushes?
Under typical operating loads and ambient conditions, nitrile, EPDM, and natural‑rubber bushes commonly achieve service lives of 5–10 years, depending on material, environment, and maintenance. For example, EPDM bushes in UV‑stable outdoor installations may reach the upper end of this range, while heavily loaded nitrile bushes in abrasive mining environments may fall toward the lower end. Regular inspection and correct mounting reduce early‑failure risk.
8. Are rubber bushes suitable for high‑load machinery?
Yes, rubber bushes can be engineered for high‑load machinery when designed with high‑strength compounds, optimized wall thickness, and load‑distribution geometry (such as conical or reinforced designs). Depending on size and material, our bushes can withstand compression loads of several hundred kilograms per unit, while maintaining vibration‑damping and noise‑reduction benefits.
9. How do rubber bushes reduce vibration?
Rubber bushes reduce vibration by acting as elastomeric springs that absorb and dissipate mechanical energy. When force is applied, the rubber deforms elastically, converting kinetic energy into low‑level heat and damping oscillations before they reach connected components. This principle helps reduce noise, minimizes fatigue in metal structures, and extends bearing and joint life in vehicles and industrial equipment.
10. What industries use nitrile rubber bushes?
Nitrile rubber bushes are widely used in the automotive, mining, and oil & gas sectors because of their resistance to oils, fuels, and hydraulic fluids. Typical applications include vehicle suspension and steering bushes, hydraulic‑cylinder joints, pump and motor mounts, and mining‑equipment connect points where lubricants are present. Durban‑based oil‑refinery and port‑logistics machinery often rely on nitrile bushes for their hydrocarbon resistance.
11. Do you offer bulk pricing?
Yes, we provide structured bulk pricing for large‑volume orders, typically from 500 units upwards. Pricing tiers are based on current material‑cost indices, tooling‑amortisation, and production‑batch efficiency, with formal quotation sheets showing per‑unit and total‑order cost. For frequent buyers, we also maintain flexible stocking and JIT‑supply options to reduce buyers’ inventory costs.
12. Can rubber bushes handle extreme temperatures?
Different rubber materials are selected for different temperature ranges.. Outside these ranges, it is necessary to switch to special compounds such as silicone‑based elastomers, which can remain flexible from -60°C to +230°C but offer different chemical‑resistance profiles.
13. Are your bushes suitable for automotive OEM use?
Yes, our rubber bushes can be developed for automotive OEM and aftermarket applications, provided the dimensional and performance requirements are clearly defined in CAD drawings and test‑specification sheets. We support OEM‑style processes such as material‑test reports, hardness‑test records, compression‑set data, and batch‑traceability documentation to meet South African and international vehicle‑supplier standards.
14. What testing standards do you follow for rubber bushes?
Our rubber bushes are tested against internationally recognised standards, depending on material and function, including:
