Welcome to Hengshui Ruibin New Materials LLC – your trusted manufacturer of high-performance elastomeric components. Our Precision Rubber Bearing with Steel Core, 15mm ID x 30mm OD is engineered to deliver exceptional dimensional accuracy and reliable performance in demanding applications. With tolerances held to ±0.1mm, this bearing ensures consistent fit and function, reducing assembly issues and extending service life. Since 2019, we have been dedicated to producing quality rubber-metal bonded parts, exporting to markets across North America, Europe, Asia, and beyond.
This bearing combines a durable rubber compound with a precision-machined steel core to provide excellent vibration damping, noise reduction, and load-bearing capacity. The 15mm inner diameter and 30mm outer diameter make it suitable for a wide range of mechanical assemblies, including conveyor systems, agricultural equipment, industrial pumps, and automotive components. Our manufacturing process ensures tight control over dimensions, with each piece inspected to meet the ±0.1mm tolerance specification.
Key Features & Benefits:
- Precision Tolerances ±0.1mm – Guarantees consistent fit and interchangeability, minimizing downtime during installation.
- Steel Core Reinforcement – Provides high strength and rigidity, allowing the bearing to withstand heavy radial and axial loads.
- Elastomeric Damping Layer – Reduces vibration and noise, protecting sensitive equipment and improving operator comfort.
- Wide Temperature Range – Standard compound operates from -40°C to +120°C; optional high-temperature formulations available.
- Corrosion Resistance – Steel core is treated with anti-rust coating; rubber is resistant to oils, greases, and mild chemicals.
- Customizable Hardness – Available in Shore A 60 to 90 to suit specific stiffness requirements.
- Low Friction – Optimized rubber surface reduces friction against mating parts, extending service life.
- Easy Installation – Standard dimensions allow direct replacement of existing bearings in many applications.

Frequently Asked Questions (FAQ)
-
Q: What is the typical lead time for this bearing?
A: Standard lead time is 15–25 working days after order confirmation. For custom specifications, please allow additional 5–10 days for tooling and sampling. -
Q: Can you provide samples before mass production?
A: Yes, we offer samples for evaluation. Sample cost is negotiable and can be deducted from the first order. -
Q: Is the steel core rust-proof?
A: Standard carbon steel cores are treated with anti-rust coating. For higher corrosion resistance, we recommend stainless steel cores (optional). -
Q: What rubber materials are available?
A: We offer natural rubber (NR), SBR, NBR, EPDM, and silicone rubber. Each has different oil, temperature, and abrasion resistance. Please specify your operating conditions. -
Q: Do you offer custom dimensions beyond 15mm x 30mm?
A: Absolutely. We can produce rubber bearings with any ID/OD combination within our manufacturing capabilities. Provide your drawing or specifications for a quote. -
Q: What is the minimum order quantity (MOQ)?
A: For standard sizes, MOQ is 500 pcs. For custom sizes, MOQ is 1000 pcs. Smaller quantities are available for sample orders. -
Q: How do you ensure the ±0.1mm tolerance?
A: We use precision molds and advanced compression molding processes. Each bearing is measured with digital calipers at the final inspection stage. -
Q: Can these bearings be used in food processing equipment?
A: Yes, if you select FDA-approved rubber compounds. Please contact us with your specific requirements.
