The W2000 H311 Bearing Bush (PN.1395) is a precision-engineered bearing accessory designed to act as a critical interface between rotating shafts and adapter sleeves (e.g., H311 series). Manufactured in China by JST, a supplier with expertise in bearing components, this product adheres to global quality benchmarks, ensuring compatibility with diverse industrial equipment. Its primary function is to reduce mechanical wear, stabilize power transmission, and enhance the overall operational efficiency of machinery—making it a staple in both standard and heavy-duty applications.
The PN.1395 Bearing Bushing features an optimized structural design with precise inner/outer diameter tolerances (complying with ISO 8124 standards). Its compact profile minimizes space occupation in equipment assemblies, while the ultra-smooth surface finish (Ra ≤ 0.8μm) reduces friction during high-speed rotation. Additionally, the bushing’s integrated sealing groove (optional for custom orders) allows for easy integration of dust or oil seals, preventing contaminants from entering and extending the service life of both the bushing and connected components.

The core structure of the W2000 H311 Bearing Bush is crafted from high-carbon chromium steel (SUJ2/SCM440) —a material selected for its exceptional mechanical properties. After heat treatment, the steel achieves a hardness of HRC 58-62 , ensuring resistance to deformation under high pressure. It also maintains stability across a wide operating temperature range (-20°C to 120°C), making it suitable for environments with fluctuating thermal conditions. This material meets ASTM A295 standards, guaranteeing consistent quality and reliability in industrial use.
To enhance corrosion resistance, the PN.1395 Bearing Bushing undergoes a triple-layer Zn-Ni alloy plating process. This coating forms a protective barrier against moisture, industrial oils, and dust, extending the product’s lifespan in harsh environments (e.g., mining, marine). The plating is RoHS-compliant, making the bushing safe for eco-sensitive industries like food processing and medical equipment manufacturing. For specialized applications (e.g., high-temperature machinery), an optional ceramic coating (Al₂O₃) is available to further boost heat resistance.
Low Friction & Energy Efficiency : The W2000 H311 Bearing Bush boasts a friction coefficient of ≤0.08 , significantly reducing energy loss in rotating systems (e.g., electric motors). This translates to improved fuel efficiency for vehicles and lower electricity consumption for industrial machinery.
High Load-Bearing Capacity : It supports a static load capacity of up to 50kN and a dynamic load capacity of up to 32kN , enabling it to withstand heavy mechanical stress in applications like construction cranes and truck transmissions.
Vibration Resistance : The precision design and high-hardness material minimize vibration during operation, reducing noise and preventing damage to adjacent components (e.g., gearboxes).
Easy Installation : The PN.1395 Bearing Bushing fits standard adapter sleeves (ISO 8124) and requires only basic tools (torque wrench, socket set) for installation—no custom machining or specialized equipment is needed. This cuts down on maintenance downtime by up to 40% compared to non-standard bushings.
Low Maintenance Requirements : Routine maintenance only involves lubrication with lithium-based grease (NLGI Grade 2) every 500 operating hours. The corrosion-resistant coating also eliminates the need for frequent cleaning or anti-rust treatments.
Thanks to its high-quality material and strict manufacturing controls, the W2000 H311 Bearing Bush delivers an extended service life of up to 8000 operating hours under normal conditions. It exhibits excellent fatigue resistance, withstanding repeated mechanical cycles without cracking or excessive wear—lowering replacement costs and improving long-term operational stability for end-users.
The PN.1395 Bearing Bushing is widely used in key industrial machinery, including:
Electric Motors & Pumps : Installed in motor shafts and centrifugal pump rotors to reduce friction and prevent leakage, ensuring continuous operation in water treatment plants and manufacturing facilities.
Conveyor Systems : Supports conveyor belt rollers in factories, enabling smooth transportation of raw materials (e.g., steel coils) and finished products (e.g., electronics) with minimal downtime.
In the automotive and transportation sector, it is a reliable choice for:
Heavy-Duty Vehicles : Used in truck transmission systems and trailer axle assemblies, where its high load capacity and vibration resistance ensure stable power transfer on rough roads.
Commercial Vans : Compatible with light commercial vehicle drivetrains, contributing to improved fuel efficiency by reducing mechanical resistance.
For harsh industrial environments, the W2000 H311 Bearing Bush is ideal for:
Construction Machinery : Installed in excavator arm joints and crane hoist shafts, withstanding high torque and impact forces during digging or lifting operations.
Mining Equipment : Its corrosion-resistant coating protects against dust and mineral-rich water, making it suitable for mining drill bits and conveyor systems in underground mines.
Q: Is the W2000 H311 Bearing Bush compatible with adapter sleeves outside the H311 series?
A: Yes, the PN.1395 Bearing Bushing works with most standard adapter sleeves meeting ISO 8124 dimensions, including H310, H312, and H313 series. For non-standard sleeves, our technical team can provide custom fit checks—simply share your sleeve’s inner diameter and shaft tolerance for verification.
Q: Can improper installation damage the PN.1395 Bearing Bushing , and how to avoid this?
A: Over-tightening (exceeding 80 N·m torque) or misalignment can cause cracks in the bushing. To avoid this, use a torque wrench to follow the recommended tightening torque (65-75 N·m for steel shafts) and ensure the shaft is clean (free of burrs) before installation. For maintenance, avoid high-pressure water cleaning—this may strip the zinc plating and expose the bushing to corrosion.
Q: Does the China-manufactured W2000 H311 Bearing Bush meet international quality standards?
A: Absolutely. Each PN.1395 Bearing Bushing undergoes 100% quality inspection, including material spectrometry (for steel composition), Rockwell hardness testing, and dimensional checks (via CNC measuring tools). It holds ISO 9001 (quality management) and CE (European safety) certifications, ensuring compliance with global industrial requirements. Every unit also passes a load test and leak test before shipment.
Q: What is the minimum order quantity (MOQ) for the W2000 H311 Bearing Bush , and how long is delivery?
A: The standard MOQ is 10 units; for bulk orders (500+ units), flexible MOQs and wholesale pricing are available. Domestic (China) delivery takes 3-5 working days, while international shipping takes 7-15 working days (depending on destination—e.g., 7 days for Southeast Asia, 12 days for Europe). We also offer anti-rust packaging for international orders to prevent damage during transit.
