Pillow block bearing
Industrial-Grade Pillow Block Bearings – Global Export Solution
Product Overview
Pillow block bearings (also known as plummer block bearings or insert bearings with housings) are essential mechanical components designed for easy installation, self-alignment, and reliable operation in harsh industrial environments. Our product range covers two core categories: Insert Bearings (ball/roller type, with spherical outer diameter) and Integrated Pillow Block Housings (cast iron, ductile iron, or stainless steel材质), available in UCP, UCF, UCT, UCC, UCFL, and other international standard series. Widely applied in General Machinery, Agricultural Equipment, Construction Machinery, Conveyor Systems, and HVAC Equipment, our pillow block bearings are compatible with ISO, DIN, ANSI, and JIS standards, meeting the operational demands of global clients across Europe, North America, Southeast Asia, and the Middle East.
Core Technical Advantages
1. Exceptional Adaptability & Self-Alignment
– The spherical outer diameter of insert bearings enables ±2° self-alignment, compensating for shaft deflection and installation errors, which significantly reduces premature wear caused by misalignment.
– Housings are precision-machined with optimized internal cavities to ensure perfect fit with insert bearings, enhancing load distribution and rotational stability. For high-vibration applications, we offer reinforced ribbed housings that improve structural rigidity by 35%.
– Temperature resistance ranges from -30℃ to 150℃ (standard version) and -50℃ to 200℃ (high-temperature version with special grease), adapting to extreme working conditions such as outdoor agricultural machinery and high-temperature industrial furnaces.
2. Robust Durability & Contamination Resistance
– Insert bearings are manufactured from high-quality GCr15 bearing steel (ISO 683-17) with precision grinding and heat treatment, achieving a hardness of HRC 60-64 and a surface roughness of Ra ≤0.08μm, ensuring long-term wear resistance.
– Equipped with double-lip seals (nitrile rubber or Viton) and pre-filled with high-temperature lithium-based grease, the sealed structure effectively blocks dust, dirt, moisture, and corrosive substances, extending maintenance-free service life by 60% compared to standard products.
– Housings are made of HT200 gray cast iron (standard), QT450 ductile iron (heavy-duty), or 304 stainless steel (corrosion-resistant), with electrophoretic coating or galvanizing treatment to prevent rust and corrosion in humid or outdoor environments.
3. Easy Installation & Maintenance
– Standardized mounting holes and bolt sizes (compatible with DIN 933/934 and ANSI B18.2.1) enable direct replacement of brand-name products (SKF, NSK, NTN equivalents), reducing replacement costs and downtime.
– Split-type housing design (available for large-size models) allows for quick bearing replacement without disassembling the entire equipment, improving maintenance efficiency by 40%.
– Comprehensive product markings include part number, load rating, speed limit, and manufacturing date, facilitating inventory management and traceability for overseas distributors.
4. Global Certification & Quality Assurance
– Fully compliant with ISO 9001:2015, IATF 16949 (for automotive-related applications), and CE certifications, meeting the quality requirements of global industrial markets.
– Passed rigorous performance tests including fatigue life test (L10 life ≥10,000 hours at rated load), water resistance test (IP65 protection level), and high-speed rotation test (up to 5,000 rpm for ball-type bearings), ensuring consistent quality in mass production.
