Sill Bearing
High-performance components engineered for durability and precision.
SILL BEARING FACTORY is strategically located in the Hangzhou Bay New Zone, a global hub for industrial precision. Our proximity to the Shanghai and Ningbo Ports ensures that our wholesale partners benefit from reduced lead times and optimized logistics, connecting China's manufacturing heart to the world.
To meet the rising global demand for 6000 series bearings, our new facility—Anhui TOPB IMP.&EXP. Co., Ltd.—is expanding our capacity. Once operational, it will boost our annual production by $20 million, ensuring we remain the most reliable factory for high-volume wholesale orders.
We utilize superior GCr15 bearing steel across our range (￠4mm ～￠120mm). This high-carbon chromium steel provides the extreme hardness and wear resistance required for the 6005z's 25x47x12mm architecture, ensuring longevity under high radial loads.
The 6005z bearing is not merely a commodity; it is a critical component in the evolution of automation. Our technical roadmap focuses on four key dimensions: Friction Reduction, Noise Mitigation, Smart Sealing, and Material Integrity.
Our 6005z series is engineered for applications requiring silent operation. Through advanced grinding of the raceways, we achieve vibration levels that meet V3 standards, ideal for high-end household appliances and medical motors.
Moving beyond standard P0 (ABEC-1), our factory offers P6 and P5 (ABEC-3/5) tolerances for wholesale clients who demand higher rotational accuracy for CNC machinery and high-speed spindles.
By partnering with global lubricant leaders (Mobil/Shell), our 6005z bearings come pre-filled with high-temp grease that extends service life by 30% compared to generic alternatives.
As we transition toward Industry 5.0, SILL BEARING is researching sensor-integrated bearings. These components will monitor temperature and vibration in real-time, providing predictive maintenance data to operators—a crucial leap for factories looking to eliminate unplanned downtime.
In the modern era, a "Bearing Factory" must be more than a production line; it must be a resilient node in a global ecosystem. Our Hangzhou Bay facility operates on Industry 4.0 principles, utilizing automated CNC grinding, ultrasonic washing, and AI-driven visual inspection.
Used in alternators, starters, and EV powertrain cooling fans, the 6005z provides the reliability needed for 10+ years of vehicle life.
In conveyor systems and robotic arms, these bearings ensure smooth motion with minimal maintenance requirements.
The "Z" shielding protects the internal raceway from dust and soil, making it a staple for harvesters and tractors.
Found in washing machines, vacuum cleaners, and air conditioners where low noise (V-grade) is the primary user requirement.
Versatile, self-retaining bearings with deep groove raceways. Ideal for both radial and axial loads, low friction, and high-speed efficiency.
Designed with tapered raceways in inner and outer rings. Available in single, double, and four-row configurations to handle massive heavy-duty loads.
Engineered for high-speed precision and large one-way axial loads. The contact angle determines the load-bearing threshold.
Compact structure with high rotation precision. These are essential for applications where space is limited but high radial capacity is required.
SILL BEARING caters to the stringent requirements of international procurement. Our bearings are exported to the U.S., Brazil, Switzerland, UAE, Turkey, Malaysia, and beyond. We understand that global trade requires more than just a good product—it requires Reliability (E-E-A-T).
Compliance Matrix:
- ISO 9001:2015 Quality Management Standards
- RoHS & REACH Material Compliance for EU Markets
- OEM & NETB Brand Support for Regional Customization
Expert insights into 6005z bearing selection and wholesale procurement.
The 6005z bearing is a deep groove ball bearing with an inner diameter of 25mm, an outer diameter of 47mm, and a width of 12mm. The 'z' suffix indicates it is equipped with a single metal shield for protection against dust.
Sourcing directly from a China factory provides the benefit of "Information Gain" through factory-direct technical support, competitive wholesale pricing, and the ability to customize tolerances (P6/P5) and noise grades (V2/V3) that trading companies cannot offer.
Yes. We operate our own brands SILL and NETB, but we are a primary OEM partner for several global distributors, providing customized packaging, laser marking, and specific grease formulations.
We employ a 5-step rigorous inspection protocol. Every batch of GCr15 steel is tested for chemical composition before production, and finished products undergo 100% noise and vibration testing before being shipped to global markets.
Due to our location in the Hangzhou Bay New Zone near major ports and our massive production capacity, standard orders are typically fulfilled within 15-30 days, depending on customization requirements.
