Explore our core catalog of high-performance bearings engineered for reliability and long operation lifespans.
Within mechanical design, the 6007 2RS deep groove ball bearing serves as a crucial element for rotary motion. Measuring 35mm in inner diameter, 62mm in outer diameter, and 14mm in width, its standard size provides reliable load distribution and durability. The 2RS sealing configuration features dual-sided rubber seals to block dirt, moisture, and debris while retaining internal lubricants.
At SILL BEARING FACTORY, located in the Hangzhou Bay New Zone, we specialize in high-carbon chromium steel (GCr15) bearings. To support growing international demand, our new facility, Anhui TOPB IMP. & EXP. Co., Ltd., is scaling up capacity to add $20 million to our yearly output. This expansion ensures our global supply chain remains reliable and responsive.

Different systems require specific bearing geometries. We manufacture four primary types to meet varied application needs.
Versatile, self-retaining bearings with deep groove raceways that handle both moderate radial and axial loads in both directions. Features low friction, low noise, and minimal maintenance.
Separate design featuring tapered raceways on inner and outer rings. Categorized into single, double, and four-row variants to manage high thrust and radial forces.
Specifically designed to manage large single-direction axial loads. Higher contact angles enable greater overall thrust capacities for demanding industrial machinery.
Combines radial needles with thrust assemblies for a compact profile. Provides high rotational accuracy and load handling within tight space constraints.

How different industries integrate the 6007 2RS bearing into their systems to ensure long-term performance.
Electric motors require quiet operation and low vibration levels. The 6007 2RS bearing features refined raceways that minimize friction and dynamic noise. This design supports consistent energy efficiency in home appliances, ventilation fans, and light industrial equipment.
Harvester and tractor drive systems operate in dusty, outdoor environments. The dual-lip NBR rubber seals (2RS) protect the bearing's interior from soil, water, and debris, preventing premature failures and reducing maintenance requirements.
In gearboxes, alternators, and accessory drives, bearings must handle moderate axial and radial loads under cycling temperatures. The GCr15 bearing steel provides the structural stability and fatigue resistance needed for automotive systems.
To ensure consistent reliability, every production run is monitored through our strict testing protocol.
We test incoming GCr15 bearing steel using chemical spectroscopy and ultrasonic scanning to verify purity and detect hidden voids.
Machinists monitor dimensional tolerances at each grinding step, ensuring real-time control over outer/inner ring geometry.
Dedicated QA inspectors test components during assembly for roundness, groove alignment, and surface finish values.
Chief inspectors pull random samples from every batch to verify mechanical properties, clearance values, and noise limits.
Before packaging, every bearing is ran through computerized noise testers and dimensional checks. Only products meeting a 100% acceptance rate are authorized for international shipment.
A modern manufacturing facility dedicated to engineering quality and global service.
Located in the Hangzhou Bay New Zone, SILL BEARING FACTORY has direct transit access to Shanghai Port and Ningbo Port, the two largest ports in China. Quick access to regional airports allows for fast international shipping and cargo transit.
We focus on the design, production, and analysis of deep groove ball bearings (ranging from ￠4mm to ￠120mm), tapered roller bearings, and custom bearing assemblies. Using quality raw materials like GCr15 steel, we control every manufacturing stage from start to finish.
To scale our production capabilities, we are currently constructing our new facility, Anhui TOPB IMP. & EXP. Co., Ltd. Once operational, it will increase our annual export capacity by $20 million, allowing us to support larger distribution contracts worldwide.
Through our brands, SILL and NETB, and our custom OEM services, we supply parts to manufacturers in the US, Brazil, Switzerland, UAE, Turkey, Pakistan, and Egypt.
How we adapt to changing industrial requirements, sustainability targets, and manufacturing automation.
To support electric vehicle drivetrains and high-RPM spindles, we study dynamic cage behavior and internal geometries. This research helps prevent cage flutter and lowers vibration at elevated speeds.
Our production lines integrate visual inspection cameras using AI algorithms. This system analyzes raceway micro-surfaces for small imperfections, ensuring consistent surface finishes before assembly.
We collaborate with lubrication manufacturers to supply bearings pre-filled with biodegradable, wide-temperature grease. These lubricants maintain viscosity from -40°C to 180°C without oil separation.
Common questions from procurement specialists and engineers regarding materials, seals, and application limits.
GCr15 steel contains approximately 1% carbon and 1.5% chromium. This composition, combined with vacuum degasification and precision heat treatment, yields high hardness, wear resistance, and high contact fatigue strength. It prevents early spalling under repeated dynamic loads.
ZZ shields use non-contact steel plates that allow higher speed limits but cannot prevent fine dust or water ingress. The 2RS seal utilizes contact synthetic rubber lips that press against the inner ring shoulder. This design seals the bearing against contaminants and moisture, though it introduces slightly more friction and limits top speeds compared to shielded configurations.
Yes, we offer radial internal clearances (CN, C2, C3, and C4) to match your system. For applications with high thermal expansion, such as high-temperature electric motors, we recommend C3 or C4 clearances to prevent internal binding.
The bearing lifespan depends on operating loads, speed, temperature, and environment. We design our 6007 2RS bearings to achieve an L10 rating life exceeding 20,000 operational hours under normal load and speed limits, provided the seals remain intact.
All bearings receive an anti-rust coating, are individually sealed in polyethylene barrier film, and are packed into moisture-resistant cartons. For ocean freight, cartons are secured on export-grade plastic pallets wrapped in heavy-duty shrink film.
