When your CNC machine spindle fails or your automation line grinds to a halt, every hour of downtime eats into profits. Sourcing replacement deep groove ball bearings often means juggling multiple suppliers, verifying authenticity, and waiting weeks for delivery—especially for precision grades like P4 and P2. The 6704-2RS, 6804-2RS, and 6904-2RS bearings are critical components in high-speed, low-friction applications, and choosing the wrong supplier can lead to premature wear, increased vibration, and costly rework.
As an officially authorized distributor for TIMKEN, KOYO, and NTN, we guarantee 100% genuine 20x27x4mm deep groove ball bearings with full traceability. Our inventory includes P4 and P2 precision grade bearings ready for same-day dispatch, eliminating the lead time headaches that plague multi-supplier procurement. Whether you need a single bearing for emergency maintenance or bulk quantities for production lines, our one-stop procurement process streamlines ordering, technical verification, and delivery—all managed through a dedicated account manager.
These deep groove ball bearings excel in applications requiring smooth rotation, radial load capacity, and minimal friction. With a contact angle of 0° and non-aligning design, they perform reliably in high-speed spindles, precision conveyors, and servo motor assemblies where misalignment is minimal. The 2RS sealing provides effective protection against contaminants while maintaining low torque, making them ideal for clean environments like semiconductor fabs and medical device manufacturing facilities. Available in vibration classes Z1V1 to Z3V3, they meet strict noise and stability requirements for sensitive equipment.
The precision rating directly impacts your equipment’s accuracy: P4 and P2 grades ensure tighter dimensional tolerances, reducing runout in CNC spindles and improving part quality. Bearing steel construction delivers the durability needed for continuous operation, while the single-row design balances load capacity with compact dimensions—critical for space-constrained machinery. The 20mm bore diameter, 27mm outer diameter, and 4mm width make these bearings compatible with standard shafts in small to medium-sized industrial equipment. Vibration class Z3V3 options further enhance performance in high-speed applications by minimizing resonance and heat generation.
Non-genuine bearings may cost less upfront, but they often fail prematurely—costing far more in downtime, repair labor, and damaged machinery. Our ISO 9001 and DIN compliant quality control ensures every bearing undergoes rigorous testing before shipment, from material verification to dimensional accuracy checks. Unlike uncertified suppliers, we provide complete documentation, including brand authorization certificates and inspection reports, critical for compliance in aerospace and medical industries. The true cost of a bearing isn’t just its price tag; it’s the reliability of your production line and the longevity of your equipment.
Our 15+ years as a premium bearing distributor have earned us partnerships with clients in 45+ countries. We maintain sufficient ready stock of P4/P2 precision bearings for rapid delivery, with emergency shipment options for critical breakdowns. Our senior application engineering team provides free technical support, from bearing selection to working condition matching, ensuring you get the right component for your specific application. Every order includes shockproof, dustproof packaging to preserve precision during transit, and our centralized logistics process consolidates multi-brand orders to reduce coordination costs.
