Industrial machinery operators know the cost of unexpected downtime—hours lost to bearing failures, production delays, and emergency repairs. Many struggle with inconsistent quality from low-cost suppliers, where bearings fail prematurely under radial loads or high speeds. Sourcing reliable 20x52x15mm bearings with flexible MOQ and fast delivery often feels like a challenge, especially when balancing precision needs with budget constraints.
Our Deep Groove Ball Bearing 6304R addresses these pain points with precision engineering and customer-centric service. Available in P0-P4 precision grades and ZZ/2RS seal options, this 20x52x15mm bearing delivers consistent performance in machine tools, conveyors, and electric motors. Backed by our ISO9001-certified manufacturing process and 12-month global warranty, we ensure each unit meets strict quality standards—from raw material inspection to final performance testing. With 1pc MOQ for standard items and 3-5 day sample lead times, we support both emergency repairs and long-term production planning.
Designed as a radial bearing with a 0° contact angle, the 6304R excels in applications requiring high rotational speed and steady radial load handling. Its single-row, unseparated construction ensures stability in continuous operation, while ZZ metal seals or 2RS rubber seals protect against dust and moisture—critical for harsh industrial settings. Whether used in printing machinery requiring low vibration (Z2-Z4 noise grades) or agricultural equipment needing耐磨 performance, this bearing maintains efficiency across temperature variations and heavy-duty cycles.
The 6304R’s performance is defined by key technical features that directly impact your equipment’s longevity. Precision ratings from P0 (general industrial use) to P4 (high-precision applications like CNC spindles) control runout and dimensional accuracy, reducing vibration and noise. Vibration grades Z1V1 to Z3V3 further minimize operational sound, a must for noise-sensitive environments. Constructed from high-quality bearing steel, it balances hardness and toughness to withstand dynamic loads, while grease or oil lubrication options allow customization for specific speed and temperature requirements. These attributes combine to extend bearing life and reduce maintenance intervals.
Choosing low-quality bearings may save upfront costs, but the hidden expenses add up quickly. Counterfeit or substandard 6304R bearings often fail within months, leading to unplanned downtime, replacement labor, and potential damage to connected components. In contrast, our bearings—manufactured with full R&D support and QC lab testing—deliver predictable performance, lowering total cost of ownership. We stand behind every unit with defect replacement and free technical guidance, ensuring you avoid the risks of premature failure in critical machinery.
