The SW 6304-2RS/C3 is a high-performance single-row deep groove ball bearing engineered for demanding industrial applications requiring reliability and extended service life. Featuring precise dimensions (20mm bore, 52mm outer diameter, 15mm width), this bearing incorporates two contact rubber seals (2RS) to effectively retain high-quality internal lubricant and prevent the ingress of dust, moisture, and fine particulates. Crucially, the internal radial clearance designation C3 ensures operational stability under conditions involving high speeds, temperature variations, or heavier interference fits, mitigating premature failure caused by thermal expansion or shaft deflection. This configuration provides optimized running precision and reduced vibrational energy transfer.
As part of the SW industrial product line, the 6304-2RS/C3 is manufactured using superior grade, heat-treated chromium steel (52100 standard), guaranteeing exceptional hardness and resistance to fatigue and static loads. This pre-lubricated, sealed design simplifies maintenance protocols, making it an ideal choice for critical equipment such as electric motors, precision gearboxes, pumps, and robust conveying systems. Selecting the SW 6304-2RS/C3 translates directly into lower overall operating costs and enhanced uptime due to the bearing's proven ability to perform consistently in harsh operational environments.
