The step up from the 100mm RCBM100DC to the 140mm RCBM140DC gives you a larger bearing surface area under each compressor foot — useful for heavier compressor frames where you need to distribute the load over a larger contact zone, or for installations on softer flooring where point load matters. Both the DC and the 140mm designation together put this mount in the mid-tier of the RCBM series: larger footprint than the 100mm models, standard load rating compared to the HU heavy-duty versions.\u003c\/p\u003e\n\n\u003cp\u003eSpecific load ratings and bolt patterns for the RCBM140DC were not published on castair.net at time of writing.

It also provides better load distribution on installations where the concrete or floor surface condition is not ideal. If your compressor is 15 HP or larger (rotary screw models over 750 lbs), the 140mm footprint is worth considering over the 100mm series for the increased stability.\u003c\/p\u003e\n\n\u003ch3\u003eWhy Proper Vibration Isolation Matters\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContinuous service:\u003c\/strong\u003e Rotary screw compressors run continuously — vibration mounts must handle sustained compressive and shear loads without degrading\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePipe safety:\u003c\/strong\u003e Cup-style mounts allow a small amount of movement — always connect the compressor discharge to fixed shop piping with a metal flex hose to prevent pipe fatigue cracking\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNoise control:\u003c\/strong\u003e Larger 140mm mounts with adequate rubber mass provide meaningful attenuation of low-frequency vibration that flat pads may not fully address on larger machines\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFloor protection:\u003c\/strong\u003e Distributing compressor weight over a larger rubber contact area reduces PSI on the floor surface and reduces concrete cracking risk over years of continuous operation\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat Is in the Box\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1x Castair RCBM140DC rubber cushion base mount, 140mm double-cup configuration\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhy Buy From Air Compressor Factory Direct?\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCastair authorized:\u003c\/strong\u003e OEM mounts matched to Castair compressor installations\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFree shipping\u003c\/strong\u003e on qualifying orders\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFree tech support:\u003c\/strong\u003e 866-217-0063 — sizing guidance on 100mm vs. 140mm and DC vs. HU\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFull accessory lineup:\u003c\/strong\u003e Flex hose, ball valves, PM kits, and all Castair installation accessories\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eCall 866-217-0063 for quick answers and help!\u003c\/strong\u003e\u003c\/p\u003e","brand":"Cast Air","offers":[{"title":"Default Title","offer_id":53342589026517,"sku":"RCBM140DC","price":78.1,"currency_code":"USD","in_stock":true}],"url":"https:\/\/aircompressorfactorydirect.com\/products\/castair-rubber-cushion-base-mount-140mm-double-cup-rcbm140dc","provider":"Air Compressor Factory Direct","version":"1.0","type":"link"}
