The HU (heavy-duty) designation paired with the 140mm diameter puts this mount at the top of the lineup for load capacity and footprint coverage. This is the mount you reach for when installing larger rotary screw compressors with heavy frames where neither the 100mm mounts nor the standard-load 140mm DC mount provides adequate load capacity or isolation performance.\u003c\/p\u003e\n\n\u003cp\u003eSpecific load ratings, deflection specifications, and bolt patterns for the RCBM140HU were not published on castair.net at time of writing. Call us at 866-217-0063 — provide your compressor model, total weight, and base foot dimensions and we can confirm whether the RCBM140HU is the correct specification for your installation.\u003c\/p\u003e\n\n\u003ch3\u003eMount Specifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePart number:\u003c\/strong\u003e RCBM140HU\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter:\u003c\/strong\u003e 140mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConfiguration:\u003c\/strong\u003e Heavy Duty (HU)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Heavy-duty rubber bonded to steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Heavy air compressor vibration isolation — largest frames, highest loads\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLoad rating:\u003c\/strong\u003e Contact 866-217-0063 for confirmed specifications\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eRCBM Series Selection Guide\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRCBM100DC:\u003c\/strong\u003e 100mm, double-cup — lighter compressors, standard load\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRCBM100HU:\u003c\/strong\u003e 100mm, heavy-duty — heavier loads on 100mm footprint\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRCBM140DC:\u003c\/strong\u003e 140mm, double-cup — larger footprint, standard load\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRCBM140HU (this part):\u003c\/strong\u003e 140mm, heavy-duty — largest footprint, maximum load capacity\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eFor standard piston compressor installations, Castair's VP1004 flat rubber vibration pad set (4 x 4x4x1 pads) covers most installations at lower cost.
