G1 and 3F Alert 7 1 mm s 0 39 ips Danger 11 0 mm s 0 61 ips How to choose the correct Enveloped Acceleration Classification for your machinery The Enveloped Acceleration Classification CL1 CL2 or CL3 you specify determines the instrument s bearing vibration alarm levels Therefore the Enveloped Acceleration Classification that best describes the general size and speed of the bearings being measured should be selected Options are CL1 Bearings with a bearing bore diameter be tween 200 and 500 mm 7 9 and 19 7 in and a shaft speed below 500 r min Alert 1 gE Danger 2 gE CL2 default Bearings with a bearing bore diameter between 50 and 300 mm 2 0 and 11 8 in and a shaft speed between 500 and 1 800 r min Alert 2 gE Danger 4 gE CL3 Bearings with a bearing bore diameter be tween 20 and 150 mm 0 8 and 5 9 in and a shaft speed from 1 800 to 3 600 r min Alert 4 gE Danger 10 gE Note As with all commonly published severity guidelines the above provides target thresholds for new refurbished and recently maintained equipment In addition if both lower limits of the guideline are used for example in CL2 a 50 mm bearing bore diameter at 500 r min the applicable alarm values maybe lower Note that bearing bore diameter is equal to shaft height Expanding your capabilities with SKF Machine Condition Advisor compatible accessories Extension sensor kit Model CMAC 105 K
