1 Staless Steel Flexible Membranes Overload and nti-fly Protection ollars nti-orrosion Treatment Membrane Unit ssembly for Easeof Fittg E Fitted olts for alance Integrity F Scalloped Hubs to Maximize ore F E Product escription John rane s Metastream L Series range of membrane couplgs has been specifically designed to provide a cost effective solution for demandg dustrial applications. The couplgs are selected by their torque capacity, with the scalloped hub providg the right size for the shaft. Easy to stall Operates either direction Hubs supplied either fish mached or solid oated carbon steel hardware for corrosion protection hoice of hub configuration to suit the shaft diameter omplies with TEX 95 for use hazardous environments on Group II category 2 equipment esign Features Fit and Forget - esigned for fite life, and with correct machery alignment, often outlasts the maches it is connected to Overload Protection - Fitted with overload collars to protect the membranes the event of severe torsional overload Low Imposed Loads - esigned to optimize their torque capability, while mimizg the reaction forces due to misalignment so reducg machery vibration and maximizg bearg life Zero Matenance - No relative movg parts, and hence requires no lubrication or matenance No acklash - esigned with fitted bolts, and torsionally stiff membranes ensures that there is zero backlast, makg the couplg ideal for drives applications where constant speed without fluctuations is crucial

Lase--Lign EX Shaft lignment System is one of the toughest and most robust measurement and alignment systems available. For alignment work potentially explosive environments, equipment needs to be explosion-protected. Lase--Lign EX Shaft lignment System complies with the latest TEX standards for work such environments. alance ondition ouplg Ratg (Kw) alance improvement not generally required alancg Limits alance improvement may be required L Series Operatg Speed (thousand rpm) This couplg is designed with a high herent balance, due to the precision of the manufacturg process. It is important that all parts are carefully stored and fitted to mata this tegrity. The herent balance of the L Series meets GM standard class 8. The maximum operatg speeds listed the tables are on the basis of this GM class 8 characteristic, to provide a general guide to maximum permissible speed. If higher speeds are required contact John rane for an alternative couplg selection.
