1 GEM 4 N Synthetic high-performance gear and multipurpoe oil Your benefit at a glance High cuffing protection Excellent wear protection for gear and rolling bearing Good hear tability for reliable lubricant film formation High micropitting reitance Excellent ageing and oxidation reitance Wide ervice temperature range due to good vicoity-temperature behaviour Low foaming tendency Energy aving due to optimied friction behaviour Good elatomer compatibility Approval by numerou gear OEM Your requirement our olution GEM 4 N i a ynthetic high-performance gear and multipurpoe oil baed on polyalphaolefin atifying the growing requirement and increaing power denity of modern gear. GEM 4 N include KlüberComp Lube Technology*, i.e. it i baed on epecially high-grade raw material and advanced additive, enabling maximum performance in the lubrication of all gear component. GEM 4 N clearly exceed CLP requirement according to DIN Correponding gear can be witched to GEM 4 N without prior conultation with the gear manufacturer provided the general application note are oberved. Klüberoil GEM 4 N offer high cuffing load capacity. Gear are ufficiently protected againt cuffing even at extremely high peak load, vibration or ocillation. The excellent wear protection of both gear and rolling bearing enure that the ervice life calculated for the lubricated component i achieved, leading to lower maintenance and repair cot. The oil' high micropitting reitance of GFT 10 according to FVA 54/7 offer ufficient protection to gear that are ubject to high load and would normally be uceptible to thi type of damage. GEM 4 N offer a much longer ervice life than mineral oil due to the excellent ageing and oxidation reitance of the elected raw material; thu ervice interval can be extended and maintenance cot reduced. The product' low foaming tendency and anti-corroive propertie enable problem-free gear operation. Freudenberg eal made of 72 NBR 902, 75 FKM 585, 75 FKM and 75 FKM are reitant to GEM 4 N. Leakage and oil contamination are prevented. The excellent vicoity-temperature behaviour upport the formation of a ufficient lubricant film acro a wide ervice temperature range, even at elevated and high temperature. Therefore, a ingle vicoity grade can cover both low and high temperature in many application. The optimied friction behaviour enabled by the carefully elected bae oil reduce power lo and improve gear efficiency. GEM 4 N i approved by Boch Rexroth, SEW Eurodrive, Getriebebau Nord, Lenze, Moventa, Bonfiglioli, Stöber Antriebtechnik, ZAE Antriebyteme, David Brown, FLSmidth MAAG Gear, ACCIONA ENERGY, etc. By uing GEM 4 N you can benefit from a number of advantage that will help you ave cot eaily and efficiently. We look forward to hearing from you. * For further information, pleae ee our flyer: KlüberComp Lube Technology Gear oil meeting the highet requirement Application GEM 4 N wa pecially developed for the lubrication of pur, bevel, hypoid and planetary gear that are ubject to high load. Such gear are frequently ued in the wind, teel, mining and ugar indutrie. It i alo ued for the lubrication of tandard worm gear a defined in DIN GEM 4 N can alo be ued for the lubrication of plain and rolling bearing, all kind of toothed coupling, chain, guideway, joint, pindle and pump, epecially in application where the equipment i expoed to elevated temperature or pronounced temperature fluctuation.

2 GEM 4 N Synthetic high-performance gear and multipurpoe oil Application note GEM 4 N can be applied by mean of immerion, immerion circulation or injection. The ue of drip-feed oiler, bruhe, oil can or uitable automatic lubricating ytem i alo poible. When uing automatic lubricating ytem, pleae note the manufacturer' intruction regarding the maximum permiible vicoity. The low-vicoity varietie are alo ued for oil mit lubrication. GEM 4 N i micible with mineral oil. However, for the GEM 4 N oil to deliver it full performance, any reidue of a previouly ued mineral oil hould not exceed 5 % in quantity. For ue at permanent temperature of 80 C max., eal made of NBR may be ued. For higher temperature, eal made of FKM hould be choen. It hould be noted that elatomer from one or everal manufacturer can behave differently; therefore tet hould be performed. For checking the contact pattern during running-in, the inpection paint Klübertop P Spray (Art. No ) can be ued. Vicoity election When determining the oil vicoity for gear lubrication, the gear manufacturer' intruction take priority. Only for application where manufacturer' intruction are not available, the uitable vicoity can be determined a laid down in the workheet "Hint for Practice - election of oil vicoity for gear". To determine the correct oil vicoity for bearing, pleae oberve the bearing manufacturer' intruction. Due to the better vicoity-temperature behaviour of GEM 4 compared to mineral oil, the actual vicoity of GEM 4 N during operation differ and can be determined by mean of the encloed diagram.
