The MGS® Speed Reducer Difference The KSS Series (inset box below) features an IP69K certified 304 stainless steel housing ideal for frequent pressure cleaning operations typical in the food industry and elsewhere. K, KL, C and F Series are optionally available with 316 stainless steel epoxy coating for IP69K certified protection (K, F and C Series shown left to right). Coatings K KL C F These speed reducers are available with 1 day turnaround on a choice of application-specific coatings: Food Duty • Primer • Industrial 316 Stainless Steel Epoxy • Silver Bullet Anti-Microbial® Epoxy (Silver Bullet AM® is a registered trademark of Burke Industrial Coating) Corrosion Resistant Duty • Primer • Industrial 316 Stainless Steel Epoxy Corrosion Resistant KSS K KL C F These units have several features and options for no maintenance operation in harsh washdown, wet, or dry environments. • Maintenance free design: lifetime lubrication and double output seals (where possible) • Stainless output bushing, shaft, or bore • 3 year standard warranty • Multilayer Industrial 316 stainless steel epoxy coating IP69K Certified Speed Reducers: The Ultimate Solution for Extreme Duty High-Pressure Wash Downs! IP69K Certified MGS Speed Reducers are sealed against dust and water ingress. To prove the point, we tested all our IP69K rated products (KSS, K, C, F) with an absolute worst case situation to make sure they can handle your washdown needs — spraying the gear reducer with 176° water at 1,450 PSI from a distance of just 10-15 cm from the reducer. None of the STOBER units were damaged and continued to run both during and after the test. 90° 60° Spray from 10-15 cm @ 1450 PSI (100 Bar) 30° • Finish is USDA accepted for food processing and handling; heat cured; IP69K sprayed at 1,450 PSI (100 bar) • Lubricated for life with Mobil SHC CIBUS 220 for food duty, or Mobil 600XP220 for beverage duty or standard duty applications • Totally enclosed – no breather to allow contaminates in or oil out and double output seals (dual lip outer seal and a single lip inner seal) • The high quality helical gearing (and spiral bevel gearing in the “K” Series) is case hardened to 58-62 Rockwell C and precision finished for low noise and long service life. With an efficiency of 97%, these reliable drives provide cost savings in energy and maintenance. • NEMA C-face input – with an O-ring between the motor and reducer and an easy mount maintenance free coupling • Mounts in ANY horizontal output position (dependent on size and ratio) without changing oil levels (other positions are optional or warranty specific) • ALL stainless steel hardware and stainless steel nameplate 0° 6 MGS ® Speed Reducers V.29 800.711.3588 • www.stober.com
Wobble Free Bushing Design KSS F K KL The STOBER “Wobble Free” bushing is a patented double side wobble free bushing system that mounts easily onto standard cold finished, ground, or stainless shafting. This unique design allows the unit to be mounted on the shaft from either side of the reducer by reversing the clamp side and support side bushings. The clamp side is the accessible outside bushing. The double sided bushing is not installed into the unit at assembly, but with quick, easy-to-follow instructions when the unit and bushing are mounted on the machine installation. Unique STOBER Quality and Design Features Interchangeable Support Side and Clamp Side Conveyor with Shaft Either Side Clamp Support Support Clamp Side Side Side Side • Can be supplied with output covers on one or both sides which protect the seals and also cover the rotating bushing • A variety of bushing bore sizes are provided for each reducer size. The reducer output bore can be changed any time by changing the bushing kit • The quill, all bushing parts, and hardware can be supplied stainless steel to provide corrosion resistance for wash down applications The distinct support side and a clamp side are interchangeable. The dual tapered cones are designed to overcome a wide range of tolerances normally found with standard shaft materials. No shaft key necessary. MGS Speed Reducers Outfitted with ComTrac® Adjustable Speed Drives The ComTrac is an adjustable speed traction drive that transfers power between a motor mounted drive cone and a traction ring. At rest, a spring loaded torque compensating assembly produces minimal contact pressure between the drive cone and traction ring. As the drive is started, the load compensating cams move against each other to increase pressure between the drive cone and traction ring. During operation, the load compensating cams maintain the proper amount of pressure between the drive cone and traction ring in proportion to the output load torque required. Speed changes are made with a hand wheel controlled rack and pinion that changes the relative running diameters of the drive cone and traction ring: the faster running outer diameter of the drive cone increases speed; the slower running center of the drive cone decreases output speed. Spiral Groove Hollow Bore F K KL KSS The inside diameter on our hollow bore units feature a spiral (rifle) bore design providing an anti-seize lubricating groove. This enables the MGS speed reducer to slide off freely when servicing without damage to the output shaft. With conventional smooth-surface hollow bore designs, any anti-seize lubricant applied during installation of the output shaft has no where to go except out the other end. Invariably, these designs will seize, making it necessary to cut off the output shaft when servicing. ComTrac is available with a severe duty protection package to withstand the effects of outdoor use, exposure to excessively humid or acidic environments, or spray wash downs with water or caustic fluids. 800.711.3588 • www.stober.com MGS ® Speed Reducers V.29 7
