SMSR Grip-Loc Bushing for size D, bore diameter 40mm
Metric SMSR Range
Shaft mounted drives remove the need for couplings, mounting plinths and have infinitely variable ratios due to the belt drive. They are also incredibly simple to fit and can be mounted in any position as no motor base is required.
• Grip-Loc hubs now avaliable for simple installation and removal
• Includes complete torque arm assembly
• Interchangeable with most other manufacturers
• Production line manufacturing guarantees tolerances and consistent quality.
• Gears produced on German manufactured hobbing centres to achieve the highest quality helical gear components.
• Pinions; 8620 steel
• Gears; 20MnCr5 steel
• All gears are ground
• Final heat treatment includes gas carburising to a depth of 1mm, then grinding to DIN class 6.
• Castings crack tested
• All units test run prior to final quality control checks
• Full traceability guaranteed with unique Challenge serial number.
• Backstops also available to prevent reversing
• Drive ratios exceed 150:1 with a belt drive
• Double lipped oil seals used throughout
• Standard ball and cylindrical roller bearings used - in stock around the world
Metric SMSR Range
Shaft Mounted Speed Reducers offer a flexible speed reduction solution due to their combination with belt drives, offering ratios in excess of 150:1. Challenge SMSR torque arms offer not only easy installation, but also allow the belt to be kept tensioned without having to move the motor or other prime mover. The SMSR’s themselves are offered in 3 ratios; 5:1, 13:1 and 20:1 which can accommodate driven shafts ranging from 25mm up to 150mm diameter. Maintenance is also an important consideration with our SMSR’s. Not only do we use standard bearings which are easily available globally, but Challenge can also supply all of the components that are used within the unit.
Simple Construction - Main Components
• Output hub, gear, seals and bearings.
• Intermediate shaft, gears, seals and bearings.
• Input shaft, gear, seals and bearings.
Please see our catalogue for maintenance part product codes.
Bearings used are standard and available around the world.
Ease of Lubrication
There are four plugs on SMSR’s to cover lubrication in all available mounting positions:-
Depending on which of the 4 mounting positions is used, a different plug can perform a different role i.e. a filler in position 1 becomes the drain in position 2.
All SMSR’s are available with backstops, although it is not advsied to use a backstop on the 5:1 ratio SMSR's.
Backstops are fitted behind the cover plate on the opposite end of the input shaft.
Reducing Bush Locking System
The Challenge reducing bush locking system allows multiple driven shaft sizes to be used with a single model of SMSR. The reducing bush locking system is simple to fit but requires keyways so many customers have now switch to the Grip-Loc system.
Challenge Grip-Loc Locking System
• Has sufficient torque transmitting ability to avoid the need for conventional shaft keys.
• Reversible assembly.
• Obviates problems caused by the usual operating environment and atmospheric conditions.
• By virtue of the design, Grip-Loc prevents the onset of fretting corrosion, which often causes problems with more conventional mounting systems.
• Much simpler to install and remove than keyed assemblies.
• Fits standard shafts with h11 tolerances.
