MULTI-ROLLER LINEAR GUIDE
Mini Type MLG20 NEW
Latest Info
• Allows for smooth movement with the unique mechanism called "multi-roller". • Tested at 200 mm/s for 300,000 round trips of 100 mm (total distance 60 km). • Since there is no ball creep, it can be used together with a motor drive. • A 100 mm type rail is now available. • A short guide block is now available. The full length is shorter, allowing the travel length to increase by 13 mm. • An 8-wheel guide block is now available. The load rating has been improved while maintaining the same travel distance. Application • Medical equipment, food machine, amusement machine, analytical instruments. Remarks • Please use with stoppers. • Mounting plates cannot be attached to short or 8-wheel guide block.

Radial load
Roller
No ball creep due to roller type mechanism.
The multi-roller mechanism allows for smooth movement even with loads applied in radial or thrust directions.

Ball creep is a phenomenon where travel distances vary between outward and return paths due to a misaligned ball contact point that may occur on ball type rails because of sliding or applied force. If extra load is applied in this state, the rail may become unable to move.

Operating Dynamic Load Guidelines
• Max. Static Load = Static Rated Load × Static Safety Coefficient • Operating Dynamic Load = Max. Static Load × Dynamic Safety Coefficient
• Max. Moment = Static Rated Moment × Static Safety Coefficient • Operating Moment = Max. Moment × Static Safety Coefficient
