PMI’s linear roller guides offer the highest rigidity and load capacity compared to other guides of the same size. Due to the linear contact between the rollers and the raceways, the roller guides provide less deformation under the same loads.

The load stiffness characteristics predispose the roller guides to be used in applications where very high loads and high impact resistance are common, e.g. in cranes, heavy machine tools and rolling mills. Thanks to the 45° angle of the rollers, the guide with roller rail can absorb identical forces in all directions.

Performance of PMI’s guides – MSR and SMR series:

• mechanical sizes: from 25 to 65
• dynamic load capacity: from 27,4 kN to 277 kN
• static moments: from 0.63k Nm to 117.87 kNm.

Thanks to the sophisticated design they provide:

• low friction (the difference between dynamic and static friction has been reduced to a minimum)
• reduced friction ensures high precision of movement for longer periods of time
• the PMI’s guide’s friction resistance is only 2.5% to 5% of the guide’s resistance
• efficient lubrication system that extends service life and flexibility.

The low friction resistance obtained in the linear guides offered by Archimedes implies a reduction of power needed for proper functioning. As a result, labour and service costs are reduced.

The well prepared design of PMI’s guides is also a modular, convenient installation. It increases safety and reduces line maintenance costs.

Intelligently designed and precise PMI’s linear guides are suitable for use wherever other products do not meet expectations.
