Roller-based modular linear system

The complete modular linear system MODULARACE isdesigned around double row precision ball-bearing rollers, with high radial and axial load capacities, and raceways with a protruding truncated cone-shape. The complete system has hardened and honed raceways and a surface treatment for high resistance to wear and corrosion. Thanks to the many combination possibilities, a wide range of linear rails have been developed within MODULARACE, to satisfy the demand for strong reliable linear systems, for medium precision applications and general automation. Two rail designs and different size rails are available: TheMR-rail with internal raceways (RAILRACE) and the FXR-rail with external raceways (FLEXRACE). They both have the same protruding truncated cone raceway shape, but theFLEXRACE has multi direction raceways.The rails are all completely surface hardened. The innovative hardening treatment also offers a standard high wear andcorrosion protection, assuring long life for the whole system.

MRLMRS

The C-shaped cross section offerswell protected internal raceways and provides compact overall dimensions. The MR-rails are offered in 3 sizes and all with 2 different fixhole systems for the rail installation: MRL-rails for cylindrical TORX head screws for which the special screws are supplied, see below screw dimensions, or MRS-rails for standard countersunk screw heads.The screw pitch for all MR-rails is80mm and a 40mm pitch for first and last fixing hole.

Tolerance forfirst-last hole

Includes the following systems:

MRS18 +/- 0,25 MRS28 +/- 0,30MRS43 +/- 0,40MRL18 +/- 0,50 MRL28 +/- 0,60MRL43 +/- 0,80

•The MRS-rails with countersunk mountingholes, offers quick rail assembling, as therail aligns itself to the linearity of the holes.Very useful when holes are decent drilled or installation in profiles with T-slots.•The MRL-rails with cylindricalmounting holes, allow the rails to be precisely aligned to a lateralreference, and are useful when theholes are not so precisely made. MRL-rails should not be used for T-slot profiles
