Based on Caged Roller LM Guide model SRG, this model has a wider rail and two rows of LM rail mounting holes to achieve high mounting strength and mounting stability. SRW is an ultra-high rigidity
Roller Guide that uses roller cages to allow low-friction, smooth motion and achieve long-term maintenance-free operation.
Since it has a wide rail and can be secured on the table using two rows of mounting bolts, the mounting strength is signifi cantly increased. In addition, since the crosswise raceway distance (L) is
large, model SRW is structurally strong against a moment load (Mc moment) in the rolling direction.
Furthermore, model SRW uses rollers that show little elastic deformation as its rolling elements, and the overall length of each roller is 1.5 times greater than the diameter, thus to increase the rigidity.
The roller cage allows rollers to form an evenly spaced line while circulating, thus preventing the rollers from skewing as the block enters an loaded area. As a result, fl uctuation of the rolling resistance
is minimized, and stable, smooth motion is achieved.
Use of the roller cage eliminates friction between rollers and enables the lubricant to be retained in grease pockets formed between
adjacent rollers. As the rollers circulate, the grease pocket serves to provide the required amount of lubricant to the contact curvature of
the spacer and the roller, thus to achieve longterm maintenance-free operation.
