Structure and Features
Balls roll in four rows of raceways precision-ground on an LM rail and an LM block, and endplatesincorporated in the LM block allow the balls to circulate. The raceways are cut into deep grooves thathave a radius closer to that of the balls than in the conventional design, using special equipment andan extremely precise cutting technique. This design allows high rigidity, high vibration/impact resis-tance and high damping capacity, all of which are required for machine tools, thus making thesemodels capable of bearing ultra-heavy loads.* Due to the extremely high rigidity of the LM guides used in models NR/NRS, the construction does not easily absorb the
effects of mounting surface misalignment and installation errors. Where such effects arise, there is a risk of reduced operat-ing life and/or malfunction. Contact THK when considering the use of these products.
[Improved Damping Capacity]While the machine tool (equipped with NR or NRS) is not cutting a workpiece during operation, theLM Guide travels normally and smoothly. While the machine tool is cutting the workpiece, the cuttingforce is applied to the LM Guide to increase and the contact area between the balls and the raceway,allowing an appropriate mixture of rolling and sliding motions to be achieved. Accordingly, the frictionresistance is increased and the damping capacity is improved.Since the absolute slip during the rolling and sliding motion is insignificant, it causes little wear anddoes not affect the service life.
[Highly Rational LM Guide]The excessively large differential slip occurring in a Gothic-arch groove does not happen with thesemodels. They smoothly travel and achieve high positioning accuracy during fast feeding. During thecutting operation, appropriate slip occurs according to the cutting load, the rolling resistance isincreased and the damping capacity is increased. Thus, models NR and NRS are highly rational LMGuides.
[High Rigidity]To increase the rigidity of the LM block and the LM rail, which may deteriorate the overall rigidity ofthe LM Guide in the reverse radial and lateral directions, THK made full use of FEM to achieve opti-mal design within the limited dimensional range.THK provides two identically sized models with different characteristics, namely the radial model NRand four-way equal-load model NRS, users can select the model that best suits their specifications.
[Ultra-heavy Load]Since the curvature of the raceway is approximated to the ball diameter, the ball contact area undera load is increased and the LM Guide is capable of receiving an ultra-heavy load.
Types and Features
Models NR-R/NRS-R Specification Table⇒B1-100/B1-102With this type, the LM block has a smaller width(W) and tapped holes. Used in places where thespace for table width is limited.
Models NR-A/NRS-A Specification Table⇒B1-104/B1-106The flange of its LM block has tapped holes.
Models NR-B/NRS-B Specification Table⇒B1-108/B1-110The flange of the LM block has through holes.Used in places where the table cannot havethrough holes for mounting bolts.
Models NR-LR/NRS-LR Specification Table⇒B1-100/B1-102The LM block has the same cross-sectionalshape as models NR-R/NRS-R, but has a lon-ger overall LM block length (L) and a greaterrated load.
Models NR-LA/NRS-LA Specification Table⇒B1-104/B1-106The LM block has the same cross-sectionalshape as models NR-A/NRS-A, but has a longeroverall LM block length (L) and a greater ratedload.
Models NR-LB/NRS-LB Specification Table⇒B1-108/B1-110The LM block has the same cross-sectionalshape as models NR-B/NRS-B, but has a longeroverall LM block length (L) and a greater ratedload.
Characteristics of Models NR and NRS
[Increased Rigidity in Major Load Directions]The structure with a contact angle of 90° used inmodel NR differs from that with a 45° contactangle also in rigidity. Under the same radial loadP, the displacement in the radial direction withmodel NR having a contact angle of 90° is 44%less than the 45° .
Fig.2 shows the difference in radial load and dis-placement. Accordingly, where high rigidity inthe radial direction is required, model NR ismore advantageous.
[Increased Rigidity in the Lateral and Reverse-radial Directions]Since with LM Guide model NR, the distance"H" between the rail bottom and the lower-groove balls (balls receiving lateral loads) isshort, the ratio between the rail width "W" andthe distance "H" is small, and the distance "T"between the LM rail mounting bolt seat and theLM rail bottom is short. Accordingly, the defor-mation of the LM rail under a lateral load is mini-mal, and the rigidity in the lateral directions isincreased.Since the dimension "B" of the LM block is shortand the thickness "A" is large, the lateral exten-sion of the LM block under a reverse radial orlateral load is minimized. This structure allowsthe rigidity in the reverse radial direction to beincreased.In comparison to the old model with the samemodel number, the ball diameter of NR issmaller and the number of effective balls isapproximately 1.3 times greater, thus increasingthe static rigidity.

[Comparison of Contact Surface and Internal Stress between Different Contact Structures]As shown in Fig.4, the contact area and the internal stress of a ball greatly vary depending on theshape of contact surface.With the conventional roller guide, the effective length is shorter than the apparent value due to theretention of the rollers. Additionally, the change of stress distribution in the contact section caused bya mounting error significantly affects the differential slip.

Rated Loads in All Directions
Models NR/NRS are capable of receiving loadsin all four directions: radial, reverse radial andlateral directions.The basic load ratings of model NR are indi-cated by the values in the radial directions inFig.5, and their actual values are provided in thespecification table for NR/NRS. The values inthe reverse radial and lateral directions areobtained from table 1 below.The basic load ratings of model NRS are equalin all the four directions (radial, reverse radialand lateral directions), and their actual valuesare provided in the specification table for NR/NRS.
