High Precision Cross Roller Rail and Block Assembly
(Precise Crossing Roller and Carrier Guidway set) |
The Cross Roller Guide is a limited stroke linear guide that has precision rollers orthogonalized alternately. This product provides rigid yet supple linear motion and is particularly suitable for linear guidance where high rigidity and supple movement is demanded.;
|
| Structure and Characteristic: |
| Cross Rail and Block Assembly is made of two V- raceway Guide Rail, Roller Cage, Cylindrical Roller and so on, Intersect Lined cylindrical roller do reciprocating motion via grinding V-raceway surface guide rail. Can withstand various loadings to achieve high precision ,smooth and reliable linear motion. |
Small rolling friction resistance, stable performance;
Small Friction on start, with good dynamic performance;
With big Contact area, and a small amount of elastic variety, effective body movement, and easy to achieve high rigidity, high load exercise;
The structural design is flexible, easy to install; |
The Stroke Length and Roller Numbers |
Guideway length Calculation
The guideway length is not less than 1.5 times of the stroke; L>=1.51
Remarks: L: Guideway length (mm); L1: Stroke Length (mm)
Cage’s length: K<=L-L1/2
Remarks: K: Cage’s Length (mm)
Calculation of Roller Numbers: n= (K-2a)/f+1
Remarks: n: Roller Numbers (the Decimal Part is ignored)
a: End to End Distance of the cage f: Space between Rollers |
