What are different types of linear blocks?

Linear guide can be divided into three kinds: wheel linear guide, cylindrical linear guide and ball linear guide, which are used to support and guide the moving parts to do reciprocating linear motion in the given direction. So today we focus on understanding the classification of the following ball linear guide.

 

Linear block is an important part of the ball linear guide, linear blocks can even be purchased separately, so what are the common categories of ball linear guide? We will also classify them from three aspects.

1. Classification according to the rolling parts of the linear blocks
2. Classification according to the width size of linear blocks
3. Classification according to the appearance of the linear blocks

 

• 1.Classification according to the rolling parts of LIMON linear blocks:

 (1) All steel ball type linear guide: LIMON H and E series.

①LIMON H series-Heavy load ball type linear guide

1. Series Introduction: H series linear guides are designed with load capacity and rigidity higher than other similar products with circular-arc groove and structure optimization. It features equal load ratings in the radial, reverse radial and lateral directions, and self-aligning to absorb installation-error. Thus, LIMON H series linear guide can achieve a long life with high speed, high accuracy and smooth linear motion.
2. Construction of H series: 

②LIMON E series-Low profile ball type linear guide

1. Series Introduction: The design of the E series offers a low profile, high load capacity, and high rigidity. It also features an equal load rating in all four directions and self-aligning capability to absorb installation-error, allowing for higher accuracies. Additionally, the lower assembly height and the shorter length make the E series more suitable for high-speed, automation machines and applications where space is limited. The retainer is designed to hold the balls in the block even when it is removed from the rail.
2. Construction of E series:

 

(2) ball retainer type linear guide: LIMON QH and QE series.

①LIMON QH series-Quiet linear guide & QE series-Low profile linear guide

1. Series introduction: The development of LIMON-QH linear guideway is based on a four-row circular-arc contact. The LIMON-QH series linear guideway with SynchMotion^TM Technology offers smooth movement, superior lubrication, quieter operation and longer running life. Therefore the LIMON-QH linear guideway has broad industrial applicability. In the high-tech industry where high speed, low noise, and reduced dust generation is required, the LIMON-QH series is interchangeable with the LIMON-H series.
2. Construction of QH series & QE series:

 

（3）roller retainer type linear guide: LIMON R series.

①LIMON R series-High rigidity roller type linear guide

1. Series introduction: The new R series from LIMON features a roller as the rolling element instead of steel balls. The roller series offers super high rigidity and very high load capacities. The R series is designed with a 45-degree angle of contact. Elastic deformation of the linear contact surface, during load, is greatly reduced thereby offering greater rigidity and higher load capacities in all 4 load directions.The R series linear guideway offers high performance for high-precision manufacturing and achieving longer service life.
2. Construction of R series:

 

• 2.Classification according to the width size of linear blocks

1. Size 15 Linear blocks
2. Size 20 Linear blocks 
3. Size 25 Linear blocks 
4. Size 30 Linear blocks 
5. Size 35 Linear blocks 
6. Size 45 Linear blocks 
7. Size 55 Linear blocks 
8. Size 65 Linear blocks

 

• 3.Classification according to the appearance of the linear blocks

In short, the linear blocks, as a mobile element on the linear guide, can usually be divided into the above two types of flange type and square linear blocks but different types of linear blocks can also be subdivided according to the load capacity, precision and other parameters.
