HGH30HA Linear Guide

Description

Linear guide rails, also known as slide rails, linear guide rails, and linear slide rails, are used to support and guide shifting parts and perform reciprocating linear motion in a given direction. Unlike oil-free bushings, there is no intermediate medium between the moving element and the constant element, but rolling steel balls.

Under the same volume of motion components, it has higher rated load and linear motion accuracy than linear bearings. At the same time, it can bear a sure torque load, and can obtain high-precision linear motion under high load conditions.

Product Description

linear slide rail is a kind of rolling guide, it is composed of steel ball between slide block and the slide rail for the infinite scroll circulation, make the load platform can easily along the slide rail with high precision linear motion, the coefficient of friction can be decreased to 1/50 of the traditional sliding guide, make it can easily reach mu m class location accuracy.Between slide block and the slide rail making yuan at the end of the design, make the linear slide rail can be under the direction of the up and down or so and so on various load at the same time, the recycling of patent system and streamlined shape plan makes linear slide rail with extra clean and low noise.

HG series guideways can be classified into non-interchangeable and interchangeable types. The sizes are identical. The only difference between the two types is that the interchangeable type of blocks and rails can be freely exchanged, and their accuracy can reach up to p class. The model range of HG sequence incorporates the size, type, accuracy class, preload class, etc.

Product Features

(1) Self-Aligning Capability
By design, the circular-arc groove has contact points at 45 degrees. HG series can absorb most installation errors due to surface irregularities and grant easy linear motion through the elastic deformation of rolling factors and the shift of contact points. self-aligning capability, high accuracy and smooth operation can be obtained with an easy installation..

(2) Interchangeability
Because of precision dimensional control, the dimensional tolerance of HG series can be kept in a reasonable range, which means that any blocks and any rails in a specific sequence can be used together while maintaining dimensional tolerance. And a retainer is added to prevent the balls from falling out when the blocks are eliminated from the rail.

(3) High Rigidity In All Four Directions
Because of the four-row design, the HG series linear guideway has equal load ratings in the radial, reverse radial and lateral directions. furthermore, the circular-arc groove provides a wide-contact width between the balls and the groove raceway permitting giant permissible masses and high rigidity.
