Introduction of the linear bearing?
Linear motion bearings have the characterized of smooth movement,low friction,high rigidity and long life span,economical and easy to maintain or replace.
our top mission is 100% quality control and 100% customer satisfied. we are responsible to assist our customer to be competitive and advantaged in the market.
Motorized linear slides such as machine slides, XY tables, roller tables and some dovetail slides are bearings moved by drive mechanisms. Not all linear slides are motorized, and non-motorized dovetail slides, ball bearing slides and roller slides provide low-friction linear movement for equipment powered by inertia or by hand. All linear slides provide linear motion based on bearings, whether they are ball bearings, dovetail bearings or linear roller bearings. XY Tables, linear stages, machine slides and other advanced slides use linear motion bearings to provide movement along both X and Y multiple axis.
What's the advantage of the linear bearing?
1. Maintenance-free,Drying working,noiseless;
2. Suitable for long-time running in dusty environments;
3. Corrosion resistance;Cleaning with disinfectant lotion;
4. Inclined groove designation provides better protection to the shaft;
5. Narrowed groove improves the load capacity;
6. Easy installation and replacement;
7. Suitable for lightweight design.
Application:
Linear bearing is widely used in electronic equipment, tensile testing machine and digital 3 d coordinate measuring equipment such as precision equipment, and multi-axis machine tools, automatic punching machine, tool grinding machine, gas cutting machine, printer, card sorting machine, industrial machinery, such as food packages installed the sliding parts.
(1) Motion bearings
Linear motion bearings is a linear motion system at low cost production, for unlimited travel used with cylindrical shaft. Because point contact ball bearing with shaft, so using the load is small. Steel ball with minimal friction spinning, which can obtain high precision of smooth movement. Linear motion bearings metric and inch series: standard (LM/LME/LMB.. UU), gather (LM/LME.. UUAJ) and open (LM/LME.. UUOP); The stretched (LM/LME.. LUU); Flange type (LMF LMK/LMH.. UU, LMEF/LMEK. UU), flange (xl (LMF/LMK/LMH.. LUU, LMEF/LMEK. LUU) among assembly flange type (LMFC LMKC), with leading end flange (LMF - E/LMK - E), simple, OB since embellish, KH LMC/LMG open rack straight line slide block, etc.
(2) Sliding bearing
In the rolling bearing, bearing ring by rolling unit (roller), separately in the sliding guide system, movable part in static sliding guide rail or shaft. According to the type of rail system, sliding layer on the portable or rigid good components. Embedded lubricating oil lubricating sliding layer to to achieve. INA linear sliding bearing is endless stroke length linear bearings. The linear guidance system may be a miniature sliding guide system, Permaglide linear sliding bearings and Permaglide linear sliding shaft bearing unit and tablet guidance system. Miniature sliding guide system includes a guide/slider sliding layer system and no maintenance, Permaglide linear sliding bearing unit is the installation of a low maintenance requirements in light metal circles Permaglide bushing. Tablet guidance system is low maintenance requirements of sliding layer on the guide rail guiding system.
How to Maintenance the linear bearing?
Clean the bearing will be removed check, use methods such as taking pictures first recorded appearance. In addition, to confess the residual amount of lubricant and lubricant sampling, and then clean the bearing. Examination and distinguish to distinguish can remove the bearings from scratch using, check on the accuracy for the standard, rotating accuracy, internal clearance and collaboration, raceway surface, insist on frame and seal rings etc. About the inspection effect that can be used by bearing or known bearing. Sentenced to standard according to the mechanical function and importance as well as other inspection cycle, etc.
