We provide different linear slider bearing

Linear slider bearing is the core mechanical components of linear motion systems.Mainly used to achieve infinite stroke linear motion in conjunction with cylindrical shafts. It can be divided into standard type, flange type, open type, etc., Among which LM series (metric) and LME series (imperial) are suitable for different regional standards. Widely used in precision machine tools, textile machinery, food packaging machinery, electronic equipment, and automotive manufacturing automation assembly lines and other fields.

LM UU series linear slider bearing are standard linear motion bearings widely used in the field of industrial automation. 
1.Model analysis
Naming rules
LM: Refers to standard linear bearings
Number: represents the inner diameter of the bearing. (e.g. LM20UU has an inner diameter of 20mm)
UU: Double sealing ring design. (OP is an open type, AJ is an adjustable gap type)
Typical size
Inner diameter range: 3mm to 100mm. (common models LM3UU-LM100UU)
Standard outer diameter: 1.5-2 times the inner diameter .(such as LM20UU outer diameter of 32mm)
2、 Core Features
Structural Design
Made of bearing steel material, some models support electroplating rust prevention treatment.
Closed type UU seal can prevent dust and extend service life.

Plastic linear slider bearing are self-lubricating linear motion components based on engineering plastics.Which achieve linear guidance function through sliding friction. Compared with metal linear bearings.Its core advantages lie in lightweight, corrosion resistance, and maintenance free characteristics.
1、 Core Features
Materials and Structure
Main materials: engineering plastics such as polyamide (PA), polytetrafluoroethylene (PTFE), polyimide (PI), etc.
Friction mode: sliding friction (surface contact), in contrast to rolling friction (point contact) of metal linear bearings.
Typical design: Built in chip groove, allowing for use in dusty or liquid environments.
Performance advantages
Self lubrication: Contains solid lubricants (such as graphite, PTFE) and does not require external lubrication.
Chemical resistance: Suitable for corrosive environments such as acid and alkali, high humidity, etc.
Low noise: The noise during medium to high speed operation is significantly lower than that of metal bearings.
Electrical insulation: suitable for scenarios such as electronic devices that require protection against current conduction.
2、 Application scenarios
Food machinery: Complies with FDA standards to avoid lubricant contamination.
Medical equipment: Low maintenance requirements in clean environments.
Light industry automation: low speed and high load scenarios such as conveyor belts and packaging machines.

The RUS series linear roller slider bearing are designed specifically for high-precision linear motion systems.Are widely used in fields such as machine tools and automation equipment.
1、 Core parameters
Structural design: Using cylindrical rollers in contact with the guide surface, the load-bearing capacity is significantly higher than that of ball bearings.
2、 Performance characteristics
High rigidity: The linear contact design between the roller and the guide rail can withstand radial/axial composite loads.
Modular installation: Supports KS type slider rail system for easy integration into equipment.
Environmental adaptability: The GR3 suffix indicates standard sealing and is suitable for dusty environments.
3、 Typical applications
Numerical Control Machine Tool: Used for worktable linear guide system.
Industrial robots: robotic arm joint guide components.
Precision measuring equipment: high repeatability positioning accuracy scenarios.
