Lubricating Sealed Linear Bearings And Motion Guideways is heavy load linear guide way designed by circular-arc groove and structure optimization are higher over 30% load capacity and rigidity than other similar ball type linear guideway.It features the same load in four directions (up/down/right/left) and self-aligning to absorb installation-error capability.
Lubricating linear bearings are essential components in various mechanical systems, designed to reduce friction, minimize wear, and enhance the overall performance and longevity of the equipment. Lubricating linear bearings and linear motion rail guide are widely used in industries such as food packaging machinery, printing machinery, and textile equipment. Effective lubrication is crucial for the optimal performance and longevity of linear bearing guides, as it helps prevent direct contact between the linear motion rail guide and the rolling elements, reducing friction and wear.
Specification
Anti friction linear motion guideways and sealed linear bearings are linear bearing guides and linear motion rail guide system that combines a lubricating system with a sealed design, specifically designed to reduce friction and improve the smoothness and life of equipment. Anti friction linear motion guideways and sealed linear bearings are widely used in industrial automation, CNC machine tools, precision instruments and other equipment to provide efficient linear motion solutions.
1.High positioning accuracy, high repeatability
The lubricating linear bearings is a design of rolling motion with a low friction coeffi cient, and the difference between dynamic and static friction is very small. Therefore, the stick-slip will not occur when submicron feeding is making.
2.Low frictional resistance, high precision maintained for long period
The frictional resistance of a sealed linear bearings is only 1/20th to 1/40th of that in a slide guide. With linear bearing guides, anti friction linear motion guideways, a well lubrication can be easily achieved by supplying grease through the grease nipple on carriage or utilizing a centralized oil pumping system, thus the frictional resistance is decreased and the accuracy could be maintained for long period.
3. Anti friction linear motion guideways are suitable for high speed operation
Due to the characteristic of low frictional resistance, the required driving force is much lower than in other systems, thus the power consumption is small. Moreover, the temperature rising effect is small even under high speed operation.
4.Easy installation with interchangeability
Compared with the high-skill required scrapping process of conventional slide guide, the sealed linear bearings and linear bearing guides can offer high precision even if the mounting surface is machined by milling or grinding. Moreover the interchangeability of linear bearing guides and linear motion rail guide give a convenience for installation and future maintenance.

Load capacity is determined by dynamic (C) and static (C₀) load ratings. For example: A 6205 deep groove ball bearing has a dynamic load rating of 14 kN, suitable for small motors. For heavy loads, choose tapered roller bearings (e.g., 32208 with C=90 kN). Recommendation: Share your equipment’s load analysis for optimal bearing selection.
Materials: Stainless steel (440C/316) or coatings (nickel plating, DLC). Seals: Double rubber seals (2RS) or PTFE seals. Example: Seawater pumps often use 316 stainless steel bearings with lifelong grease.
Speed limits depend on bearing type and lubrication: Standard 608ZZ ball bearings: ~18,000 rpm. Hybrid ceramic bearings (Si3N4 balls): 30–50% higher speeds. Solution: For high-speed applications, opt for oil lubrication or low-friction design.
Theoretical lifespan: Based on load calculations (see Q1). Real-world factors: Lubrication intervals (e.g., grease replenishment every 100km). Mounting surface flatness (≤0.01mm/m required). Tool: Free lifespan calculation software available.
Must-check: Slider hole spacing (e.g., 45mm×45mm). Rail width (15/20/25mm, etc.). Slider height (impacts machine space). Pro tip: Old slider model numbers are often engraved on the side.
