Telescopic Linear Guides is consisted of rail, block, rolling elements, retainer, recirculator, end seal etc. By using the rolling elements, such as balls or rollers between the rail and block, the sliding guide rail can achieve high precision linear motion. The telescopic linear slide is divied to flange type and square type without flange. Standard type block,Short type block. Also, telescopic linear guide is divided to high load capacity with standard block lenth and ultra high load capacity with longer block length.
Advantages of telescopic linear slides:

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.
Of course, we provide customized service, including add customers’ logo on the products, customized size of linear guide rail.
It according to the products, we usually can adjust the quantity according to customers’ request.
