SK8 Shaft Support is a 8mm shaft support that fixedly connects the screw and motor bearings. Bearing shaft supports use high-quality, reliable BK, BF, FK, FF, EK and EF ball screw support bearings and precision ball screws. Support rail shafts provide an ideal solution to improve mechanical performance and efficiency.
Expertly crafted for precision, support rail shafts are designed to deliver superior stability and support for ball screws. Built with a durable structure and advanced engineering, these support rail shafts ensure smooth, accurate linear motion.
Specifications and characteristics:
1) 8mm shaft support fits well with the ball screw shaft as a whole.
2) Low noise
3) Low back gap
4) Timely delivery
5) Material is S45C carbon steel
6) Flexible minimum order quantity requirement of 8mm shaft support.
We can provide various sizes of end support rail shafts suitable for ball screws and screws.

Support Rail Shafts is a key component for supporting 8mm diameter linear shafts. 8mm shaft support is widely used in various automation equipment and precision drive systems. Flange shaft supports typically feature a two-piece design, allowing for easy access to the flange shaft support for maintenance and adjustments.This design of flange shaft support enables quick removal of the top part of the support.Flange shaft supports are versatile and find extensive use across multiple industries.
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.
