What is a Linear Slider?
A linear slider is a precision motion component that pairs a linear ball bearing with a mounting housing, allowing smooth, guided travel along a shaft. Unlike a bare bearing, the housing provides structural mounting points, making the slider easy to integrate directly into a machine frame. Linear sliders are core components in CNC axes, 3D printer carriages, and automated linear-feed systems, where consistent, low-friction travel and secure mounting are essential.
Advantages of SIQIANG 16mm Linear Sliders
Two Structural Options for Every Application
Open-type designs (SC, SBR series) allow easy visual inspection and lubrication access, while enclosed SCS blocks offer added rigidity and dust protection — covering both light-duty and higher-load use cases.
Stable Load Performance
Precision-ground steel balls and hardened raceways deliver consistent dynamic load ratings (e.g. 774N on our SCS16LUU), suitable for continuous industrial operation.
Low Friction, Smooth Travel
Optimized ball-to-raceway contact minimizes resistance, supporting high-speed, repeatable linear motion.
Dedicated Shaft Support Units
Our SHF16 and SK16 shaft supports secure and align 16mm shafts at each end of the travel path, completing a full linear motion system without third-party sourcing.
Custom Sizing & OEM/ODM
Housing shape, sealing rings, surface treatment, and packaging (boxes, cartons, logo) can all be customized to your specifications.
Verified Quality System
Every batch is produced under ISO9001-certified processes and passes salt spray and life-cycle testing before shipment.

FAQ — Frequently Asked Questions About Linear Sliders
Q: What is the difference between open-type and enclosed linear sliders?
A: Open-type sliders (like our SC and SBR series) allow easier lubrication access and visual inspection, while enclosed types (like SCS) offer additional dust protection and rigidity — the right choice depends on your operating environment.
Q: What is the minimum order quantity for linear sliders?
A: MOQs for standard 16mm models typically start around 100 pieces, though sample or trial quantities can often be arranged — contact us with your specific model for confirmation.
Q: What is the typical lead time?
A: In-stock standard sizes usually ship within 15–20 days; customized housings, sealing, or finishes generally take 30–40 days depending on order volume.
Q: How long is the warranty on your linear sliders?
A: We provide a 1-year warranty and recommend regular application of anti-rust oil; components damaged under normal use are replaced free of charge.
Q: Can you provide samples before a bulk order?
A: Yes, we can arrange sample production for evaluation before you commit to a bulk order.
Q: What certifications do your linear sliders have?
A: Our production system and products are certified under ISO9001, RoHS, and REACH.
Q: Do you accept custom packaging and branding?
A: Yes, we offer customizable sealing rings, plastic bags, boxes, and cartons, including logo printing for OEM/private-label buyers.
Q: Can the shaft support units be ordered separately from the slider blocks?
A: Yes, our SHF16 and SK16 shaft supports can be purchased independently to complete or expand an existing linear motion system.
Q: Do you provide installation guidance?
A: Yes, we provide installation videos and assembly tutorials to support setup on your production line.
Q: What load capacity do your linear sliders support?
A: Dynamic load ratings vary by model — for example, our SCS16LUU is rated at 774N. Contact us for the full specification of any specific model.
Q: Which countries do you export to?
A: We export primarily to Southeast Asia, Europe, Africa, and South America, with a growing customer base in the US and Brazil.
Q: Can linear sliders be customized for shaft sizes other than 16mm?
A: Our current linear slider line is built around the 16mm shaft standard; for other sizes, please contact us to discuss feasibility.
