Products Description
The aluminum shaft support unit SHF16 is a flat-mount aluminum shaft support unit engineered to hold and align 16mm optical shafts in linear motion assemblies. Its split-clamp design allows tool-free shaft insertion and secure locking, ensuring zero-play alignment across the full travel range of your linear system.
Manufactured by Zhejiang SQ Bearing Co., Ltd. - a high-tech enterprise founded in 2007 with over 100 CNC and grinding machines across 19,800 m² of production floor - the SHF16 is backed by ISO 9001 quality management processes and exported to customers across Southeast Asia, Europe, Africa, and South America.

Features & Benefits
Split-clamp bore design
Top-slot clamp allows quick shaft insertion and precise tightening without disassembly of the linear unit.
High-rigidity aluminum body
Lightweight yet structurally rigid aluminum alloy body minimizes vibration-induced deflection in high-speed reciprocating systems.
Precise bore tolerance
Machined to tight dimensional tolerances for consistent shaft-to-support concentricity - critical for smooth linear bearing travel.
Dual-bolt flat base mount
Two-point symmetric bolt pattern distributes mounting load evenly and simplifies alignment to frame structures and extrusion rails.
Corrosion-resistant finish
Surface treatment ensures resistance to oxidation and light chemical exposure in typical factory automation environments.
Custom branding available
OEM laser engraving, custom packaging (cartons, labels, retail boxes) and sample prototyping available on request.

FAQ
Q: What shaft diameter does the SHF16 support?
A: The SHF16 is designed for 16mm diameter optical shafts (linear round shafts). If you require a different bore size - such as SHF8, SHF10, SHF12, SHF20, or SHF25 - please contact us. Custom bore sizes are available on request.
Q: Can I order samples before placing a bulk order?
A: Yes. We support sample prototyping and provide real-product photography for evaluation. Sample lead time and cost will be confirmed by our team based on your requirements. Contact us via the quote form.
Q: Is OEM / private label packaging available?
A: Yes. We support custom packaging including plastic bags, retail boxes, outer cartons, and custom logo printing. Brand-specific box and carton design is also available. Please share your requirements when requesting a quote.
Q: What is the warranty policy?
A: All SQ products come with a 12-month quality warranty from date of shipment. We recommend applying anti-rust oil during storage and regular lubrication during operation. Damaged components within the warranty period will be replaced free of charge subject to inspection.
