Product Overview
The GBC-SCS14 marks the transition point in the SCS series where the clamping screw steps up from M4 to M5, delivering approximately 60% more clamping torque capacity for the same wrench effort. At 14 mm bore, 35 mm OD, and 12 mm face width, the SCS14 targets the class of light-industrial shafts found throughout packaging machinery, food-processing conveyors, and pharmaceutical tablet-press drives — applications that demand reliable axial retention across extended continuous-duty cycles without scheduled re-tightening. The 5 mm keyway option allows the collar to double as a torque-locking element on cam and eccentric drive shafts, eliminating a separate locking hub and reducing assembly part count.
Key Features
Shaft Surface Protection
The split-clamp principle spreads clamping force uniformly across the full bore circumference, preventing the point indentation and fretting corrosion that set-screw collars create at the contact point. The shaft remains undamaged and fully repositionable throughout the product's service life.
M5 High-Torque Clamping
The M5 socket-head cap screw provides a proof-load capacity approximately 60% higher than the M4 screws used in smaller SCS collars. This increase in clamping force is matched to the larger bore and OD at this size range, ensuring reliable retention under sustained bidirectional axial loading.
Dual Axial-Location Function
A single collar acts as a positive end-stop against a bearing or housing shoulder. A pair of collars sandwiches any shaft-mounted component at a freely adjustable position — a versatile alternative to machined shaft steps that eliminates re-machining costs when axial positions need to change.
Lightweight Aluminium Alloy Body
Aluminium alloy construction keeps collar mass below 30 g for all bore sizes in the 14 mm OD range, minimising the rotational inertia penalty in dynamic drive assemblies and the static load penalty on vertically mounted shafts.
5 mm Keyway Option for Torque Locking
A standard 5 mm DIN 6885 keyway can be broached on request, enabling the collar to transmit rotational torque simultaneously with axial positioning. Specify at order — default supply is plain bore.
Typical Application Scenarios
Packaging Machinery
Horizontal form-fill-seal machines route film through 14 mm idle-roller shafts. The SCS14 sets lateral film-track position and acts as a positive thrust face against the roller bearing, preventing lateral walk during high-speed sealing cycles that impose sustained axial loads on the film-guide rollers.
Food-Processing Conveyors
Stainless-compatible aluminium SCS14 collars position nylon rollers on 14 mm stainless guide shafts in fruit-sorting and vegetable-washing conveyors. The clamp design avoids threaded holes in the shaft, preserving the smooth, cleanable surface required by food-hygiene standards.
Pharmaceutical Tablet Presses
Cam-track guide shafts in rotary tablet presses use SCS14 collars with keyway to lock die-feed cam followers in precise axial positions, maintaining consistent tablet weight across all tooling stations during multi-hour production runs.
Dimensional Guide & Shaft Fit Specification
The three principal dimensions — bore d = 14 mm, outer diameter D = 35 mm, and face width B = 12 mm — define the spatial envelope of the collar in an assembly. The slot width W = 1.5 mm runs the full face width and is the feature that allows the collar to flex radially as the M5 screw closes the gap. Specify the mating shaft to ISO 286 h6 tolerance (14.000 / 13.989 mm) for the optimal combination of sliding fit before clamping and maximum retention force after clamping.
GBC accepts custom orders for alternative bore tolerances (H7, js6), reduced OD profiles to clear adjacent components, extended face widths for higher axial holding force, and surface treatments including natural anodize, hard anodize (25 µm), and electroless nickel plating.

Model Selection Guide
For a 13 mm shaft, the GBC-SCS13 provides the M4 screw variant at 30 mm OD. Stepping up to 15 mm bore — the first metric-series standard at M5 — is the GBC-SCS15, which shares the same 35 mm OD and 12 mm face width.
| Model | Bore | Relation |
|---|---|---|
| GBC-SCS13 | 13mm | ← Smaller |
| GBC-SCS14 | 14 mm | ◀ Current |
| GBC-SCS15 | 15mm | → Larger |
Installation Procedure
- Prepare the shaft: Clean and degrease the shaft in the clamping zone. Verify diameter within h6 tolerance (14.000 / 13.989 mm). Remove any burrs or nicks with a fine file.
- Slide and position: Slide the GBC-SCS14 onto the shaft to the required axial location. Use a calibrated depth gauge or a pre-machined spacer as a reference for repeatable positioning.
- Clamp progressively: Using a 5 mm hex key, tighten the M5 screw in two or three incremental steps, checking axial position after each step to correct any settling. Torque the M5 screw to 4.0–4.5 N·m using a 4 mm hex key. For food-grade installations, use an A2 stainless M5 screw and apply food-safe anti-seize paste to the threads.
- Load test: Apply the expected axial service load (manually or via the driven machine) and confirm zero collar movement. For vibrating or cyclic-load applications, re-verify screw torque after the first full operating shift.
