The SCS10 shaft collar marks a pivotal step in the SCS series: it is the first model to offer an optional 3 mm keyway, combining radial clamping force with the rotational constraint of a keyed connection. This dual-locking mechanism makes the SCS10 the preferred choice for 10 mm shafts that must resist both axial displacement and torsional loading simultaneously — a requirement that a plain split collar alone cannot fully satisfy in dynamic drive applications.
Sharing the same 30 mm OD and 10 mm face width as the SCS08, the SCS10 allows engineers to standardise collar mounting pockets across shaft sizes while gaining torque-transmission capability. The wall thickness of 10 mm per side remains generous relative to the 10 mm bore, ensuring the keyway slot does not compromise the split mechanism.

🔗 First Keyway-Capable Model
3 mm keyway slot enables simultaneous axial and rotational shaft locking — absent from SCS06 and SCS08.
⚙ Shared 30mm OD with SCS08
Identical mounting pocket geometry allows SCS08 and SCS10 to be used interchangeably in the same housing design.
📈 Dual-Lock Mechanism
Friction clamp + key handles dynamic loads that would cause a plain split collar to micro-slip under repeated torque reversals.
⚖ Standard ISO Key Compatibility
3 mm keyway accepts DIN 6885 parallel keys available from any industrial fastener supplier worldwide.
10 mm shafts are the standard output size for many compact chain-drive gearboxes in light conveyors. An SCS10 with keyway locks the sprocket both axially and rotationally, replacing a traditional circlip-plus-key arrangement with a single adjustable component that can be repositioned during changeovers without shaft rework.
In twin-rail linear systems, SCS10 collars fitted to guide rods serve as adjustable hard stops for carriage travel limits. The keyway prevents rotation under repeated impact loads — critical in high-cycle pick-and-place automation where collar spin would gradually shift the travel limit position.
Rotary encoders and miniature electromagnetic brakes on 10 mm shafts require precise axial positioning of their discs. Two SCS10 collars sandwiching the disc provide a fully adjustable, repeatable datum that survives industrial servo drive vibration environments.
The 3 mm keyway accepts a standard ISO 773 / DIN 6885 3×3 parallel key. When paired with a mating shaft keyway, the key transmits torque while the split clamp prevents axial walk — complementary rather than redundant retention. A practical pairing technique is two SCS10 collars flanking a timing pulley or sprocket hub: the keyway prevents rotation under load while the collars prevent axial translation under belt tension. For custom configurations, contact the EP engineering team.
A keyway introduces a stress concentration in the bore wall. However, at 3 mm depth with 10 mm wall thickness per side, the remaining cross-section is more than adequate for axial loads typical of shaft-collar duty. For extreme shock loads contact EP for a stress analysis specific to your application.
Yes. Standard catalogue delivery is without keyway. Specify 'with keyway K=3 mm' in your order or drawing to receive the keyed version. Mixed orders (some with, some without) are accommodated above MOQ.
The 3 mm keyway is sized to ISO 773 / DIN 6885A: 3 mm wide × 3 mm deep. Use a standard 3×3×L parallel key of length matching the hub engagement.
MOQ is 100 pieces. Sample evaluation sets may be discussed with the EP sales team via the contacts page.
