Metric Products & Components

Shaft collars are based on a simple design, using a ring and clamp screw (or set of screws), which loosen and tighten the collar around the shaft. The metric shaft collar acts as a mechanical stop or hold to secure metric shaft components, such as devices used for automation, motion control, and power transmission.

We produce a wide variety of versatile and easily installed metric shaft collars. View our metric round bore shaft collar inventory, which includes the following collar types:

• Metric One-Piece and Two-Piece split collars
• Metric Weldable and Wrenching Collars
• Metric Hinge Shaft Collars
• Metric Set Screw Collars
• Metric Heavy Duty Collars
• Metric Keyed Collars

A metric rigid shaft coupling connects two metric shafts, transferring power from one to the other. The shaft coupling must be a precise fit to maintain consistent and safe power transmission. For this reason, Stafford Manufacturing specializes in metric shaft couplings for a wide range of OEM and maintenance, repair, and operation (MRO) purposes. Explore our metric shaft couplings, which include the following coupling types

• Metric One, Two, and Three-Piece Split Couplings with and without keyways
• Metric Precision Sleeve Couplings
• Inch-Metric Conversion Couplings
• Remachinable Couplings

For efficient mounting and adjustment of metric shaft parts, view our metric mounting devices and components. Each of the following mounting collars and handles is built for maximum versatility and is customizable for precision applications.

Our metric Accu-Flange^TM mounting collars are made for unique applications involving metric pulleys, cams, and component-mounting devices. They feature standard keyways, three tapped holes, and three through holes. The Accu-Flange™ Shaft Collar utilizes a relief groove and integral clamp which can be machined for custom needs.

Benefits:

• Easy adjustments
• Perpendicularity at <0.001 TIR
• Secure attachment of pulleys, sprockets, and gears without welding
• No risk of shaft damage

These metric mounting shaft collars have universal tapped mounting holes, allowing multiple options for mounting components to the collar. Their smooth bores and tapped holes accommodate a variety of collar mount positions. Designed for use with soft or hard standard round shafts, over split hubs, or thin wall tubes, they are precision machined and easy to adjust with high clamping power.

Additional Features :

• Tight tolerances
• Easy adjustments
• High clamping power
• Universal tapped face holes
• No shaft damage
• Superior holding power

Stafford’s metric quick-release handles are made for easy and fast collar adjustments. They replace the need for clamp screws, making wrench-free repositioning possible. It’s an ideal solution for frequent linear adjustments, table-height or stroke-length adjustments, and instrument repositioning (not for use in rotary applications).

Additional Features :

• Rapid linear adjustments on clamping collars
• A single handle that replaces the need for a wrench and clamp screw
• Metric threading
• A knurled, textured OD for easy handling
