Shaft Collars & Couplings for Maintenance, Repair, and Retrofit

Stafford Manufacturing’s SPARC™ collar for prototyping and repair comes in either a one- or two-piece split master collar design. We offer aluminum, stainless steel, and steel collars in three sizes. Our SPARC™ system allows you to use 3D-printed inserts and create working prototypes within hours. You can create special-purpose repair shaft collars to fit almost any shaft size. View our catalog for more details.

We offer weldable shaft collars in one- and two-piece split, inch or metric sizes, and with or without keyways. Our weldable shaft collars are made of 1018 steel and lead-free for safe welding. They offer improved holding power compared to set screw collars and have a smooth bore to prevent shaft damage. View our products for more details.

Our wrenching collars come in one- or two-piece split and hinged designs and also come in kits. The collar ID matches most standard shaft or pipe sizes and can be placed anywhere on the shaft or pipe. The wrench flats allow for installation with a standard open-end wrench and torquing in place without damaging the pipe or shaft. View our products to learn more.

Stafford Manufacturing’s remachinable shaft collars can be machined on-demand by end users according to the configurations, sizes, and shapes they need. Users can reduce the costs and time spent by custom-machining the shaft collar’s bore size in-house. View our products for more details.

Our 100:1 phase adjuster repair couplings maintain shaft alignment and allow for precise and static phase adjustment by hand. They can be used as a component mount or rigid coupling and have a standard keyway. Stafford’s rotary encoder collars can be used for new applications and retrofitting. They add feedback capabilities to the machinery, and their face/OD targets offer design flexibility. View our products to learn more.

Stafford Manufacturing offers one-piece split drill stop clamp collar kits, one-piece split tool setting kits, one-piece and two-piece remachinable shaft collar kits, two-piece split wrenching collar kits, and two-piece split pipe wrenching collar kits. These kits allow you to instantly create custom parts to suit your specific design requirements, such as for prototype design or maintenance.

We offer remachinable one-piece split couplings in inch or metric options and with or without keyways. View our products to learn more.

Our customizable steel clamp couplings come in one- or two-piece split options and various styles, such as stepped or straight-thru bores and with or without keyways. They are made from stocked blanks to provide fast turnarounds, especially for low-volume runs. View our products to learn more.

We offer adjustable thrust collar assemblies and axial thrust collar assemblies that can be mounted anywhere on the shaft and provide high levels of axial force. Axial thrust collar assemblies allow for bi-directional axial adjustability along a shaft for pre-loading bearings or moving heavy components along a shaft. The Axial Thrust assembly is ideal for removing shrink-fit or frozen parts, as it can be infinitely positioned along the shaft and offers 5,000 to 8,000 lbs of thrust.
