The two-piece clamp-on design supports quick assembly and disassembly along the shaft, reducing downtime in production lines and equipment where frequent adjustments are necessary.
AZSSMUK Bore 1-1/4” Stainless Steel Double Split
Designed in stainless steel (1-1/4″ bore), this two-piece collar offers superior weldability and corrosion resistance. The lock design allows disassembly and reassembly anywhere along the shaft, enabling flexible configurations without removing other components. It is especially suited for environments with moisture exposure or corrosive elements, where stainless durability is preferred.
MECCANIXITY Shaft Collar 2″ Bore Double Split (2 Pack)
The MECCANIXITY collar set is designed for motor bases, machinery, and industrial automation. Made from carbon steel with a black finish, these collars provide reliable locking with a two-piece design that makes installation along a shaft straightforward. They’re marketed for general-purpose stop and alignment tasks in manufacturing and tooling setups.
uxcell 2pcs Double Split Shaft Collar, 1-1/16″
uxcell offers a two-piece design suitable for 1-1/16″ shafts with a 1-7/8″ outside diameter. The 1/2″ width collar uses black oxide-coated steel for improved durability and corrosion resistance. The split design supports precise positioning and easier adjustments along the shaft without removing components, making it a practical option for tight spaces.
SAFYY 2 Pieces Stainless Steel Double Split
The SAFYY stainless steel collars use 304 stainless for high resistance to moisture and corrosion, with a detachable two-piece design for flexible adjustment along the shaft. The 5/16″ bore size is suitable for light to medium-duty applications where stainless corrosion resistance and a strong, stable clamping force are valued.
Buying Guide
Key considerations when choosing a double split shaft collar include bore size accuracy, material, coating, and ease of installation. For high-load or outdoor environments, stainless steel or coated carbon steel offers better corrosion resistance. Two-piece designs enable easy repositioning without disassembling adjacent parts, while set screws add stiffness and security. Coatings like black oxide improve wear resistance and reduce galling, but stainless steel delivers superior corrosion resistance in humid or wetted settings. Consider the shaft diameter, the need for quick reassemblies, and whether a stainless option is warranted for longevity in challenging environments.
Material and finish vary by model: carbon steel with black oxide is a solid, cost-effective choice for many machines; stainless steel variants excel where rust and moisture are concerns. When selecting bore sizes, ensure precise matching to the shaft to prevent slippage. If modularity is essential, look for two-piece collars that can be moved without removing other components. Packaging and set screws are practical details to confirm for easy maintenance and future upgrades.
For installation, assess whether your system benefits from a clamp-on solution with a two-piece design or whether a more integrated collar would fit your assembly. Finally, verify compatibility with any surrounding hardware, such as motor bases, drive belts, or guide shafts, to ensure reliable performance over time.
