Buying Guide

Choose the right bore size

Match the collar bore to your shaft diameter—options here include 1.00", 2", 2.5", and 3"—to avoid slippage or machining

Pick split vs two-piece style

Double-split (four-bolt) collars offer easier installation on mounted shafts while two-piece collars clamp evenly without removing shaft components

Consider material and finish

Stainless steel (303/304) resists corrosion for marine or wet environments; carbon steel with black oxide gives higher hardness at lower cost

Check clamping hardware and torque spec

Look for collars with quality clamp bolts and clear torque recommendations to ensure consistent holding force and avoid deformation

Evaluate pack size and value

Multi-packs, such as 4-packs of 1" collars, can lower per-unit cost for production or maintenance inventories while maintaining consistent specs
