Clamp shaft collars do not mar the shaft, are easy to remove and are indefinitely adjustable
They are commonly used for guiding, spacing, stopping, mounting and component alignment
Equipment manufacturers benefit from the tightly controlled face to bore perpendicularity of Ruland shaft collars （TIR of 0.002" or 0.05 mm）
Perpendicularity is critical for alignment when the shaft collar is used as a load bearing face, mechanical stop or for mounting components such as gears or bearings
Proprietary processes have been developed by Ruland to maintain superior fit, finish, and holding power
Ruland stamps the name and bore size on every shaft collar for ease of identification
2 piece styles are mated throughout the manufacturing process for proper fit and alignment
Forged screws test beyond DIN 912 12.9 to ensure maximum holding power
All shaft collars are machined from solid bar stock to a fine burr free finish and sourced exclusively from North American mills
Ruland uses high grade 2024 aluminium for increased screw seating torque
All products are RoHS2 and REACH compliant and manufactured in our Marlborough, MA factory
One and two piece collars in aluminium Collars do not score the shaft Easily installed and adjusted
