Ruland TCN-03-F is a clamp type bearing locknut with a 0.664″ – 32 TPI bore, 1 1/2-in. OD, and 0.438-in. width. It is manufactured to AFBMA standards and designed for use on high precision spindle bearings. Ruland double taps threads to ensure a precise and burr-free finish allowing for easy installation and removal, proper fit, and extended shaft life. The clamp-style design will not mar the shaft. It is commonly used for guiding, spacing, stopping, mounting, and component alignment. Equipment manufacturers benefit from the tightly controlled face to bore perpendicularity (TIR of ≤ .0005″).
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. TCN-03-F is stamped with the Ruland name and locknut size for ease of identification. Forged screws test beyond DIN 912 12.9 standards to ensure maximum holding power. It is manufactured from solid bar stock sourced from select North American mills and machined to a fine burr-free finish. Ruland uses 1215 lead-free steel with a proprietary black oxide finish that produces a fine glossy finish while increasing holding power and resisting corrosion. TCN-03-F is RoHS3 and REACH compliant and manufactured in our Marlborough, MA factory under strict controls using proprietary processes.
