We are offering Two Piece Shaft Collars to our clients. Ruland manufactures shaft collars in multiple styles to fit shafts. Ruland shaft collars are available in a variety of materials and finishes.
Ruland shaft collars are offered in multiple styles to fit shafts ranging in the inch series in the metric series, in a variety of materials and finishes. Collars are stamped with the Ruland name and the bore size for easy identification.
Extra steps are taken in the manufacture of Ruland shaft collars to provide important performance benefits. For example, Ruland collars are single point faced (indicated by the circular groove on the face) during the boring operation to insure perpendicularity of the face to the bore. Perpendicularity is important for alignment when collars are used as a bearing face, a mechanical stop, or for mounting other components.
One-piece clamp style collars wrap around the shaft for even distribution of clamping forces. This results in a tight fit and greater holding power, without the shaft damage caused by set screws. Ruland uses carefully selected materials and proprietary processes to ensure that the clamping gap remains open for simpler and more precise adjustment, installation and fit.
Two-piece clamp style collars offer the same benefits of the one-piece clamp collars with additional versatility and convenience. They are easily disassembled, reducing labor and downtime when adjustment, removal or replacement is necessary. Ruland keeps both halves of its two-piece collars together throughout the manufacturing process to assure a perfect match for proper fit, holding power and alignment.
Clamp style collars with threaded bores are also available. Threaded collars provide axial holding power superior to smooth bore collars, while offering easier installation and adjustment than solid ring locking devices. A diverse list of thread sizes and pitches, including metric and locknut threads, are offered.
Set screw collars are most effective when used on a shaft made of a material that is softer than the set screw. Ruland set screw collars are furnished exclusively with forged socket set screws for greater torque capacity and improved holding power. Forging of the stainless steel set screws has the additional benefit of work hardening, which results in stainless steel with elevated hardness and performance.
