Ruland Manufacturing offers shaft collars that can be used in equipment such as motors, gearboxes, linear actuators, packaging equipment, printing presses, medical devices and precision instruments.

The company’s shaft collars, which provide controlled face tolerances and high holding power, are single-point faced during the boring process to ensure a high level of face-to-bore perpendicularity.

This results in a face run-out of TIR less than 0.05mm (0.002in) on standard collars, with even tighter tolerances on bearing locknuts and special designs.

The face-to-bore relationship is important for many applications where components such as bearings need to be properly aligned on the shaft.

It also creates even pressure on the interfaced components, prolonging their life, and reduces the likelihood that the shaft collar will shift when it is subjected to shock loads.

A circular groove on the shaft collar indicates that it has been single-point faced.

Ruland collars should be installed so that the circular groove is on the side that will receive the shock load or against the components that need precise positioning or even pressure.

The shaft collars are offered in aluminium, black oxide carbon steel, stainless steel and engineered plastic.

One- and two-piece clamp shaft collars are available with bore sizes from 3mm to 80mm in the metric series and from 1/8in to 6in in the inch series.

Clamp-style shaft collars wrap around the shaft for an even distribution of clamping forces.

This results in a tight fit and greater holding power, without the shaft damage caused by set screws.

Two-piece clamp-style collars can be installed on the shaft without removing other components.

Ruland uses forged socket hardware in all its shaft collars, allowing for higher screw torque and increased holding power.

All of the company’s products are RoHS and Reach compliant.

They are manufactured in Ruland’s US factory under strict controls using proprietary processes, high-quality materials and excellent finishes.

The company’s complete product line includes shaft collars and rigid couplings and five types of zero-backlash motion control couplings: beam couplings, bellows couplings, oldham couplings, miniature disc couplings and curved jaw couplings.
