Black Oxide finish on our mild steel collars is formulated as part of the total performance of the collar. The black oxide affects the anti-stick-slip characteristics and helps keep the torque rating of the screw within its design parameters. Black oxide also has corrosion Continue reading “What finishes does Climax offer on shaft collars?”
While there is no formal industry standard for shaft collars, the dimensions of most manufacturers’ collars are fairly uniform. In most applications, the shaft collar bore (ID) is considered a critical dimension while other dimensions such as outer dimension and width are considered non-critical. Dimensions for Climax shaft collars can be found on our website and in paper format. For shaft collars needing special dimensions contact our customer service department.
The relief cut removes some of the rigidity of a one-piece clamping collar to allow the screws to clamp more evenly and securely. A relief cut is important only on smaller bore collars because of the ratio of the screw to the collar material – the screw provides much of the clamp load. Climax puts a relief cut in collars with a 1 ½” bore or smaller. Relief cuts can be found on metric collars 19 mm and smaller and on our threaded collars sizes under 1 ¾-16 in.
The face groove on clamping collars indicates the face that should be placed against a bearing or other component requiring a perpendicular to bore orientation. For two-piece clamping collars, the face groove also helps keep the two halves of the collar properly oriented during installation.
Shaft collars can be welded with some exceptions. Mild steel and stainless steel materials contain sulfur and other additives which allow for welding. However, the lowest possible current and adequate ventilation should be employed. Be sure to remove screws before welding. However, in no cases should collars with zinc plating be welded. The welding process on a zinc plated product will produce noxious fumes. Welding can be done safely on a black oxide finished product. Extreme caution is recommended when welding imported collars because of the inconsistency of the material and finishes.
The primary purpose of a shaft collar is to resist an axial load. That is to hold itself in place despite pressure along the axis of a shaft. The axial holding power is primarily a function of screw size and applied torque. However, other factors such as presence of oil, temperature, and the finish and hardness of the shaft can impact the holding power.
Backlash is the slop or play in a mechanism caused by gaps between the parts. Generally, this is defined as the amount of clearance in the device after motion is applied and before the mechanism activates. An example would be turning a steering wheel in a car, and feeling the loose motion before the steering engages. Backlash is usually not desired in most industrial applications, although occasionally some amount of backlash is necessary.
Abrasive hardware describes a group of tooling components that hold abrasive finishing products such as cartridge rolls, cut-off wheels, polishing buffs, wire brushes, and finishing wheels in place. Designs will vary depending on the abrasive product being used. Always remember to use recommended safety equipment when working with hand and power tools.

Climax manufactures rigid set screw couplings and rigid clamping couplings. We also offer customized dimensions, specialized plating and manufacture from a variety of materials.
Set Screw Couplings are secured to the shaft by set screws that impinge upon the shaft. Set screw couplings are also available with a keyway for keyed shafts.
Clamp Couplings are designed in a one-piece and Continue reading “What type of rigid coupling does Climax manufacture?”
Abrasive sanding drums are used to mount an abrasive sanding sleeve. The rubber drum expands to hold the sanding sleeve in place. Sleeves are secured on the drum by controlled expansion of the solid rubber drum spindle. The rubber provides a cushioned backing to assure a smooth, even finish during use. Always remember to use recommended safety equipment when working with hand and power tools.
