About Keyway Broaches

Splined Rotary Shafts

Good for hydraulic systems, machine tools, and other high-torque applications, these shafts have teeth that transmit high rotational loads.

Sleeve Splines and Bearings

Often used in wet and dirty environments, these sleeve splines and bearings create a compact linear and rotary motion system.

Ball Screw/Splines and Bearings

From one compact system, transmit linear or rotary motion or both at once (sometimes called spiral motion). Because of these different motions, these ball screw/splines and bearings create efficient, fluid movements in complex automated applications, such as pick-and-place robots.

Ball Splines and Bearings

Create a compact linear and rotary motion system for applications requiring complex, fast movements, such as robotics.

Splined Flexible Shaft Couplings

For use with splined shafts, which are commonly found in gearboxes and pumps, these couplings are capable of transmitting more torque than couplings for round and keyed shafts.

Splined-to-Keyed Flexible Shaft Couplings

Connect splined shafts to keyed shafts. These couplings are commonly used to connect hydraulic pumps, compressors, and other heavy duty equipment, which often have splined shafts, to electric motors and other components that often have keyed shafts.

Keyless Locking Shaft
Couplings for Overhung Loads

Support the weight of a motor and transfer torque to another shaft at the same time with these couplings.

Mounted Linear Bearings for Ball Splines

A flange with mounting holes makes it easy to attach a load to these bearings. Create a compact linear and rotary motion system for robots and other applications requiring complex, fast movements, by combining them with ball splines.

Linear Bearings for Ball Splines

Combine these bearings with a ball spline to create a compact linear and rotary motion system for applications with fast, complex movements, such as robotics.

Broaching

Bushings for Keyway Broaches

Use individual keyway broaches in a variety of arbor hole sizes. Bushings rest inside the arbor hole of your workpiece and act as guides to ensure rigid and accurate keyway cutting.

Keyway Broaches

Cut precision keyways.

Keyway Broach Sets

Sets contain combinations of broaches and bushings and include the necessary shims.

Single-Pass Keyway Broaches

Save time by cutting keyways in one pass. These broaches are longer and have thicker teeth than standard broaches, so you won’t need multiple passes or shims.

Shims for Keyway Broaches

When broaching in multiple passes, shims are necessary to ensure full keyway depth.

Hex Broaches

Transform round holes into finely finished hex-shaped holes.

Rotary Hex Broaches

Used in CNC and milling machines, these broaches turn round holes into hexagonal ones with more accuracy than traditional push broaches.

Holders for Rotary Broaches

Use these holders to secure your rotary broach in a lathe, milling machine, or CNC machine.

Rotary Square Broaches

Changing round holes into a square shape more accurately than traditional push broaches, these broaches go in CNC and milling machines.

Square Broaches

Transform round holes into finely finished square holes.

Keyseat Broaches

Cut precise notches for machine keys in rotary shafts.
