Key Types We Source

Parallel Keys

DIN 6885 and GB/T 1096 square and rectangular keys for shaft-hub torque transmission.

Woodruff Keys

GB/T 1099 and DIN 6888 half-moon keys for light and medium duty applications.

Taper Keys

Taper and gib-head keys for heavy-duty, removable shaft-hub connections.

Spline Shafts

Involute and straight-sided splines for high-torque, precision-aligned drives.

Custom Keys

Special-section keys per drawing for gearboxes, pumps and industrial machinery.

How to Choose the Right Key

Select the key type by torque and duty: parallel keys for standard transmission, Woodruff keys for light loads and misalignment tolerance, taper keys for heavy-duty removable fits, and splines for the highest torque density. Match the key cross-section to the shaft diameter per the standard table, and confirm the keyway tolerance class for the fit you need. Provide shaft diameter, hub bore and transmitted torque, and our engineers will size the correct key standard and material.

Frequently Asked Questions

What key standards do you manufacture to?

We supply DIN 6885, GB/T 1096/1099, ISO 773/3912 and ANSI B17.1 keys in metric and imperial sizes.

How do I select the right key size?

Key cross-section is determined by shaft diameter per the standard table; length is set by the hub length. Provide the shaft size and torque and we will size it for you.

Can you supply keys for custom keyways?

Yes — custom cross-sections, lengths and materials are available per drawing, with samples in 1–3 days.

Do you offer hardened keys?

Yes, keys can be induction-hardened or through-hardened to meet wear requirements for high-cycle applications.
