One-Piece Industry Standard Clamping Coupling with or without Keyway

Tolerances, surface finish
A good machined surface finish is sufficient.
Maximum allowable surface finish:
Rt max 16 µm (Ra 1 µm - Rz 5 µm)
Maximum permissible tolerances:
shaft h6 - hub H7 (up to 40mm d. diameter)
shaft h8 - hub H8 (over 42mm d. diameter)

Mt transmissible
Nr. 1 TLK 300 Mt = Mt cat.
Nr. 2 TLK 300 Mt = Mt cat. • 1.55
Nr. 3 TLK 300 Mt = Mt cat. • 1.85
Nr. 4 TLK 300 Mt = Mt cat. • 2.02

DM hub calculation
The pressure Pn in the hub can be compared to the inside
pressure on a thick hollow cylinder.

Screws center distance I = D + 12 + (dg/25.4) (screws fixed on the hub)
Flange thickness Sf = (dg/25.4) • 1.3 (screws quality 8.8)
Screws center distance I = d - 12 - (dg/25.4) (screws fixed on the shaft)
Flange thickness Sf = (dg/25.4) • 1.8 (screws quality 12.9)
Note: On request the type KLA501 can be supplied also with split rings: therefore the transmissible torque Mt increases. Please contact our technical department.

For exact tolerance values and DM hub calculation
see the technical data section.
