Description:
Locating cylinder Ball Lock for mechanical locating and clamping system.

Material:
- Locating cylinder: carbon steel.
- Balls: roller bearing steel.

Version:
- Locating cylinder tempered and black oxidised.
- Balls hardened and bright.

Function / Application:
- Tightening the thrust screw presses the centre ball downwards and forces the three locking balls outwards into the receiver bush.
- Designed for rapid, precise positioning and clamping; catalogue states machine setup times can be up to twelve times shorter than conventional methods.

Dimensions / Variant Data:
- Grid plate thickness: 25 mm.
- D: 20 mm.
- D1: 40 mm.
- D2: M6.
- L: 44.5 mm.
- L1: 10 mm.
- SW: 3 mm.
- Holding force F: 13.3 kN.
- Maximum tightening torque: 4 Nm.
- Repair kit order no.: K0935.920025.

System Information:
- Mechanical locating and clamping system enables base and tooling plates to be precisely positioned and fastened in a few seconds.
- System consists of a locating cylinder, centring bush and receiver bush.
- Recommended sequence: mount two receiver bushes on the machine table/base plate and two centring bushes on the clamping plate; insert locating cylinders through the centring bushes into the receiver bushes; turn the set screws in the locating cylinders approximately two rotations to clamp.
- A grade I centring bush and a grade I or grade II centring bush should be installed as far apart as possible in each fastening plate; more than two positioning points do not improve positioning accuracy.
- When more than two locating cylinders are used for additional holding force, the additional holes in the fastening plate should be 0.4-0.8 mm larger than the selected locating-cylinder diameter.
- With centre distance tolerance +/-0.005 mm and two grade I centring bushes, repeat accuracy within +/-0.013 mm can be achieved.
- With centre distance tolerance +/-0.03 mm and one grade I plus one grade II centring bush, repeat accuracy within +/-0.04 mm can be achieved.
- Grade II centring bushes have a larger internal diameter to accommodate the larger centre-distance tolerance.
