Mandrel for the diamond roll with high-precision bearings in bushes at both fixed and loose side: Bearings are clamped in half-liners with approx. 0.05 mm oversize.

Using a spacer the mandrel of the diamond roll may be used in different truing devices with diamond rolls.

The mandrels of the diamond roll are designed for oil mist lubrication. Lubrication requires ½ drop of oil (CL10) at 1 bar of dried and filtered compressed air.

Specifications

• Diamond roller mounting Ø: 52h2 mm
• Diamond roller mounting width: 50 mm
• Diamond roller external Ø: 90 mm – 140 mm
• Speed with oil mist lubrication: max. 9600 RPM

Here the bearings are clamped in half-liners with an air gap of approx. 0.05mm in the diamond roll truing device. The mandrel for the diamond roll is driven by means of a Synchroflex toothed belt drive with three-phase servomotor.

The mandrels of the diamond roll are designed for oil mist lubrication. Lubrication requires ½ drop of oil (CL10) at 1bar of dried and filtered compressed air.

Specifications

• Diamond roller mounting Ø: 52h2 mm
• Diamond roller mounting width: 135 mm
• Diamond roller external Ø: 90 mm – 140 mm

This mandrel for the diamond roll is equipped with Teflon sealing rings and high-precision bearings in the bushes at both fixed and loose bearing side. The Teflon sealing rings have the advantage that they are proof against dry running and don’t cause heating up due to friction. The mandrel for the diamond roll is supported in the half-liners of the diamond roll truing device and clamped with approx. 0.05 mm oversize.

Fixed bearing and loose bearing are operating at an overpressure of approx. 0.5 bar. An asynchronous motor and a toothed belt drive GT5MR are used for the drive.

• Diamond roller mounting width: 50 mm
• Diamond roller external Ø: 90 mm – 120 mm
• Speed with grease lubrication: max. 16000 RPM

The mandrel for the diamond roll is driven by means of a Poly-V belt RB J and a servomotor. The bushes of both fixed and loose bearing side comprise high-precision bearings with labyrinth packages.
