Pinchrollers

The pinch roller fits only

Revox A77 Mk I to MK IV. No other Revox device uses this pressure roller.

The installation is not quite so easy, you have little space and the lower Teflon sliding slipper like to slip away and falls into the device!

Use only suitable pinch rollers.

The pinch rollers of the B77 only fit with 2 pieces

1 mm washers. You can not break the synchronization faster and more effectively.

Pity about such shots!

also suitable for Revox A700, PR99 MKI, MKII, MKIII, C270, C274 and Studer A67, B67, A807, A810.

With us only real rubber is used. After vulcanising and pressing the sintered bearing into the brass bushing, the round bevel and the 45 ° chamfer take place.

Only then can we meet the specifications of Studer and Revox!

First comes the copper disk on the axle, then a Teflon disk, then the pinch roller, another Teflon disk and only then the cover!

We have already experienced the most amazing things, all the discs below, all the above, sometimes completely without discs and also with too many discs, then the roller clamps nicely! Often only the copper disc is missing, then the pinch roller has too much play on the axle and the belt can not be properly guided!

Again, we offer suitable accessories such as the stainless steel countersunk screw M3 x 8 mm

the teflon discs (sliding washers) 5 x 10 x 0.25

Copper disc 5 x 8 x 0.15

and so on.

The installation in the Revox A700 tape machine is particularly easy. Unscrew cover, replace roller, cover it that's it!

No discs are needed and must not be used!

As with the Revox A700, Studer A67 and B67, no discs are used on the Studer A807.

The exploded views are taken from the original service manuals of the respective devices.

Unscrew the cover, replace the pressure roller, screw on the cover again - that's it!

If the pinch rollers are next to each other, the size difference can be seen immediately. In the built-in

Condition and without comparison, the difference is difficult to see.

The left pinch roller with 8.0 mm diameter and sintered bronze bearings.

Even the 8.6 mm pressure roller would grind here at the erase head of the Revox B710.

Again, the bearings are oiled and thus maintenance free!

The right pinch roller could also accommodate the 8.0 mm pinch roller. It would not change the speed. The speed is determined solely by the circumference and speed of the capstan, but the assembly of the 8.0 mm pressure roller would be wrong!

First, the spacer, then a Teflon disk, the pressure roller, another Teflon disk and finally the shaft securing ring is fitted to the axle.

There is no groove for the shaft securing ring. The shaft lock ring is pushed onto the axle until the pinch roller has minimal play

Left pinch roller of Revox B710 with 13 mm pinch roller.

In relation to the capstan, the 13 mm roller as such is easy to recognize.

If you want to estimate the size of the pinch rollers, switch on the cassette deck and press the Clear button under the flap. Then the Tonkopfbrücke incl. The pinch rollers for cleaning moves up and you can see the pinch rollers.
