pressure roller

The pressure roller only fits

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

Installation isn't quite so easy; you have limited space, and the lower Teflon sliding disc tends to slip and fall into the device. Then it's a matter of searching, finding, and starting all over again :-)

Only use suitable pressure rollers.

The pressure rollers of the B77 only fit with 2 pieces

1 mm washers. You can't break the timing belt any faster or more effectively.

What a pity about such recordings!

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

We use only genuine rubber. After vulcanization and pressing the sintered bearing into the brass bushing, the round grinding and 45° chamfer are applied. This is the only way we can meet Studer and Revox specifications! All new orders will receive the new company name, abbreviated to "Premium-Hifi."

First, the copper washer goes on the axle, then a Teflon washer, then the pressure roller, another Teflon washer and only then the cover!

We've seen some of the most amazing things: sometimes all the discs are at the bottom, sometimes all at the top, sometimes no discs at all, and sometimes with too many discs, which causes the roller to jam! Often, the copper disc is missing, and then the pressure roller has too much play on the axle, and the tape can no longer be guided properly!

Here too we offer suitable accessories such as the stainless steel countersunk screw M3 x 8 mm the Teflon washers (sliding washers) 5 x 10 x 0.25 Copper disc 5 x 8 x 0.15 and so on.

Installation in the Revox A700 tape machine is particularly easy. Just unscrew the cover, replace the reel, put the cover back on, and that's it!

No discs are required and must not be used! The pressure rollers are always lubricated with sintered bearing oil for life.

Like the Revox A700, Studer A67, and B67, the Studer A807 doesn't use any discs. It couldn't be easier. Loosen the screw, remove the cover, replace the pressure roller with the premium hi-fi quality pressure roller, and reassemble!

The exploded drawings are taken from the original service manuals of the respective devices and have been redrawn by us.

Unscrew the lid, replace the pressure roller, screw the lid back on – that's it! What was expected of amateurs was simply left out of the discs for the professionals!

If the pressure rollers are placed next to each other, the size difference is immediately apparent.

Condition and without comparison the difference is difficult to see.

The left pinch roller has an 8.0 mm diameter and a sintered bronze bearing. Even the 8.6 mm pinch roller would rub against the erase head of the Revox B710.

Here too, the bearings are oiled and therefore maintenance-free!

The right pinch roller could also accommodate the 8.0 mm pinch roller. This would not change the speed. The speed is determined solely by the circumference and rotational speed of the capstan shaft, but installing the 8.0 mm pinch roller would be completely wrong!

First, the spacer washer, then a Teflon washer, the pressure roller, another Teflon washer and finally the shaft retaining ring are fitted onto the axle.

There is no groove for the shaft retaining ring. The shaft retaining ring is pushed onto the axle until the pressure roller has minimal play (0.1 mm).

Left pressure roller of the Revox B710 with 13 mm pressure roller.

In relation to the capstan shaft, the 13 mm reel is clearly visible.

If you want to estimate the size of the pinch rollers, turn on the cassette deck and press the Clear button under the cover. The tape head bridge, including the pinch rollers, will then move upwards for cleaning, allowing you to see the pinch rollers.
