Studer A80 and B62 FULL bearing overhaul kits

If any of your bearings are noisy or suspect then it may be a good idea to replace all the bearings. On the A80 there are  a lot and will involve major disassembly and fine mechanical setup! 

There are two different kits dependent on 1/4" and multi-track models. All 3 motors are included and for the B62 also the pinch roller bearing.

A80, R, RC, QC & VU mk1, A81 1/4" and 1/2"

• 26 bearings
• Appropriate bellville washers
• Outer ciclips
• Some  inner circlips

A80 multitrack VU mk 2 - 4 & MR 1/2" - 2"

• 28 bearings
• Appropriate bellville washers
• Outer ciclips
• Some  inner circlips
• 
  

B62 2 versions 

• 18 bearings later m.  - Early version with roller bearing capstan = 20
• 18 bellville washers
• 8  circlips
  

All kits include pinch roller bearing and commonly replaced bellville washers, circlips, C clips and any special spacers.

PLEASE NOTE: Prior to Aug 2025 we had difficulty sourcing low noise tape tension roller bearings. These are the small bearings fitted to the tension rollers and often can be noisy and fickle.  Research has revealed that Studer had these specially made for them with very tight tolerances.  We have at last a solution and are trying a new manufacturer and so far are encouraged that they are reasonably silent.  In any event, Studer made sure that the original ones could actually be serviced! (unusual) and repacked. This we have confirmed with former Studer engineers. So - we actually supply these small bearings as NSK, APE or SKF new but also to give you the option of repacking your old ones (some special Kleuber low friction repacking grease supplied and we have available detailed instructions). So at least you have options and alternatives. 

Also in August 2025 we now have available specially made RF516 bearings fitted to many Studer machines (A80 multi tracks, B67, A810, A820 etc). These work really great and are far better than supplying a lower height bearing and spacer which we and others used to do.

Capstan motors need lubricating every ~500 hours or 6 - 12 months and full clean and bottom / top lubricant replenishment at ~2000 hours or 2 - 3 years. 

Reel motors need to have their bearings replaced every 2000 hours or 2 - 4 years. Do this and the motors will last a long long time. Most motors I have come across have never been serviced and the lubricating felts are dry. Luckily these old capstan motors are really robust and can be brought back to good serviceable condition. They are relatively easy to dismantle and once upgraded / serviced will run smoother with less noise. With a good clean, new bearings and a lubrication its surprising how well an old motor can run. Dont take a chance on dubious bearing sources or lubricants.  Get the full Nagravox kit for all your motors.

Later capstan motors use Isoflex PDP65 and no other lubricant should be used or mixed with it. Early B62 motors may use Mobil DTH-EH lubricant.
