I have to say by far, these two videos gave me full insight into the repair job of the pulleys and bearings and notably shows there are 3 bearings.
Just shows you can save so much money by getting non-manufacturer parts. SIP pulleys are £75 a pair, the belt is £24 and the bearings £21 each.
Manufacturer parts total: £237 !!!!!!!!!!
My total: £81 ish
Repair videos:
pulleys - Order over the phone from Axminster. As per the Charnwood pages above there is compatibility between Axminster and SIP lathes. it seems the 01940 has a lot of overlap with my earlier 01490 so I expect the pulleys to fit. Delivered was
£53. Here is the contact page:

bearings - on mine the first is spec 60072RS -
60 indicates it's a part of the "6000" series, which are generally single-row deep groove ball bearings. The
07 represents a 35mm inner diameter and the
2RS represents 2 rubber seals. Full spec is 35mm inner diameter, 62 outer and 14mm width
loads to choose from on ebay, 1 needed for the moving pulley on the spindle - 1 for less than £5 on ebay
Also 2 more bearings needed for the spindle,
5205 RZ 52mm outer, 25mm inner and 15mm width - ebay about £10 each
Belt - its a Z23 belt which specifies a v-belt with 6mm inner width, 10mm outer width and 23 = 23 inches or 584 mm internal diameter of the belt. Wait for it,
£2.58 delivered from Ebay:

I have to say you can spend way more on the promise of the best quality spares for the belts and bearings but I am not sure you get the extra value for money. Stainless steel bearings would cost more, ceramic hybrid much more but in all honesty, the potential load on the spindle could mean ceramic hybrid bearings are at risk of shock damage and I am advised to stick with metal bearings. Belts similarly, I bought 2 actually one as a spare, at 2.58 each I could have 9 belts for the price of one from the manufacturer!
Anyway hope this is helpful, best regards
