Last week I bought four races and seals for my 1983 SBS Trailer for £31 from Townsend Bearings Unit 1St Andrews Industrial Est.Bridport DorsetDT63EX email sales@townsendbearings.co.uk
Very good value compared with suppliers in Exeter approx 1/2
Their code L44649/10(inner race) LM48548/10(outer) with appropriate seals They are extremely helpful
