This is a bearing follower for following templates on spindle moulders with 20mm spindle such as Kity K5 535, Bestcombi etc.
New old stock, unused but tarnish to the surface from sitting in storage. The bearing is smooth it's just the aluminium has slight coating to it which doesn't affect it. Quality SKF bearing.
96mm diameter for use with euro blocks etc. Ideal match for the 96mm kity block although can be used with other sizes by allowing offset in the template.
Other sizes available.
