Autotronics, Inc. manufactures a line of internal bearing pullers for use on miniature bearings with inside diameters ranging in size from 1/16 to 3/4 in.; metrics include 2.5mm to 11mm. These pullers are especially effective for blind holes where two or three arm pullers cannot be used.
The use of a puller minimizes impact damage and lessens the incidence of brinnelled bearings and damaged raceways. Autotronics bearing pullers are made from high tensile strength hardened tool steel, have knurled handles, and are for metric and inch diameter bearings.
Pullers are available individually or in sets. The sets are defined by size. The sizes are: 3/32″, 1/8″, 3/16″, 1/4″ and 5/16″ for the small English set and 3mm, 4mm, 5mm, 6mm, and 7mm for the small metric set. The large English set comprises 3/8″, 1/2″, 5/8″ and 3/4″, while the large metric set includes 8mm, 10mm, 12mm, and 15mm pullers.
